Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.
What are Prokaryotes?A prokaryote is defined as a single-celled organism that lacks a nucleus and other membrane-bound organelles. Prokaryotes were classified within the kingdom Prokaryota.
Prokaryotic cells are described as single-celled microorganisms that are the earliest known on Earth which include bacteria and archaea. Photosynthetic prokaryotes include cyanobacteria that photosynthesize that have a single cell membrane and, therefore, all reactions occur within the cytoplasm.
Bacteria are examples of the prokaryotic cell type, some example is E. coli.
Thus, Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.

How is variation introduced into populations of asexual organisms such as bacteria and amoebas?
Answer:
In asexual reproduction an exact genetic copy of the parent organism is produced. Unlike sexual reproduction, asexual reproduction only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.
Explanation:
A scientist conducted one trial of experiment and got unexpected results. How can the scientist increase confidence in the results? A). by repeating the experiment several times B). by charging the experimental procedure C). by asking other scientists what they think about the results D). by modifying the results so they are close to the expected results
Answer:
The answer is A by repeating the experiment several times
Explanation:
i did it on edu
By repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).
What is an experiment?An experiment is defined as a procedure which is carried out to support or disprove a hypothesis. It determines the efficacy or potential of something previously unusable. It provides insight into cause and effect by demonstrating what results when a particular factor is manipulated.
An experiment is defined as a type of empirical study that involves manipulation of an independent variable, measurement of a dependent variable, and control of extraneous variables. This extraneous variable is any variable other than the independent and dependent variables.
The best approach when conducting a scientific experiment is to test repeatedly and make sure the experiment can be repeated.
Thus, by repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).

Which statement describes gravity, There is no define of measurement for gravity, Gravity is the force that pulls objects towards Earth's center, Objects that have a small mass will have no gravitational pull, Gravitational pull between two objects decrease as the mass of one increases.
Answer:
Gravity is the force that pulls objects towards the earth centre.
Explanation:
According to the postulation of Sir Isaac Newton, explaining Gravity using an apple falling down from a tree. He was so curious to find out why this happened. I hope this helps.
The statement which best describes gravity is that it is the force that pulls objects toward Earth's center. Thus, the correct option for this question is B.
What is Gravity?Gravity may be defined as a type of force through which a planet or any other celestial body draws objects toward its center. It is only the force of gravity that specifically keeps all of the planets in orbit around the sun. This force attracts a body toward the center of it.
According to the context of this question, it is a fundamental interaction that causes the mutual attraction between things with mass or energy.
The best example of gravity is understood by throwing a ball high in the air, it will certainly be coming back to the surface of the earth after attaining its maximum height with respect to the energy by which is thrown.
Therefore, the statement which best describes gravity is that it is the force that pulls objects toward Earth's center. Thus, the correct option for this question is B.

Identify the living and non-living parts of the nitrogen cycle.
The nitrogen cycle is a cyclical process in which nitrogen moves through both living and non-living things, including the atmosphere, soil, water, plants, animals, and bacteria.
What is nitrogen cycle?The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.
Nitrogen fixation, nitrification, denitrification, decay, and putrefaction are some of the processes involved.
Nitrogen fixation, nitrification, and denitrification are the three major steps in the nitrogen cycle.
It is a biosphere cycle that includes the atmosphere, hydrosphere, and lithosphere. Nitrogen can be found in a variety of reservoirs.
The nitrogen cycle is a cyclical methodology in which nitrogen moves through both living and nonliving systems such as the atmosphere, soil, water, plants, animals, as well as bacteria.
