Answer:

insect control

Explanation:

The control of rickettsial infections requires the control of insects.

Rickettsial infections are caused by obligately intracellular Gram-negative bacteria that can only live inside a host organism. The host organisms are usually insects such as ticks, fleas, lice, etc. and a bite from any of the insects hosting the bacteria represents the only through which the infections are transmitted.

Hence, controlling the insects that serve as hosts for the bacteria will go a long way in controlling rickettsial infections.

Answer:

Chemo-synthesis

Explanation:

Chemo-synthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food in the absence of sunlight.

Answer:

The correct answer is - reduction by accepting an electron from NADH.

Explanation:

During fermentation, the conversion of the pyruvate into lactic acid takes place which is a part of the anaerobic process. This process required a reducing agent to accept the electron by pyruvate and convert it to lactic acid.

Pyruvate + NADH → Lactic acid + NAD+

NADH oxidized again for the glycolysis process in anaerobic conditions.

B lymphocytes or B-cells are responsible for producing antibodies when antigens enter the body.

An antibody may be defined as a protein produced by plasma cells in response to a specific antigen.

The major function of an antibody is to eliminate disease-causing organisms which are known as pathogens and barricade them from contaminating human cells.

Plasma cells of the body produce B cells and memory. B cells play an essential role in producing antibodies while memory cells initiate the process of secondary infection.

The complete question is as follows:

Therefore, B lymphocytes or B-cells are responsible for producing antibodies when antigens enter the body. Hence, the correct option is A.

Answer: it's Chromatin

because Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Chromatin consists of complexes of small proteins known as histones and DNA. hope this helps have a nice day ❤️❤️❤️

Answer:B

Explanation:

Answer:

The rock cycle and water cycle overlap with erosion, transporting, and deposition.carbon atoms are used repeatedly on Earth and cycled between the atmosphere, hydrosphere, biosphere, and lithosphere through processes

Explanation:

The rock cycle and the carbon cycle are two different types of natural cycles that occur on earth. The difference include components, processes, time scale, human impact, and environmental implications.

The rock cycle is a continuous process that occurs over millions of years, during which rocks are transformed from one type to another. There are three major types of rocks: igneous, sedimentary, and metamorphic. Each type of rock is formed through a different process.

The carbon cycle is the process by which carbon is cycled between the atmosphere, oceans, and living organisms. Carbon is essential for life, and is found in all living organisms. The carbon cycle is driven by photosynthesis, respiration, and decomposition.

During photosynthesis, plants absorb carbon dioxide from the atmosphere and use it to build organic molecules. These organic molecules are then consumed by other organisms, and carbon is transferred up the food chain.

When organisms die, their bodies are decomposed by bacteria and fungi, which release carbon dioxide back into the atmosphere.

In addition, carbon is stored in fossil fuels such as coal, oil, and natural gas, which are formed from the remains of ancient plants and animals. When these fuels are burned, carbon is released into the atmosphere, contributing to global warming.

Answer:

D

Explanation:

fungi are heterotropic therefore they cannot produce their own food. plants can since they are autotrophic

The new scientific knowledge led to their current classification into separate kingdoms as It was discovered that fungi are heterotrophic. Thus, option D is correct.

Fungi and plants are currently classified into two distinct kingdoms. However, due to some of their common observed features, they were once classified together as one kingdom. Fungi are a group of heterotrophic organisms that possess cell well while Plants are group of autotrophic organisms that also possess cell wall.

Previously, the observable similar features were the basis of classification of organisms. It was observed that fungi and plants were nonmotile i.e. cannot locomote, and possessed a fixed body structure that grew out of the soil (fungi mushroom).

Therefore, The new scientific knowledge led to their current classification into separate kingdoms as It was discovered that fungi are heterotrophic. Thus, option D is correct.

Answer:

If the patient's blood is too low in ions, they will diffuse from the dialysis fluid into the blood, restoring the ideal level in the blood. If the patient's blood is too high in ions, the excess ions will diffuse from the blood to the dialysis fluid.

Explanation:

I may be wrong but yeh

If the patient's blood is too low in ions, they will diffuse from the dialysis fluid into the blood, restoring the ideal level in the blood. If the patient's blood is too high in ions, the excess ions will diffuse from the blood to the dialysis fluid.

Dialysis is a procedure to remove waste products and excess fluid from the blood when the kidneys stop working properly. It often involves diverting blood to a machine to be cleaned.

Moreover, hemodialysis is most often done at a special dialysis center. You will have about 3 treatments a week. Treatment takes about 3 to 4 hours each time.

In hemodialysis, the wastes and excess water are removed by using an external filter called a dialyzer, which contains a semipermeable membrane.
