How are food webs different to food chains? Explain why foodwebs are more useful

Biology
1 answer:
mojhsa [17]3 years ago
3 0

Answer:

Explanation:

A food chain is different because it shows what organisms eat in a straight line, in a chain. For example, a bird of prey can eat a snake that previously had eaten a frog and the frog ate a grasshopper and so on. But this tells us very little. A foodweb will tell us how all those animals are connected and what they eat in a web, not just a line.

7.   Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If
Oksi-84 [34.3K]

Hi!

The correct answer would be A.

<h3>Explanation:</h3>

As the allele P for polka dot is dominant to the allele p for solid color, it would yield a Polka dot tail in the individual in the presence of just one allele of P, while masking the effect of p for solid color.

So the possible genotypes and phenotypes would be as follows:

  1. PP (Polka dot tail)
  2. Pp (Polka dot tail)
  3. pP (Polka dot tail)
  4. pp (Solid color tail)

Following a cross by two heterozygous individuals, there would be 25 percent chance (1/4) of having the genotype pp , 25 percent (1/4) chance of having the genotype PP and 50 percent (2/4) chance of having the genotype Pp.

But the phenotype yielded by Pp and PP offspring would be polka dots, so there is a 75 percent (3/4) chance of having polka dot offspring, and 25 percent chance of having solid colored tail offspring.

<h3>Hope this helps!</h3>

Movement of fluids and solutes out of capillaries into the interstitial fluid occurs by filtration, which is driven by capillary
Elodia [21]

Answer:

The correct answer will be- interstitial fluid hydrostatic pressure

Explanation:

The exchange of fluid between the tissues and the capillaries is determined by the hydrostatic pressure which refers to the pressure exerted by any fluid in an enclosed space.

The pressure exerted by the blood on the walls of the capillary vessels is known as the capillary hydrostatic pressure which is responsible for the exchange of the fluid between tissues and the capillaries.

During the exchange of the fluid from the capillaries to the issues the hydrostatic pressure of the interstitial fluid rises which is known as the interstitial fluid hydrostatic pressure. This pressure opposes the fluid exchange so the capillary hydrostatic pressure is usually found higher than the interstitial fluid hydrostatic pressure.

Thus, interstitial fluid hydrostatic pressure is the correct answer.

a person with genotype uu vv xx yy zz can have the same phenotype as a person with the genotype uu vv xx yy zz? true false

True
Genotype determines the phenotype and if the genotypes are the same, then the phenotypes will be the same as well.
