Explanation:
cd103 and cd103 bronchial lymph node dendritic cells are specialized in presenting and cross-presenting innocuous antigen to cd4 and cd8 t cells.
Answers
The correct answer is because these cells are largely absent in CCR7(-/-) mice derived from the lung and that CCR7 expression is required for their migration from the lung to the draining lymph node.
Cross-presentation occurs when dendritic cells (DC) capture, process, and present exogenous Ag to CD8(+) T lymphocytes via MHC class I. We show that CD103(+) (CD11c(high)CD11b(low)) and CD103(-) (CD11c(int)CD11b(high)) DC in the lung-draining bronchial lymph node (brLN) have evolved to have opposing functions in presenting innocuous inhaled Ag. Thus, under tolerogenic conditions, CD103(-) DC present innocuous Ag to CD4(+) T cells, whereas CD103(+) DC, which do not express CD8alpha, present Ag exclusively to CD8(+) T cells. Ag-carrying CD103(+) DC are largely absent in the brLN of CCR7-deficient mice but not in plt/plt mice, despite the presence of CD103(+) DC in the lung of CCR7-deficient mice.

A caldera is a crater which has:
Answers
Answer: become very large because of the collapse of its walls
Explanation:
A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is lost. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018.

the interactions between two proteins such as an antibody and an antigen or a hormone and its receptor are quite strong despite the fact that these interactions consist of relatively weak noncovalent bonds. how can this be?
Answers
This observation is explained by the concept of molecular complementarity.
Concept of molecular complementarity.
Because there are so many noncovalent interactions happening when proteins, such as an antibody and an antigen, match up in a way that creates many noncovalent bonds, even weak noncovalent bindings can effectively produce strong interactions between two proteins.
When the structures of molecules or macromolecules fit together, physical, non-covalent interactions cause them to associate reversibly with one another. This is known as molecular complementarity.

An extrachromosomal DNA molecule known as a "tumor-inducing plasmid," or "Ti-plasmid," is frequently identified in the plant pathogen Agrobacterium tumefaciens.
In addition to other well-known opianes like nopaline, fig and chrysanthemum plant galls that strains of Agrobacterium naturally generated contained three tumor-specific opinelike compounds. Deoxy-fructosyl-glutamine (dfg), deoxy-fructosyl-5-oxo-proline (dfop), and chrysopine were the compounds that were identified. Based on hybridization with several vir and T-DNA probes, it was determined that the strains recovered from Fig tree and chrysanthemum tumors carried unique and unrelated Ti plasmids. They also showed various opine-catabolic characteristics. Chrysopine was metabolized by the strains isolated from fig trees and chrysanthemum plants (Chry strains), but only the Chry strains utilised dfg and dfop. Surprisingly, other Agrobacterium strains catabolized these two molecules: dfg was broken down by the majority of pathogenic and nonpathogenic Agrobacterium strains, and dfop by every Agrobacterium strain that breaks down agropinic acid. These findings support earlier hypotheses regarding the development of opine-related functions and have strong ecological and evolutionary implications.Learn more about the Ti plasmid with the help of the given link:

Which layer is where most of the x-rays & gamma rays from the sun are absorbed and the ionosphere is found?.
Answers
The layer where most of the x-rays & gamma rays from the sun are absorbed and the ionosphere is found is Thermosphere.
The layer of incredibly rare air above the mesosphere is referred to as the thermosphere. The high-energy X-rays and UV radiation from the Sun heat the thermosphere to hundreds or perhaps thousands of degrees. We would, however, feel quite cold in this stratum due to how thin the air is.
In many ways, the thermosphere is more like outer space than the atmosphere. Actually, lots of satellites orbit the planet inside the thermosphere! Variations in the energy coming from the Sun have a significant impact on the temperature and height of the top of this layer.
The ionosphere is not a discrete layer. The ionosphere, on the other hand, is a collection of places in some mesosphere and thermosphere where high-energy radiation from the Sun has jarred electrons free of their parent atoms and molecules. The ionosphere gets its name from the electrically charged atoms and molecules that are created in this process; these ions also give this region some unique features.

