Gravity play a role in moving tectonic plates at the edge of the plates.
When tectonic plate dives under another plate it is due to the high energy by the Earth's gravity that pushes into the mantle these causes hot rock to rise and cooler to sink .
Movement of tectonic plates occurs on the top of a partially molten layer of rock called the asthenosphere. As a result between contraction of asthenosphere and lithosphere, the plates move contrary to each other at different rates, from 2- 15 centimeters per year. Gravity plays an important role by pulling the denser material close to the core .

In 3 to 5 sentences, describe the relationship between a glucose molecule and the products it makes during cellular respiratio
PLEASE HELP I NEED IT
Answer:
Explanation:
During Cellular Respiration, glucose is broken down into many different pieces turning into pyruvate and releasing electrons. During cellular respiration, this is a process known as glycolysis and takes place in the cytoplasm. The pyruvate then oxidizes (meaning it loses the electrons which produce energy) and turns into acetyl CoA which is used in the Krebs/citric acid cycle.

Mucous membranes are a part of an innate defense that provides the first line of protection against ingested and inhaled infectious agents.
What is innate immunity?
It is a nonspecific type of defense mechanism which is present by birth. It protects us against all antigens and does not depend on prior contact with microorganisms.
It consists of different types of barriers:
Physical barriers: Skin and mucous membrane are the main physical barriers that help in preventing the entry of microorganisms and trapping it.Physiological barriers: HCL in the stomach, saliva in the mouth, tears from the eyes, etc.Cellular barriers: Polymorpho-nuclear leucocytes, monocytes, natural killer cells in the blood, and macrophages in the tissues. They phagocytose and destroy the microbes.Cytokine barriers: Cytokines are secreted by the immune cells that protect the non-infected cells from further infection.Adaptive defense is also called acquired immunity which is pathogen-specific. Humoral immunity produces antigen-specific antibodies and is primarily driven by B cells. Cell-mediated immunity does not depend on antibodies and is primarily driven by mature T cells.
Hence mucous membrane comes under the physical barrier of innate immunity which prevents the entry of microorganisms.

Human gamete is haploid i.e. it contains 23 chromosomes or single set of chromosomes
A cell of an organism is said to be haploid if it only has one pair of chromosomes. All creatures that reproduce sexually are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells are haploid in humans .A haploid cell only contains one pair of chromosomes. Human cells are typically diploid (two copies of each chromosome) as opposed to haploid (one copy of each chromosome). Meiosis, a specific type of cell division where the genetic material of the parent cell is broken up twice, is how the egg and sperm cells are created in humans. As a result, these haploid cells have just one pair of chromosomes. The genetic material is united in the zygote cell that results from sperm fertilizing an egg. In other words, two distinct haploid cells with one set of chromosomes each combine to form a single diploid cell with two sets of chromosomes. In the end, the zygote cell develops into a new individual.

On the ventral surface of the brain, you can observe the optic nerves and chiasma, the pituitary gland, and the mammillary bodies. These externally visible structures form the floor of the Diencephalon
"Diencephalon" is the term used to describe the structures around the 3rd ventricle and form the nucleus of the cerebrum "big brain", the members of the diencephalon are the thalamus, hypothalamus, subthalamus and epithalamus.
Diencephalon Function
The diencephalon plays a role in the motor control of sensory information exchange and the control of autonomic functions of various parts of the body. Examples of some activities that involve the work of the diencephalon are chewing, seeing, eye movements, facial expressions, hearing, breathing, swallowing, smelling and regulating body balance.
Structure and Parts of the Diencephalon
Diencephalon consists of 4 structures that have their respective specific tasks, namely:
1. Thalamus
The thalamus is a structure located in the middle of the brain, precisely between the cerebral cortex and the midbrain. The word thalamus comes from the Greek word which means inner space. The main function of this gland is to convey sensory and motor signals related to consciousness, sleep and alertness to the brain cortex, the thalamus is a suborgan of the diencephalon.
2. Hypothalamus
The hypothalamus is the part of the brain that is the control center of the autonomic system, the hypothalamus is located just above the brainstem. This gland-shaped organ is part of the endocrine system. In humans, the hypothalamus is about the size of a pea and accounts for 1% of the total brain weight.
3. Subthalamus
The subthalamus is an important extrapyramidal motor nucleus that has many connections with other nervous system nuclei. The function of the subthalamus is not yet fully understood, but if there is an abnormality in this part, there will be abnormalities in the movement of the foot or hand that hit strongly on one side of the body.

