Answer:
Of all the energy that does reach Earth, slightly less than 34 percent is reflected back to space by clouds. The Earth itself reflects another 66 percent back to space. Less than one percent of the total energy that reaches Earth is used by plants for photosynthesis.
Explanation:
Answer: is seen below
Explanation:
Termination will not take place if the strings of A nucleotides following an inverted repeat of rho- independent termination ( which forms an hairpin structure)were deleted. Although, RNA polymerase may pause briefly at the hairpin, the presence of A- U base pairs is needed to destabilize the DNA - RNA interaction and to end transcription. If the string A nucleotides is not present, then transcription of RNA polymerase will continue.
Answer:
Hypothalamic-pituitary-adrenal axis (HPA axis)
Explanation:
- The three-stage process describing the physiological changes that take place in the body when it is under stress is known as general adaptation syndrome (GAS).
- The model describing the three-stage process was given by the scientist Hans Selye.
- According to this model, the responses in the body that occur during stress is regulated by the Hypothalamic-pituitary-adrenal axis (HPA axis) where the brain senses the stress and then the signals travel from the hypothalamus to the pituitary and finally the body releases cortisol from adrenal glands that contributes to the various changes.
