Imagine that you are studying a very large population of moths that is isolated from gene flow. A single gene controls wing colo

r. Half of the moths have white-spotted wings (genotype WW or Ww), and half of the moths have plain brown wings (ww). There are no new mutations. Individuals mate randomly, and there is no natural selection on wing color. How will p, the frequency of the dominant allele, change over time?

Answer:

Cnidarians.

Explanation:

Cnidarians are known as the marine invertebrates, and also called as Coelenterata, they belong to phylum Cnidaria. Cnidarians include sea fans, sea pens, corals, hydra, jellyfish, and sea anemones. They belong to four classes: Anthozoa, Cubozoa, Hydrozoa, Scyphozoa.

Cnidarian captures its prey with the help of nematocysts which are thread-like tubes, coiled, and sticky. Nematocysts contain toxin by the release of this toxin corals hunt their prey, and even while they are stuck to the ocean floor.

When the polymerase chain reaction (PCR) is used to amplify segments of DNA, the sample is first heated, and then cooled, in cyc
baherus [9]

Answer:

At least 17 PCR cycles or 16 PCR cycles

Explanation:

As we know -

In one chain of  heating and cooling  of polymerase chain reaction (PCR), the strands of DNA gets doubled.

The general mathematical representation of this is

{2^n - (2 *  n)}

where "n" is the number of PCR cycles.

It is given that DNA strands  to be produced is 16 times the original quantity of DNA.

So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less  than 16 times the original quantity of DNA

Which factors affect the rate of deposition? Check all that apply. color of the sediment density of the sediment size of the sed
MakcuM [25]

Answer:

density of the sediment

size of the sediment

velocity of the agent of erosion

Explanation:

Deposition can be defined as the process of building up of sediment from chemical processes because the forces which are responsible for transporting Sediment are no longer sufficient enough to overcome the forces of gravity which is why density of the sediment, size of the sediment as well as velocity of the agent of erosion tend to affect

The rate of deposition due to the fact that

Larger and denser particles are heavier and land first before, less dense particles which cause round pieces of sediment settle more quickly than flat pieces .

Hence,density of the sediment,size of the sediment as well as velocity of the agent of erosion will often affect the rate deposition.
