Answer:
Many cellular processes use similar mechanisms to achieve different goals.
Explanation:
<em>Metabolic pathways are series of enzyme-catalyzed reactions. Enzymes interact to remove and add phosphate groups to molecules or to move protons across a membrane. The same as in cell signalling, where the receptor proteins interact with specific molecules and often remove or ad phosphate groups. The phosphorylation of receptor proteins is very close to the process steps in metabolic pathways but with a very different function. </em>
<em>In metabolism phosphorylation is a method of transferring energy, in cell signalling it transmits information.</em>
Correct answer: D). DNA technology can increase genetic diversity by producing more variant alleles.
The genetic diversity can be increased by the mutation that creates new alleles in the population. The recombinant DNA technology enables the joining of DNA from the two or more than two sources that allow changing the genetic composition of the living organism. The genetic diversity helps the population to adapt to the changing environment.
Hence, the correct answer would be option D.
B) Octopuses ability to squirt ink
Answer:
Option A
Explanation:
Your answer is option A or the "stamen." The stamen is a reproductive organ of a flower that produces the pollen. When a bee visits for a meal of nectar the stamen is the part of the flower that deposits pollen on the bee's body. It's not option B because the sepal functions as protection for the flower, and it's not option C because the petals main purpose is to attract the bees to the flower to pollinate.
Hope this helps.
