Answer:
The field of evolutionary medicine uses evolutionary principles to understand changes in human anatomy and physiology that have occurred over time in response to environmental changes. Through this evolutionary-based approach, we can understand disease as a consequence of anatomical and physiological “trade-offs” that develop to facilitate survival and reproduction. We demonstrate how diachronic study of human anatomy and physiology is fundamental for an increased understanding of human health and disease.
Answer:
44
Explanation:
A somatic cell is diploid - it has 46 chromosomes. Half of these are from the mother, so there are 23 maternal chromosomes
A sex cell (gamete) is haploid - it has 23 chromosomes. There are (usually) two sex chromosomes in a diploid genome, either XX or XY, so there is one 1 in a haploid cell, giving a total of 22 autosomes
Barr bodies are inactive X chromosomes in a female somatic cell. This occurs to control dosage compensation (otherwise all the genes on the X in females would be expressed twice as much as they are in males). In a healthy female, there is normally one Barr body
A person with Kleinfelter's syndrome has two X chromosomes and one Y (XXY). They are biologically male, but have two X chromosomes. Therefore, one of these becomes a Barr body, as in females.
23 + 22 - 1 = 44
Answer:
CARBON IV OXIDE and WATER
Explanation:
When in the presence of oxygen, cells undergoes aerobic respiration which involves the breakdown of glucose into energy, water and carbon iv oxide. The carbon iv oxide and water are formed during citric acid cycle of respiration. The energy are absorbed and stored leaving water and carbon iv oxide. Carbon iv oxide is removed from the cells by diffusion into the bloodstream and removed by the lungs, converted into hydrocarnonate ions. Water is removed by diffusion from where it is removed by the kidneys as urine.

Answer:
The advantage and disadvantage of UV exposure is listed below
Explanation:
Advantage
Ultraviolet radiation is used as sterilizing agent before culturing a bacteria of fungi in an autoclave.
Disadvantage
Ultraviolet radiation exposure can cause DNA damage by the formation of cyclobutane ring between two adjacent thymine residues known as thymidine dimers along a DNA strand.
Ultraviotel exposure can cause skin cancer.
