muscularis Intra mural plexus is the name given to the plexus found between layers of muscle.
The myenteric plexus, a component of the enteric neural system, is located in the gastrointestinal tract between the longitudinal and circular layers of muscularis externa. It is present in the esophageal, stomach, and intestinal muscles.
Although the present ganglion cell bodies belong to parasympathetic innervation, fibers from sympathetic innervation also reach the plexus. The submucous plexus provides secretomotor innervation to the mucosa closest to the gut lumen. The myenteric plexus (or Auerbach's plexus) provides motor innervation to both layers of the muscular layer of the gut. It develops from cells in the medulla oblongata's vagal trigone, also referred to as the nucleus ala cinerea, the parasympathetic nucleus of origin for the tenth cranial nerve (vagus nerve).

Explanation:
In the United States about 16% of the population is Rh negative. The allele for Rh negative is recessive to the allele for Rh positive. If the student population of a high school in the U.S. is 3,000, how many students would you expect for each of the three possible genotypes?
In certain African countries, 4% of newborn babies have sickle-cell anemia, which is a recessive trait. Out of a random population of 10,000 newborn babies, how many would you expect for each of the three possible genotypes?
Answers
In the high school population of 3,000 students, 2,117 students were homozygous Rh positive (AA), 806 students were heterozygous (Aa), and 77 students were homozygous Rh negative (aa).
Given:
Population size: 3,000 students
Rh negative population frequency: 16% (0.16)
From the Hardy-Weinberg equation.
p: frequency of the dominant Rh positive allele
q: frequency of the recessive Rh negative allele
We know that p + q = 1
p = 1 - q = 1 - 0.16 = 0.84.
The expected frequencies of the three genotypes are:
Homozygous Rh positive (AA): p² = (0.84)² = 0.7056
Heterozygous (Aa): 2pq = 2 ₓ 0.84 ₓ 0.16 = 0.2688
Homozygous Rh negative (aa): q² = (0.16)² = 0.0256
Homozygous Rh-positive: 0.7056 ₓ 3,000 = 2,116.8 (approximately 2,117 students)
Heterozygous: 0.2688 ₓ 3,000 = 806.4
Homozygous Rh negative: 0.0256 ₓ 3,000 = 76.8
Sickle-Cell Anemia in a Newborn Population:
Given:
Population size: 10,000 newborn babies
Sickle-cell anemia frequency: 4% (0.04)
p: frequency of the dominant normal allele
q: frequency of the recessive sickle-cell allele
p + q = 1
p = 1 - q = 1 - 0.04 = 0.96.
The expected frequencies of the three genotypes are:
Homozygous normal (AA): p²= (0.96)² = 0.9216
Heterozygous (Aa): 2pq = 2 ₓ 0.96 ₓ 0.04 = 0.0768
Homozygous sickle-cell (aa): q² = (0.04)² = 0.0016
Homozygous normal: 0.9216 ₓ 10,000 = 9,216
Heterozygous: 0.0768 ₓ 10,000 = 768
Homozygous sickle-cell: 0.0016 × 10,000 = 16

Carbon is a component of all organic substances, including proteins, carbohydrates, and lipids, and all plant and animal cells are made up of these components and their polymers. Numerous straightforward molecules are joined together in precise ways to form polymers, which are macromolecules. Most industries in the world use carbon in some capacity. Coal, methane gas, and crude oil are all utilised as fuels (which is used to make gasoline). It is used to create a variety of products, including plastic and steel alloys (a combination of carbon and iron). The majority of the carbon on Earth is preserved in rocks and sediments, with the remainder found in the ocean, atmosphere, and living things.

in pea plants, the allele for tall plants is dominant and the allele for short plants is recessive. Two heterozygous plants are crossed. What is the probability that an offspring will be short? OA. 0.75 OB. 0.25 OC. 1.00 OD. 0.50
Answers
The probability that an offspring will be short when two heterozygous pea plants are crossed is: B. 0.25
How to Determine the Probability of Offspring produced in a cross?When two heterozygous pea plants (Tt) are crossed, the probability of an offspring being short (tt) can be calculated using Punnett square analysis.
In this case, 25% of the offspring will inherit the recessive allele from both parents, resulting in a short plant phenotype.
The Punnett square is given below:
| T | t |
T | TT | Tt |
t | Tt | tt |
In the Punnett square, the combinations in the bottom row (Tt and tt) represent the possible genotypes of the offspring. As we can see, there is a 25% chance (1 out of 4) for an offspring to have the tt genotype, which corresponds to a short plant phenotype.
Therefore, the probability of an offspring being short is 0.25 or 25% (option B).

