A researcher claims that the Makira Island and the Santa Ana Island flycatchers are diverging into different species. Identify T

WO potential prezygotic barriers that may be contributing to the divergence and speciation of these two populations of birds. Identify ONE piece of evidence that would indicate that speciation has already occurred within the flycatcher populations.

Answer:

Prezygotic barriers:

1. Habitat isolation

2. Behavioral isolation

Explanation:

Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.

The two mechanisms of the pre-zygotic barriers are the:

1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.

2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.

Thus, Habitat isolation and Behavioral isolation are correct.

A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr
Mariulka [41]
The correct answer is 50%, or 1/2. We know that round seeds are dominant, since the round pea plant has a genotype of Rr and the wrinkled pea plant has a genotype of rr. If it helps, draw a Punnett square with the two genotypes.

   R  r
r
r

The square works exactly like a coordinate grid. Combine the letters above and beside whichever of the four spaces you chose to find the genotype for that space.

   R  r
r Rr  rr
r Rr  rr

Therefore, 2 out of 4 of the pea plants have round seeds, since a genotype of Rr means that a plant will have round seeds, and 2 out of 4 will have wrinkled seeds, since a genotype of rr means that a plant will have wrinkled seeds. 2/4 simplifies to 1/2, or 50%. Therefore, there is a 50% chance that the offspring will have wrinkled seeds.

Hope this helps!

Which statements did stacey use to conclude that she was looking at a plant cell?
nydimaria [60]
Answer: <span>
The cell has the shape of a rectangle.
What appears to be a large space can be seen inside the cell
</span><span>Increasing the light source reveals green dots inside the cell.

The only  cell that has a rectangular shape is a plant cell duo to the cell wall.
The large spaces inside the cell are the vacuoles.
The green dots are chloroplasts.

How do microscopes differ in magnification and resolution?
Verizon [17]

1.Magnification is the ability of optical instruments, such as a telescope or a microscope, to make an object bigger while resolution is the ability of optical instruments to produce images that are clearer, finer, and sharper.

2.Resolution is the power of an optical instrument to capture and produce more details of an image while magnification is the power of an instrument to create and produce a much larger image of an object.

3.Resolution can be expressed in arcsec or seconds while magnification can be expressed by a whole number and the letter “X.”

4.Although both are dependent upon each other, a high magnification does not always guarantee a high resolution.

5.Magnification allows us to see small objects, especially those that are not visible to the naked eye, while resolution allows us to see these objects more clearly and with more details.
