The process of mitosis divides DNA equally between two daughter cells, i.e., option B is correct.

Mitosis is a way of dividing cells in which the chromosome number remains the same as in parent cells, this is why it is also referred to as equational division.

Mitosis is the process by which a cell separates its duplicated DNA, eventually separating its nucleus in half.

Thus, the correct option is B.

The two-argument people might make for not preserving botana curus are they take a long time to grow, so it may not be worth the effort; there are organisms that are similar, and it may be expensive.

Botana curus is a precious plant because it yields Carol, a substance that can be used to treat cancer.

Curol cannot be manufactured in a lab. Botana curus grows slowly and is an endangered species, so its ability to produce large amounts of Curol is limited.

Thus, the two arguments are they take a long time to grow, so it may not be worth the effort and there are organisms that are similar, and it may be expensive.

Answer:

enzymes don't affect the free energy of the reactants or products

Explanation:

That is, they don't change whether a reaction is energy-releasing or energy-absorbing overall. That's because enzymes don't affect the free energy of the reactants or products. Instead, enzymes lower the energy of the transition state, an unstable state that products must pass through in order to become reactants.

Yes, it is possible because making a paper fold takes far less time than making a thermal or plastic item. The gravitational force is the reason behind this.

Polystyrene, a complicated substance, is used to make thermocol. When heated to over 100°C, it changes to a liquid condition and then returns to a solid state when cooled.

A gravitational force is defined as which draws particles or bodies together.

Viruses are organisms that share traits with both living and non-living organisms. The virus' genetic material is made up of both DNA and RNA.

A virus is an infectious microorganism made up of a nucleic acid segment (DNA or RNA) encased in a protein coat. A virus cannot multiply on its own; instead, it must infect cells and make copies of itself using the host cell's components. A virus frequently kills the host cell in the process, resulting in harm to the host organism.

Viruses have the following characteristics:

Viruses have an exterior capsule layer and a specified boundary. Only the host cells provide energy to the virus. They thrive and mature, multiplying their numbers solely within the host cells.

Viruses lack the following characteristics:

A virus is a single-celled animal with no more than one cell. In the virus, there is no internal organization. If a virus is present outside of the host environment, it does not grow, develop, or require energy. Viruses do not remove trash.

The average force vehicle experiences is 6000N.  The correct option is B.

It states that the force F is directly proportional to the acceleration a of the body and its mass.

F =ma

Given is a 2000kg vehicle travelling 30m/s takes 10s.

It takes t = 10s to come to rest, then the acceleration will be

a = velocity /time

a = 30/(10)

a = 3 m/s²

According to the Newton's second law of motion.

F = 2000 kg x 3 m/s²

F =6000 N

Thus, the average force vehicle experiences is 6000N.

Answer:

This graph illustrates the change in global surface temperature relative to 1951-1980 average temperatures. Nineteen of the hottest years have occurred since 2000, with the exception of 1998, which was helped by a very strong El Niño. The year 2020 tied with 2016 for the hottest year on record since record-keeping began in 1880 (source: NASA/GISS). This research is broadly consistent with similar constructions prepared by the Climatic Research Unit and the National Oceanic and Atmospheric Administration.

The time series below shows the five-year average variation of global surface temperatures. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.

The “Global Temperature” figure on the home page dashboard shows global temperature change since 1880. One gets this number by subtracting the first data point in the chart (-0.16°C) from the latest data point (0.85°C).

The exercise reduces the levels of the low-density lipoproteins or the bad cholesterol. It is found that, the people, who exercise daily have a low level of low-density lipoproteins, and an increased level of high-density lipoprotein, which is also known as good cholesterol.

Scientific hypotheses, in general, are the premises within a given theory, which can be validated on the basis of a scientific method, contributing to the formulation of new hypotheses. In this experiment the theory says that cholesterol levels between people who exercise and people who do not exercise is different. Within this theory, the statement says that people who exercise for an hour may have lower cholesterol levels, is a hypothesis that will be confirmed or refuted after the experiment.

The dependent variable is summarized in the phenomena or factors explained or identified, because they are influenced or determined by the independent variable. In this experiment the independent variable is the performance (or not) of exercises. Exercise is what influences or determines cholesterol levels in this study. Thus, cholesterol levels are a dependent variable.

Hence, to check whether a person exercises regularly or not, the scientist can determine the cholesterol level.

From the calculations, the rate of growth of the culture is 2.88.

We apply the exponential growth problem when there is an exponential increase.

Thus, we have; P =Poe^rt

P = amount at time t

Po = amount originally present

t = time taken

r = rate of growth

1.6 × 10^6 = 16e^4r

1.6 × 10^6/16 = e^4r
