12/44 = 0.2727
(X100)
= 27
( therefore the percent mass of carbon in carbon dioxide is 27%)

Answer:
Sugars
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct
Explanation:
Answer:
B. oxygen and carbon dioxide.
Explanation:
During cellular respiration, organisms uses oxygen for breakdown of food molecules such glucose and carbondioxide gas is released in the atmosphere. Respiration is a process in which energy is produced in the form of Adenine tri phosphate (ATP) and releases carbondioxide by the chemical combination of glucose and oxygen molecules. The type of respiration in which oxygen is used is known as aerobic respiration.
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.
