Answer:
Robertsonian translocation.
Explanation:
the disorder created as a result of the final chromosomal change that is shown is Robertsonian translocation. Translocation is one of the mutation that happens in chromosomes.
Answer:
pressure changes of alternating contraction and relaxation during the cardiac cycle.
Explanation:
Opening and closing of heart valves are regulated by changes in the blood pressure of various heart chambers during the cardiac cycle. During atrial systole, the higher blood pressure in the atria opens both AV valves and forces the blood to enter the ventricles. The semilunar valves are closed. During ventricular systole, the higher blood pressure in the ventricles opens both semilunar valves to allow the blood to enter the pulmonary trunk and aorta. At this time, both the atrioventricular valves are closed.
Answer:
They are solid at room temperature. They include a carbon single bond.
Explanation:
Look at this image- hope it helps. Because of the fact that they are not bent, they are packed tightly and solid, not liquid.
Answer:
True
Explanation:
Meiosis can be described as a type of cell division in which four daughter cells are produced. The number of chromosomes in each of the daughter cells formed is half the number of chromosomes of the parent.
During this type of cell division, the processes of homologous recombination and crossing over occur. During crossing over, segments of DNA are exchanged between the homologous chromosomes due to which genetic diversity occurs.
