<span>The correct
answer is c. hypothalamus to pituitary gland to adrenal glands.

When
it comes to stress, hypothalamus-pituitary-adrenal axis (HPA) is responsible for
stress response. Hypothalamus releases corticotropin-releasing hormone (CRH)
which binds to its receptors on the anterior pituitary gland. As a result, adrenocorticotropic hormone (ACTH) is released and it stimulates the release of
cortisol from the adrenal gland. At a certain levels of cortisol, this steroid
hormone exerts negative feedback to the hypothalamic release of CRH.
Explanation:
Invading infectious diseases can, in theory, lead to the extinction of host populations, particularly if reservoir species are present or if disease transmission is frequency-dependent.
Answer:
C. Electrons are released into the electron transport system.
Explanation:
Photosynthesis has both light dependent processes and light-independent processes. In the light-dependent reactions, photosystem II is the first protein complex. Photosystem II is present in the thylakoid membrane of plants.
<em>When the photons or light energy hits photosystem II, the free electron excites and released into the electron transport system (series of proteins). </em>The electron then passes through electron transport system and the energy from the electron fuels the hydrogen ions to move against their concentration gradient. Once the energy is utilized, the electron is accepted by photosystem I.
Hence, the correct option is C.
Answer:
"The latitude of a region determines how much sunlight the area receives" this statement says about why the latitude of a region influences its climate.
Explanation:
The latitude determines the sunlight of the area receives because, the more the latitude the sharper will be angle of the sun's rays which will reach the surface. Means that the rays of the sun are being spread over the broader area. Hence, More the latitude receive will be the less than the lower latitude areas located nearer to the equator. As, we know the sun's ray first strikes over the Earth's surface which is near the equator as these places receive direct solar radiation. At greater latitude the solar radiations gets spread in more area and hence the temperature also reduces.
Is this multiple choice?!
