Answer:
Negative feedback
Explanation:
Feedback mechanism is activated due to the change in the system that result into an output.
A negative feedback mechanism is a pathway that is caused by deviation in the output that result in a change in output direction which is usually opposite to the initial deviation.
The process of feeding of sea lamprey on the fish started as a normal pathway the deviation started when they could not feed on the fish again as a result of reduced population and they start dying of hunger. It is a negative feedback
Answer: AUG,UGG,AAC,CGC,UGC,UGA
Explanation: DONE IT1
Answer:
The correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
Explanation:
Scientists could not use DNA evidences to make a complete phylogenetic tree of Icthyosaur as there are no blood samples or other DNA molecules to create DNA printing or mapping to create phylogeny with the modern dolphins. They only can be make similarities based on the morphological characteristics of these two groups.
Thus, the correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
Answer:
A. DNA repair
Explanation:
The p53 protein acts as a tumor remover by controlling a set of genes required for the cell division. This protein protects the genome by <u>restricting abnormal cells to proliferate</u> avoiding the replication of damaged DNA. The first resource the protein uses and prometes is DNA repair and if the DNA has irreparable damage, t<u>he last resource used by this protein is</u><u> apoptosis</u>.
