The major reason older adults should monitor their intake of fluids is the ___________.
- A.
Older people suffer deceased levels of antidiuretic hormone
- B.
Older people do not exercise, so fluids do not move from compartment to compartment easily
- C.
Total body water decreases with age, and restoration of homeostasis is slower
- D.
Most older people do not eat the proper foods
Correct Answer
C. Total body water decreases with age, and restoration of homeostasis is slowerExplanation
As individuals age, their total body water decreases and the process of restoring homeostasis becomes slower. This means that older adults are at a higher risk of dehydration and fluid imbalance. Monitoring their intake of fluids becomes crucial to ensure that they are adequately hydrated and maintain proper bodily functions.Rate this question:

The female infant is born with several hundred oocytes, each on genetically unique. This is due to ____________.
- A.
Mutation
- B.
Recessive inheritance
- C.
Chromosome deletion
- D.
Independent associate and random crossover
Correct Answer
D. Independent associate and random crossoverExplanation
The female infant is born with several hundred oocytes, each one genetically unique, due to independent assortment and random crossover. During meiosis, the chromosomes in the oocytes undergo independent assortment, which means that they can line up in any combination during cell division. Additionally, there is a process called crossover where sections of chromosomes can exchange genetic material, further increasing genetic diversity. These two processes together result in each oocyte having a unique combination of genetic material, making them genetically distinct from one another.Rate this question:

Sex chromosomes of a normal male are ____________.
- A.
XX
- B.
YY
- C.
XY
- D.
Any of these, depending on the father.
Correct Answer
C. XYExplanation
The sex chromosomes of a normal male are XY. In humans, females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome determines the development of male reproductive organs and characteristics.Rate this question:

The diploid genome contains chromosomes from ________________.
- A.
The father only
- B.
The mother only
- C.
One parent, which synthesizes the other
- D.
Both the mother and the father
Correct Answer
D. Both the mother and the fatherExplanation
The diploid genome contains chromosomes from both the mother and the father. In sexual reproduction, each parent contributes one set of chromosomes to their offspring, resulting in a diploid genome with two sets of chromosomes. This ensures genetic diversity and allows for the combination of traits from both parents.Rate this question:
