Which of the following is the best theme statement

faust18 [17]

Answer:

The electron microscope

Explanation:

The microscope that would be best suited to study the inner structure of the chloroplast would be the electron microscope.

The electron microscope has a high magnifying property due to the fact that it uses a beam of accelerated electrons as a source of illumination, unlike the light microscope that uses visible light. While the light microscope might be enough to see the inner portion and the organelles of the cell, the tiny nature of the inner structure of the chloroplast means that the light microscope will not be able to view the details. A more powerful microscope like the electron microscope would be required.

The cerebellum also assists people with eye movement and vision. Problems with the cerebellum are rare and mostly involve movement .

Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is presen

Nina [5.8K]

Explanation:

As you can see in the picture below, this is a dihybrid cross with a twist.

We can accomplish that mutually parentages are heterozygotes for both characters because the genotypes are

9 unicorns with curly tails (shown in green)

3 with straight tails (shown in red)

3 curly tales trait carriers with no tail (shown in dark blue)

1 straight tail trait carriers with no tail ( shown in light blue)

If this was an ordinary case of the dihybrid cross, we would get a 9:3:3:1 phenotype ratio.

However, since the first trait, the presence of the tail, is affecting the other trait, the trait texture, the ratio is altered.

$\frac{1}{4}$ of the offspring (genotypes tt C_ and tt SS) has no tail, therefore we cannot observe the texture of the tail (some of the tailless individuals have Curly alleles -blue squares marked with green, some of them have Straight alleles -blue square marked with red ).

Therefore, the altered ratio is $\frac{1}{2}$ curly tails, $\frac{1}{4}$ straight tales, $\frac{1}{4}$ tailless

A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or short (k) stem. A scientist is preparing a Punne

andrew11 [14]

Answer: A. gk, gK

The scientist doing a dihybrid crossing using plants with a genotype ggKk. To make the Punnet square, you need to understand how the gamete divided. The square should be
K k
g gK gk
g gK gk

The possible gamete for gg-Kk would be
1. gK
2. gk

What safety procedural step must always be performed when setting up a vacuum filtration apparatus?

Likurg_2 [28]

The safety procedural step that must always be performed when setting up a vacuum filtration apparatus is that first, you should always wear the proper protective equipment, next is that the vacuum filtration—you should clamp the flask of which is needed, securely to the ring stand. It must be secure or it may be in the way of performing the experiment.
