A nitrogenous base, or nitrogen-containing base, is an organic molecule with a nitrogen atom that has the chemical properties of a base. The main biological function of a nitrogenous base is to bond nucleic acids together. A nitrogenous base owes its basic properties to the lone pair of electrons of a nitrogen atom.
<span>Biological scientists are research scientists who examine how living organisms relate to the environment. They can specialize in any number of plant, animal or environmental studies. Biological scientists most often have earned a master's or doctoral degree in their specialization; such degrees offer the opportunity to develop research while finishing their education. Some low-level positions related to biological science are available to those holding baccalaureate degrees.</span>

Complete Question:
Which Kingdom of living things consists entirely of multi-celled, heterotrophic organisms?
A) Animal
B) Fungi
C) Plant
D) Protist
<u>Correct Option:</u>
<u>Animal</u> Kingdom of living things consists entirely of multi-celled, heterotrophic organisms.
Option: A
<u>Explanation:</u>
The system of scientific classification in biological science is categorized into seven main groups: kingdom > phylum > class > order > family > genus > species. Here the kingdom is the largest group while smallest is the species. The term phylum is being used in the Kingdom of Animals, and is the second largest group.
The Kingdom of Animals is made up of multi-cellular, heterotrophic species which feed on other entities to survive. Some of the animal properties in this kingdom are able to establish, function independently, and reproduce during their existence.
Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:
1. State the hypothesis
2. Formulate an analysis plan
3. Analyzing the data obtained
4. Final step is to analyze the results
There are three types of variables taken in an experiment:
1. Independent variable: light, temperature, humidity
2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives
3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil
