Answer: B) Leukopenia decreases the body's ability to fight infection.
The condition Leukopenia results due to decrease in the count of the white blood cells. It results typically due to the decrease in the number of neutrophil. White blood cells are important for maintaining the immunity within a human body. These cells protect the body against the foreign invaders like bacteria, viruses hence, prevents infection. As, the number of white blood cells decreases the body's ability to provide protection against foreign invaders decreases and hence, infection occurs.
Therefore, B) Leukopenia decreases the body's ability to fight infection is correct.
Leukopenia is a condition characterized by a decrease in white blood cells. Leukopenia decreases the body's ability to fight infection and the correct option is option B.
White blood cells, also known as leukocytes, play a crucial role in the body's immune response. They help identify and destroy foreign substances such as bacteria, viruses, and other pathogens. When a person has leukopenia, the reduced number of white blood cells means there are fewer immune cells available to defend against infections.
With a lower count of white blood cells, the body's ability to mount an effective immune response is compromised. It becomes more challenging to identify and eliminate invading pathogens, making the individual more susceptible to infections. Leukopenia can weaken the immune system, making it harder for the body to control and eradicate infections properly.
Thus, the ideal selection is option B.

b. The undergrowth of rainforests is choked by weeds and plants.
c. Rainforests are characterized by high levels of rainfall.
d. Not all rainforests are tropical rainforests.
Rainforests are responsible for most global oxygen turnover is not true concerning the rainforests.
Further Explanation:
Rainforests are dense jungle and considerably tall. They are referred to as rainforest because every year, high rainfall occurs in these areas. The climate in these forests is very humid and hot, so the plant and animal exist in these areas and are adapted to this environment. The normal temperature of these areas is 70 degree Celcius – 85 degree Celcius-. Many household items are obtained from these forests. Most of South Africa and western Africa has the largest rainforest. In India and Australia, smaller rainforests are present.
Rainforest provides numerous benefits such as maintain the climate, greenhouse effect and provide space for animals and plants. Also, they produce food and medicine for many organisms. They are not responsible for providing global oxygen because plant present in humid areas takes a higher amount of oxygen to fee vegetation.

Rainforests have a unique ecological structure where the dense canopy of trees filters out much of the sunlight, leading to limited light penetration on the forest floor. The correct answer is b. The undergrowth of rainforests is choked by weeds and plants.
As a result, the undergrowth of rainforests typically has limited vegetation due to the lack of sufficient light, rather than being choked by weeds and plants. The majority of plant life and diversity in rainforests is concentrated in the upper layers of the forest, such as the canopy and understory.
Rainforests are characterized by a dense canopy formed by tall trees that grow close together and have large, spreading branches. These trees create a thick layer of foliage that blocks much of the sunlight from reaching the forest floor. Consequently, the amount of available light in the understory, the lower layer of the forest, is significantly reduced.
Therefore, the correct answer is b. The undergrowth of rainforests is choked by weeds and plants.

A reaction coupled with the production of ATP
An oxidation reaction
The movement of chloride ions out of a cell by the CFTR receptor involves a reaction coupled with the hydrolysis of ATP.
Step 1: The CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) receptor utilizes active transport to move chloride ions out of a cell. This process involves a reaction coupled with the hydrolysis of ATP (adenosine triphosphate).
ATP is a molecule that stores and provides energy for cellular processes. In this context, ATP is used to fuel the active transport of chloride ions against their concentration gradient.
Step 2: Active transport mechanisms like the CFTR receptor require energy to move substances against their natural direction of movement. In this case, the hydrolysis of ATP provides the necessary energy for the movement of chloride ions out of the cell.
ATP is enzymatically broken down into ADP (adenosine diphosphate) and inorganic phosphate, releasing energy that drives the active transport process.
This coupling of the reaction with ATP hydrolysis ensures that the movement of chloride ions is achieved against the concentration gradient, maintaining cellular homeostasis and contributing to various physiological processes.
Understanding these cellular mechanisms is vital for comprehending how cells regulate ion concentrations and maintain proper functioning.

The CFTR receptor facilitates the active transport of chloride ions out of a cell, coupling this process with the hydrolysis of ATP. The correct option is A.
This means that as chloride ions are moved against their concentration gradient, the energy released from ATP hydrolysis powers the transport. This mechanism ensures efficient ion movement and is essential for maintaining proper ion balance in various tissues, such as the respiratory epithelia.
It's not an equilibrium process, as it requires constant energy input. Moreover, it's not a reduction or oxidation reaction, but rather a prime example of active transport coupled with ATP hydrolysis for cellular energy utilization. The correct option is A.

Further Explanation:
DNA means deoxyribonucleic acid. It can be referred to as the hereditary particle that can be found in every individual and all other organisms in the environment. DNA is usually located in the cell nucleus, and a very few amount are located in the mitochondria of living organisms.
It is important to note that series of information are stored in the DNA and the information is formed in four chemical bases:
More than 2 million bases can be found in the human DNA and more than 99% of those bases always the same in every individual.
The information gotten from an organism makes research easier for scientists in getting a rapid and efficient result. And due to the removal of DNA scientists are able to sequence genomes, detect viruses and bacteria in the environment.
