The given question is incomplete. The complete question is:
In humans, the maintenance of a stable internal temperature is a direct result of___________.
a. detection of and reaction to stimuli in the environment
b. digestion of starches and absorption of protein from the internal environment
c. diffusion of water and excretion of glucose to the external environment
d. transport of ATP and locomotion through the environment
Answer:
a. detection of and reaction to stimuli in the environment
Explanation:
Thermoreceptors present in skin layers of the human body sense the deviation of the body temperature from the normal range. As the body temperature rises above normal, the thermoreceptors send signals to the brain which n turn signals dermal blood vessels to dilate and sweat glands to secrete sweat. The heat from the body surface is lost to the surroundings to drop the body temperature towards the normal range.
On the other hand, when the body temperature goes below the normal range, thermoreceptors send signals to the brain which in turn signals dermal blood vessels to constrict to conserve the body heat. If body temperature continues to drop, muscles are signaled to contract involuntarily to generate body heat to raise the body temperature towards the normal range.
Answer:
Three major classes of RNA found in the cell are:
Explanation:
- Messenger RNA: function is to carry the genetic code from the nucleus to the cytoplasm.
- Ribosomal RNA: is present in the cytoplasm of the cell. ribosomal RNA plays a major role in the synthesis of protein.
- Transfer RNA: is present in cellular cytoplasm, the function of tRNA is to transfer the amino acids to the ribosome.
It is not involved with the production of any specific type of lymphocyte.
Answer: Option A) emulsification of lipids
Explanation:
Since the gall bladder has the sole responsibility storing bile produced by the liver, which is necessary for the digestion and absorption of lipids in the duodenum, its absence would hinder lipids breakdown, and might results in health risks
In the given food web, the role of fungus is - to remove dead organisms.
In any ecosystem, the fungus plays the role of decomposers means they break down dead organic matter and return vital nutrients to the soil.
