Explanation:

The given statement "decibel is a measurement of the amount of pollution" is False because Decibel is a unit of measurement for describing the ratio of two physical quantities, often acoustic or electric power, or for quantifying the relative loudness of sounds..

A decibel (dB) is a unit of measurement used to express the intensity or level of sound, not pollution. It is a logarithmic scale that compares the intensity of a sound to a reference level, typically the threshold of human hearing. The higher the decibel level, the louder the sound.

Pollution, on the other hand, refers to the presence or introduction into the environment of substances or energy that cause harm or discomfort to living organisms. Pollution can take many forms, such as air pollution, water pollution, and soil pollution, and is typically measured using different units of measurement depending on the type of pollution.

Therefore, while decibels can be used to measure the intensity of noise pollution, they are not a direct measure of pollution itself.

The only cranial nerve involved in sensory cutaneous (skin) innervation is the trigeminal nerve (cranial nerve V).

The only cranial nerve involved in sensory cutaneous (skin) innervation is the trigeminal nerve (cranial nerve V).

The trigeminal nerve is the fifth cranial nerve and is responsible for conveying sensory information from the face, scalp, and mucous membranes of the head.

It has three main branches: the ophthalmic branch (V1), the maxillary branch (V2), and the mandibular branch (V3). Each branch innervates specific regions of the face and head.

The ophthalmic branch (V1) provides sensory innervation to the forehead, upper eyelid, and front part of the scalp.

The maxillary branch (V2) supplies sensation to the lower eyelid, upper lip, cheek, and side of the nose. The mandibular branch (V3) innervates the lower lip, chin, lower jaw, and parts of the temporal region.

Through these branches, the trigeminal nerve enables the perception of touch, pain, temperature, and other sensory information from the skin of the face and head.

It plays a crucial role in facial sensation and is responsible for transmitting sensory input from these areas to the brain for interpretation.

Explanation:

If HIV is left untreated, the body's immune system is weakened by the virus and is no longer able to effectively fight off the infection, so the number of antibodies the body produces gradually declines.

Antibodies are proteins produced by the body's immune system in response to the presence of foreign substances called antigens. Antibodies work to identify and neutralize antigens such as toxins, bacteria, and viruses. They are essential in the body's defense against disease because they bind to antigens and mark them for destruction by other components of the immune system. Antibodies can also activate certain components of the immune system. B. Complement proteins that help destroy more foreign bodies

This is because the virus attacks and destroys the body's CD4 cells, which are important for the immune system, making it difficult for antibodies to form. Therefore, it is important to treat HIV as early as possible to avoid long-term damage to the immune system.

There is an important relationship among  homeostasis, defective mitochondria, and the  symptoms caused by LHON.

Explanation:

There is a great relationship among  homeostasis, defective mitochondria and the  symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.

The relationship among homeostasis, defective mitochondria and the symptoms caused by LHON is the following:

The power center of the cell, the mitochondria are also involved in homeostasis, the maintenance of a stable internal environment even in the face of variations in the external environment.

Mitochondrial diseases can be caused by inherited mutations in mitochondrial DNA or defects in the proteins responsible for regulating mitochondrial division, affecting the body's homeostasis.

Therefore, we can conclude that LHON is a disease associated with a mutation in the mitochondrial genome affecting the body's homeostasis.

Answer:

Net photosynthesis- 3mm/20min- 1.5mm/10min

Cellular respiration- 1mm/15min- 0.66mm/10min

Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)

Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr

As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).

Explanation:

Greenhouse gases are gases in the Earth's atmosphere that trap the sun's radiation and create a warming effect on the planet. Carbon dioxide is one of the most significant greenhouse gases and is released into the atmosphere through a number of sources.

Carbon dioxide enters the atmosphere from burning fossil fuels for energy, from deforestation and agricultural activities such as burning forests and croplands, and from other human activities. Carbon dioxide is also released through natural processes like respiration and volcanic eruptions.

When carbon dioxide is released into the atmosphere, it traps heat, leading to a rise in temperatures and contributing to climate change. Sort of like a blanket of warmth surrounding the Earth. This is why reducing emissions from burning fossil fuels and reducing deforestation is essential for reducing the amount of carbon dioxide entering the atmosphere.

The allele frequency of the A allele in this population is 40%.

To determine the allele frequency of the A allele in the population, we need to first understand the genetics of the population. In this case, we are given the frequencies of the three genotypes: homozygous recessive (aa) = 36%, heterozygous (Aa) = 26%, and homozygous dominant (AA) = the rest of the population.

The frequency of the aa genotype represents the frequency of the recessive a allele in the population. Since aa is a homozygous recessive genotype, it means that both alleles in an individual are a. Therefore, the frequency of the a allele can be calculated as the square root of the frequency of the aa genotype:

square root of 0.36 = 0.6

This means that the frequency of the a allele in the population is 60%.

To find the frequency of the A allele, we can subtract the frequency of the a allele from 100%:

100% - 60% = 40%

The conversion of 8 H₂O molecules to 2 H₂O molecules is a chemical change that occurs through a dehydration or condensation reaction. This process involves the removal of water molecules to form a larger molecule and requires energy to occur.

This is a reaction that occurs between two molecules, and results in the formation of a single, larger molecule, while releasing a small molecule, usually water. In this case, the small molecule is water (H₂O), hence the name dehydration or condensation reaction.
During this reaction, the 8 H₂O molecules combine to form 4 H₂O molecules. This reaction is often used in the laboratory to create polymers from monomers. It can also be used to produce certain biomolecules such as carbohydrates, proteins, and nucleic acids, as well as other chemical compounds.
In order to carry out this reaction, energy is required. The reaction occurs in several steps and involves the removal of water molecules from the original 8 H₂O molecules, forming a new, larger molecule. The reaction is reversible, which means that it can be carried out in both directions, depending on the conditions and reactants involved. Thus, the conversion of 8 H₂O molecules to 2 H₂O molecules is a chemical change that can occur through a process known as dehydration or condensation reaction.
