The truth about these two brothers that have brown eyes is they have the same phenotype (Brown) but different genotypes (BB and Bb). So, the correct option is C.

Genotypes may be defined as a given set of alleles that an individual possesses. They are ultimate combinations of alleles.

In this situation, the allele B is dominant over the allele b, therefore, in both cases, phenotypes remain the same i.e. Brown eyes, but the genotypes differ. This defines how an allele interacts with another allele and changes the genotype.

Therefore, the truth about these two brothers that have brown eyes is they have the same phenotype (Brown) but different genotypes (BB and Bb).

Water Pollution is any physical, biological, or chemical change in water quality that adversely affects living organism or makes water unsuitable for desired uses.

Answer:

A) the different humidity

The water table is at the surface of the Earth in humid areas, but it can be tens to hundreds of metres or more below the surface in arid areas.

Water that is found underground in saturated regions beneath the surface of the earth is known as groundwater.

The water table is the term for the saturated zone's upper surface. Contrary to popular perception, underground rivers are not created by groundwater.

In humid regions, the water table is at the surface of the planet; but, in arid regions, it can be tens to hundreds of metres or more below the surface.

Arizona's water usage is currently lower than it was in 1957 thanks to improved conservation practises and a decline in irrigation water use.

Since the beginning of our state's history, Arizona has never required municipal or residential restrictions on uses, even though we have five times (5x) as much water stored as we consume.

Thus, the groundwater Supply differ from a dry hot area like Arizona to a cooler moist area like Oregon.

Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.

The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

Wich because oxygen and carbohydrates are produced during photosynthesis.

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds, such as glucose. During photosynthesis, carbon dioxide and water are used as inputs, and oxygen and glucose are produced as outputs. The process occurs in specialized organelles called chloroplasts, which contain pigments such as chlorophyll that capture light energy. This energy is then used to power the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Proteins are important macromolecules composed of amino acids with a wide range of functions. There are different functions of proteins; however, the three typical functions of proteins are support, acting as enzymes, and regulating hormones. Let's see how these three functions play out below:

The support function of proteins is quite essential. Proteins serve as structural components of cells and tissues. Proteins provide support to cells and tissues in various forms, such as collagen and elastin in connective tissue, keratin in nails and hair, and actin and myosin in muscle.

An enzyme is a type of protein that acts as a catalyst for metabolic reactions in cells. Without enzymes, biochemical reactions would not occur at the rate that allows life to be sustained. Enzymes work by bringing reactants together and providing the right environment for reactions to take place. Without enzymes, biochemical reactions would not occur at the rate that allows life to be sustained.

Regulatory hormonesProtein hormones, or polypeptide hormones, are hormones whose molecules are made of peptides. Protein hormones are typically synthesized and secreted by endocrine cells in response to stimuli such as body fluids and food. Some examples of protein hormones include insulin, glucagon, prolactin, and growth hormone. These hormones work to regulate physiological processes within the body. They work by binding to specific receptors in cells, which then trigger a series of signaling events that result in various physiological responses.

Sensorineural hearing loss may be related to gradual nerve degeneration.

Sensorineural hearing loss is a type of hearing loss that occurs due to damage to the inner ear or the auditory nerve that transmits sound from the inner ear to the brain. This type of hearing loss is usually permanent and cannot be corrected with medications or surgery.

Gradual nerve degeneration is one of the most common causes of sensorineural hearing loss. It occurs when the hair cells in the inner ear, which are responsible for transmitting sound signals to the auditory nerve, become damaged or die off over time.

This can be caused by a variety of factors, such as aging, exposure to loud noises, certain medications, and diseases such as Meniere's disease.

Foreign bodies, perforated tympanic membrane, and impacted cerumen (earwax) are more likely to cause conductive hearing loss, which occurs when sound waves are blocked or cannot be transmitted effectively through the outer or middle ear.

This type of hearing loss can often be corrected with medications, surgery, or the removal of the foreign body or impacted cerumen.

A baroreceptor is a special nerve ending that allows your brain to sense blood flow and blood pressure in the most of blood vessels of your circulatory system.

The circulatory system is the big network of blood vessels, as well as veins, which bring blood from all over your body back to the lungs, and arteries, which send blood from the lungs to your other cells and organs.

Blood pressure is the total amount of force blood adept on the vein or artery in which it is traveling.

The more the blood pressure in a particular blood vessel, the higher blood is traveling through that vessel to the organs that the vessel innervates.

Information about blood pressure and blood flow is needed in the brain so that accommodation can be made whenever required.

Brief stimuli were conveyed to the carotid chemoreceptors or baroreceptors in dogs anesthetized with pentobarbitone or chloralose.

Chemoreceptor stimulation was achieved by swift retrograde injections of 0-2-0-5 ml. heated, CO2-equilibrated saline through a cannula in the external carotid artery. Baroreceptor stimulation was achieved by driving retrograde injection of 2-5 ml.

Cross between pink and white fruit produce the offsprings of genotype  Rr Rr rr rr and phenotype as 2 pink fruit and 2 white fruit.

The phenotype of a heterozygous dominant person is a mixture of dominant and recessive traits when none of the characteristics of a gene are dominant. We referred to this as incomplete dominance. For illustration, the Mirabilis jalapa's blossom colour. The white flower has a recessive nature while the red flower has a totally dominant personality.

F1 generation:

RR X rr => cross between red and white fruit

Progeny  => Rr Rr Rr Rr  => all four progeny are pink fruit

This happens due to incomplete dominance.

F2 Generation :

Rr x rr => Cross between pink and white fruit

Progeny => Rr Rr rr rr   => genotype

          Phenotype => 2 pink fruit and 2 white fruit.

In terms of genetics, codominance is a sort of inheritance in which 2 different expressions (alleles) of the same gene result in distinct traits in a person.
