Answer:

Limestone

Explanation:

The most common chemical sedimentary rock, by far, is limestone. Others include chert, banded iron formation, and a variety of rocks that form when bodies of water evaporate. Biological processes are important in the formation of some chemical sedimentary rocks, especially limestone and chert.

According to the research, in photosynthesis, through the light-dependent reactions energy is contained in the NADPH and ATP molecules that is used by light-independent reactions.

It is the process that converts solar energy into chemical energy which, stored in cells, allows the formation of carbohydrates and other organic molecules.

In this sense, the light-dependent reactions occur in the thylakoids whose chemical energy is comprised of molecules of two types NADPH and ATP.

On the other hand, light-independent reactions occur in the chloroplast matrix with the intervention of enzymes that intervene in the reduction of CO2 molecules to establish carbohydrates through the energy sources ATP and NADPH.

Therefore, we can conclude that the light-dependent reactions in photosynthesis manufacture ATP and the reducing source NADPH necessary for light-independent reactions.

The lack of centrosomes at the poles to which the microtubules attach in plant cells, in contrast to animal cells, is a significant difference between the two types of cells. The spindles are connected to the kinetochore by the chromatids (condensed, duplicated chromosomes).

The cytokinesis stage of mitosis is the most significant distinction between plant and animal cells. When a cell divides, an animal forms a cleavage while a cell plate forms in plants. In addition, as plants grow, their cells can lengthen. Not just in the meristems, but all over the plant, this procedure is known as cell elongation. Animals are not capable of cell elongation.

Nitrate in groundwater can be increased by the infiltration of runoff from various sources, including manure from cattle feedlots, fields treated with synthetic fertilizers containing nitrogen, and rain runoff with dissolved nutrients.

Hence, the correct option is D.

Nitrate in groundwater can be increased by the infiltration of runoff from various sources, including manure from cattle feedlots, fields treated with synthetic fertilizers containing nitrogen, and rain runoff with dissolved nutrients. These sources can contribute to the contamination of groundwater with nitrates.

Manure from cattle feedlots often contains high levels of nitrogen, which can leach into the soil and eventually reach groundwater.

Similarly, synthetic fertilizers used in agricultural fields contain nitrogen compounds that can also be washed into the soil and groundwater through runoff. Additionally, rainwater carrying dissolved nutrients can infiltrate the ground and contribute to nitrate contamination.

Therefore, all of the given options can contribute to the increase of nitrate in groundwater through runoff infiltration.

Hence, the correct option is D.

Answer:

Constante de resorte, k = 19.745 N/m

Explanation:

Dados los siguientes datos;

Masa, m = 2 kg

Periodo, T = 2 segundos

Para encontrar la constante del resorte, k;

\( Period, \; T = 2 \pi \sqrt {\frac {m}{k}} \)

Dónde;

Haciendo k el tema de la fórmula, tenemos;

\( k = \frac {(2 \pi )^{2}m}{T^{2}} \)

Sustituyendo en la fórmula, tenemos;

\( k = \frac {(2 * 3.142)^{2} * 2}{2^{2}} \)

\( k = \frac {6.284^{2} * 2}{4} \)

\( k = \frac {39.49 * 2}{4} \)

\( k = \frac {78.98}{4} \)

Constante de resorte, k = 19.745 N/m

The term "maximum sustainable yield" refers to the maximum number of individuals of a particular species that can be harvested without causing long-term damage to the population or ecosystem.

This group of answer choices occurs closer to the carrying capacity, which is the maximum number of individuals of a species that a particular ecosystem can support over the long term.

In order to achieve maximum sustainable yield, it is important to harvest using the appropriate methods and at the appropriate times. Harvesting too many individuals too quickly can lead to a decline in the population, which can have negative consequences for the ecosystem as a whole.

If there exists a 50 percent chance that a child will have dimpled cheeks, the parental genotypes must be: Aa and Aa.

In offspring each parent provides one alleles . Thus, Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically. While aa individuals will always have recessive trait.

Many characteristics in human are controlled by dominant alleles such as Dark hair is dominant over blonde or red hair. These traits can be expressed by dominant alleles homozygous dominant or one dominant and one recessive allele heterozygous dominant.

Once habituation occurs, a new stimulus causes responsiveness to return to a high level. This increase is called recovery.

Habituation is one of the simplest and commonly chosen forms of learning. It lets people tune out unnecessary stimuli and focus on the things that matter. Habituation is something that is happening on a daily basis at the time of any kind of learning but the person is usually unaware of it.

C. Compound Light Microscope

Explanation:

Each of the following events affect the outcome of mitosis or meiosis, the correct answer is a. mitotic cohesion fails to form early in mitosis because  it will lead to sister chromatids that cannot properly align at the metaphase plate.

Consequently, the incorrect distribution of chromosomes during anaphase would result in daughter cells with an abnormal number of chromosomes.

b. If shugoshin is absent during meiosis, it will cause the cohesion holding the sister chromatids together to degrade too early, resulting in premature separation of the sister chromatids during meiosis I.

This will cause an incorrect distribution of chromosomes during anaphase I and daughter cells will have an abnormal number of chromosomes.

c. If shugoshin does not break down after anaphase I of meiosis, it will cause the cohesin that holds the sister chromatids together to remain intact, preventing the sister chromatids from separating during anaphase II.

This will result in daughter cells that have an abnormal number of chromosomes.

d. If separase is defective, it will prevent the cohesion that holds the sister chromatids together from degrading during anaphase of mitosis or anaphase II of meiosis.

This will lead to the sister chromatids failing to separate, causing the daughter cells to have an abnormal number of chromosomes.

Therefore, the correct answer is a. mitotic cohesion fails to form early in mitosis .
