Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.
There is four kingdom in the domain eukarya.
Domain eukarya is made of eukaryote organism. Domain eukarya has 4 kingdom: Protista, Fungi, Plantae and Animalia. The member of Plantae is autotroph organism that has chlorophyll and capable of doing photosynthesis. Fungi has cell wall that made of chitin. Animalia doesn't have cell wall.
True...................................
Explanation:
<h3>for example:- </h3>
If a mutation led to brighter feather colouring in birds, the brighter feathers may allow those individuals with the mutation to reproduce more frequently, because they are seen as being more attractive and a desirable mate.
Because if the new species is better at doing whatever the original species does, the original species can die because they are outcompeted by the new species, and because the new species is better, they can cause a further decline of for example the food supply that they're outcompeting the original species for. This can cause problems in the entire food web/ecosystem
