The answer is dormancy

Right away we can tell that dispersal is not the answer. It simply refers to how plant seeds are spread around. 

That leaves us with fertilization, germination, and dormancy. 
Fertilization refers to the union of the male and female reproductive cells which form a fertilized egg. However, the embryo is not alive at this point yet, so we can move on to the next answer choices. 

Germination, this is the actual growth of a seedling from the seed. We are looking for a period in which is not growing so by its very definition, germination cannot be the answer. 

Lastly, we have dormancy. 

Dormancy is a period in which the embryo is dormant. Think about a dormant volcano. There is magma within the volcano, and it is considered "alive" but it does not erupt. Similarly, a dormant embryo of a seed is one that is alive but simply isn't growing. This typically happens during winter. Almost as if it undergoes hibernation.

What membrane activities requires energy from atp hydrolysis?
NikAS [45]

Answer:

active transport, like Na + ions leaving the cell

Explanation:

The active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, just as the diffusion facilitated the active transport is limited by the number of transport proteins present.

Two major categories of active, primary and secondary transport are of interest. The primary active transport uses energy (generally obtained from ATP hydrolysis), at the level of the same membrane protein producing a conformational change that results in the transport of a molecule through the protein.

The best known example is the Na + / K + pump. The Na + / K + pump performs a countertransport ("antyport") transports K + into the cell and Na + outside it, at the same time, spending on the ATP process.

The secondary active transport uses energy to establish a gradient across the cell membrane, and then uses that gradient to transport a molecule of interest against its concentration gradient.

which structure of the respiratory system plays the main role in carry out the system’s primary function? trachea pharynx alveol
baherus [9]
The main function of the respiratory system is to allow the exchange of gases between the atmosphere and the lungs.
Hence,the only structure that carries out this function is the alveoli as other structures such as the nose,trachea and pharynx transport gases to the alveoli just so that it can can out its function.

What is cell surface to volume ratio and why is it important in cell functioning? Can it explain why cells are so small?
MrMuchimi
<span>The main reason surface area to volume ratio is important to a cell is because the surface area to volume ratio determines the rate at which cells uptake nutrients, liquids or gases. For instance, I have two organisms, A and B. Organism A has a surface area to volume ratio of 6:1, whereas organism B has a surface area to volume ratio of 3:1. As organism A has a greater surface area to volume ratio, it means that organism A will be able to take up nutrients, liquids or gases via diffusion or osmosis at a greater rate than organism B, as it has more surface with which to exchange nutrients, liquids or gases. </span>

what process involving cell division results in daughter cells that are not identical to the parent cell?
andre [41]

Answer:

meiosis

Explanation:

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Why does the fishing industry watch for upwellings eagerly?​
vazorg [7]

Answer:

Due to the fact that the Upwelling brings all of the nutrients and food for the fish to the surface which is where all the fish will be feeding. ... Compare rivers and surface currents. Both rivers and surface currents are long, moving bodies of water.
