The hormone that's causing Marisol to overeat is INSULIN.
Marisol is suffering from diabetes. In diabetes the insulin production is very little or non existing. Since the insulin allows the glucose to enter the cells, and in diabetes this hormone practically doesn't exist, the glucose will accumulate in the blood, causing hyperglycemia, and she will be hungry because the cells don't have energy (glucose) entering.
Endocrine and circulatory (C) Endocrine system consists of glands and the hormones they secrete whist the circulatory system is the blood or as I like to call the “transport system” of the body.
Answer:
d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds
Explanation:
Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.
During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.
The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.
When the temperature reaches 0˚C (32˚F), the top layer of the lake freezes and turns into ice. In solid form, water molecules are less dense and thus ice floats on the top of the lake.
This solid barrier prevents any wind-induced mixing as well as protects the relatively warm water underneath. Furthermore, light is also blocked so that photosynthesis is inhibited during this period. As the lake water is separated from the atmosphere, no direct oxygen diffusion occurs.
All these factors together causes a more even distribution of nutrients and gases in a lake in winter.
