Taste buds that are more sensitive to sweet flavors than to others are located
select one:
a. all over the tongue, as sensitivity to sweet is distributed throughout the tongue
b. on the tip of the tongue
c. on the back of the tongue
d. on the side of the tongue

b. On the tip of tongue.

Explanation:

The taste buds are present on the sensary organ that is tongue. On tongue taste receptor cells or taste buds in the form of papillae are present which detect different tastes. These receptors can detect taste stimuli like salty, sweet, bitter, sour and umami. Sweet is detected by the receptor cells or taste buds in the front of tongue. Sour and salty on the sides and in the back bitter taste can be detected.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