describe the role that intercostal muscles plays in gas exchange in the lungs
Answer:
Intercostal Muscles Overview
In humans, the muscles are solely for the purpose of expanding and contracting the rib cage. Other animals may have slightly different uses for the intercostal muscles, as discussed in the examples below. While the muscles serve generally the same purpose, they have been adapted in various ways in different organisms. These muscles are considered skeletal muscles.
There are 3 types of intercostal muscle. The innermost intercostal lies inside the ribs. The internal intercostal muscle sits between two ribs. The external intercostal muscles sit on the outside of the ribs. Between each of the 12 ribs, each of these three intercostal muscles is present. The first and last ribs only have intercostal muscles on one side.
The intercostal muscles relax while the lungs are expanding, allowing them to fill up with air. When an organism breathes out, the intercostal muscles contract to put pressure on the lungs and help drive the air out. This cycle continues constantly as an organism breathes.
The innermost intercostal muscles relax, while the external intercostal muscles contract, causing the chest cavity to expand. This expansion allows the lungs to fill with air, due to the negative pressure created by the extra space. Air fills the lungs, gases are exchanged, and it is time to exhale.
Explanation:
Chest Cavity Contraction
To force the air out, the chest cavity must become smaller, to put pressure on the air. To do this, the opposite process of inhalation happens. The diaphragm and external intercostal muscles contract, applying force to the bottom and sides of the lungs. The innermost intercostal muscles now contract, while the external intercostal muscles relax. This causes the chest cavity to contract as a whole, forcing the air out of your lungs. The internal intercostal muscles, or middle layer of muscle, helps keep the ribs from separating and holds the shape of the chest cavity.
Examples of Intercostal Muscles
Intercostal Muscles in Snakes
In different animals, intercostal muscles can perform different tasks. Snakes use their intercostal muscles in a different way than humans, based on their anatomy. Snakes typically only have one functioning lung, which fills along part of their body. Essentially, a snake has reduced its functional skeleton to a spine and rib cage. As in humans, the intercostal muscles in a snake play a role in bringing air into the lungs. By a similar process, the innermost and external intercostal muscles alternate their contracting and relaxing to expand and contract the lung.
Snakes, having no limbs, must also use their intercostal muscles when making a variety of other movements. While they have layers of muscles on top of their ribs that control their motion, the intercostal muscles have a much larger role to play in maintaining the shape and size of the body cavity.
For instance, when a constricting a prey item, a large snake creates an enormous amount of pressure with their muscles. This pressure is exerted not only on the prey item but also on the snake’s own body. To keep itself from damaging its internal organs, the snake must contract its intercostal muscles and create a strong cage around its lung, heart, and other sensitive organs.

Human blood types are determined by genes that follow the codominance pattern of inheritance. there are two dominant alleles (a and b) and one recessive allele (o). if a man that has the blood type aa mates with a woman that has the blood type bo. what are the chances of them having a baby that has "a" blood type?
Answer:
50%
Explanation:
Blood type a and b are codominant, so lets express as 'A and B'
Blood type o is recessive, so is expressed as little 'o'
A man has blood type aa which needs to be written as dominant (in caps) = AA
A woman has blood type bo. The b needs to be dominant and the o stays as little 'o' = Bo
As you can see in the punnet square I have drawn the alleles of the man (AA) at the top and the alleles of the woman (Bo) on the left side to find the alleles of the offspring.
We have the alleles:
AB, AB, Ao, Ao
AB = blood type AB because A and B are codominant which are expressed equally
Ao = blood type A as only A is dominant here which takes express over the recessive 'o'
We have 2 'Ao' out of 4
2/4 = 0.5
0.5 × 100 = 50%
