Which of the following is a function of the cell membrane?

Answer:

B

Explanation:

Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning "two".

The word "di" means two, and "diatomic" means a molecule with two atoms that is present in Option B. Diatomic molecule may consist of similar atoms or may have different atoms, such as nitrogen oxide.

Diatomic molecules are those that have two atoms within the molecule, such as hydrogen (H₂), nitrogen oxide, etc. In a single compound, there are many atoms that are present, and they make different bonds with each other, such as the covalent bond.

Aside from the covalent bond, there are other types of bonds, such as ionic bonds, but not all types of elements that are present in the periodic table can form the diatomic molecule. The homonuclear diatomic molecule is hydrogen, where two hydrogen atoms are present, and an example of the heteronuclear diatomic molecule is nitrogen oxide, where nitrogen and oxygen atoms are present.

Hence, the correct answer is option B, which is a diatomic molecule with two atoms.

Answer:

[D]. None of the above

Explanation:

Epithelium are one of the type of four tissues found in living systems. They possess a variety of functions and are found to line/cover the surfaces of most organs. Epithelial tissues are classified based on the number of cell layers (simple and stratified) and shape (squamous, columnar, and cuboidal).

Based on their shape;

- Squamous epithelium are made up of scale-like flat cells that line the surfaces of alveoli of the lungs etc. They are of thin, flat, irregular shaped cells which fit together like floor tiles to form a compact tissue as stated in this question.

- Cuboidal epithelium contains cells whose shape are similar to that of a cuboid i.e. close width and height. They are located in the kidney tubules, thyroid vesicles and in glands like pancreas.

- Columnar epithelium are relatively thin and elongated in shape, hence, they are found in organs and surfaces whose function mainly is absorption and secretion.

Hence, NONE of the mentioned statements are UNTRUE

positive feedback mechanism increased the release of oxytocin to promote further contractions

Explanation:

Padma is having a baby. The best description of how her body will keep her in the homeostasis is a positive feedback mechanism increases the release of oxytocin to promote further contractions. Thus, the correct option is A.

Oxytocin is a natural hormone which manages the key aspects of the female and male reproductive systems in humans, including the labor, delivery, and lactation in females, as well as other aspects of the human behavior.

Oxytocin can induce the anti-stress-like effects such as reduction of the blood pressure and cortisol levels in humans. Oxytocin increases pain thresholds, exerts an anxiolytic-like effect and also stimulates various types of positive social interactions in individuals. In addition, it is also responsible for promoting growth and healing process.

Therefore, the correct option is A.

Osmosis and diffusion are two types of passive transport.

Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics.

The answer is "runoff from fertilizer".

Explanation:

The fertilizer is any natural or synthetic material, which is applied with soil or tissue of plant species and provides one or more plant foods, which are necessary for plant growth.  

Due to the high durability and excessive irrigation use, nitrate fertilizers, which provide high solubility, as well as the nitrate ion throughout the finishes the product and readily drained away, that's why the given choice is correct.

d. Long periods of stability were punctuated with periods of evolutionary change.

Explanation:

Gould and Eldridge inferred that evolution occurred because of the sudden existence of new factors that force a certain type of species to adapt to the new situation. (Things such as sudden change in the environment, sudden change of the species' genetic composition that passed over during natural selection ,etc)

They believe this is why periods of evolutionary change happened in considerably shorter period of time right in the middle of periods of stability.

In "1984" by george orwell, the dystopian society he has created horrfies me. The idea that even your thoughts are monitered disrupts your self expression and how you interact with the world. To live in a world where you cannot do anything but basic busy work seems tactful. I bvelieve people should be happy and never fear a hugher authority or a "system".

Explanation:

Transfer RNA acts as a link (also called an adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that comprise a protein. Therefore, option (C) is correct.

Transfer RNA is an adapter molecule that is made of RNA and normally ranges in length from 76 to 90 nucleotides. Its primary function is to act as the physical link between the amino acid sequence of proteins and the mRNA that encodes them. Transfer RNA achieves this goal by transporting an amino acid to the ribosome, which is the component of a cell that is responsible for the synthesis of proteins.

The tRNA molecule is characterized by its characteristic folded structure, which consists of three hairpin loops that are arranged in the manner of a clover with three leaves. A sequence known as the anticodon is contained within one of these hairpin loops. This anticodon has the ability to detect and decode mRNA codons. Each transfer RNA (tRNA) has the amino acid that corresponds to it connected to the very end of it.

There are two reasons for this. The first reason is that the distance between the two strands of DNA is constant. Two purines together would be too big to fit in that distance, and two pyrimidines together would be too small.
