Answer:
The deoxygenated blood enters the heart from the superior and inferior vena cava and pumped into the right atria then pushed down into the right ventricle from there the blood is pumped out through the pulmonary artery (the only place in the body where an artery has deoxygenated blood) to the lungs. The blood gets oxygenated and returns to the heart via the pulmonary vein (the only place in the body where a vein carries oxygenated blood) and pushed into the left atria the pumped into the left ventricle and out to the body via the aorta.
Explanation:
Answer:
Explanation:
Given:
Represent
- Susan's velocity with 
- Michael's velocity with 
eastwards
westwards
Required
Determine how fast is relative to
From the question, one train moves eastwards while the other moves westwards.
This means that travel in opposite travel and the relative speed (V) is calculated as:
Substitute values for and
<em>Hence, the Susan's train is moving 2m/s in relative to Michael's train</em>
The type of mutation which is observed here is substitution mutation. According to the fact that sickle cell anaemia is occuring at the at beta-globin gene, the correct answer is c.substitution mutation as it shows mutation point as <span>a single base. Hope it will help! Regards.</span>
Answer:
b 40-60 days
Explanation:
Incubation takes about 60 days, but since the temperature of the sand governs the speed at which the embryos develop, the hatching period can cover a broad range.
