Which event is NOT part of the process of DNA replication?

1.Ribosomes are synthesized.
2.Hydrogen bonds are broken.
3.Nitrogenous base pairs are formed.
4.A double-stranded molecule unwinds.

The final electron-accepting molecule in the electron transport chain is oxygen.

Oxygen mainly acts as an electron acceptor in the electron transport chain. More specifically, it acts as the final electron acceptor to ensure that oxidative phosphorylation takes place.

Without this final electron acceptor, the electron transport chain will not be able to complete the cycle, and energy molecules in the form of ATP will not be formed.

A plant is homozygous for the production of yellow seeds (YY) and homozygous for wrinkled seeds, possible gametes will this plant produce (r) Y, y, and r only. Thus, option "C" is correct.

The plant is heterozygous (Yy) for the color of seed and homozygous (rr) for the shape of the seed.

For the color of the seed, there are two alleles that will take part in gametes formation are (Y) n (y) while for the shape of seed is have only two recessive alleles (r).  

So, by the assortment of (Y) n (r) the first gamete will be (Yr) and an assortment of (y) n (r) second gamete will be (yr).

Thus, the correct answer is option C. Yr and yr only.

Answer:

Density Independent

Explanation:

Density independent is the factor that will affect a population no matter its size. Temperature, natural disasters, and oxygen levels all influence this.

The correct term to describe the type of limiting factor that causes the destruction of both the small population of trees and the large population of birds in this scenario is "density-independent." Density-independent factors are environmental factors or events that affect populations regardless of their size or density.

Density-independent factors are environmental factors or events that affect populations regardless of their size or density. These factors exert their influence on population dynamics independently of population density. Density-independent factors include natural disasters like earthquakes, floods, hurricanes, and forest fires, as well as extreme weather events, habitat destruction, pollution, and certain diseases.

In this case, the forest fire is an example of a density-independent factor because it can impact both the tree population and bird population regardless of their respective sizes or densities.

Therefore, the correct answer is "density-independent."

Explanation:

Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen).

During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise. As byproducts, carbon dioxide and water are produced.

The Krebs cycle, oxidative phosphorylation, and glycolysis—an anaerobic process—are the three phases of aerobic cellular respiration.

All forms of cellular respiration begin with glycolysis, which is anaerobic and oxygen-free. The pathway will go on to the Krebs cycle and oxidative phosphorylation if oxygen is present. However, some species may engage in fermentation to continuously manufacture ATP in the absence of oxygen.

Total amount of ATP molecules generated during aerobic respiration from a single glucose molecule.

During glycolysis:

As 2ATP

From 2NADH 5ATP (oxidation phosphorylation)

In pyruvate oxidation;

From 2NADH 5ATP (oxidative phosphorylation)

Citric acid cycle;

individual behavior

Explanation:

if the mice are competing with each other that means that it's every man for himself.

The given example suggests the individual behavior of the mice because they change their behavior according to conditions.

In nature, organisms search for resources first, and if this availability is fulfilled, they reproduce themselves and increase the number of offsprings, but when the availability of resources are depleted they compete with each other.

The individual behavior of the mice in the population is defined as some mice fighting for the same resources and others mating with each other.

In the given question interspecific competition is not a right choice because it is the competition between the organism of two different species for the same resources.

Explanation:

Answer:

51.84%

Explanation:

p² + 2pq + q² = 1 and p + q = 1

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p²  = percentage of homozygous dominant individuals

q²  = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

p = 0.72 => p² = 0.72² = 0.5184

=> Percentage of the rats are normal sized: 51.84%

(c)Low Temperature of the Reactants can decrease the rate of a chemical reaction.

How temperature effects the rate of a chemical reaction

Chemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Thus decrease in the temperature of a reaction can help in decreasing the rate of a chemical reaction.Lower the temperature lower the chemical reaction rate.
