Answer:
d)A...B...C
Explanation:
Hormones are chemical proteinous substances secreted in one location and transported to another location, in order to bring about a physiological effect. Hormones are secreted by endocrine glands which collectively makes up the endocrine system. Endocrine glands include testes, ovary, pancreas, thyroid, adrenal gland etc. A hormone is usually secreted when a change needs to be effected in a target cell.
What happens is that, when a particular physiological effect is needed by a target cell e.g growth, development, homeostasis, repair etc., it sends a negative feedback to the gland that is responsible for the secretion of the specific hormone. The particular endocrine gland, then, secretes the hormone into the bloodstream (ductless), which carries it for absorption by the target cell where it is needed.
Answer:
<em>By and large, volcanoes will in general get its energy from </em><em>radioactive decay in the Earth's</em><em> </em><em>inside</em><em>, which gives heat that turns out to be privately thought enough to create </em><em>halfway softening of Earth's shake. </em>
Explanation:
The inside of Earth is hot (the temperature of the centre arrives at in excess of 5,000 degrees Celsius) for two fundamental reasons: The heat from when the planet shaped, The heat from the decay of radioactive components.
Answer:
D. all options are correct
Explanation:
- There is a trade-off between the size of gametes and the number of gametes.
- The larger the gamete, the less mobile it is
- The probability that a zygote survives increases with its size, and the size of the zygote is a function of the sizes of the fusing gametes
12 is the total number of NADH FADH2 molecules that will be produced.
In each citric acid cycle, one molecule of FADH2 is formed during the conversion of succinic acid to fumaric.
The CAC is called a cycle because the starting molecule, oxaloacetate is regenerated at the end of the cycle.
It is also known as Krebs cycle. This is actually a part of a huge process called cellular respiration. The citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules.
NADH:- It is an energy shuttle that delivers high energy electrons to the electron transport chain where they eventually get to power the production of 2 to 3 ATP molecules.
FADH:- This is another energy shuttle that carries high energy electrons to the electron transport chain, where they will ultimately drive production of 1 to 2 ATP molecules.