7. one molecule of dietary glucose can be oxidized through glycolysis and the citric acid cycle to generate a maximum of 32 molecules of atp. calculate the fraction of this energy that is lost when the glucose is stored as glycogen before it is catabolized.
Answers
6.25% of the energy contained in glucose is lost during the storage process. Glycolysis produces the molecules that are processed by the citric acid cycle.
Each dietary glucose molecule produces 32 molecules of ATP when it enters the glycolysis and oxidation pathways directly. A net 2 ATP are produced during glycolysis for every gram of glucose. Per glucose, the citric acid cycle generates an extra 2 ATP. 28 ATP are produced by oxidative phosphorylation using the byproducts of glucose catabolism. 32 ATP molecules are created in this way. A cell could potentially store dietary glucose for later use, in the form of glycogen. One ATP must be used in this process in order to create glucose-1-phosphate (G1P). After then, G1P and UTP (uridine triphosphate) combine to form uridine-diphospho-glucose (UDP-glucose or UDPG). The UTP substrate, which is used in this phase, indirectly consumes ATP. Glycogen synthase can then utilise UDPG directly in the production of glycogen. This implies that each additional molecule added to a glycogen polymer uses up two ATP molecules.If two ATP molecules are used up during the storage of glucose as glycogen, then 2/32 or 6.25% of the energy contained in glucose is lost during the storage process.Learn more about the Glycolysis with the help of the given link:

What is the ultimate destination of the electrons that are extracted from glucose during cellular respiration?.
Answers
The ultimate destination of the electrons that are extracted from glucose during cellular respiration is that they are used to form water.
The stage of cellular respiration known as the electron transport chain, or ETC, is made up of protein complexes. It transfers the electron generated by the Kreb's cycle and glycolysis through a redox process (citric acid cycle).
By combining hydrogen and oxygen to generate a water molecule, the ETC first creates a gradient before reducing the molecular oxygen. Cellular respiration results in the release of water and carbon dioxide. The final electron carrier is the water that is thus created.
As a result, the electron in the ETC phase of cellular respiration ends up in a water molecule.

What is Allele?
At a specific genomic region, an allele is one of two or more variations of the DNA sequence (a single base or a segment of nucleotides). For each genomic region with such variation, an individual inherits two alleles, one from each parent. The person is homozygous for the allele if the two alleles are the same.
A dominant allele, which can come from just one parent, causes a dominant phenotype in those who possess one copy of the gene. A person needs two copies of a recessive allele, one from each parent, for it to result in a recessive phenotype. One dominant and one recessive allele for a gene will result in a person with the dominant phenotype.
Hence, The black snake will provide B or b. The white snake will always provide b. So the genotypes would be Bb half the time and bb the other half. Therefore, 50% of their offspring will have the genotype Bb. Since they had 8 eggs, it is likely that half, or 4, will be white.

kinesin i and cytoplasmic dynein orchestrate glucose-stimulated insulin-containing vesicle movements in clonal min6 β-cells.
Answers
In clonal MIN6 -cells, kinesin I and cytoplasmic dynein coordinate the migration of insulin-containing vesicles in response to glucose.
For prolonged insulin production, large dense-core vesicles (LDCVs) must be mobilized by glucose and transported to the plasma membrane. The cytoskeletal components and molecular drivers involved in vesicle trafficking in -cells are still not well understood. Here, we discuss the simultaneous imaging of LDCVs and microtubules in -cells that have been tagged with an enhanced green fluorescent protein (EGFP). Vesicles travel along the tangled network of microtubules, which characterize intricate directional movements. Even though LDCVs frequently changed direction, suggesting the involvement of both plus- and minus-end directed motors, inactivating the minus-end motor, cytoplasmic dynein, only partially inhibited all vesicle movements that were involved in vesicle recovery after glucose-stimulated exocytosis. The plus-end motor, kinesin I, was selectively silenced by short interfering RNAs, which significantly reduced all vesicle motions. We determine that Kinesin I is primarily responsible for LDCV transport in -cells, while dynein is likely involved in the recovery of vesicles following rapid kiss-and-run exocytosis.
