Most of the oxygen exiting the blood and entering the tissues does so from the capillaries.
Answer: Option D
<u>Explanation:</u>
The circulatory system consists of the heart, arteries, veins and capillaries. An artery is the one which carry blood from the heart to the organs. A vein is the one which carry blood from the organ to the heart.
A capillary is the smallest blood vessel which helps connect the functions of arteries and veins in the body. The capillaries are the narrow tubes which allow diffusion of Oxygen into and from the tissues. It’s prior function is to drop Oxygen in a tissue and collect the Carbon dioxide from the tissue.
Coronary artery.....are the arteries that provide blood to the wall of heart !
They are the managed consumption of natural resources to prevent their depletion or the destruction of the environment.
Answer:
a. hox genes.
Explanation:
HOX genes have the following functions:
- HOX genes are the homeobox subset.
- They specify the areas of the embryo's body plan along the animal head-tail axis.
- They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.
- They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.
The vertebrates are highly preserved.
The clusters and other genes occur uninterrupted.
Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.
The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.
Answer:
C: Met, Pro, Leu, Thr
Explanation:
AUG is met
CCA is Pro
UUG is Leu
ACG is Thr
The first letter is on the left side
Once you have that row, the second letter is on top
Then look for last the three letters in that box
