Cleavage lacks the growth phase of mitosis resulting in progressively smaller cells
Hi there! The answer should be B. Chloroplasts contain chlorophyll which allows the plant to undergo photosynthesis, and this allows the plant to make its own food. Hope this helps you!

Complete question:
A sample of butterflies contained 50% yellow-winged individuals and 50% black-winged individuals. In this species, wing color is determined by a single gene with two alleles, and the allele for black is dominant. Which of the following statements about the allele frequencies in the sample would most likely be true? Do not assume that this sample was obtained from a population in genetic equilibrium.
a)The frequency of the yellow allele is greater than that of the black allele.
b)The allele frequency of yellow is 3 times the allele frequency of black.
c)The allele frequency of yellow is twice the allele frequency of black.
d)The allele frequencies of black and yellow are equal.
e) The allele frequency of black is greater than the allele frequency of yellow.
2.Now assume that the population of butterflies sampled in question above is in Hardy-Weinberg equilibrium. Also assume that the sample is random and large enough that the allele frequencies in the sample equal the allele frequencies in the population. What is the frequency of the allele for a) yellow wings in the population? Assuming Hardy-Weinberg equilibrium in question 1, what would the correct answer be and why?
Answer:
- a)The frequency of the yellow allele is greater than that of the black allele.
- f(b) = q = 0.71

Answer:
<u>Light microscope</u>:
- use a beam of light to produce magnified images
- can be used to examine living cells and tissues
<u>Scanning electron microscope</u>:
- use a beam of electrons to produce magnified images
- can be used to examine DNA
- can be used to examine cells
<u>Transmission electron microscope</u>:
- use a beam of electrons to produce magnified images
- can be used to examine DNA
- can be used to examine cells
Explanation:
Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.
Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:
- <u>Scanning electron microscope(SEM): </u>an electron beam passes over the specimen's surface and displaces electrons which are then focused on a screen to form an image. Images appear in 3-D
- <u>Transmission electron microscope: </u>electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D
