The correct word is chromatin.
What are chromatins?Chromatin is a mixture of decondensed chromosomes and proteins. The chromosomes are responsible for storing genetic information and transferring such from one generation to the other.
When cells are in active divisions, the chromatin condenses and the tangle of fine fibers become visible under the microscope as chromosomes.
Once active divisions are over, the chromosomes decondense back to their natural states.
Thus, in cells that are not dividing, chromosomes uncoil to form a tangle of fine fibers known as chromatin.

What is the end result of each of these three major steps during cellular respiration?
The end result of each of these three major steps during cellular respiration are here:
Glycolysis - 2 molecules of pyruvic acid and 2 ATP.
Kreb's cycle - 6NADH, [tex]FADH_{2}[/tex], and 2 ATP and [tex]4CO_{2}[/tex].
Oxidative phospholyration - ATP and water.
What is Glycolysis?In the process of glycolysis, the six-carbon sugar molecule glucose is split into two molecules with three carbons (pyruvic acid). Two molecules of ATP are produced when the energy from the broken bonds is caught.What is Kreb's cycle?The three-carbon molecules produced by glycolysis are converted into carbon dioxide molecules by the Krebs cycle. ATP and NADH are produced as an electron donor via the Krebs cycle as well as glycolysis.What is oxidative phosphorylation?Water is created by combining oxygen with the hydrogen atoms of NADH in the electron transport chain. Energy is constantly being taken in during electron transit to create ATP. The procedure is occasionally referred to as oxidative phosphorylation since it needs oxygen.Learn more about cellular respiration here:

The succinate dehydrogenase reaction is unusual for a dehydrogenase because it uses ________ as an electron acceptor (oxidizing agent) that is regenerated by ubiquinone
The succinate dehydrogenase reaction is unusual for a dehydrogenase because it uses FAD as an electron acceptor.
What is FAD?Flavin adenine dinucleotide (FAD) is a redox-active coenzyme linked to various proteins that participates across several metabolic enzyme reactions.
A flavoprotein is a protein that contains a flavin group, which can be FAD or flavin mononucleotide (FMN).
Since it uses FAD as an electron acceptor that is regenerated by ubiquinone, the succinate dehydrogenase reaction is peculiar for a dehydrogenase.

3-phosphoglycerate is the product formed in the first substrate level phosphorylation in glycolysis.
A cytoplasmic mechanism called glycolysis converts glucose into two molecules with three carbons each and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose. This reaction uses adenosine triphosphate (ATP), and the end result, glucose-6-P, inhibits hexokinase.In contrast to oxidative phosphorylation, which produces ATP from ADP and an inorganic phosphate, Pi, substrate-level phosphorylation produces ATP from ADP and a phosphorylated intermediate. The amount of ATP produced by glycolysis is not very high.At the first substrate level of glycolysis, 3-phosphoglycerate is created from 1,3-bisphosphoglycerate

The causative agent of gonorrhea and one of the causative agents of meningitis is part of which subgroup of proteobacteria?
The causative agent of gonorrhea and one of the causative agents of meningitis is part of Diplococci subgroup of proteobacteria.
Diplococci
In essence, diplococci bacteria are paired, spherical, or rounded bacteria. Some bacteria may appear ovoid (elongated) or bean-shaped, unlike staphylococci bacteria, which form grape-like clusters and are genuinely round.
Numerous infections in humans can be brought on by both Gram-positive and Gram-negative bacteria. The shape of diplococci bacteria can be spherical or elongated, as was previously mentioned. Therefore, some species—such as those of the staphylococci bacteria—might not be perfectly round. Because of this, they are frequently referred to as having an ovococcoid shape. Several studies have suggested that this form is the result of two different peptidoglycan machineries. The cell division machinery is in charge of producing septal peptidoglycan, which leads to the formation of the cell wall, in coccoids (really round bacteria), such as Staphylococcus aureus and Micrococcus.

A. Produce gametes and produce hormones
The two major functions of the gonads in the adult are steroid hormone production and gametogenesis.
The gonads, the primary reproductive organs, are the testes in the male and the ovaries in the female. These organs are responsible for producing the sperm and ova, but they also secrete hormones and are considered to be endocrine glands.
Gonads are male sex glands. They produce sex hormones and sex cells. In the male, the interstitial cells of the testes produce and secrete the male sex hormone testosterone. This controls the development and function of the male secondary sex organs, as well as the secondary sexual characteristics.

The major differenc ebetween the use of scrubber and the use of fluidiozed - bed combustions as pollution control measures in power plants is?
The major difference between the use of scrubbers and the use of fluidized - bed combustions as pollution control measures in power plants is that fluidized bed combustions usually operate at a lower temperature whereas scrubbers require higher temperatures.
Mixing crushed coal with limestone is a part of fluidized bed combustion.
The limestone neutralizes a large portion of the sulphur dioxide in the coal. Finally, steam is produced by boiling water using the heat produced by combustion.
With the help of gas, water, and air, a scrubber may separate and remove particles that are in liquid or sludge form or that escape as clean gas.
In some circumstances, water droplets scrape sulphur dioxide and particles from exhaust streams, converting them to sludge that can be disposed of later.
The process starts with dirty air entering, combustion exhaust steam moving upward in mist, mist collecting particles and bringing them to the bottom of the unit, dirty water moving sludge to a removal system, sludge is separated from water and disposed of, water moving to the scrubber for reuse, mist collecting on screen, and clear air exiting.

Why does a coastal area have less variation in temperature than a noncoastal area?
• Temperatures feel cool all year round due to the duration of daylight.

• The temperatures on land change more rapidly than temperatures on water.
O The air is warm because warm water moves from the equator to the poles.
The temperatures on land change more rapidly than temperatures on water.
1-The air above sand warms up and rises during the day because the land heats up more quickly than the sea, while the cool air above the water travels towards the land to take its place.
