Which organisms transform nitrogen to a form that is useful to plants

Evolution by natural selection refers to the mechanism that is responsible for species’ survival, diversification, and extinction. The two requirements that are fundamental to the process of natural selection include; differential survival and reproduction and heritability of phenotypic variation.

The heritability of traits that allow individuals to survive and reproduce can lead to differential survival of individuals that possess them, which results in a change in the frequency of these traits within a population over time. This process is known as natural selection.The correct answer to the question is option B: II, IV, and V. Natural selection requires several factors to bring about evolution. The three requirements for evolution by natural selection are differential survival and reproduction, variation in phenotype, and heritability of phenotypic variation. Sexual reproduction also influences evolution, but it is not a requirement for natural selection.

Natural selection and evolution occur in the following way: there is a variation in a trait, the variation leads to differential survival, and over time, the trait becomes more or less frequent. When the frequency of a trait changes due to natural selection, it leads to evolution. Hence, options II, IV, and V are requirements for evolution by natural selection.

Pluripotent stem cells can become any kind of cell in the animal's body. Option D is the correct answer.

This refers to a type of stem cell that have the ability to differentiate into any of the three germ layers that give rise to all the different cell types in an animal's body. These germ layers include the ectoderm, endoderm, and mesoderm, and pluripotent stem cells can differentiate into any cell type derived from these layers.

During embryonic development, pluripotent stem cells are present in the inner cell mass of the blastocyst, which is formed from the zygote after several rounds of cell division. These cells then give rise to the various tissues and organs in the developing embryo.

Pluripotent stem cells can also be derived from adult tissues, but their potential to differentiate into different cell types is more limited compared to embryonic pluripotent stem cells. In some cases, these adult-derived pluripotent stem cells can be used to repair damaged tissues in the body.

Water enters a cell and waste material leave the cell through the membrane. Based on this information, the cell membrane is selectively permeable.

The cell membrane is a biological membrane that serves to separate and protect the cellular interior from the outside environment. This function of the cell membrane is performed by all cells.

A cell's defense comes in the form of its plasma membrane, also known as the cell membrane. Additionally, it maintains a consistent environment on the inside of the cell, which is only one of the many roles that membrane plays in the cell. One of its functions is to transfer nutrients into the cell, while another is to move harmful compounds away from the cell.

Answer: Chloroplast

Explanation:

Plants and some algae have chloroplasts responsible for photosynthesis. Plants undergo photosynthesis to transform light energy into chemical energy. This energy is stored in the form of sugar to support their growth and provide energy. Chloroplasts have a double membrane, with the thylakoid membrane located within the inner membrane.

Photosynthesis occurs within the thylakoid membrane, which is folded into sacs called thylakoids. Chlorophyll, a green pigment, is present in the thylakoids and it absorbs light energy to split water molecules into hydrogen and oxygen. The oxygen is released into the atmosphere while the hydrogen is used to create ATP, a molecule that stores energy. ATP and hydrogen are then utilized to make sugar, the final product of photosynthesis.

Explanation:

because of mitosis process

Adenosine Triphosphate (ATP) is a compound that is synthesized (created) during a process that begins with photosynthesis.

Photosynthesis is the process in which plants absorb the energy of the sun and use it to form chemical bonds between carbon atoms. This energy is stored in the form of nitrogen and is then released, forming amino acids.

Amino acids are the building blocks of proteins and are further broken down into smaller parts by digestive enzymes. This energy is then used to fuel the processes of the body, such as cellular respiration, movement, and growth. During cellular respiration, energy stored in the chemical bonds of the amino acids is released and converted into Adenosine Triphosphate (ATP).

ATP is a high-energy compound that is used to power all cellular processes. When cells need energy, ATP molecules are broken down, releasing energy that is used by the cells for the various tasks they perform. It is the main source of energy for the cells and is thus essential for all cellular functions.

Trophic efficiency is a measure of the efficiency of energy transfer between trophic levels, usually expressed as a percentage.

It is calculated by dividing the energy available at the next trophic level by the energy available at the current trophic level. The typical range of trophic efficiencies is between 10 and 20 percent, with an average of around 10-15 percent.

This means that only 10-15 percent of the energy available at one trophic level is transferred to the next level. This is due to the fact that energy is lost through metabolic processes and the fact that only a small portion of the energy consumed is passed up the food chain.

The remaining energy is lost as waste heat. Higher trophic efficiencies typically occur in more stable systems, such as marine ecosystems, where multiple trophic levels are present.

After the rabbit body cell has undergone mitosis, there will be 20 chromosomes in each rabbit body cell.

After a rabbit cell undergoes mitosis, the resulting daughter cells will have the same number of chromosomes as the parent cell. In this case, since each body cell in the new species of rabbit has 20 chromosomes, the daughter cells produced after mitosis will also have 20 chromosomes.

This is because mitosis is a process of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell.

During mitosis, the cell goes through a series of stages that separate the chromosomes into two identical sets, one for each daughter cell. This ensures that each daughter cell has a complete set of chromosomes that are identical to the parent cell.

Therefore, in this case, the number of chromosomes in a rabbit body cell after mitosis would remain constant at 20.

Explanation:

If gas molecules in an enclosed space are allowed to enter a second chamber, the resulting redistribution of gas molecules represents an increase in entropy. The entropy of an enclosed system tends to increase. This is due to the fact that in an isolated system, the level of disorder or randomness, referred to as entropy, tends to increase over time.

This means that the system's energy is distributed among the particles or molecules, leading to increased randomness and a reduction in the system's energy state.

The greater the number of gas molecules, the higher the entropy. As a result, when gas molecules are transferred from one chamber to another, the system's entropy increases. When the number of gas molecules in one chamber decreases, the entropy of the system in that chamber decreases as well. The system's overall entropy, on the other hand, increases because the gas molecules have been moved from one chamber to another, causing them to become more disordered.

The entropy of a system can also be calculated using the formula ΔS = Q/T. Where ΔS is the change in entropy, Q is the energy transferred, and T is the temperature in Kelvin. When a gas expands, it does work by moving a piston or expanding into a vacuum, and as a result, it loses energy. The change in energy can be calculated using the ideal gas law, PV=nRT.

Foraminifera are tiny marine animals that have been living for millions of years. Their shells are made up of calcium carbonate and are well-preserved in sediments. The shells of these microorganisms are widely used in paleoceanography to determine past climatic conditions. Paleoceanography is the study of the history of the oceans in the geological past using sediments and fossils. It helps us to understand how the oceans and climate have changed over time.

Paleotemperature is the measure of the temperature that existed in past geological ages. The temperature is determined by various means, including studying the growth rings of trees, ice cores, and microfossils, and others. Microfossils are microscopic fossils that are found in rocks and sediments that help in reconstructing past environmental and climatic conditions.

Oxygen isotope ratio is the measure of the relative abundance of oxygen isotopes 18O and 16O in a sample. The ratio of the two isotopes changes as a result of temperature changes. The ratio is used to reconstruct past temperature changes.
