Fungi is what decomposes things and puts nitrogen back into the ground. without the fungi plants would soon begin to run out of the nutrients they need. lack in vegetation would soon form. animals would then start to die of or migrate to different locations. so eventually you would begin to see less food and more wildlife in town because of the food shortage.

rusak2 [61]
1. The <span>conclusion that can be made about the results of your first cross between a homozygous red bull (RR) and a heterozygous red cow (Rr) is shown below : 
You supposed to make a punnet square, so (picture)
</span>Than you will get that the first generation will be 50% homozygous dominant
and 50% heterozygous which lead us to conclusion :
<span>Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote). 
</span>
2. Conclusion about the results of your second cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr) is shown in the second picture. And you can see that <span>in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).

3. Conclusion about </span>the results of your third cross between a homozygous white bull (rr) and a homozygous white cow (rr) are shown in the third picture. In this case you can see the result of <span> 100% (homozygous recessive).</span>

A team of biologists develop a new drug, and one team member hypothesizes that the drug is incapable of freely passing across th
matrenka [14]

Answer:

<em>B: The drug is a small charged molecule</em>

Explanation:

Substances can passively diffuse in and out of the cell via the cell membrane in two ways;

  • Simple diffusion
  • Facilitated diffusion

The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.

In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.

Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.

<em>Correct option: B</em>
