Answer:

The myelin sheath is made from glial cells. Specifically, it is made from two types of glial cells: oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS). These cells wrap around the axons of neurons to create the myelin sheath, which acts as an insulator and helps to speed up the transmission of nerve impulses.

Explanation:

The myelin sheath, a crucial component for rapid and efficient signal transmission in the nervous system, is composed of glial cells, not axons, terminal buttons, or somas.

The myelin sheath is a fatty insulating layer that surrounds the axons of many nerve cells. It's not made of axons, terminal buttons, or somas, but rather, it's primarily composed of glial cells. Glial cells wrap around the axon of a neuron, creating a myelin sheath that accelerates the speed at which electrical signals, or impulses, pass along the axon. This myelination process is crucial for efficient and rapid transmission of signals across the nervous system. A neuron's terminal buttons, on the other hand, are located at the ends of the axon and are involved in releasing neurotransmitters, facilitating communication with other neurons.

Answer:

Due to difference in volume of both atmosphere.

Explanation:

There is difference in volume of carbondioxide and oxygen gas between the atmosphere and  the exhaled air because of the volume difference of atmosphere and exhaled air. The volume of atmosphere is larger than the body from where the gases are exhaled. The body has lower space for these gases so these gases are less in concentration in the exhaled air which the body releases as compared to the atmosphere where the concentration of these gases are larger.

The energy pyramid demonstrate a great amount of energy is lost traveling up the energy pyramid.

The energy pyramid demonstrates that as you move up from the producers (bottom level), which convert sunlight into energy through photosynthesis, to the primary consumers (herbivores), to the secondary consumers (carnivores that eat herbivores), and finally to the tertiary consumers (carnivores that eat other carnivores), there is a decrease in available energy.

This is because energy is lost at each level through processes such as respiration, heat loss, and waste. Therefore, the top predators of an ecosystem have access to the least amount of energy.

Diffusion occurs as a result of the natural tendency of particles to move from an area of high concentration to an area of low concentration (seen in cell) . It is driven by the principle of maximizing entropy, which is a measure of the randomness or disorder in a system.

Diffusion is a fundamental process that occurs in various biological, physical, and chemical systems. It plays a crucial role in various biological processes, such as the exchange of gases in the lungs (oxygen entering the bloodstream and carbon dioxide exiting), the movement of nutrients and waste products across cell membranes, and the distribution of signaling molecules within organisms.

Explanation:

The statement that best explains how one offspring was born with white fur is that the allele for black fur is dominant over the allele for white fur.

Offspring may be defined as the resulted progeny which is produced after the successful mating between male and female.

In the given scenario, the allele for black fur is dominant (B) over the allele for white fur (w). The Genotypes of male and female are heterozygous, i.e. Bb. When Bb is crossed with Bb, the resulted offspring have the genotypes BB, Bb, Bb, and bb. Out of which, the first three have black fur and the last have white fur.

Therefore, the statement that best explains how one offspring was born with white fur is that the allele for black fur is dominant over the allele for white fur.

Population - Group of one type of organism (ex. 15 bees)

Community - Group of multiple types of organism (15 bees, 10 birds, 11 ants)

Ecosystem - Community and abiotic thing interacting (sun and animals), interacting means changing of energy from predator to prey because things get eaten

Explanation:

The amount of mercury in each organism is going to be ten times greater than that in the organism below it because each organism in the food chain consumes ten times its own weight in food. Therefore, the following formula can be used to determine the amount of mercury in each organism:

Therefore, one tuna would contain 10,000 grams, or 10 kilograms, of mercury. When we convert this to grams, we obtain:

10 kg = 10,000 g

By multiplying by the 0.0022 conversion factor, we obtain:

10,000 g times 0.0022 equals 22 grams

Therefore, a person would ingest 22 grams of mercury from eating one tuna.

Answer:

.

Explanation:

Answer:

Roots have specialized cells called root hair cells that are responsible for absorbing water and mineral ions like nitrates from the soil. These cells have long thin projections that stick out into the soil.

For plants to take up mineral ions, ions are moved into root hairs, where they are in a higher concentration than in the dilute solutions in the soil. This movement of ions from a low concentration in the soil to a higher concentration in the plant is achieved through a process called active transport. Active transport is a process that is required to move molecules against a concentration gradient. This means that substances are moved from a low concentration to a high concentration, which is the opposite of what would happen naturally. The process requires energy.

In the case of root hair cells absorbing nitrate ions from soils with low nitrate concentrations, active transport allows the plant to take in the ions it needs from the soil around it. The energy required for this process is produced by respiration.

Answer:

crossing over

Explanation:

During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.

Genetic variation can occur during meiosis because of the process of crossing over.

Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes one from the mother and one from the father line up, parts of the chromosome can be switched.

Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place. It occurs at the pachytene stage of prophase I of meiosis.

During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.

The somatic nervous system can change the actions of its targets, the skeletal muscle fibers since its signals connect to receptor proteins in muscles. Option B.

Together with the autonomic nervous system, the somatic nervous system makes up the peripheral nervous system. Its function is to regulate the contractions of skeletal muscles, indicating that this neural system is controlled voluntarily (unlike the autonomic which is the involuntary nervous system).

The somatic system is composed of two main types of nerves: motor nerves, also known as efferent nerves, and sensory nerves, sometimes known as afferent nerves, which transfer information from the central nervous system (CNS) to the effectors (skeletal muscles).

The moderator band is found on the right side of the heart. So the statement is false.

The moderator band or septomarginal trabeculae is a band of muscular arches in the right ventricle that extends from the interventricular septum to the anterior papillary muscle. This muscle helps the papillary muscles carry out their functions, as well as facilitate and coordinate the transmission of electrical impulses for cardiac contraction. Moderator bands are frequently used by radiologists and obstetricians to more easily identify the right ventricle in prenatal ultrasonography. Leonardo Da Vinci was the one who described the ventricles as moderator bands in his exploration of human anatomy.
