Answer:

Biological Species concept

Explanation:

Biological Species concept is known as the idea that species are defined based on the ability to interbreed with each other and exchange genes.

This is because interbreeding enables exchange and preservation of the genes which makes a species unique. This is why species often share a very similar characteristics with the parents and other offsprings.

Knowing that Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. The ecosystem will change if a new species is introduced to an unfamiliar ecosystem. If a new species of birds were to eat another animal that was supposed to be eaten by another. The food chain of the ecosystem would be changed drastically. Aka, it might make the lizards go extinct, and can possibly become abundant. Aka, overpopulating and creating havoc within the ecosystem. Thus, causing imbalance.

Answer: thee fatty acids and one glycerol molecule

Explanation:

A fat molecule consists of two kinds of parts: a glycerol backbone and three fatty acid tails. Glycerol is a small organic molecule with three hydroxyl (OH) groups, while a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group. A typical fatty acid contains 12–18 carbons, though some may have as few as 4 or as many as 36. - from Khan academy

The correct option is B: Administration of Compound 1 followed by Compound 2 after 0.5 h

Explanation:

Administering both compounds simultaneously (as suggested in option A) would mean that some cells might be exposed to and interact with compound 2 before being exposed to compound 1. It was observed by the researchers that if the chemotherapeutic agent (compound 2) is given a half hour after giving sensitization agent (compound 1) gives better results.

Answer:

Waterborne pathogens in a local river.

Explanation:

Waterborne pathogens are the diseases that are transferred through water and are the pathogenic agents (often live organisms) that cause disease in the host. Chemical, biological, and other contaminants can all lead to water contamination.

Point-source Pollution is described as pollution that originates from a single, recognizable source, such as an industrial facility or sewage treatment plant output pipe.

Nonpoint-source pollution is pollution that doesn't come from a single source, or point.

Various signs of waterborne infections can occur. The most typical symptoms of a waterborne sickness are typically diarrhea and vomiting, but there may also be issues with the skin, ear, respiratory system, or eyes.

Therefore, waterborne pathogen are the best example of point source pollution.

Answer:

Vacuole; Cell wall

Explanation:

The release of water from the VACUOLES of the cells caused the plant to wilt and droop. The CELL WALL in the plant's cells helps the plant to maintain its structure during this period of stress.

Vacuoles are organelles which help in the storage of fluids which may include water, digestion and excretion(release) of excess water in the cells.

Cell walls on the other hand helps to provide structural support in plants and usually surrounds the membranes on the outer part.

Stories differ from scientific explanations by the fact that they are based on imagination. Thus, the correct option is B.

A scientific explanation may be defined as a type of explanation that utilizes numerous observations and measurements in order to explain the fact that we see in the natural world on the basis of accurate and valid evidence.

Stories are based on imagination, while scientific explanations are based on evidence. It can not be said that stories are always negative. It may not remarkably true that stories are avoided presenting bias.

Scientific explanations always match with logical comprehension as well as the suggested evidence with respect to the fact in a systematic way.

Therefore, stories are based on imagination is that fact that differs stories from scientific explanations. Thus, the correct option is B.

Answer:

The most common type of bond formed by carbon is a covalent bond in which carbon shares electrons with other atoms. There are three major types of covalent bonds: single, double, and triple bonds. A carbon atom itself can form four single bonds. Since carbon has four valence electrons, it forms covalent bonds with four neighboring carbon atoms.

Explanation:

Carbon most often forms a covalent bond with other atoms. If the bond is with another carbon atom, it is a pure covalent (or nonpolar covalent) bond. If it is with another atom, a polar covalent bond is formed.

The most common oxidation state of carbon is +4 or -4.

Less commonly, carbon forms ionic bonds with other atoms. This occurs when there is a large electronegativity difference between carbon and the other atom.

So, it usually forms covalent bonds. So D.
