Answer:

Third degree burn

Explanation:

Primarily there are three degrees of burns first, second and third. The first degree of burn is least severe and the third degree of burn is most severe.

During first degree of burn, only epidermis get affected. The site of burn becomes red, dry and painful but no blisters are formed. In the second degree of burn epidermis and some part of dermis gets is damages and blisters are formed.

In third-degree burn epidermis and dermis gets destroyed and the burn encompasses the dermis and damaged tendons and muscles. The area that burned become white and charred and due damage in nerve endings sensation is not present in that region. So the correct answer is third-degree burn.

lara31 [8.8K]

Answer:

<h2>A) Yes, 12 mu</h2><h2>B) AaWw</h2><h2>C) 0.25%</h2><h2 />

Explanation:

As given,

Allele A for  blue anthocynin.

aa for yellow kernel;

at  second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are:  AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

a)

Recombinant progeny are  169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with  aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

What are the 2 ways that you can do to enhance the<br> resolvingpower on the microscope?
satela [25.4K]

Answer:

Explanation:

The resolving power of the microscope is dependent upon the objective lens. It can be measured by the ability of the lens to differentiate between the two lines or points on the specimen under observation. The more the resolving power the smaller will be the distance between the two lines or points that can be distinguished.

The following are the two ways that can be used to enhance the resolving power on the microscope:

Using a lens that has a higher aperture.

Decreasing the amount of light being entered into the microscope that means using light of less wavelength.

Which of the following does natural selection act directly upon? Alleles, genes, individual organisms, or mutations?
Inga [223]

Natural selection act directly upon <u>Alleles</u>

Explanation:

Genes, such as that of fur color, have many variants called alleles. Natural selection act on the alleles and chooses the best fit for an environment and eliminates the disadvantageous ones from the population over generations. Mutations are a rare occurrence that increases the number of allelic variants of a genes on which natural selection can act upon.

A Chlorella cell viewed through a microscope is 0.00005 m wide when the magnification is 2000.
juin [17]

Answer:

0.0025micrometer.

Explanation:

To calculate the actual size of the image, the formula to be used is

Actual size=Image size÷magnification.

The image size is 0.00005 wide

Magnification is 2000

First, convert the image size to micrometer.

=0.00005 × 1000000

50micrometers.

Actual size= 50÷2000

Actual size = 0.0025
