True or false environmentalism is study of how the natural world works how our environment affects us and how we affect our environment

The benthic sediment with the lowest percentage of organic matter would likely be open ocean deep sea sediments.

Open ocean deep sea sediments, as mentioned in option B, generally have the lowest percentage of organic matter compared to the other listed sediment types. This is because open ocean environments are characterized by low primary productivity, meaning there is a limited supply of organic material sinking to the seafloor. In these areas, nutrient availability is typically low, and the rate of organic matter deposition is slow. As a result, the sediments that accumulate over time contain a lower percentage of organic matter.

On the other hand, sediments in temperate deep sea regions (option A), deep sea regions beneath the equator (option C), abyssal sediments beneath gyre centers (option D), and sediments on the shelf-slope break (option E) may have higher percentages of organic matter. These areas often receive higher inputs of organic material due to factors such as increased primary productivity, nutrient availability, or proximity to landmasses where terrestrial runoff contributes organic matter to the marine environment.

Explanation:

Answer:

Put both objects on a desk

Explanation:

The best way to use the materials to investigate the force of gravity would be to put both objects on a desk. The force of gravity can thus be obtained by measuring the distance between the objects as well as their masses.

According to Newton's law of universal gravitation, the force of gravity (F) between two objects is directly proportional to the product of their masses (m and M) and inversely proportional to the square of the distance (d) separating them.

Mathematically,

     F = G \(\frac{mM}{d^2}\) where G is a constant.

The body composition assessment method that involves the estimation of the 3-dimensional volume of the body through measurement of an individual’s body weight while they are completely submerged under water is Hydrodensitometry.

Hydrodensitometry is based upon the Archimedes principle. It provides information of two components:  the fat mass and the fat-free mass. It is also called under-water weighing. This technique is not commonly used, however it is mostly used on athletes.

Body composition assessment is the method to calculate the ratio of fat-to-fat free mass. The composition if assessed to gain knowledge about the fitness of the body.

True. DNA photolyase, in the presence of visible light, can repair DNA damage due to ultraviolet radiation. This enzyme recognizes and binds to damaged DNA, absorbs energy from visible light, and uses it to repair the damage, specifically cyclobutane pyrimidine dimers caused by UV exposure.

DNA repair enzymes known as photolyases are responsible for repairing damage caused by ultraviolet light. Both the actual DNA repair and these enzymes' own activation require visible light. Photoreactivation is the process by which photolyases repair DNA.

DNA photolyases (photoreactivating compounds) convert the energy of light close to UV to noticeable frequencies into synthetic energy to break the cyclobutane ring of pyrimidine dimers in DNA and consequently forestall the deadly and mutagenic impacts of far UV (200-300 nm).

The lack of response could result from this species of mice having genetic differences that prevent their Hormone .

The lack of reaction could be caused by genetic variations in this kind of mice that prohibit their Hormone.

What contributes to genetic variations?

Gene variants, sometimes known as mutations, can cause genetic differences, or a normal process in which genetic information is rearranged as a cell prepares to divide can also cause genetic variations (known as genetic recombination). Different phenotypes can be introduced into an organism by genetic changes that change gene.

When an amoeba eats another unicellular organism, the membrane of the amoeba plays a crucial role in the process.

The first step is the amoeba extending its pseudopodia (false feet) towards the prey, which is usually a smaller unicellular organism such as a bacteria or a protozoan. The pseudopodia engulf the prey and bring it into contact with the plasma membrane of the amoeba.

Once the prey is in contact with the amoeba's plasma membrane, the membrane begins to engulf the prey by forming a small invagination, or "pocket" in the membrane. This invagination eventually surrounds the prey, forming a membrane-bound vesicle called a food vacuole.

Once the prey is inside the food vacuole, enzymes are released from lysosomes, which are organelles within the amoeba, to break down the prey's cell wall and membrane. The broken down materials are then absorbed into the amoeba.

The food vacuole then fuses with the plasma membrane, expelling the undigested material out of the amoeba. This process is called endocytosis and it is used by many cells to take in materials from the environment.

In all, the membrane of an amoeba acts as a selective barrier that allows the amoeba to engulf and digest prey while keeping its own contents separate. Additionally, the membrane allows the amoeba to use endocytosis in order to take in nutrients from its environment.

new species can form through allopatric or sympatric speciation. the mechanisms of genetic drift will act more strongly on populations that are initially separated in allopatry than on those initially separated in sympatry.

In a population, genetic drift refers to a shift brought on by chance in the frequency of an already present gene variant. Gene variations could completely vanish due to genetic drift, which would limit genetic diversity. Furthermore, it may lead to the widespread spread and even fixation of previously rare alleles.

The term "genetic drift" refers to haphazard changes in the population's gene variation frequency. Genetic drift occurs throughout time when the frequency of different alleles, or variable forms of a gene, fluctuates randomly. Allele frequencies are changed to account for these variations in allele presence.

Explanation:

Answer: The answer is Mitosis

Explanation:

Carbon from glucose is essential for the formation of amino acids the process which is responsible for the production of glucose in plants is photosynthesis.

Photosynthesis is the process by which plants or other organisms transforms light energy into chemical energy. During the process of photosynthesis, plants need three basic things to live: water, sunlight and carbon dioxide.

Photosynthesis is the process by which a plant produces its food using energy from sunlight, carbon dioxide from the air and water from the soil. The word photosynthesis can be separated to make two smaller words: ‘photo’ which means light ‘synthesis’ which means putting together

In this process, light energy from the Sun is absorbed by the green substance, called chlorophyll, present in leaves. This energy allows the production of glucose (food) by the reaction between carbon dioxide and water. Oxygen is also produced as a by-product.
