he correct answer is number one. A chromosome is composed of many genes. A chromosome is referred to as a DNA molecule in an organism's body, which consists of genetic materials. Chromosomes consists of numerous genes within them, in their nucleus and mitochondria, genes are found inside the Chromosomes itself
Answer:
here.
Explanation:
The genes coding for colour show codominance. Both the brown and white pigment are equally expressed in the phenotype to give the tan colour.
Considering that the allele for brown pigment is CB and that for white pigment is CW, the genotype for the brown bird is CB CB and that for the white bird is CW CW.
Crossing CB CB × CW CW,
100% CB CW - tan-coloured birds
This phenomenon is called Eclipse.
All of the following contributes to turbulent blood flow except third and fourth heart sounds.
<h3><u>
Explanation:</u></h3>
The blood flow in human body is always described to be laminar. Some conditions cause the high flow when there is an ascending aorta. This causes the laminar flow of blood into turbulent. When this occurs the flow of the blood will not be smooth and linear.
When the kinetic energy in the fluid flow increases the turbulent flow of blood occurs. Both the magnitude and the direction of the flow changes in this type of blood flow. These are caused by the irregularities in the vessel walls, flow rates to ne higher and opening of the valves of the heart.
