Correct question:
The hypothalamus __________.
a) influences the function of only one lobe of the pituitary gland.
b) synthesizes all of the hormones produced by the pituitary gland.
c) regulates both reproduction and body temperature.
d) produces only inhibitory hormones.
Answer:
C) Regulates both reproduction and body temperature.
Explanation:
The hypothalamus is a small but important area in the center of the brain. It plays an important role in hormone production and helps to stimulate many important processes in the body and is located in the brain, between the pituitary gland and thalamus.
The hypothalamus’ main role is to keep the body in homeostasis as much as possible.
Homeostasis means a healthful, balanced bodily state.
The hypothalamus acts as the link between the endocrine and nervous systems to achieve this. It plays a part in many essential functions of the body such as: body temperature, thirst, appetite and weight control, emotions, sex drive, blood pressure and heart rate, production of digestive juices and balancing bodily fluids.
DNA is composed of nucleotides, which are composed of three parts:
1. A five carbon carbohydrate (pentose)
Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by
. They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)
2. A nitrogenous base
Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines
The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.
The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.
3. One or more phosphate groups
A phosphate consists of a trivalent anion that contains one phosphorus atom and four oxygen atoms. Its molecular formula is expressed by
.
Answer:
intrinsic
Explanation:
Proteins are dynamic molecules that are capable of INTRINSIC motion that can have important functional relevance. The existence of this type of motion has suggested that enzymes are capable - even in the absence of substrate - of many of the same movements that can be detected during their catalytic cycle
