There's an excess of Phosphorus in soil, the plants consume it, then the primary consumers consume multiple plants, and have a higher level of phosphorus concentration in them. Then secondary consumers consume multiple primary consumers and the phosphorus from all the things they ate are concentrated in them, and so on. Basically, even though as energy is passed along the food chain, it lessens with each trophic level, nutrients become more concentrated and the highest trophic level has the highest concentration because of how many organisms were consumed.

If a population with two alleles is at Hardy-Weinberg equilibrium ad the frequency of one allele is 0.7, what is the heterozygot
Vinil7 [7]

Answer:

B. 0.42

Explanation:

Since the two alleles are at Hardy-Weinberg equilibrium, the sum of the frequency of two alleles will be one. If the frequency of a dominant allele is "p" and that of the recessive allele is "q", then p+q=1

According to the given information, the frequency of one allele in the population is= 0.7

This means that the frequency of the other allele would be= 1-0.7 = 0.3

Frequency of heterozygote in the population =2pq = 2 x 0.7 x 0.3 = 0.42

Mariulka [41]

Answer:

the point of science is to disprove hypothesis so having a hypothesis that doesn't allow that to happen is not good science

2. they don't fit in our mouths so are a trait from when we had larger jaws

3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)

4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would

5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.
