The term defined as food components such as fibers that are not digested by the human body but are used as food by the GI bacteria to promote their growth and activity is prebiotics.
<h3>WHAT ARE PREBIOTICS?</h3>
Prebiotics are food components like carbohydrates and fibres that feed the beneficial bacteria in human gut.
Humans don’t normally digest prebiotics directly, however, the microbes in our gut can use them for their growth and development.
Therefore, the term defined as food components such as fibers that are not digested by the human body but are used as food by the GI bacteria to promote their growth and activity is prebiotics.

Answer:
The correct answer is the third statement.
Explanation:
In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.
When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.

Explanation:
22. Robert Hooke was an English scientist, but he did publish his microscopic observations
23. Anthrax is an infectious disease caused by rod-shaped bacteria known as Bacillus anthracis. It is quite common in livestock and can be passed to humans
24. Vaccinations are a direct application of the study of microbes. Microbes are directly used in the production of viruses - a small amonut of the microbes or its proteins can invoke an immune response that the body will remember the next time it is exposed to the pathogen.
25. Telocentric chromosomes have their centromere located at one end of the chromosome. The ends of the chromosome are called telomeres.
26. Louis Pasteur disproved the theory of spontaneous generation with his famous swan-neck flask experiment. He found that microorganisms could not grow in sterile conditions. He then proposed that “life only comes from life.”
27. The germ theory is the idea that pathogens (microorganisms) can cause disease. Before that, the working theory was than diseases spontaneously generated.
28. When chromosomes are duplicated during DNA replication before mitosis, the two identical chromosomes are called sister chromatids
29. A microscope is a tool that allows researchers to see very small structures
30. The cell membrane is composed of a lipid bilayer that surrounds the cell and controls the entry and exist of substances.
DNA; maintain sequence of amino acids.
RNA; carry sequence of DNA from nucleolus into outer matrix to be transcripted
The step that relates to the energy transformation in photosynthesis is respiration.
<h3>What is respiration?</h3>
Respiration is the process whereby the chemical energy locked up in carbohydrates is unlocked into another energy form that is usable to living organisms.
In other words, chemical energy in carbohydrates is converted to ATP. This process can take place with (aerobic respiration) or without (anaerobic respiration) oxygen.
Carbohydrates are primarily generated from photosynthesis by green plants.
