When you are cold, your muscles begin to contract involuntarily and cause you to shiver. why do you think this occurs? how does
DanielleElmas [232]
Shivering occurs when the core temperature of the body begins to decrease which would threaten normal body function. Shivering is a response by the body to bring back temperature back to homeostasis. Trembling is the continual involuntary contraction of muscles. Muscle activity releases heat that warms up the body. This is the reason why we sweat during physical activities as the body sheds excess heat generated by the muscles in order to maintain the homeostatic body temperatures of 37 degrees centigrade.

Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human X chromosome. The patient
klio [65]

Answer:

One-half of the daughters of an affected man would have this condition.

Explanation:

Each daughter born to a woman that is positive for a dystrophin mutation on one of her two X chromosomes possess a 50 percent likelihood of possessing the mutation and also becoming a carrier. Carriers at times do not show the disease symptoms but may give birth to a child that has the mutation or the disease condition. DMD carriers do have a higher chance of cardiomyopathy.

A man with DMD cannot transfer the affected gene to his sons since he passes to his son a Y chromosome, not the X chromosome. But he will definately transfer it to his daughters, since each daughter possess her father’s only X chromosome resulting in the daughters being carriers.

Hence, One-half of the daughters of an affected father and a carrier mother could have this condition.
