Answer:
Explanation: In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into or out of, the cell by moving down it.
Unfortunately this question is incomplete as it is a multiple choice question. The following options are provided:
<span>A) body cavity between body wall and digestive system
B) number of embryonic tissue layers
C) type of body symmetry
D) presence of Hox genes
E) degree of cephalization
The answer is D: presence of Hox genes

Hox genes are a group of genes that determine the basic structure and orientation of animals.
Answer:
Recombinant DNA can replace a gene in an animal’s genome.
Explanation:
The molecular cloning process involves in creating Recombinant DNA. This DNA is used to replace or replicate any specific gene. This is done by the process of PCR to replicate it directly.
This formation is done in the presence of a vector. This method is used in the field of veterinary office, pharmacy and many more. It has the ability to replace the gene of an animal’s genome.
I believe it is the first one but I am not 100% sure
