Explanation:

They are useful as they can predict the genetic probability of a particular phenotype arising in a couple's offspring. In other words, it can tell you if you will or will not have a certain trait.

Alisiya [41]
An animal cell that is placed in a hypotonic solution will rapidly gain water, because osmosis would cause the water to move to an area with more solutes. In this case, that is the inside of the cell. A cell in a hypotonic solution may gain enough water to lyse, or rupture, the cell membrane, which destroys the cell.

What is the purpose of Transcription?
Vlad [161]

Answer:

The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.

Which component of the electrocardiogram represents the duration of ventricular contraction?
Advocard [28]

QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).

Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.

P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.

Hm, raw materials: three stages exist in the electron transport:  It is, glycolysis, citric acid cycle, and electron transport.

In animals, like humans, waste products of aerobic respiration is, water and carbon dioxide, and waste product of anaerobic respiration are lacic acid.

Each of two parents has the genotype green divided by brown​, which consists of the pair of alleles that determine eye color​, a
Liula [17]

Answer:

A)BB-Bg-Bg-GG

B)The probability is 25%

C)The probability is 75%

Explanation:

In order to solve this you just have to create a punnet square, where the parents are shown to both have brown and green coloured eyes genes, so it would be like this:

               Mother:      Brown                                 Green

Father↓  

Brown                      Brown-Brown                 Brown-Green

Green                      Brown-Green                  Green-Green

As the instructions say that if any kid had one green allele that would be the dominant, only the Brown-Brown will show the fenotype, so there´s 1/4 chance to happen, or 25%, the other probability of having green eyes is 3/4 or 75%
