When you're still breathing hard after you finish exercising, it's called . when you can't breathe in fast enough to get all the oxygen your muscles need, it's called . when you're breathing in all the oxygen your muscles need, it's called . what is it that produces lactic acid? no lactic acid is being produced or removed during . extra oxygen that get rid of the lactic acid is called ?

When one still breathes hard even after finishing the exercise is known as EPOC or extra post-exercise oxygen consumption.  

Oxygen deficit refers to the condition when one cannot breathe in fast enough to get all the oxygen required by the body.  

Steady-state refers to the state when the body receives the amount of oxygen required by the tissues of the body in order to generate adequate amount of energy.  

In the state of oxygen deficit, the production of lactic acid takes place.  

At the time of steady-state, no lactic acid gets produced or removed.  

During EPOC, extra oxygen assists in getting rid of the lactic acid produced.  

answer: c

explanation:

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.
