Answer:
Obligate anaerobes. (Ans. D)
Explanation:
Anaerobes: They are micro-organisms that do not require energy oxygen for metabolism. They can only survive in an environment that lacks oxygen.
Obligate anaerobes are bacteria typically living in various places naturally. Many of obligate anaerobes living in the human body, in places such as the mouth and gastrointestinal tract (most of the obligate anaerobes present their) where oxygen level present in very low concentration.
Obligate anaerobes do not contain several enzymes needed to detoxifying oxygen present in the cell. Oxygen produces several byproducts in the presence of water such as hydrogen peroxide, it is a week acid and affects no. of enzymes present in anaerobic cells. In a high level of oxygen anaerobic cells become more acidic and not able to function.
So that's why they are found in no oxygen or low oxygen environment like the gastrointestinal tract.
Carbohydrates are the main energy source. But lipids are used for storing energy so
Answer:
Since sexual reproduction requires two individuals, it allows intermingling of genes which is beneficial for the individuals as well as the entire species. The organisms produced by asexual reproduction are genetically identical to each other. ( I hope it helps )
A product of the anterior pituitary gland that causes color changes in it's target cells is melanocyte stimulating hormone (MSH) .
Hence the correct answer is option D .
<h3>
What is the pituitary gland ? </h3>
Pituitary is known as the master gland of our body, because it controls and coordinates the development and functions of other endocrine glands. It is found in the base of the brain in a bony cavity called 'sella tursica' and is attached to the hypothalamus.
It has two parts - anterior pituitary ( also known as adenohypophysis) and posterior pituitary ( neurohypophysis).
<h3>
What is anterior pituitary?</h3>
The anterior pituitary has two parts para distalis and pars intermedia. Of this , FSH, LH, TSH, ACTH etc., is released by pars distalis, and the only hormone from pars intermedia is the MSH .
- FSH - Follicle Stimulating Hormone - Stimulates the growth of ovarian follicles for next menstrual cycle.
- LH - Luteinizing Hormone - Induces ovulation of fully mature follicles and maintains corpus luteum.
- TSH - Thyroid Stimulating Hormone - Stimulates secretions of Thyroid gland.
- MSH - Melanocyte stimulating hormone - acts on melanocytes ( cells with melanin, a pigment ) and regulates the pigmentation of the skin.
Hence from the above points ,we can conclude that MSH causes color changes in it's target cells.
So correct answer is option D .

Answer:
B
Explanation:
Wall cell has to be strong to bring protection to the cell. In general it is made of beta-glycosidic bonds.
Storage polysaccharides, are a source of available energy for the cell in any moment. Therefore, the bonds of storage polysaccharides need to be weak. In that way, when the cell needs energy from carbohydrates, it is not going to spend so much energy trying to break the bond.
