Answer;

Electron microscope

Explanation;

Electron microscopy (EM) has long been used in the discovery and description of viruses. Viruses have a size of roughly 1/100 of bacteria (or smaller), so they are too small to be seen in light microscopy.

Viruses are considerably smaller, as they are merely nucleic acid surrounded by a protein shell as opposed to an entire living cell. Viruses typically range from 20-400 nm, which means an electron microscope is needed to see them.

Question 1

MArishka [77]

Physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.

<h3>What do you mean by Physical changes?</h3>

Physical changes may be defined as those changes which appeared physically like color, odor, texture, mass, and density.

Chemical changes may lead to the formation of new chemicals with definite properties. It involves when the chemical identity of any substance may alter.

Therefore, physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.

Where would the leucine side chain most likely be found in a protein dissolved in water?

riadik2000 [5.3K]

Answer:

Burried in protein

Explanation:

Leucine have a branched hydrocarbon side chain. The side chain of leucine is nonpolar and hydrophobic.

If a protein have to face water, proteins fold in such a way during the tertiary structure that the amino acid with polar characteristics tend to remain on outer surface while amino acid with nonpolar characteristics tend to remain in the core of protein.

So Leucine side chain would be found burried in core of protein.

strojnjashka [21]

(1) All the genotypes are as follows: AABB, AaBB, AABb, AaBb, aaBB, aaBb, AAbb, Aabb, aabb.

(2) Assuming that Aa is dominant and Bb is recessive, there will be 9 phenotypes with both A and B allele dominant (i.e. AaBb, AABb); there will be 3 phenotypes with just the A allele dominant (i.e. Aabb, AAbb); there will be 3 phenotypes with just the B allele dominant (i.e. aaBb, aaBB); and there will be 1 phenotype with both alleles recessive (i.e. aabb). The phenotypic ratio in this case is 9:3:3:1.

(3) The probability of producing an offspring with the aabb genotype is 1/16 or 6%.
