Cytokinesis occurs after mitosis is complete. It is when two daughter cells are formed, each with their own nuclei, after a single cell has <em>completely </em>divided.
Answer:
energy pyramid
Explanation:

Answer:
Its (D) Volcanic Eruption
Explanation:
Answer:
Aa
Explanation:
In Punnett Square, you are bringing the letters on the top to the numbered squares, if that makes sense. It is to predict the genotype of offspring.
So square 1, on the left is A, and on the top is A, so it would be AA.
For square 2, on the left is a, and on the top is A, so it would be Aa.
For square 3, on the left is A, and on the top is A, so it is AA.
Square 4, your question, has a on the left, and A on the top, so it is Aa.
Hope it makes sense. You should probably watch a Punnett Square tutorial online or something for a full and more general explanation.
Answer:
Repressor protein
Explanation:
Repressor is a protein that binds to deoxyribonucleic acid(DNA) or ribonucleic acid(RNA) it inhibits the expression of one or more genes which is done by binding to the associated silencers.
A DNA binding repressor works by blocking the attachment of RNA polymerase an enzyme that enhance transcription to the promoter, thus preventing genes from been transcribed into messenger RNA.
An RNA binding repressor binds to the messenger RNA and prevents translation of the bases on the messenger RNA into protein. The blocking of expression is called repression.
