Answer:

When placed in water, hydrophobic molecules tend to form a ball or cluster. The hydrophilic regions of the phospholipids tend to form hydrogen bonds with water and other polar molecules on both the exterior and interior of the cell.

The main consequence of this process is that the soil is removed by the force and pressure of the drilling.

For the extraction of oil from the land, the vegetation is removed that destroys the habitat of many organisms as well as the degradation of soil occurs due to the force and pressure of the drilling machines.

In water, the aquatic organisms including plants and animals are adversely affected due to this process of extraction so we can learn that there are many consequences of extracting oil from the soil to the surrounding environment..

An allele is best described as a version of a gene. Option A is correct answer.

Genes are segments of DNA that contain instructions for the development and functioning of living organisms. Each gene can exist in different forms, called alleles.

For example, let's consider a gene that determines eye color. This gene can have different alleles, such as brown allele, blue allele, and green allele. Each allele represents a different version or variant of the gene.

The different alleles of a gene can lead to variations in traits or characteristics. In the case of eye color, individuals with two copies of the brown allele will have brown eyes, individuals with two copies of the blue allele will have blue eyes, and individuals with one copy of the brown allele and one copy of the blue allele will have a mix of brown and blue eyes.

So, the correct answer is A. A version of a gene. An allele represents different versions of a gene that can result in variations in traits or characteristics.

Option A is correct answer

I can't really see it.

Explanation:

The factors that must remain the same in an experiment are known as control variables.

In order to conduct a proper experiment, there must be 3 kinds of variables. These are:

A dependent variable is a variable that the experiment seeks to observe, this variable is expected to change in value throughout the experiment and depends on other variables. An independent variable is one that the researcher changes throughout the experiment in order to see what effect it will have on the dependent variable.

The variables referred to in the question are control variables. Control variables are the factors that must remain constant in an experiment. This is to ensure that when we measure a change in the dependent variable, we know to attribute it to the correct cause of the change. The presence of control variables helps to ensure a valid experiment and limits the influence of other factors on the outcome.

Answer:

Bacteria converts ammonia into nitrites and nitrates that plants can use.

Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines.

Answer:

Sugars are particularly important fuel molecules, and they are oxidized in small steps to carbon dioxide and water.In this section we trace the major steps in the breakdown, or catabolism, of sugars and show how they produce ATP, NADH, and other activated carrier molecules in animal cells. We concentrate on glucose breakdown, since it dominates energy production in most animal cells. A very similar pathway also operates in plants, fungi, and many bacteria. Other molecules, such as fatty acids and proteins, can also serve as energy sources when they are funneled through appropriate enzymatic pathways.

Answer:

The nuclear lamina is an array of filaments on the inner side of the nuclear ... If a method were found that could cause the lamina to fall into disarray, ...

Explanation:

1. The nuclear lamina is a network inside the nucleus which maintain the shape of nucleus.

2. It is composed of intermediate filaments and many proteins.  

3. It providing mechanical support to the nucleus and play many other rolls in the cell.

4. In a cell  if the nuclear lamina fall into disarray, the nucleus is misshapen and all these processes run awry. Such cells in which nuclear lamina is broken, they tend to become senescent in response to internal dysfunction, and cause damage to surrounding tissue.

Mars and Venus are the planets of the solar system and vary in their temperatures. Mars has a thin atmosphere that cannot much amount of heat. Thus, option D is correct.

Mars has been the fourth planet of the solar system that is also called the red planet due to its red appearance. It has more amount of carbon dioxide than oxygen gas. It comprises various gases and has a thin atmosphere.

The thin atmosphere of Mars unlike Venus cannot hold the heat and transmits it back to space. Venus has a thick atmosphere that traps heat and results in an increased surface temperature. The atmospheric particle of Mars cannot retain heat and hence vary in temperature.

Therefore, option D. Mars has a lower temperature than Venus due to its thin atmosphere.

Answer:

when a cell creates hydrogen peroxide, it stores it inside the cell's specialized organelles, called peroxisomes, which contain hydrogen peroxide-busting catalase.

Explanation:

Hydrogen peroxide gets into the cell with the help of an enzyme called peroxide dismutase, which significantly catalyzes the process of dismutation of superoxide radicals in order to synthesize H2O2.

Hydrogen peroxide may be defined as a liquid chemical that typically contains hydrogen and oxygen and is generally utilized for bleaching and as an antiseptic.

Hydrogen peroxide is consistently produced in the cell and then stored in the organelle known as the peroxisome. The cells then eliminate the excess amount of hydrogen peroxide (H2O2) with the action of an enzyme called catalase. And gest dissociates into the water (H2O) and molecular oxygen (O2).

Therefore, the process of production and digestion of hydrogen peroxide in the cell is well described above.

For characteristic features of key stone species, option 1, 2 and 4 are correct.

The presence of the species whether plant or animal in an ecosystem largely influence on a given environment called as keystone species.

It affect the habitat of all living organisms, so that the ecosystem would become functionless in absence of keystone species.

On of the best example is prey-predator relationship.

Some important environmental influence of keystone species are, it affect organism's physical appearance.

There is an impact of parasites, diseases on prey and host population, act as a mutualist, absence of key stone species leads to domino effect.
