The motor nervous system is a system present in the brain to help animals to speak, move and breathe.

Motor neurons are cells in the brain and spinal cord that enable locomotion, speech, swallowing and breathing by sending commands from the brain to the muscles that perform these functions. Nerve fibers are the longest in the body, with single axons extending from the base of the spinal cord to the toes.

For motor functions, there are the oculomotor nerve, trochlear nerve, trigeminal mandibular nerve (V3), abducens nerve, facial nerve, glossopharyngeal nerve, vagus nerve, spinal nerve accessory muscle and N. hypoglossus muscle. These are the working of the motor nervous system.

option b is the answer. The best explanation for natural selection in the evolution of long necks in tortoises is that tortoises with longer necks survived because they were more fit for their environment.

This means that they were better able to reach food sources, especially during periods of drought or when resources were scarce. The ability to access food allowed them to grow stronger and reproduce more successfully, passing on their long-necked traits to their offspring. Over time, this led to a population of tortoises with longer necks, as those with shorter necks were not able to compete as effectively for resources and did not survive to pass on their genes. It is important to note that this process occurred gradually over many generations and was not the result of any intentional choice by the tortoises.

Primary meristematic tissue helps the plant increase in length or vertical growth, meaning it helps the plant grow up toward the sun and down into the soil.

"Accessory muscle use" is a sign of respiratory distress seen in the neck. Respiratory distress refers to the condition where the respiratory rate increases, and it becomes difficult to breathe. Accessory muscles are recruited to help with breathing when a person experiences respiratory distress.

Therefore, one of the signs of respiratory distress seen in the neck is accessory muscle use. This sign of respiratory distress is common among individuals with breathing problems such as asthma, COPD, bronchiolitis, and others. It is characterized by the movement of the neck muscles, sternocleidomastoid, and scalene muscles as a result of labored breathing or shortness of breath.

Respiratory distress is a life-threatening condition that requires immediate intervention. A person suffering from respiratory distress has difficulty in breathing, which could be due to a variety of factors. Some of the causes of respiratory distress include acute respiratory distress syndrome (ARDS), asthma, pneumonia, heart failure, and pulmonary embolism.

Accessory muscles refer to the secondary muscles used in breathing when the primary muscles are unable to perform their function. These muscles include the sternocleidomastoid, scalene muscles, and others. When a person experiences respiratory distress, the accessory muscles in the neck become active, causing visible movement in the neck muscles.

This movement is a sign of respiratory distress and indicates that the person is struggling to breathe. Respiratory distress is a medical emergency that requires immediate intervention. If you or someone you know experiences any signs of respiratory distress, such as accessory muscle use in the neck, seek medical attention immediately.

Explanation:

The land around you, no matter where you live, is made of rock. If you live in a place that has good rich soil, the soil itself is finely broken down or weathered rock.

People that live in a desert region can easily find rocks on the surface. These rocks lay on a surface of clay that is also a product of weathering rock. Weathering is the process of breaking down rocks and minerals into smaller pieces by water, wind, and ice.

Sedimentary rocks are formed from the breaking apart of other rocks (igneous, metamorphic, or sedimentary rocks) and the cementation, compaction and recrystallization of these broken pieces of rock.

Sedimentary rocks are formed from broken pieces of rocks. These broken pieces of rock are called sediments. The word "Sedimentary" comes from the root word "Sediment".

Sedimentary rocks are usually formed in water. Streams and rivers carry sediments in their current. When the current slows around a bend or the river empties into a lake, or ocean, or another river the sediments fall out because of gravity. The larger sediments fall out first and the lightest sediments fall out last.

The thing that can be said about the area is B. the area was once covered by a moving stream of water.

Conglomerate rocks refer to sedimentary rocks that are made of sand and rounded pebbles which are held together by calcite, silica, or iron oxide.

Since there is a rock field with lots of conglomerate rocks, this could be a result of weathering. In such a case, the area may be once covered by a moving stream of water which could have led to the rocks that were formed.

Answer:

The digestive tract of the earthworm and the salamander are similar in some ways, but they also have some differences. Both animals have a simple, linear digestive tract that consists of the mouth, esophagus, crop, gizzard, and intestine. However, the earthworm has a smaller and simpler digestive tract than the salamander.

One of the main differences between the digestive tracts of the earthworm and the salamander is the presence of glands. The salamander has several glands in its digestive tract, including the salivary glands, liver, and pancreas, which produce digestive enzymes and hormones that help to break down food and absorb nutrients. In contrast, the earthworm does not have any glands in its digestive tract, and it relies on the mechanical grinding action of its gizzard to break down food.

Another difference between the digestive tracts of the earthworm and the salamander is the presence of a stomach. The salamander has a muscular stomach that is used to store and churn food, which helps to break it down and mix it with digestive enzymes. The earthworm, on the other hand, does not have a stomach, and it does not have the ability to store food for extended periods of time.

Overall, the digestive tract of the earthworm is smaller and simpler than that of the salamander, and it lacks some of the specialized structures and functions that are found in the salamander's digestive tract.

Answer:

The cell shown in the image is haploid, which can be affirmed by the presence of an odd number of chromosomes.

Explanation:

Haploid cells are those that have a single set of chromosomes, that is, half of the chromosomal charge (n) of an organism. These cells correspond to gametes.

Diploid cells are those with complete chromosomal charge (2n) and correspond to somatic cells.

The cell shown in the image is a haploid cell, since it has only three chromosomes. Because diploid cells contain chromosomes in pairs, even if the haploid cell of that species is odd or pair, diploids will always have an pair number of chromosomes.

Answer:

The brown version of gene 1 is dominant over the blue one. Dominant means that if at least 1 of your two copies is brown (Bb), then you will have brown eyes. Geneticists represent the different versions of the eye colour gene as B for brown and b for blue (the capital letter is the dominant, the lowercase, recessive).

Explanation:

There will be a Tt genotype in the empty box. The PTC phenotype will serve as tasters as TT, Tt. Given that PTC is a dominant characteristic and is assumed to be a simple gene trait, the other genotype would be Tt. This means that at least one dominant "T" allele must be present in a genotype to produce the PTC taste phenotype. The only possible combination is "tt," which is not at all appealing.

Mendel identified three primary inheritance laws, which are as follows:

According to the law of segregation, each person has two copies of each gene—one from each parent—and these copies split during gamete creation. This indicates that each gene is only present in one copy in each gamete (egg or sperm).

The inheritance of one gene does not affect the inheritance of another gene, according to the law of independent assortment. In other words, individual features can be inherited independently of one another, and a child's combination of traits is determined by chance.

One allele can be expressed when two distinct variants of a gene (alleles) are present, according to the law of dominance.

The PTC gene's alleles control the substance's flavor. It has a prevailing quality. Those who can taste PTC have dominant TT alleles (Homozygous or Tt Heterozygous).

Recessive tt gene carriers are referred to as non-tasters.

PTC is going to taste bitter to those who have the dominant allele in their PTC gene.

Those who carry the recessive allele for the PTC gene describe the taste of PTC as bland.

Consequently, a person's taste is determined by their genetic makeup. Tasters or non-tasters might be the phenotype.

TT, Tt (tasters) (tasters)

tt ( non-tasters) ( non-tasters).
