Answer:

Plate boundaries are important because they are often associated with earthquakes and volcanoes. When Earth's tectonic plates grind past one another, enormous amounts of energy can be released in the form of earthquakes.

Protein Omicron contains 4 subunits. Two subunits are 65 kDa in size and are held together by a disulfide bond. One subunit is 8

Volgvan

Answer:

The correct answer is - 130 kDa, 82 kDa, 45 KDa.

Explanation:

In the question given is there are 4 subunits in protein omicron in which two subunits are - 65 kDa and the other two subunits are - 85 kDa and 45 kDa.

So the size band would be in absence of beta-mercaptoethanol which is very essential to break down disulfide bonds that held together these subunits:

Size band = 65 KDa + 65 KDa

= 130 KDa (one band) ( 65+65=130),

82, 45 as without beta mercaptoethanol disulfide bond is not broken .

Thus, the correct answer is - 130 kDa, 82 kDa, 45 KDa.

In pea plants, the gene for the color of the seed has two alleles. In the following Punnett square shown below, the dominant all

Bogdan [553]

<h2>Question 1.</h2><h2>Answer:</h2>

The correct answer is option D which is 100%.

<h3>Explanation:</h3>

According to the description of Punnett square given in the question, there will be there will be two types of genotype and one type of phenotype which is yellow.

YY, homozygous dominant = Yellow Seeds.
Yy, heterozygous = Yellow Seeds
So the progeny will be 100% of yellow seeds.

Punnett square is also attached.

<h2>Question No.2.</h2><h2>Answer:</h2>

The correct answer is the option A which predicts the genotypic and phenotypic probabilities of possible.

<h3>Explanation:</h3>

<u><em>Punnett square is a way to determine the probable genotype of expected offspring by the genotypes of father and mother devised by Punnett.</em></u>

In this method, A square shaped table is constructed and the alleles of the gene of father/male are written on the top of tables, on the column.
The alleles of the mother are written in horizontal to square, in front of rows.
So the genotypes in the square box by multiplying row and column alleles will be expected genotype of an offspring.
The example is attached below.

<h2>Question no. 3.</h2><h2>Answer:</h2>

The correct answer is option C which is 1 = TT; 2 = Tt; 3 = Tt; 4 = tt .

<h3>Explanation:</h3>

The Punnett square is made by the description given in the question.

There are total 4 boxes. In box number 1 which is on top left genotype is TT and in box 2 which is on top right genotype is Tt. In box 3, the genotype is Tt and in box 4, the genotype is tt.

So according to the given Punnett square information in option C is correct one.

How do new cells form in plants and animals?

frozen [14]

In both animals and plants, cells produce new cells by mitosis - but they split differently. A cleavage farrow forms in the animal cell and it splits. For the plant cell, a cell plate forms and then the cell splits.
