The hormone ________ signals feelings of fullness to the brain.
Answer:
leptin
Explanation:
Another hormone, Leptin, produced by fat cells, is an Adiposity signal that communicates with the brain about long-range needs and satiety, based on the body's energy stores. Research suggests that Leptin amplifies the CCK signals, to enhance the feeling of fullness
Why do dogs respond to higher pitched voices?
Answer: A high-pitched, singsongy vocalization means that an animal is non-threatening, peaceful or empathetic. Dogs even employ a higher pitch with us when they're trying to get the same message across, like when they whine when they see their owner.

what are the differences between plant cell and animal cell
Explanation:
Plant cell:
It is found only in plants.
It consists of cell wall.
Animal cell:
It is found only in animals.
It does not consists of cell wall.
Answer:
The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Chloroplasts
In animal cells, the mitochondria produces the majority of the cells energy from food. Plant cells use sunlight as their energy source; the sunlight must be converted into energy in a process called photosynthesis. Chloroplasts are perform this function. The energy conversion in plants is a complex set of reactions similar to those performed by mitochondria in animals
The Cell Wall
Another structural difference between in plant cells is the presence of a rigid cell wall surrounding the cell membrane. The tough wall gives added stability and protection to the plant cell. If you think about it, most animal cells are inside an organism that has either an exoskeleton or an endoskeleton, built in structure. Plants don't have a skeleton of any kind so the cells have to perform this.
Vacuoles
Vacuoles are large, liquid-filled organelles found only in plant cells. Vacuoles can occupy up to 90% of a cell's volume and have a single membrane. Their main function is as a space-filler in the cell, but they can also fill digestive functions and their interiors can be used as storage for nutrients.
Both plant and animal cells comprise membrane-bound organelles, such as endoplasmic reticulum, mitochondria, the nucleus, Golgi apparatus, peroxisomes, lysosomes. They also have similar membranes, such as cytoskeletal elements and cytosol. The plant cell can also be larger than the animal cell. The normal range of the animal cell varies from about 10 – 30 micrometres and that of plant cell range between 10 – 100 micrometres.

Which is included in a lysogenic cycle? early lysis of the host cell the creation and assembly of viral particles the appearance of viral infection symptoms a period of genetic integration
The lysogenic cycle includes the early lysis of the host cell that involves the incorporation of the viral genome into the host cell genome.
What do you mean by the Lysogenic cycle?
A lysogenic cycle may be defined as a method by which a virus can replicate its DNA using a host cell.
In the lysogenic cycle, the viral DNA gets integrated into the host's DNA but viral genes are not expressed. Lysogeny is characterized by the integration of the bacteriophage nucleic acid into the host bacterium's genome.
Therefore, the lysogenic cycle includes the early lysis of the host cell that involves the incorporation of the viral genome into the host cell genome.

Desensitization to prevent an allergic response can be accomplished by injecting repeated doses of: Group of answer choices IgE antibodies the antigen (allergen) histamine IgG antibodies antihistamine
Desensitization to prevent an allergic response can be achieved with doses of the antigen.
How do these doses of Antigen cause desensitization?The small and controlled doses of antigen (allergen) can cause desensitization to said allergy. This is because they allow the body to slowly build up natural defenses to this antigen, allowing it to be better prepared to combat said antigen during the next exposure.
Therefore, we can confirm that desensitization to prevent an allergic response can be achieved with doses of the antigen.

What are ocean waves?Ocean waves are the result of the interaction between the ocean and the wind. They are the most visible and powerful manifestations of the Earth's oceans. Ocean waves vary in size, shape, and speed, depending on the wind's strength, duration, and direction. They can range from small ripples to massive swells and can travel thousands of miles before breaking on shorelines.
The energy of ocean waves is harnessed for various purposes, such as surfing, fishing, and generating electricity through wave energy converters. However, ocean waves can also be destructive, causing erosion and flooding in coastal areas during storms.
Ocean waves play a crucial role in regulating the Earth's climate by transferring heat and energy from the tropics to the poles. They also help distribute nutrients and oxygen to marine life, and their movement influences the ocean's circulation patterns.

How would the inherited traits discussed in this lesson be influenced if those alleles were on a s3x chromosome? Would the probability of inheritance change?
(an example"traits discussed" is wired haired dogs and smooth coated dogs)
I'd really appreciate the help! :D
The discussed inherited traits would not be influenced if these alleles were on an s3x chromosome, the probability of inheritance would not change.
To understand the answer, we need to know about s3x chromosomes
What are s3x chromosomes?Females have two identical chromosomes (XX), while males have an X chromosome and a smaller chromosome called a Y. Human males are heterogametic with two different s3x chromosomes (XY). Human females are the gametic s3x (XX).
With this information, we can conclude that the discussed inherited traits would not be influenced if these alleles were on an s3x chromosome, the probability of inheritance would not change.

In treating victims of carbon monoxide poisoning, artificial respiration is first applied in the open air, followed by the administration of a mixture of 93% oxygen and 7% carbon dioxide. The carbon dioxide
a. stimulates the breathing centre
b. increases the diffusion of oxygen
c. displaces the carbon monoxide on the hemoglobin
d. increases the diffusion of carbon dioxide out of the lungs
Displaces the carbon monoxide on the hemoglobin. Therefore, option (C) is correct.
What is carbon monoxide poisoning?Carbon monoxide (CO) poisoning occurs when an individual inhales excessive amounts of this colorless, odorless, and tasteless gas. Carbon monoxide is produced by the incomplete combustion of fossil fuels, such as gasoline, natural gas, coal, or wood. When inhaled, carbon monoxide binds to hemoglobin in the bloodstream, preventing it from carrying oxygen to the body's tissues, leading to symptoms such as headache, dizziness, nausea, confusion, and in severe cases, coma or death. Carbon monoxide poisoning can occur in poorly ventilated areas, or from faulty appliances, such as furnaces, water heaters, or cars left running in a closed garage. Early detection and treatment are essential for a successful outcome.
Carbon dioxide competes with carbon monoxide for binding sites on hemoglobin, and has a higher affinity for those sites. As a result, administering a mixture of 93% oxygen and 7% carbon dioxide can help to displace the carbon monoxide from the hemoglobin, allowing the oxygen to bind and be transported to the tissues that need it.
Therefore, option c. displaces the carbon monoxide on the hemoglobin is the correct option.
