Welcome to another post on my blog. For Biology, we are looking at Medical Science after finishing Nutrition and Digestion. The second part of Medical Science is Muscles and Joints. I hope you like it.
Welcome to another post on my blog. I am going to share the second activity that I completed in Biology. In that activity, we had to watch the video: Why do joints click? And explain what causes joints to click. All information is from the, 'Why do joints click?' and 'Here's what happens to your knuckles when you crack them' video.
The most common explanation on why your joints sound like bubbles popping is well, there are bubbles in there. When you stretch out that joint, you are releasing gas, and that gas forms a bubble, it collapses and pops. The joints in your fingers are the easiest to crack, but many people also crack their hips, wrists, shoulders, necks, shoulders and so on.
Knuckle-crackers know that to get that satisfying pop, you stretch the joint farther than it normally goes by bending your fingers backwards, for example, when that happens, the bones move away from each other. The space between the bones gets bigger, but the amount of synovial fluid stays constant. That creates a low-pressure zone, that pulls dissolves gases out of the synovial fluid, that pulls dissolved gases out of the synovial fluid, just like the carbon dioxide that fizzes out of soda when you twist open the cap. Inside the joint, the escaping gases from a bubble with a pop.
The reason knuckle cracking is like that because it contains lots of dissolved gas molecules, like other fluids in your body. But the bubble doesn’t last long. The surrounding fluid presses on it until it finally collapses. The bubbles gases scatter throughout the synovial cavity and slowly dissolve back into the fluid. In order to crack the same muscle again, you have to wait for around 20 minutes for the gas to return back to that fluid.
Some scientists think there may by two pops. One when the bubble forms, and other when it bursts. Dr Donald Unger was a self-described researcher who chose to pop the joints in one of his hands for 50 years but not the other one and he wanted to find out if popping your knuckles would actually five your arthritis. After 50 years of doing it, he found that he didn’t have any more arthritis in one hand than the other.
There is still a chance it’s not good for you. One 1990 study did find that cracking your knuckles over a long period of time led to hand swelling and decreased scrip strength, but there hasn’t been any follow-up research on that. While knuckle cracking might not be bad for you, there’s still no guarantee that your popping habit won’t annoy the people around you.
Welcome to another post on my blog. I am going to share the activity that I completed in Biology. In that activity, we had to watch the video: How Bones Grow, and answer some questions.
What are the materials used to make and reinforce bone? How does it work?
All information is from the, 'How Bones Grow' video.
Osteoblasts, the makers, have a counterpart called osteoclasts, the recyclers. Osteoclasts break down the unneeded mineral lattice using acid and enzymes so that osteoblasts can then add more material. As calculated by Wolff’s Law, that makes osteoclasts more active than osteoblasts, ending in a loss of bone mass and strength. When bones break, the body has an amazing ability to repair the bone as if it never happened.
First, doctors extract stem cells from the patient’s fat tissue and take CT scans to find the exact dimensions of the missing bone. Next, they model the exact shape of the hole, either with 3D printers or by carving with decellularized cow bones. Those are the bones where all of the cells have been stripped away, leaving only the sponge-like mineral lattice. They then add the patient's stem cells to this lattice and place it in a bioreactor, a device that will simulate all of the conditions found inside the body. Temperature, humidity, acidity and nutrient composition all need to be just right for the stem cells to differentiate into osteoblasts and other cells, colonise the mineral lattice, and remodel it with living tissue. Remember Wolff’s Law? An artificial bone needs to experience real stress, or else it will come out weak and brittle, so the bioreactor constantly pumps fluids around the bone, and the pressure tells the osteoblasts to add bone density. Put all of this together, and within three weeks, the now living bone is ready to come out of the bioreactor and to be implanted into the patient's body.
Welcome to another post on my blog. For Biology, we are looking at Medical Science after finishing Nutrition and Digestion. The first part of Medical Science is bones and the skeleton. I hope you like it.
Welcome to another post on my blog. In today's post, I am going to share you my guide to the Digestive System. The last lesson in Biology, we had to cut out the paper body parts and then stick where it should be, label them and write two facts about that part.
I've also made a slide show explaining the parts of the digestive system.
