Explanation:

The chemical messengers present in the body are known as neurotransmitters. These are the chemicals that the nervous system uses to send and receive information between neurons and muscles. A neurotransmitter can have one of three effects on a neuron:

Excitatory effect, Inhibitory effect, and/or Modulatory effect.

The list of neurotransmitters and their roles are as follows:

Glutamate: This is present in amino acid compounds which are located in the synapses. It functions as an excitatory neurotransmitter, causing neurons to discharge instructions when stimulated in the central nervous system.

Adrenaline: It helps to respond to body's psychological stress and protection mechanism. They are positioned above the kidney and are created by the adrenal glands. They operate throughout the central nervous system and swiftly increase your heart rate and provide oxygen to your muscles.

Serotonin: Serotonin is a crucial brain neurotransmitter that also has a role in the small intestine. In your digestive tract, serotonin increases feelings of contentment after eating and controls your appetite. When you eat anything that doesn't agree with your stomach, serotonin assists your body in getting rid of it.

Answer:

you gotta put the small "b" for the female and all the the box will be "Bb"

The dominant allele (black fur) has alleles B and b for the recessive allele (white fur), so the offspring will all have bodies with black fur.

Phenotype is the physical appearance of characters which is the result of genes which express in the cell to give a particular trait in the diagram black is dominant over white so all the offspring show a black phenotype.

Male genotype: BB

Female genotype: bb

Cross: BB X bb

Gametes: B, B, b, b

All progeny will be black having genotype Bb, Bb, Bb, Bb.

The Cross is uploaded in the image below.

Genotype is the genetic appearance of the allele which shows the gene is responsible for a particular trait.

Therefore, the dominant allele (black fur) having allele B and b for the recessive allele is crossed, and all progeny will be black having genotype Bb, Bb, Bb, Bb.

Answer:

Simply put, the property of electron affinity refers to the relative amount of love that a material has for electrons. If atoms of a material have a high electron affinity, then that material will have a relatively high love for electrons. This property of electron affinity will be of utmost importance as we explore one of the most common methods of charging - triboelectic charging, also known as charging by friction or rubbing.

Suppose that a rubber balloon is rubbed with a sample of animal fur. During the rubbing process, the atoms of the rubber are forced into close proximity with the atoms of the animal fur. The electron clouds of the two types of atoms are pressed together and are brought closer to the nuclei of the other atoms. The protons in the atoms of one material begin to interact with the electrons present on the other material

Answer:

Social behavior is defined as interactions among individuals, normally within the same species, that are usually beneficial to one or more of the individuals. It is believed that social behavior evolved because it was beneficial to those who engaged in it, which means that these individuals were more likely to survive and reproduce. Social behavior serves many purposes and is exhibited by an extraordinary wide variety of animals, including invertebrates, fish, birds, and mammals.

Social behavior seems to provide many benefits to those who practice it. Studies have shown that many animals are more successful in finding food if they search as a group. This is especially true if food resources are clumped together only in certain places. If more individuals are cooperating in the search, there is a greater chance one of them will find the clump of food. In some cases, foraging in a group makes it easier to capture a prey. Dolphins are known to surround a school of fish and to take turns darting into the center to eat the fish that are trapped in the middle. Many carnivores will band together when they try to capture large prey. Some examples are that  wolves will hunt together when hunting moose, and lions will hunt together when hunting large prey such as wildebeests. When these animals are hunting much smaller prey, they will often hunt singly.

Many animals live in social groups partly for protection. Although one baboon might not be able to fight off a leopard, a troop of baboons often is able to do so. In addition, with more individuals cooperating together, some can serve as sentries looking for danger while the other group members are eating or sleeping. Prairie dogs and large flocks of crows normally have some individuals acting as sentries, which makes it nearly impossible to sneak up on a prairie dog town or a flock of crows.

Some animals form social groups to make travel easier. Canada geese and other bird species typically fly in a V formation. Just like bicyclists who ride behind one another in order to reduce wind resistance, the geese fly in formation to reduce the wind they must encounter. In this situation, the lead bird has the most tiring job, which is why several birds usually take turns leading the V. Some animals congregate in close proximity to one another in cold weather in an effort to stay warm. Small birds are sometimes known to huddle so closely they form a single large ball of birds.

Answer:

The emulsification of fat occurs in the liver.

Answer:

Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

Explanation:

Answer:

1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body.

Answer:

Es posible que Juan sospeche que no está alimentándose correctamente (comer en grandes cantidades no significa estar bien alimentado)

Explanation:

Las proteínas representan un macronutriente esencial que debe ser consumido a través de la dieta para crecer en masa muscular y también para mantener la masa de los músculos. Las proteínas están compuestas por muchos tipos diferentes de aminoácidos (los bloques de construcción de las proteínas), pero solamente 20 aminoácidos conforman las proteínas que se encuentran en el cuerpo humano. Los aminoácidos esenciales son aquellos que el cuerpo no puede sintetizar por sí solo. Estos aminoácidos esenciales son: histidina, fenilalanina, treonina, lisina, metionina, triptófano, valina, isoleucina y leucina. El consumo diario recomendado por la Organización Mundial de la Salud (OMS) de proteínas en un hombre adulto es 0,8 a 1 gramo por kilogramo de peso corporal. Además, es posible que el cansancio que experimenta Juan se deba a alguna deficiencia en micronutrientes esenciales, es decir, debido a la falta de vitaminas y minerales, los cuales también deben ser consumidos a través de la dieta. Por ejemplo, la fatiga puede deberse a la falta de hierro, un mineral fundamental cuya deficiencia lleva a cuadros severos de anemia. Similarmente, la deficiencia en vitamina D puede también causar agotamiento o fatiga crónica, entre otros síntomas (por ej., abruptos cambios en el estado de ánimo, debilidad ósea en los huesos, daño en el estómago, etc). Por otra parte, es importante remarcar que no se debe descartar la posibilidad de que el cansancio experimentado por Juan se deba a un cuadro de estrés y/o algún otro tipo de problema de salud, siendo por lo tanto necesario una descripción más detallada del cuadro clínico para obtener una conclusión más precisa de su situación.
