I don’t know the answers but if you search up the first question on google the second/third link should be the quizlet with the answers
Stem cells. Or more specifically, embryonic stem cells.
The blood vessels farthest from the heart must have valves.
The valves which are present in the blood vessels prevent the backflow of the blood back into the specific organ.
There are different valves present in the heart are:
- The tricuspid valve is situated between the right atrium and right ventricle.
- The pulmonary valve is between the right ventricle and the pulmonary artery.
- The mitral valve is between the left atrium and left ventricle.
- The aortic valve is between the left ventricle and the aorta.
Other vales which are present in the blood vessels are in leg. Leg veins do require the valves. If not present the blood will go back down into the feet because of the gravity. Thus there are various valves present in the leg veins.
Valves in veins are bicuspid, meaning they have two flap-like structures that regulate blood flow in the vein.

Answer:
The population will decrease or also have the mutation if its able to be passed on
Explanation:
because the deer is missing a toe it cannot run as fast, this means that it will most likely be killed. Because the deer was born with it it is a hereditary mutation. Which can be passed on. That means it's offspring will also have the mutation making the population fragile.
- Watersheds
Streams and creeks are examples of " watersheds". Aquifers and ground water are related to each other because both of them are located under the earths surface. You have to dig in order to acquire these two. Watersheds are just like catch-basins where water are stored or being flowed.