I hope you learnt something new and liked my post. Have a cool day!! Bye!!
Welcome to another post on my blog. In today's post, I am going to share the experiment that I've done in Biology today. I had to do the experiment myself.
Aim: To test if a sample of food contains complex sugar, simple sugar and protein.
Hypothesis: I think that it will have all of Bread Meat Cheese Pickle
Will all change colour.
Equipment:
Complex Sugar:
Test Tube
Food Sample
Iodine Solution
Simple Sugar:
Water Bath
Test Tube Tongs
Benedict's Solution
A Sample of Food
Protein:
Test Tube
Sodium Hydroxide (NaOH)
Copper Sulfate (CuSO4)
Food Sample
Method:
Complex Sugar:
Place about 2 ml of sample in a test tube.
Add 3-5 drops of iodine and mix.
Simple Sugar:
Place about 2ml of the sample into a test tube and then add 5 drops of Benedict's Solution.
Heat with a hot water bath until it changes colour.
Protein:
Place about 2 ml of the sample into a test tube and add 5 drops of sodium hydroxide.
Add 5 drops of copper sulfate.
Shake the test tube gently from side to side.
Results:
Complex Sugar:
Bread has complex sugar. Meat doesn't have complex sugar. Cheese doesn't have complex sugar. Pickle has complex sugar.
Simple Sugar:
Bread is a simple sugar. Meat is not simple sugar. Cheese is not a simple sugar. Pickle is a simple sugar.
Protein:
Bread is not protein. I'll update the rest as soon as possible.
Conclusion:
In conclusion, my hypothesis didn't get all correct except some of them, like, meat, cheese and bread (in protein). What I had learnt in this experiment is that meat and cheese do not have complex or simple sugar.
Welcome to another post on my blog. In today's post, I am going to share the experiment that I've done in Biology today. I had to do the experiment myself.
Aim: To test if a sample of food contains protein.
Hypothesis: I think that in the; Glucose - is not going to change colour. Apple - is going to change colour Bread - is not going to change colour. Potato - is not going to change colour Egg - is not going to change colour. Milk - is going to change colour. Equipment:
Test Tube
Sodium Hydroxide (NaOH)
Copper Sulfate (CuSO4)
Food Sample
Method
Method:
Place about 2 ml of the sample into a test tube and add 5 drops of sodium hydroxide.
Add 5 drops of copper sulfate.
Shake the test tube gently from side to side.
Results:
First, our teacher had tested the potato. After adding the potato in the test tube, she added 5 drops of sodium hydroxide. Then added 5 drops of copper sulfate. In my hypothesis, I had written that it is not going to change colour. Well, it really didn't change colour. Because it is not a protein food.
Secondly, the apple was tested. In my hypothesis, I wrote that it is not going to change colour, because it is not a protein. My hypothesis was right. It didn't change colour.
Thirdly, milk was tested. I had written in my hypothesis was that 'milk is going to change colour'. Because milk has got protein. Again, my hypothesis was right, it changed colour to protein.
Because we didn't have egg, we didn't test it out. But what I'd written in my hypothesis was that egg is not going to change colour. Well, it did change colour, which I had learnt.
The fourth test was the bread, I had written that bread is not going to change colour. Luckily, I was right and it didn't change colour. I knew that the bread didn't have protein.
The last test that was tested was glucose or sugar. I had written that sugar wasn't going to change colour because it hadn't had any protein in it.
Conclusion:
The experiment was really well done and I'd learnt something new. We had tested 5/6 samples of food. From my hypothesis that I had written earlier, I had got 4/5 or 80% of my hypothesis correct, which was really good.
Welcome to another post on my blog. In today's post, I am going to share the experiment that I've done in Biology today. I had to do the experiment myself.
Aim: To test a sample of food to determine whether it contains simple sugars.
Hypothesis: I think that in the; Glucose - it might change colour because it can be any simple or complex sugar. Apple - it will change colour because it is a carbohydrate (sugary) Bread - it might change colour. Potato - it won't change colour. Egg - might change colour. Milk - won't change colour.
Equipment:
Method
Water Bath
Test Tube Tongs
Benedict's Solution
A Sample of Food
Method:
Place about 2ml of the sample into a test tube and then add 5 drops of Benedict's Solution.
