Why do vertebrate embryos show similarities between organisms that do not appear in the adults?
yKpoI14uk [10]

It is believed that this happens because some signals that regulate development are the same between different species and because <span>they share ancient genes. </span>These ancient genes are expressed during a middle "phylotypic stage" of embryonic development for all species.

For example,  human and animal embryos go through very similar stages of early development and share similar features such as tails and gill-like structures. The major difference appears to be how long it takes to reach each of these same stages.

Value: 1
Jobisdone [24]

Answer:

I believe the answer is 3/4

Explanation:

18 and 24 both have common factors of 6. So you would divide both 18 and 24 by 6. 18÷6=3 and 24÷6=4. 3 and 4 don't have any common factors so this is the lowest it can go and can't be divided anymore. So, 3/4 is the simplest form. Hope I helped! :)

Answer:

DNA

proteins

genes

chromatin

chromosome

Explanation:

The “code” for physical traits is found in a molecule called DNA. Segments of this molecule that code for specific proteins are called genes. In order to conserve space and protect the molecule, DNA wraps around proteins to form chromatin. When a cell is about to divide, DNA wraps up even tighter into  chromosomes.  Complex organisms have many molecules of DNA in every cell, and each molecule is commonly referred to as a chromosome, even if it is not wrapped up as one.
