What is ONE major difference in the problems associated with obtaining measurements on the sizes or densities of animal populati

ratelena [41]

I think one major difference with that is that animals can move around, go distances in search for food or mate, and thus make the animal densities per geography vary greatly. Birds migrate regularly, so their population densities tend to vary with seasons. Their mobility also depends on the availability of food, so animals go away if there are no food in the area.

Plants on the other hand don't move around faster (they can migrate by reproduction: it's their seeds moving around). Thus their densities tend to be more constant per season/life cycle.

Answer:

16% is G

12% is T

12%is A

22% is X

Explanation:

Given that each nucleotide is complimentary to another nucleotide, there cannot be more of one than the other. For example, C bonds to G, so there cannot be more C than G, because there would be nothing for it to bond to.

So if there is approximately 16% of the genome composed of C, that would mean that approximately 16% is composed of G (for it to bond to).

The same logic can be used to determine the amount of nucleotide X is present. If Y binds to X, and approximately 22% is composed of nucleotide Y, then the same percentage can be given to nucleotide X, and say the amount of X is 22%.

Now all of the nucleotides have to add up to 100%, so:

A + T + G + C + X + Y = 100%

A + T + (16%) + (16%) + (22%) + (22%) = 100%

A + T = 24%

Given that A binds to T, they must be equal to each other, hence we can say that the concentration of A, equals the concentration of T.

Therefore, the concentration of A is 12%, and the concentration of T is also 12%.

Citrus2011 [14]

Answer:

The answer (Image 1) is attached. Since the options weren't provided, I've attached the image of the options, too.

Explanation:

The plasma membrane is composed of phospholipids, a special form of lipids with a hydrophilic head and hydrophobic tail. According to the fluid mosaic model, the hydrophilic heads are positioned towards the outside where they freely interact with the extracellular matrix and cytosol. Whereas, the hydrophobic tails are positioned towards the inside so they aren't exposed to water.

Liposomes are lipid bases particles used for drug and vector delivery. The picture shows a typical liposome.

In the current case, for water to move both outside and inside, hydrophilic heads should be present inside as well as outside the tails.
