Answer: Excretory
Explanation: My grandpa went through this recently and I had to learn all about it. :(
Answer:
The correct answer is D. How closely related the two species are to each other
Explanation:
Genome maps of every individual is unique. Genome map is the order of sequence of nucleotide which is present in an organism. Comparison of genome map allow the scientist to know how much closely related two organisms are.
The map of two individuals of the same species is almost the same. Similarly, the two same species have a more similar genome map than two distantly related species because they share most recent common ancestor.
For example, humans and chimpanzees are more similar than other apes so 96% of the genome are identical between them. So the right answer is D.
B. mitochondria and nucleus
Answer:
They use a gene modification technique called CRIPSR-CAS9. The pigs have been given a gene that allows them to better regulate their own body temperature, whereby they burn fat, or at which animals consume their own fat.
Explanation:
British and Chinese scientists explained that they conducted the study by adding a mouse version of the UCP1 gene used for porcine embryos, which is used to regulate body temperature characteristic of most mammals, but not ordinary pigs.
It is problematic for pigs to maintain a stable body temperature, and this is especially complicated in pigs that are cold in the winter months because they have not been able to "store" fat.
Inserting the UCP2 gene could solve this problem.
I think the correct answer from the choices listed above is option A. Cells divide in order to maintain a surface area large enough to support their cytoplasm. When they divide, their volume decreases which enables them to obtain enough nutrient and expel wastes.
