Answer: 1. The corona is in the outer layer of the Sun's atmosphere—far from its surface. Yet the corona is hundreds of times hotter than the Sun's surface. ... In the corona, the heat bombs explode and release their energy as heat. But astronomers think that this is only one of many ways in which the corona is heated. Our Sun is surrounded by a jacket of gases called an atmosphere. The corona is the outermost part of the Sun's atmosphere. The corona is usually hidden by the bright light of the Sun's surface. ... During a total solar eclipse, the moon passes between Earth and the Sun. 2. The chromosphere is above the photosphere, the visible "surface" of the Sun. It lies below the solar corona, the Sun's upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density. Chromosphere is a reddish and glowing layer of gas above a star's (or Sun's) photosphere. It is actually the transition between corona and the photosphere. Out of the three layers of the Sun's atmosphere, chromosphere is the second one (with photosphere being the first layer and corona as the third) 3. The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. 4. The convection zone is the outer-most layer of the solar interior. It extends from a depth of about 200,000 km right up to the visible surface. At the base of the convection zone the temperature is about 2,000,000° C. Convection zone: This layer of the sun is above the radiative zone and is the outermost layer of the Sun's interior. It stretches from as deep as around 200,000 kilometers right up to the visible surface. ... Energy moves towards the Sun's surface through convection currents of heated and cooled gas. 5. The Sun's radiative zone is the section of the solar interior between the innermost core and the outer convective zone. In the radiative zone, energy generated by nuclear fusion in the core moves outward as electromagnetic radiation. In other words, the energy is conveyed by photons. This is the zone immediately next to the core, which extends out to about 0.7 solar radii. There is no thermal convection in this layer, but solar material in this layer is hot and dense enough that thermal radiation is all that is needed to transfer the intense heat generated in the core outward. 6. The Sun's central core is plasma with a temperature of around 27 million C . At such high temperatures hydrogen combines to form helium by nuclear fusion, a process that releases vast amounts of energy. This energy moves outward, towards the outer layers of the Sun. The core is the Sun's middle region where energy is generated by thermonuclear reactions, which create extreme temperatures of about 15 million degrees Celsius. These nuclear reactions use hydrogen to produce helium. brainliest?
Explanation:
Which of the following most directly explains the changes in the cells?
A
The degradation of DNA in the nuclei of the cells
B
The lysis of chloroplasts in the cells
C
The movement of water from the central vacuoles of the cells into
the solution
D
The movement of NaCl from the solution into the cytoplasm of
the cells
C. The movement of water from the central vacuoles of cells into the solution
The most direct explanation for changes in cells is the flow of water from the core vacuoles of the cells into the solution. Water enters and exits cells via osmosis. Thus, option C is correct.
What are the major changes in cells?Aging causes alterations in all cells. They enlarge and lose their capacity for division and multiplication. In addition to other modifications, the cell's inside now contains more colors and fatty compounds (lipids).
To increase tissue, cells regularly proliferate by themselves. This may occur while an organism is developing or when it sustains an injury and needs to heal itself.
Therefore, the movement of water from the central vacuoles of the cells into the solution most directly explain changes in cells.

