Answer:
What is true of natural selection? A. Natural selection is a random process. B. Natural selection creates beneficial mutations. C. The only way to eliminate harmful mutations is through natural selection. D. Mutations occur at random; natural selection can preserve and distribute beneficial mutations.
The answer is D
Explanation:
natural selection can simply be explained as individuals that have specific inheritable traits will most likely tend to adapt and survive and as well reproduce at higher rates than others. mutation occurs when the nucleotide sequence of an organism changes. so natural selection can preserve and distribute beneficial mutations.
<span>The similarities between an onion and whitefish cells exist in the cell division process. Normally the basic process of mitosis cell division is similar for plant cells and animal cells, but there are fundamental differences that mark the mitosis of plant and animal cells. Basic similarities of onion cell and that of whitefish embryo cell is that in the four phase of mitosis namely, Prophase, Metaphase, Anaphase and Telophase occurs in similar way. In Prophase for both cells the chromatin condensed and in metaphase the chromatin aligns in the center of cell and kinetochores of chromosomes attached with the microtubules of spindle from opposite poles. In Anaphase stage, the chromatids from the metaphase plate are separated and shifted to opposite poles.. Finally at Telophase, the cell divides via cytokinesis. The fundamental difference between Onion cells and Whitefish cells can be found in the process of cytokinesis.

I think the nuclear membrane begins to break down, and the pair of chromosomes look like their are floating in the air.
Answer:
The three lines of defense model enhances the understanding of risk management and control by clarifying roles and duties. The model provides guidance for the implemented structure and the assigned roles and responsibilities of parties to increase the effective management of risk and control
Explanation:
the first line of defence – functions that own and manage risk. the second line of defence – functions that oversee or specialise in risk management, compliance. the third line of defence – functions that provide independent assurance, above all internal audit.
