2) Hormone proteins co-ordinate bodily functions, for example, insulin controls our blood sugar concentration by regulating the uptake of glucose into cells.
hope its what ur looking for XD
Answer:
4
Explanation:
<em>The number of progeny expected to display the dominant phenotype for both the A and B genes should be 4.</em>
<u>A test cross usually involves crossing an individual whose zygosity is in doubt with an individual that is recessive for both alleles so as to ascertain the zygosity of the former.</u> Hence, for a test cross involving AaBb:
AaBb x aabb
Progeny:
4 AaBb
4 Aabb
4 aaBb
4 aabb
<em>Therefore, the number of progeny expected to display the dominant phenotype for both the A and B genes is 4.</em>
The answer is D. Bacterial calls do not have chloroplasts or cell walls, but both have cell membranes ribosomes, and a nucleus.
Answer:
The correct answer is - C. retention of their own genome.
Explanation:
The endosymbiotic theory is a theory that suggests that eukaryotic cells are developed from prokaryotic cells. According to this theory, organelles like mitochondria are developed in eukaryotic cells as the result of proteo-bacteria cells engulfing aerobic bacteria.
The evidence of this theory can be seen as the mitochondria has their own genome such as circular DNA and ribosomes as the prokaryotes.
