Answer:
The heart is made up of heart muscle known as Cardiac muscle, or myocardium This contracts almost 70 times a minute and pumps about 5 liters of blood each minute.
Explanation:
The question is incomplete. Complete question is as followed :
Imagine a human disorder that is inherited as a dominant, X-linked trait. How would the frequency of this disorder vary between males and females?
A. Males would display this disorder with greater frequency than females.
B. Males and females would display this disorder with equal frequency.
C. Females would display this disorder with greater frequency than males.
Answer:
C. Females would display this disorder with greater frequency than males.
Explanation:
Most of the X-linked disorders are recessive. but if it is dominant, a dominant gene is carried on the X chromosome. So it will effect all the females being the dominant and doesnot effect males more than females.
Hence option C. Females would display this disorder with greater frequency than males is the right answer.
Answer:
Generalist
Explanation:
Living Organisms able to exists in different types of environment and have different types of food are called "Generalist"<u>Raccoons</u> are the best example of generalist. they are extended from North to Central America . they are able to survive even by consuming human garbage .It is this quality make them to thrive in different types of environment.
Answer:1) medulla to the diaphragm, increasing the rate of breathing
Explanation:
Basically involuntary respiration is controlled by the Respiration centers in the brain Stem. They are group of respiratory neurons ; the dorsal and ventral respiratory groups located in the medulla oblongata , and the pontine respiratory group located in the Pons varolii.
The primary function of this center is for creation and maintenance of respiration rhythms and adjustment of the sequences to fluctuation in body homeostatic balance .
In order to regulate respiration rate and its depth, it collects its input signals from chemoreceptors ( cells that generate biological signals from chemical substances), mechanoreceptors( receptors which relay external physical stimuli of touch, and pressure to internal stimulus by regulation of gated ion channels), the hypothalamus and the cerebral cortex. The fluctuation in the levels of plasma C02, oxygen, and blood pH, stimulated the input progression.
Therefore an elevated C02 blood levels, marked by low pH send input signals to the respiratory centers in the medulla.The latter sends signals to the respiratory muscles (and the diaphragm,) to initiate mechanism of rapid breathing to exhaled more C02 so that the acidity of the blood is reduced..
