Explanation:
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.

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?

Answer:pls what is the question cause im not sure what it is asking
Explanation:
As with all multicellular organisms, homeotic genes in plants control morphogenesis (how the tissues and organs of the plant are arranged). in maize plants, the homeotic gene knotted1 (abbreviated kn1) maintain the indeterminate state of shoot apical meristems. in wild-type maize plants, kn1 is expressed at high levels in the shoot apical meristem, but is expressed at low levels in leaves. in some mutant maize plants, kn1 is expressed at high levels in leaves. in those plants, outgrowths or knots of adventitious shoot meristems (shoot meristems that appear in abnormal locations on the leaves) form. use this information to determine which of the following statements are true. select the four statements that are true.
a. expression of the kn1 gene in shoot apical meristem cells produces a protein involved in the maintenance of shoot apical meristems.
b. in wild-type maize plants, the kn1 gene is mostly expressed in shoot apical meristem cells.
c. in mutant maize leaves, the kn1 gene is mostly not expressed.
d. leaves of the mutant maize plants produce more kn1 protein than leaves of wild-type maize plants.
e. both the wild-type and mutant maize leaves have the same morphology.
f. in wild-type maize plants, the kn1 gene is present in shoot apical meristem cells, but not in leaf cells.
g. in wild-type maize plants, the kn1 gene is expressed diferentially in shoot apical meristem cels and leaf cells.
Answer:
a. True
b. True
c. False
d. True
e. False
f. False
g. True
Explanation:
The homeotic genes refer to evolutionarily conserved genes that modulate the development of different structures in organisms of the same groups (in this case, plants). Moreover, homeobox genes are genes that encode transcription factors involved in the regulation of development in eukaryotic organisms. The knotted1 (kn1) gene is a plant homeobox gene is a member of the kn1 homeobox (knox) gene family, which is responsible for maintaining indeterminacy and preventing cellular differentiation. In maize, kn1 plays a key role in maintaining the cells of the shoot apical meristem in an undifferentiated state, being mainly expressed in shoot meristems during postembryonic stages of shoot development. It has been observed that maize mutant plants where kn1 is ectopically expressed (i.e., in tissues in which this gene is not normally expressed) exhibit proximal-distal patterning defects.

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.

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
