Glucose is the carbohydrate produced by photosynthesis. Energy-rich glucose is delivered through your blood to each of your cells.while glucose is a usable form of energy.

ATP is the usable form of energy for your cells.ATP is a storable form of energy

Explanation:

The difference between ATP and glucose, is glucose is a storable form of energy, while ATP is a usable form of energy. Thus, option D is correct.

ATP or Adenosine triphosphate principal energy currency of the cell.

It is the byproduct of  photophosphorylation, cellular respiration, and fermentation process. It is highly soluble in water.

Beside energy source, ATP have a role in signal transduction pathways  and DNA synthesis.

Structurally ATP is a nucleotide which made up of adenosine molecule  and three phosphate molecules.

The three phosphate molecules are connected by two phospho-anhydride bonds which releases huge amount of energy upon hydrolysis.

After hydrolysis of ATP is converted into adenosine diphosphate (ADP) energy is released.

In ATP hydrolysis, removal of  one phosphate group releases  7.3 kilocalories per mole, or 30.6 kilojoules per mole.  

Thus, option D is correct.

The standard Mendelian ratio for a dihybrid cross, in which the alleles of two distinct genes assort independently into gametes, is 9:3:3:1.

The alleles in the pair, whether they are both dominant or both recessive, are the same, so the term "homozygous" is used to characterize the pairs "AA" and "aa." The allelic pair "Aa" is referred to as heterozygous, in contrast.

In terms of genetics, being homozygous means that you have inherited the identical alleles of a particular genomic marker from both of your biological parents. As a result, a person who possesses two identical copies of a genetic marker is said to be homozygous.

the answer to the question is D

Answer: D (migratory animals, oxen, caribou, and arctic foxes)

Explanation: Migratory animals stay in the tundra during the "summer" months but leave during the colder and harsher months. The oxen and caribou have lower surface area to volume ratio which makes less heat able to dissipate into the surrounding area. They also have thick coats. In the summer fox are able to raise their young and prey on the birds and such that may migrate there.

The animals which live in the normal conditions live in this area. The correct statement is option D.

The most common animal in Tundra is the Arctic Fox.

Tundra wildlife usually contains the animals such as the The arctic foxes, migratory animals, oxen and caribou. There are harsh conditions in the winter thus the animals tend to elope from such areas in this case they are saved from the adverse effects of the weather and the climatic conditions.

The arctic fox is one of the most common animals that are found in the Tundra as the fox has thick skin with the property that it turns from brown to white in winter and the large body of them helps to preserve the heat that helps them to get saved from the adverse effects of temperature.

Montesquieu can be credited with inspiring the Founder's use of separation of powers in the Constitution.

Montesquieu was a French political philosopher who wrote extensively on the subject of government and its organization.

He argued that the best way to prevent tyranny and ensure the protection of individual liberty was to divide the powers of government among different branches or institutions, each with its own distinct role and responsibilities.

This idea was influential in the development of the U.S. Constitution, which established a system of government with three separate branches: the legislative, executive, and judicial branches.

Overall, the population shift in South Africa has had a negative impact on agriculture, leading to a decline in the sector and decreased food security for rural communities.

Population refers to the total number of individuals of a particular species or group living in a specific area or region. In the context of human populations, it refers to the number of people living in a particular geographic area or country. Population can also refer to subgroups within a larger population, such as age groups, ethnic or racial groups, or socioeconomic groups. Population can be measured and analyzed in various ways, including through demographic data such as birth and death rates, migration patterns, and population density.

Here,

Over the past 50 years, there has been a significant population shift in South Africa, with many people moving from rural areas to urban areas in search of better economic opportunities, education, and healthcare. This trend is known as urbanization and is a common phenomenon in many developing countries.

As people move from rural areas to urban areas, the population density in urban areas increases, while rural areas become less populated. This population shift has had a significant impact on agriculture in South Africa. As more people move to cities, there is less demand for agricultural products, leading to a decline in the agricultural sector. This has resulted in the loss of agricultural land, reduced productivity, and decreased food security for rural communities.

In addition, the population shift has also led to changes in land use. As urban areas expand, they often encroach on agricultural land, leading to land fragmentation and reduced agricultural productivity. This can also lead to conflicts between urban and rural communities over land use and resource allocation.
