The only disorder that cannot be represented using pedigree chart is sickle cell anemia. this because hemophilia, red-green color blindness, and duchenne muscular dystrophy are all X-linked traits. on the other hand sickle cell anemia is an autosomal recessive condition which cannot be represented in the pedigree chart since only sex linked traits are found this chart.
Because their bodies tell them that they need more oxygen and so breathe faster, and try and get the oxygen their body requires and depends on.
Answer:
I think the correct answer is D
The muscles that contract (during cold or fright), the slanted hair follicle is pulled upright, dimpling the skin surface with goosebumps are called arrector pili muscle.
The arrector pili muscle are tiny muscle that attaches to the base of the hair follicle at one end and to the dermal tissue on the other end. When the body feels cold or fright the body generate heat and the arrector pili muscle contract all at once, that causes goosebumps on the skin.
The arrector pili muscle acts as the thermoregulator. Straight stand hair increases air trapping, so that the heat loss from the body decreases. The arrector pili muscle are mediated by the sympathetic nervous system.

Answer:
advantages of sexual reproduction:
it produces variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual
advantages of asexual reproduction
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
Disadvantages of asexual reproduction
it does not lead to variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population