Why will individuals have brown eyes rather than a blue eyes?
Answer:
because of the parent's genes
Explanation:
You identify an auxotroph that doesn't grow in normal medium, but does grow in medium supplemented with Q, indicating that it has a defect in one or more enzymes in this pathway. This auxotroph is also able to grow if you supplement the medium with Y. Based on this, which enzymes can you say with certainty is/are disrupted by the mutation
Answer: Enzymes in both Q and Y pathway are disrupted because you have to supplement the medium with those components for the organism to grow.
Explanation:
A microorganism is auxotrophic when it is only able to proliferate in a culture medium if some specific substance has been added to it, which the wild type (prototroph) does not require, because it can synthezise it. The underlying genetics of auxotrophy is the lack of a functional metabolic pathway that generates the substance on which the auxotroph depends. This lack is usually due to a mutation that generates a null allele lacking biological capacity. So, due to a deficiency in an enzyme required for the synthesis of a certain component, the organism requires that component in the culture medium in order to grow.
A metabolic pathway is a set of consecutive chemical reactions catalyzed by enzymes synthesized by the cell, in which the product of one is the substrate of another. In living organisms there are multiple metabolic pathways, responsible for synthesizing and metabolizing compounds (cellular components, regulatory molecules, compounds that serve to store energy), or degrading them to obtain energy. Thus, enzymes catalyze chemical reactions, this means they accelerate the rate of reaction.
A normal medium is one that possesses all the nutrients and compounds necessary for the proper functioning of a normal organism (prototroph). However, if the organism lacks, for example, an enzyme, it will not grow in a normal medium because it does not have the enzyme to make the components. If the organism does not grow in the normal environment, then it has some mutation that causes some enzyme not to be produced. Remember that enzymes are proteins, and all proteins are encoded by DNA, so if there is a mutation in the DNA, in the gene that encodes the enzyme, the enzyme will not be synthesized or will be synthesized but in such a way that it cannot function properly.
If the organisms only grow in medium supplemented with Q and in medium supplemented with Y, then this indicates that it has a defect in one or more enzymes in Q and Y pathway, because the organism cannot produce certain components and they need to be added in the environment. The problem does not provide enough information to know if for each pathway only one enzyme is affected or several, but it is enough to say that enzymes in both Q and Y pathway are disrupted because you have to supplement the medium with those components for the organism to grow.
Which statement about the factors that affect the affinity of hemoglobin for oxygen are FALSE? Group of answer choices Decreased O2 partial pressure diminishes affinity and this favors oxygen unloading and delivery to the tissues. CO2 increases the affinity of oxygen for hemoglobin so that hemoglobin binds oxygen more strongly. Decreased blood temperature increases hemoglobin affinity for oxygen. The affinity of hemoglobin for oxygen is higher than for carbon dioxide which results in oxygen being able to displace carbon dioxide from hemoglobin as the blood travels through the pulmonary capillaries. With decreasing pH, affinity decreases so that more oxygen is released from hemoglobin.
Answer:
CO2 increases the affinity of oxygen for hemoglobin so that hemoglobin binds oxygen more strongly
Explanation:
Hemoglobin (Hb) is a protein found in red blood cells that functions to transport oxygen (O2) to the tissues. This protein has four subunits and each subunit binds to a heme group. Each heme group in Hb contains an iron atom that binds to one O2 molecule. The affinity of hemoglobin for O2 is a critical mechanism that is dependent on the ability of Hb to carry O2 molecules. Hb is fully saturated with O2 when all of its four O2-binding sites are occupied. Moreoever, the O2-hemoglobin dissociation curve is a plot of saturation of Hb regarding the partial pressure of O2 (PO2). A rightward shift in the curve indicates that Hb has a decreased affinity for O2, while a leftward shift in the curve indicates that Hb has an increased affinity for O2. As CO2 concentration increases, hemoglobin's affinity for O2 decreases, thereby Hb binds to O2 less tightly at heme group sites and therefore the dissociation curve shifts to the right.

The component of a vaccine that makes it effective is the antigen.
What is a Vaccine?
A vaccine is basically a biological preparation that provides active acquired immunity to a particular disease. It contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. Vaccines are designed to stimulate the body's own immune system to protect the person against subsequent infection or disease.
11) An antigen is a substance that causes the body to produce antibodies when it enters the body. These antibodies help the body recognize and fight the antigen if it enters the body again.
12) A vaccination is a way of introducing a weakened or killed version of a particular virus, bacteria, or toxin into the body. This weak or dead version of the virus, bacteria, or toxin stimulates the body's natural defense system to produce antibodies that are specific to that virus, bacteria, or toxin. These antibodies can then recognize and fight off the real virus, bacteria, or toxin if the body is ever exposed to it, thus preventing the individual from getting the disease. This is known as active immunity. The immunity created by the vaccination is typically long-lasting, and in many cases, lifelong.

Explain briefly how these features contribute to the efficiency of photosynthesis?
Answer:
here's your answer
Explanation:
the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.
Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves

how does PAMPs activate infectious Inflammation
Answer:
Activation of infectious inflammation:
PAMPs are derived from microorganisms and thus drive inflammation in response to infections. After identifying microorganisms infections PAMPs by PRRs, activate cytoplasmic complexes called inflammasomes.
After activation of inflammasomes, these inflammasomes activate the protease caspase-1, which then cleaves or breaks various pro-inflammatory cytokines, resulting in maturation and cellular release that cause inflammatory reactions.
