of the circulation process?
• A. The blood releases carbon dioxide on the way back to the heart.
•
B. The blood goes through the liver to be cleaned.
O C. The blood travels back to the heart in a vein.
• D. The blood travels to the lungs to get oxygen.
Are there any parts of the human body that get oxygen directly from the air and not from the blood? Are there nuclear reactions going on in our bodies?
Answer:
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.
Nuclear reactions do indeed occur in the human body, but the body does not use them.

How is the reproductive rate of marine mammals
related to their status in regards to extinction?
Answer:
The fewer fish the less that can reproduce.
Explanation:
marine mammals with a slower reproductive rate are especially sensitive to disturbance , environmental changes and anthropogenic sources of stress because when populations of these organisms decline, recovery is especially slow . it takes a significant amount of time for these animals to reach reproductive maturity and they are commonly heavily invested in raising only one or two young ones every two to three years on average . therefore , populations of marine mammals with slow reproduction are in imminent danger when multiple sources of envirnmental pressure are acting in tandem over an extended period of time . The fewer fish the less that can reproduce.
More the reproductive rate, lesser the extinction and lesser the reproductive rate, more is the extinction.
What is reproductive rate?
The reproduction rate measures the conditions under which generations are replaced. This calculation can be made taking account of mortality (net reproduction rate) or without mortality (gross reproduction rate).
What is extinction?Extinction is a situation in which something no longer exists.
When the reproductive rate of marine mammals will be less, they will not be able to cover up the loss/death of their species caused by any reason and will ultimately lead to extinction.

At stage 3, it is most difficult to tell the embryo apart. This is because There are a lot of similarities at this stage and the distinguishing features have not developed yet.
Each embryo has some type of tail bone, whether it may or may not be used when actually born.
This can be used to support evoultion because the similarities clearly and visibily show a common ancestor between embryos. Because of their obvious similar traits, embryos must share ancestral DNA that they evolved from.
