C. Experimental
Explanation - The cause and effect of a process would be studied in experimental investigations. However, in descriptive studies, relationship between the factors are not studies rather the detail of the process is studied. In comparative investigation, several factors are compared and its effects are analyzed.
In experimental investigations, experiments are carried out based on the hypothesis and then it is validated accordingly. Validation is a must to prove and disprove the hypothesis. Therefore, experimental data and hypothesis are related.
Answer:
Option B,
Explanation:
Proper restraint and handling techniques are used while dealing with animals in laboratory. These techniques ease the process of dealing with animals and must be practiced on regular basis even when there is no procedure being performed.
Unlike other animals cat is the most co-operative animals and it is usually dealt by restraining the body be one hand and head by other hand. Cats can also be restrained by holding the scruff with one hand and then gently holding the hind limbs followed by stretching it.
Hence, option B is correct.
Answer:
traits that hinder survival eventually disappear
Explanation:
living things adapt to their surroundings
Answer:
<h2> any organism containing the DNA of interest</h2>
Explanation:
- Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
- In such type of the process, the branch of biological science that is known as biotechnology is used.
- In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
- Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.
It is called the Rugae.
Rugae is a term used in anatomy to refer to a series of ridges produced by folding of the wall of an organ. For example the gastric rugae which allows for expansion of the stomach after the consumption of foods and drinks. The rugae of the vagina are the transverse ridges on the mucous membrane lining the vagina. They allow the vagina to stretch during childbirth.
