<span> I. New species can outcompete native species to fill a niche.
</span>

Niche is like a profession because everybody in our world performs a different job. Niche is somewhat defines like what you do, how you do it, where you do it and when you do it.In ecology, a niche is a term about the relational position of every species like dolphin. In where dolphin can potentially be in another ecological niche by travelling from one place to another. Profession are something like finding your specialty, your place and your niche in the world.

5. The permease (transporter) allows glucose and Na into the cell requires ATP. True or False?
dem82 [27]

Answer: 5. False 6. False

Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.

When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.

The transport mechanism is carrier mediated it does not require energy.

More solar energy reaches the equatorial regions than the polar regions because the equatorial regions
crimeas [40]


The answer is that the equatorial regions receive sun rays closest to the vertical (direct rays) because of their position relative to the equator where the tilting of the earth only mildly affects the climate. The climate along the equator  changes very little through out the year and has summer like conditions for  most of the year.

However the other regions may receive direct sun rays but for far more limited periods.  In the months of July and August (summer months), the northern hemisphere is tilted towards the sun and receives the most  direct  rays. The opposite occurs in December and January when it is tilted away from the sun and thus winter sets in, whereas the southern hemisphere is at this time tilted toward the sun and receives the most direct sun rays.

Suppose a geneticist isolates two bacteriophage mutants. One mutation causes clear plaques (c), and the other produces minute pl
Nesterboy [21]

Answer:

The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.  

Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.  

The total recombinants from 1000 plaques will come out to be 80,  

Thus, the recombinants of each type will be 40.  

Total parental type will be 920, and therefore, each parental type count will be 460.  

Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.