According to the given that actual flower position is dominant over terminal flower.
What is a homozygous dominant plant?When an organism possesses two copies of the same dominant allele, it is said to be homozygous dominant, and when it possesses two copies of the same recessive gene, it is said to be homozygous recessive.
When an organism is homozygous, it contains two copies of the same allele for a gene. When two copies of the same dominant allele or two copies of the same recessive allele are present in an organism, it is said to be homozygous dominant or homozygous recessive.
When an organism is heterozygous, it has two distinct alleles of the same gene. For instance, pea plants can have either homozygous dominant (red-red) or heterozygous red blooms (red-white). They are homozygous recessive if they have white blooms (white-white). Heterozygous carriers are always present.

If illegal hunting of oxpeckers increases in 2012 and causes a decrease in oxpecker numbers, what will most likely happen to
rhinoceros populations?
Answers
a decline in oxpecker numbers is probably going to be bad for rhinoceros populations.
Oxpecker numbers are projected to decline as a result of increased unlawful hunting, which will have a negative impact on rhinoceros populations.
The ticks and parasites that live on the skin of rhinoceroses and other large mammals provide the food source for oxpeckers, which are birds. By keeping the animals free of parasites and warning them of imminent danger, they offer an important service.
The number of ticks and other parasites on rhinoceroses may increase if oxpecker populations drop as a result of hunting, which could result in health issues and lower survival rates. In addition, rhinoceroses might be more susceptible to predators and other dangers without oxpeckers to provide warning sounds. So, a decline in oxpecker numbers is probably going to be bad for rhinoceros populations.

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water
Answers
The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.
Why do polar molecules repelled by the phospholipid bilayer?Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.
What component of the phospholipid bilayer is water-repellent?While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

include a link to each source. Be sure to also include the name of the website or organization that
published the source.
Answers
Answer:
carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. At least one-quarter of the carbon dioxide (CO2) released by burning coal, oil and gas doesn't stay in the air, but instead dissolves into the ocean. Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2 from the atmosphere, presently around 22 million tons per day.
At first, scientists thought that this might be a good thing because it leaves less carbon dioxide in the air to warm the planet. But in the past decade, they’ve realized that this slowed warming has come at the cost of changing the ocean’s chemistry. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact. In the past 200 years alone, ocean water has become 30 percent more acidic—faster than any known change in ocean chemistry in the last 50 million years.
Scientists formerly didn’t worry about this process because they always assumed that rivers carried enough dissolved chemicals from rocks to the ocean to keep the ocean’s pH stable. (Scientists call this stabilizing effect “buffering.”) But so much carbon dioxide is dissolving into the ocean so quickly that this natural buffering hasn’t been able to keep up, resulting in relatively rapidly dropping pH in surface waters. As those surface layers gradually mix into deep water, the entire ocean is affected.
Such a relatively quick change in ocean chemistry doesn’t give marine life, which evolved over millions of years in an ocean with a generally stable pH, much time to adapt. In fact, the shells of some animals are already dissolving in the more acidic seawater, and that’s just one way that acidification may affect ocean life. Overall, it's expected to have dramatic and mostly negative impacts on ocean ecosystems—although some species (especially those that live in estuaries) are finding ways to adapt to the changing conditions.
However, while the chemistry is predictable, the details of the biological impacts are not. Although scientists have been tracking ocean pH for more than 30 years, biological studies really only started in 2003, when the rapid shift caught their attention and the term "ocean acidification" was first coined. What we do know is that things are going to look different, and we can't predict in any detail how they will look. Some organisms will survive or even thrive under the more acidic conditions while others will struggle to adapt, and may even go extinct. Beyond lost biodiversity, acidification will affect fisheries and aquaculture, threatening food security for millions of people, as well as tourism and other sea-related economies.

2.to absorb oxygen from the water into the bloodstream
3.to take in oxygen and transport it to the lungs
4.to regulate body temperature
Which one is it!
Answers
Answer:
Fish have gills in order to extract oxygen from the water and absorb it into their bloodstream. This allows them to breathe underwater, as opposed to mammals like humans who require air to breathe. states that "gills require a huge amount of water to provide the necessary gas exchange. The gills also pass carbon dioxide into the water in the same way as lungs breathe it out into the air. As the water passes over the gills, the blood in the fish absorbs oxygen from the water."
Option 2, "to absorb oxygen from the water into the bloodstream," is the correct answer. Gills do not absorb nutrients from the water into the digestive system (option 1), transport oxygen to the lungs (option 3), or regulate body temperature (option 4). also mention that gills are used by fish to expel nitrogenous waste and regulate the pH or acidity in their bodies, but the primary function of gills is to extract oxygen from the water and absorb it into the bloodstream.
