Answer:
A. Smell
Explanation:
Mechanoreceptors are known to primary sensory structures. Their function is to provide information about the mechanical characteristics of the internal and external environments. These mechanoreceptors usually detect stimuli such as pressure, vibration, sound and touch from the internal and external environments.
Smell does not rely on mechanoreceptors but rather rely on olfactory receptors.
Answer:Animal cells but some plant cells also have it.
Explanation:
Answer:
the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system
Explanation:
The human respiratory system is responsible for taking in oxygen-rich air, and they expelling oxygen-poor air. The respiratory system consists of lungs, which helps in the exchange of gases: Oxygen and carbon dioxide.
The statement ''the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system'' explains the change in oxygen concentration of the inspired air

Since the recessive allele is on the X chromosome, in order for a woman to have this condition, both copies of her X chromosome has to have the recessive allele. One copy of the allele would have to come from her mother, and the second copy from her father. The copy from her mother is a 50/50 chance if her mother was heterozygous with one copy of the recessive allele and one copy of a normal allele and therefore didn't exhibit the dystrophy and therefore didn't know she was a carrier. But the father only has 1 copy of the allele and therefore would exhibit the dystrophy and as such would be unlikely to have engaged in procreative sex that would pass on the defective allele to his offspring. This is especially true since duchenne muscular dystrophy will typically start to manifest itself in male children around starting around age 4.</span>
