I know the strands are DNA , but the answer is duplication because it adds one or a pair of chromosomes. i hope i helped u :) and plzz may i have brainliest ?
Answer:
Cells grown in culture tend to adhere to each other, through adhesins, so they are able to communicate with each other. They form gap junctions that allow the cytoplasm of the cells to exchange some molecules such as cyclic-AMP associated molecules in this case.
Therefore even though the FSH binds to the receptors on the ovarian follicle cells only (since these are the cells that bear the receptors for the hormone on their surface), the pathway and associated molecules for secondary messengers can diffuse across the across the gap junction into other cells, including those of the cardiac cells, hence inducing some contraction in these cells, as they respond to the secondary messengers.

Answer:
A
Explanation:
Pumps move substances through the plasma membrane.
Answer:
(B) Lava has separated the population into two areas: an upland forest and a lowland marsh.
Explanation:
In allopatric speciation, individuals of an ancestral species may undergo evolution into two or more progeny species which arises when physical separation causes a geographic boundary, this barrier can be in the form of a mountain range, rockslide, river or lava.
As in this scenario, a lava flow divides the populations of annual herbaceous plants by altering the landscape. This will cause genetic divergence with varying heritable features among its many generations favouring different traits in the separate environment along with genetic drift. The Lava will separates the population into two areas: an upland forest and a lowland marsh.
Fracking process is dangerous and hazardous for all our environment and its organisms.
<h3>What is your opinion about fracking?</h3>
Hydraulic fracturing is a type of oil and gas drilling that occurs across the country. Due to no safety regulations, it can polluted groundwater, pollute surface water, and harm wildlife.
So we can conclude that fracking process is dangerous and hazardous for all our environment and its organisms.
