Hello!
The best representation is "C. A cactus is moved from a sunny windowsill to a dark room..", because the cactus feed itself with photosyntesis.

Answer:
A) tortoiseshell female; black male
Explanation:
Females have two X chromosomes and males have an X and a Y chromosome.
<u>The possible genotypes and phenotypes are</u>:
- XᵒXᵒ: black female
- XᵒY: black male
- XᴼXᴼ: orange female
- XᴼY: orange male
- XᵒXᴼ: tortoiseshell female
<u>Cross of a black female and an orange male</u>
<h3>XᵒXᵒ x XᴼY</h3>
The female only produces Xᵒ gametes. The male produces Xᴼ and Y.
The possible offspring therefore is: XᵒXᴼ (tortoiseshell females) and XᵒY (black males). The answer is A.
No lesions in the mouth and throat
Weight increase of 1 lb over 3 days Correct
Temperature change from 100.2° F to 99.2° F
Capillary refill slowing from 2 seconds to 3 seconds
Weight increase of 1 lb (0.45 kg) over 3 days
Rationale: Vomiting results in fluid volume deficit. The most accurate method of evaluating fluid volume increase (the desired outcome) is weight. A temperature decrease is not reflective of fluid volume increase. Increasing capillary refill time is indicative of a fluid volume decrease, not an increase. The absence of mouth ulcers would allow the child to drink without pain but does not reflect a fluid volume increase.
Answer:
regulation of the diameter of blood vessels and control of blood pressure
Explanation:
Skeletal muscles are the multinucleated muscles with striations and are attached to the bones (skeleton). The main function of skeletal muscles is to generate the voluntary movement of the body or body parts. The skeletal muscles of face, rectum, and urinary bladder generate their voluntary movement as per the will of the organism. On the other hand, blood vessels are lined with smooth muscles with spindle-shaped cells.
For example, the muscles present in the subcutaneous layer of the skin of the face are responsible for various facial expressions. Contraction of these facial muscles brings about the movement of skin of the face to generate a wide variety of emotions. Smooth muscles of blood vessels are involuntary in nature.
Vasodilation and vasoconstriction as brought about by smooth muscles of blood vessels are regulated by the autonomic nervous system. Under the conditions of lower blood pressure, contraction of smooth muscles of blood vessels restore the reduced blood pressure. On the other hand, when the blood pressure rises above the normal range, the smooth muscles of blood vessels relax to dilate them and to lower down the blood pressure.
