What is the circumference of a circle

According to the research, the correct answer is the electron carrier NADH is used exclusively in the production of ATP because they are electron-donor molecules that lead to the synthesis of ATP, whereas it phosphorylated form (NADPH) is used in anabolism to generate larger molecules or macromolecules.

It is the molecule made up of two nucleotides, one adenine and the other nicotinamide, which can be in oxidized or reduced form, acting as an exchanger of reducing power in metabolism.

In this sense, anabolic pathways use chemical energy in the form of ATP and NADPH obtained by reducing NADP+ by accepting electrons from water, a donor that is oxidized to synthesize cellular components from simpler molecules obtained in different ways by different types of cells.

Therefore, we can conclude that according to the research, the correct answer is the electron carrier NADH is used exclusively in the production of ATP because they are electron-donor molecules that lead to the synthesis of ATP, whereas it phosphorylated form (NADPH) is used in anabolism to generate larger molecules or macromolecules.

According to the result of Ostfeld et al., the type of forest that is most likely to have high predators is the site surrounded by at least 1 kilometer of the forest. Thus, the correct option for this question is C.

Predators may be defined as the type of animals/organisms that primarily obtains food by killing and hunting other organisms and finally consuming them. In a more simple sense, predators may be characterized as an animal that naturally preys on others.

The results of Ostfeld et al. 2018 paper, the area that is surrounded by at least 1 kilometer of the forest is known as the zone of predators, where a high number of predators are found. This is because in this region predators got an extremely good amount of food with less expenditure of energy.

The ecological pyramids help us analyze energy flow through trophic levels because it provides information about organism and its population.

Ecological pyramids help to analyze energy flow through trophic levels because it has a brief explanation about the type of organism in each trophic level. It also gives information about feeding behaviour and population of organisms in it.

Matter flows between trophic levels and among ecosystems through feeding of one organism to another.

Liquid water evaporates in the form of water vapor. This water vapor condenses to form clouds and falls back to the earth in the form of rain and snow.

The importance of the nutrient cycles is storage of elements, which is important because some organisms require a small quantity of a particular nutrient in order to survive.

If sufficient sunlight and water are available to the producers, then the primary productivity increases in that ecosystem. We know that the primary productivity of an ecosystem is limited and controlled by the availability of nutrients.

If a DNA molecule is 10% Adenine (A), 40% of the DNA molecule

is made up of Cytosine (C)

The DNA composition ratio can be calculated by Chargaff's rule which states that, Guanine and cytosine should both be present in equal amounts in the DNA of every species and organism, while adenine and thymine should both be present in equal amounts. Additionally, there should be a 1:1 stoichiometric ratio between the purine and pyrimidine bases (A+G=T+C).

As per the Question,

If, A=10 then T=10 because A always pair with T. If T=10, then G=40, and then C=40. The total sum is equal to 100 or A + G (10 + 40) = T + C (10 + 40). Which ratio is equal to 1:1.

Bacteria are the microorganisms that are the most primitive on earth. These are omnipresent. Bacteria can be both harmful as well as useful. The bad bacteria cause several diseases whereas the good bacteria help in digestion, nitrogen fixation, curdling of milk, etc.

Phagocytosis is a type of endocytosis. It is also called cell-eating. In phagocytosis, cell engulfs solid large bacteria completely. This is done by forming extensions of the plasma membrane called pseudopodia. These pseudopodia then fuse and pinch off to form endocytic vesicles.

In order to produce an incubated plate with a readily countable number of colonies, serial dilution is employed in microbiology to measure the concentration or number of cells/organisms in a sample. To get the appropriate concentration of reagents and chemicals from a greater concentration, serial dilution is employed in biochemistry.

The concentration of an organism, in this case bacteria, is systematically lowered through successive resuspension in predetermined amounts of liquid diluent through the technique of serial dilution.
