Diffusion is important to organisms because it is the process by which useful molecules enter the body cellsand waste products are removed. Digested food molecules (amino acids, glucose) move down a concentration gradient from the intestine to the blood.
Answer:
The second pair of grandparents have approximately 12 to 19 boys as grandchildren.
Explanation:
The probability of a grandchild being a girl or a boy is same, i.e., 
.
The first pair of grandparents have 4 grandchildren.
The second pair of grandparents have 32 grandchildren.
If first pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,
Thus, the first pair of grandparents have approximately 2 to 3 boys as grandchildren.
If second pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,
Thus, the second pair of grandparents have approximately 12 to 19 boys as grandchildren.
So, it is clear that the second pair of grandparents are more likely to have between 40% and 60% boys as grandchildren.
Also according to the law of large numbers as the sample size increases the probability of an event gets closer to the theoretical probability.
The sperm will be immature and sperm count will be lower if the bulbourethral gland in males fails to perform its function
The bulbourethral gland or Cowper's gland, which is homologous to the Bartholin's gland in females, produces pre-ejaculate that cleanses and lubricates the urethra prior to the arrival of the semen.
The Cowper's glands or bulbourethral glands produce the first fluid that leaves the urethra in order to neutralize the acid left from the urine. The sperm like a basic or alkaline environment in order to survive. If the function of the Cowper's glands or bulbourethral glands fails to perform its function then the sperm will not get a proper medium to travel and will get diminished in the urethra and the sperm count will get reduced.
