How do genes mix in humans?

Answers

In the X and Y chromosomes. 50% of your mom's genes are in the X chromosome, and 50% of your dad's in the Y.
Technically, it’s completely possible because DNA is just DNA. It doesn’t matter where it’s come from. In the lab, you can put jellyfish genes into mice, you can put human genes into bacteria, you can put worm genes into yeast. It’s all DNA. It’s all the same kind of nuts and bolts. If you put a gene in that’s kind of got the right bits and bobs, it will be expressed. That means it will be active and it will make a protein because that’s what genes do. They make little recipes that cells use to make different proteins. Now, that’s what genes do. The difficulty comes when you say, if you put certain genes into different species, would it give that species some new power? So for example say, if you put an olfactory receptor, something involved in smelling from a dog into a human, would a human be able to suddenly smell all these different things? The answer is probably no because one gene doesn’t just give a big characteristic like that. So, one gene is not responsible for super accurate sight or the smelling ability of dogs, or the hearing ability of foxes or something like that.

How the repertory system with following physiological requirements

Answers

For Example:
Place your hand on your ribs and inhale deeply. You’ll notice that your chest expands and your back straightens. As this occurs, air is rushing through your windpipe and branches off to either your left or right lung. After 20 to 30 more branch , branch points, oxygen in the air ends up in the alveoli where it diffuses into the liquid that only surrounds the alveoli, and slips into the blood. This microscopic gas exchange occurs rapidly, oxygen is taken into the body and carbon dioxide is totally removed from the body, and then you exhale.

How do nitrogen-fixing bacteria help cycle nitrogen through ecosystems?A. They release nitrogen into the atmosphere when they replicate their DNA.

B. They capture nitrogen from the atmosphere and convert it into forms that plants can use, like ammonia.

C. They convert sunlight into chemical energy which is then stored in the nitrogen.

D. They convert ammonia from animal feces and urine into forms that plants can use.

Answers

B that’s the nitrogen fixing bacteria’s job think of it as they “fix” the nitrogen so plants can use it
