<u>Answer</u>: Ionic bond
<u>Explanation</u>:
- An ionic bond is a type of a chemical bond formed by the complete transfer of electrons from one atom to another atom i.e one of the atoms loses its electrons and the other gains it. This results in the formation of 2 oppositely charged ions.
- In sodium chloride, sodium loses one electron from its outermost shell (valence shell) whereas chloride gains it. Due to this sodium gains, a net positive charge and chloride gain a net negative charge.
- So, due to the complete transfer of electrons that takes place from sodium to chloride, the compound generated (Sodium chloride) has an ionic bond.
<h2>(Answer 1 points 3)</h2><h2>A. Taxon</h2><h3>3. the categories used in classifying organisms.</h3><h2>Explanation:</h2>
In other words, we can also say that taxon is also known as a taxonomic group of any rank, such as a species, family, or class. It is a group of one or more than one different populations of an organism or the organisms viewed by taxonomists to make a system. These are the rules for naming new animals.
<h2>(Answer 2 points 3)</h2><h2>B. Taxonomy</h2><h3>1. the science of the classification of organisms.</h3><h2>Explanation:</h2>
A taxonomy is said to be a scheme of classification or in other words, we can also define the term taxonomy as the branch of science involved with classification, especially of organisms, systematics. Organisms are grouped together. This science of gives name, describe and classify the organisms including all the plants, animals and the microorganisms of the world.
<h2>(Answer 3 points 3)</h2><h2>C. Family</h2><h3>4. A taxonomic category containing a group of similar genera.</h3><h2>Explanation:</h2>
Family is the one that has been classified between order and genus. A family is also divided into the subfamilies. It is one of the eight main and important taxonomic levels. It is a primary taxonomic category of organisms ranking. This category comes on the sixth number of all the categories lies in a taxonomic group.
<h2>(Answer 4 points 3)</h2><h2>D. domain</h2><h3>2. The largest taxonomic category.</h3><h2>Explanation:</h2>
In the three-domain system of taxonomy, if we talk about the domain then we would define it as the superkingdom or empire. It can also be said to be as it is the highest taxonomic rank of organisms. It is a taxonomic category above the kingdom level. There are three domain such as Bacteria, Archean, and Eukarya, which we can say are the major categories of life.
Answer:
it is located across the forehead.
The answer is D. The natural selection is a theory which illustrates the gradual process of evolution in the population due to the change of environment. The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.