Heat with a hot water bath until it changes colour.
Results:
What I observed is that every sample changed colour except,
We first got the apple, potato and bread and put it in the test tube. Next, we had put 5 drops of solution.
Adding Benedict's Solution into a small piece of potato
Next, we put the three test tubes in the hot water bath until it changes colour. We put three test tubes into two beakers with hot water.
Hot Water Bath
What I found out weird that the egg had changed colour too! Because I wasn't sure if it was going to change colour or not.
Conclusion:
My experiment worked really well. I am not sure if I got the hypothesis right or wrong because I mostly had written: "might".
Welcome to another post on my blog. In today's post, I am going to share the experiment that I've done in Biology today. I had to do the experiment with a pair.
Aim: To test if a sample of food contains complex sugars.
Hypothesis: I think that in the; Glucose - won't change colour because it is a simple sugar. Apple - won't change colour because it's also a simple sugar. Bread - will change because it is complex sugar. Potato - will also change colour because it is complex sugar. Egg - it might have simple sugar or complex sugar because it's protein. Milk - it might have simple sugar or complex sugar because it's also protein.
Equipment:
Test Tube
Food Sample
Iodine Solution
Method:
Place about 2 ml of sample in a test tube.
Add 3-5 drops of iodine and mix.
The Bread
Results:
First, we tested the bread. From my hypothesis, I had predicted that bread is complex sugar. When we had tested the bread with the iodine, it changed colour because it was complex sugar. It changed the colour to black.
Secondly, I tested the apple. What I wrote in my hypothesis, that it won't change the colour because it is a simple sugar. But, actually, it changed colour, so apple is complex sugar. It changed the colour to dark green.
Apple
Potato
Glucose
(Sugar)
Egg
Thirdly, I tested the potato. According to my hypothesis, I had written that the potato will change colour because it is complex sugar. Actually, my hypothesis was right, it had changed colour because it was complex sugar.
Next, we had tested glucose (sugar). From my hypothesis, I had written that it won't change colour because it is a simple sugar. I couldn't tell if it was or not because what I could see was iodine.
After glucose, we had tested the egg. From my hypothesis, I guessed that it might or might not change because it's protein. This test was similar to the last one, I couldn't tell because what I could see was iodine.
Lastly, we tested the milk. From my hypothesis, I had written that it might change colour or not because it's protein.
Conclusion
In conclusion, my hypothesis was 50% correct, it's okay because there are no right or wrong answers in the hypothesis. From the hypothesis, it is what I thought about this type of food.
What I had written in my hypothesis, is that glucose won't change colour, because it's a simple sugar. But, actually, I was wrong, which is good because I had learnt something new.
The next food that I had written about was an apple. I had written that it won't change colour, but it actually did.
The third food that I had tested was the bread. I had written that it will change colour because it's a complex sugar, which was correct.
The fourth food that I had tested was the potato. I had written that it will change colour because it's a complex sugar, which was correct.
The fifth food that I tested was the egg. I couldn't tell if it changed the colour or not, so I didn't know.
The last food that I tested was the milk. When iodine was added, it diluted slightly, but it didn't change colour. So, milk is not complex sugar.
What I observed that all of the food samples that we had tested were all complex sugars.
What I've learnt in this experiment is that glucose, apple and bread is complex sugar.
It is a scientific study of the human mind and its functions, especially those affecting behaviour in a given context or mental characteristics or attitude of a person or group.
Psychology is a study of the mind and behaviour.
The mind is highly complex, and conditions that relate to it can be hard to treat.
Thought processes, emotions, memories, dreams, perceptions, and so on cannot be seen physically, like a skin rash or heart defect.
While physical signs of some mental health issues can be observed, such as the plaques that develop with Alzheimer's disease, many theories of psychology are based on observation of human behaviour.
A practising psychologist will meet with patients, carry out assessments to find out what their concerns are and what is causing any difficulties, and recommend or provide treatment, for example, through counselling and psychotherapy.
Psychologists may have other roles, too. They may carry out studies to advise health authorities and other bodies on social and other strategies, assess children who find it difficult to learn in school, give workshops on how to prevent bullying, work with recruitment teams in companies, and much more.
