OverLord2011 [107]

Genotype: 50% Aa and 50% aa

Phenotype: 50% Dimples and 50% no dimples

Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.

Hope this helps!

muminat

Answer:

Impact.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

In Science, the study of blood is generally referred to as serology.

Impact refers to how fast blood traveled from its source to where it landed.

This ultimately implies that, an impact is a measure of the rate at which blood travels from its source to where it lands. The four (4) phases of impact includes;

I. Displacement.

II. Retraction.

III. Contact and collapse.

IV. Dispersion.

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

Generally, the right atrioventricular valve (AV) is also referred to as the tricuspid valve and is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
