Inputs:

- Sensory inputs from eyes, ears, skin, tongue etc which provide information about external environment and internal body states

Components:

- Nervous system (brain, spinal cord, nerves) which processes input and coordinates responses

- Endocrine system (glands) which secretes hormones to regulate processes

Outputs:

The system provides:

- Muscle movements and actions as output responses

- Gland secretions like tears, sweat and saliva as outputs

- Physiological changes in heartbeat, breathing and digestion as outputs

The overall operation is that inputs are detected, processed by the brain and nervous system, which then coordinate output responses via muscles, glands and organs to maintain homeostasis and adapt to the environment. The endocrine system assists the nervous system by secreting hormones that induce slower but longer-term responses.

Answer:C

Explanation:

The Sun will illuminate us for billions years whereas the rest of the answer choices can be exhausted and used up completely.

Solar Energy would best be categorized as inexhaustible. So, the correct option is (C).

Resources are divided as renewable or non-renewable. A renewable resource can renew itself at the rate it is used, while a non-renewable resource has a limited supply. Examples of renewable resources are timber, wind and solar while non-renewable resources are coal and natural gas.

Renewable energy is the energy which can be used repeatedly and it is renewed again after a short period of time which is defined as the type of energy resources that can be renewed naturally. Renewable sources of energy can replace the conventional sources of energy which produce harmful gases which are harmful as well as costly.

Non-renewable resources are those which cannot be reused or reproduced, it is used only once and takes a long time to reproduce. These are also not good for the environment. Burning fossil fuels harms our environment.

Thus, Solar Energy would best be categorized as inexhaustible. So, the correct option is (C).

The rumbling noise caused by the movement of gas in the intestine is known as stomach rumble.

A stomach rumble, additionally called a bowel sound or peristaltic sound, is a rumbling, growling or gurgling noise produced with the aid of using motion of the contents of the gastro-intestinal tract as they're propelled via the small gut with the aid of using a sequence of muscle contractions known as peristalsis. Your belly simply made a growling sound known as borborygmus. That's due to the fact while the muscle groups for your digestive device circulate food, liquid, and gas via your belly and small gut, it produces a rumbling sound.

A pedigree is able to support multiple inheritance patterns, and it is also possible that sex-linked dominant traits and autosomal dominant traits share similar pedigrees.

Genes on the X chromosome are altered to generate X-linked dominant traits. Fathers are unable to pass on X-linked qualities to their sons, which is a trait of X-linked inheritance.

Variants in genes on the X chromosome can also produce X-linked recessive diseases. Males have X-linked recessive diseases significantly more commonly than females since it is improbable that females will have two mutated copies of this gene.

Polygenic.

Explanation:

A trait that is controlled by more than one gene is called polygenic which translates to "multiple genes".

If the donor cells were not centrifuged and resuspended in lb broth in the transposon mutagenesis experiment, then the step of electroporation would directly be affected.

Electroporation is a process used to introduce foreign DNA into bacterial cells by applying a brief electrical pulse to a suspension of cells in the presence of the DNA. In this case, the transposon DNA is introduced into the donor cells through electroporation.

Without the centrifugation and resuspension step, the donor cells may not be properly prepared for electroporation. This step is crucial for ensuring that the cells are in optimal condition for the electrical pulse to effectively introduce the transposon DNA. If the cells are not properly resuspended, the electrical pulse may not be able to penetrate the cell membrane and deliver the transposon DNA. As a result, the mutagenesis would fail since the transposon would not be inserted into the genome of the bacterial cells.

The group of microorganisms that do not usually call the skin "home" are yeasts so the correct answer is option (D).Yeasts are a type of fungi that thrive in moist and warm environments. They are commonly found in areas such as the mouth, digestive tract, and genital area, but they are not typically found on the skin.

On the other hand, Escherichia, Cornyebacterium, and Propionibacterium are all examples of bacteria that are commonly found on the skin. Escherichia and Cornyebacterium are normal skin flora, while Propionibacterium can cause acne when it overgrows. It is important to note that while these bacteria are usually harmless, they can cause infections if they enter the body through a cut or wound. Therefore, it is important to maintain good hygiene and keep cuts and wounds clean to prevent infection.

However, yeasts are not a prominent component of the skin's normal microbiota. While they may occasionally be present on the skin, they do not typically establish a permanent or significant presence. Yeasts, such as Candida species, are more commonly associated with infections in moist areas of the body, such as the mouth, vagina, and gastrointestinal tract, rather than the skin.

In summary, among the options provided, yeasts do not usually call the skin "home," while bacteria like Escherichia, Cornyebacterium, and Propionibacterium are commonly found on the skin.

Minerals make up a significant amount of your body mass, about 60%. Minerals are essential nutrients that cannot be made in the body.

Minerals are inorganic compounds that are vital for the proper functioning of the human body. They play various roles, including serving as structural components, regulating bodily processes, and acting as cofactors for enzymatic reactions. Two correct statements about minerals are:

1. Minerals make up a significant amount of your body mass, about 60%: Minerals such as calcium, phosphorus, potassium, and magnesium are major components of bones, teeth, and bodily fluids. They contribute to the structural integrity and overall composition of the body.

2. Minerals are essential nutrients that cannot be made in the body: Unlike certain substances like glucose or certain vitamins, minerals cannot be synthesized by the body. They must be obtained from external sources such as food or supplements. Essential minerals include iron, zinc, copper, iodine, selenium, and others, which are required in trace amounts for various physiological functions.

Minerals are essential for numerous bodily processes, including the formation of bones and teeth, maintaining proper nerve function, regulating fluid balance, and facilitating enzymatic reactions. They are classified into two categories: major minerals, required in larger amounts, and trace minerals, required in smaller amounts. Adequate intake of minerals through a balanced diet is crucial for overall health and well-being.

While monogamy may be a contributing factor, the absence of a baculum in humans is likely a complex result of a combination of factors, and may simply be a byproduct of evolutionary history.

The lack of a baculum in humans is likely due to a combination of factors. While monogamy may play a role in reducing the need for a baculum, it is important to note that not all monogamous species lack a baculum. Additionally, humans have evolved a number of other adaptations for reproductive success, such as increased brain size for social and cognitive abilities, and a prolonged period of infant dependency.
It is also possible that the absence of a baculum in humans is simply a result of genetic drift or historical accident. Evolution does not always result in the most efficient or optimal solution, but rather what is sufficient for survival and reproduction in a given environment. In the case of humans, the absence of a baculum may have simply not posed a significant disadvantage to reproductive success, and thus was not selected for or against.

An individual whose genotype is homozygous for the dominant allele has two copies of the allele that determines phenotype whenever the allele is present.

An individual whose genotype is homozygous for the dominant allele has:

a. Two copies of the allele that determines phenotype whenever the allele is present.

In genetics, the terms "dominant" and "recessive" are used to describe the relationship between different alleles of a gene. If one allele is dominant over another, it means that the presence of just one copy of the dominant allele is sufficient to determine the phenotype (observable trait) associated with that allele.

When an individual is homozygous for the dominant allele, it means that they have two identical copies of the dominant allele. Since the dominant allele determines the phenotype whenever it is present, having two copies of the dominant allele ensures that the phenotype associated with that allele will be expressed.

In contrast, the recessive allele, which is not expressed when the dominant allele is present, would not be present in an individual who is homozygous for the dominant allele. Therefore, option a. "Two copies of the allele that determines phenotype whenever the allele is present" is the correct choice.
