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.
In order to determine the ratio, we simply make the fraction:
Number of blue triangles / number of yellow triangles
= 5/80
Next, we simplify the numerator and denominator using the highest common factor, which is 5.
= 1/16
Therefore, the ratio of blue triangles to yellow triangles is 1 to 16.
Answer:
Bother the heavy and light ball would fall at the exact same rate and at the same time.
Explanation:
Both of the balls will hit roll down the ramp at the same time and at the same speed as long as there are no other variables that would change the result such a the air resistance level and as long as it the same ramp. Galileo helped out with this answer in the science world because he wanted to see whether or not a bowling ball and a feather would fall at the same time. Although Galileo tested that in a vaccum, it allowed us to experiment it with other objects which allowed up to see the astonishing results. Gravity will make everything accelerate downward at exactly the same rate, no matter how heavy or light the object is.
