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.

secretory proteins that enter the exocytosis pathway do not require a signal to be secreted outside the cell.
The secretory pathway incorporates proteins to the telephone surface membrane the place they can be released. This method can be divided into two systems: the regulated secretory pathway, and the constitutive secretory pathway. For many proteins in the constitutive secretory pathway, this transport technique takes place at a quite regular price that is determined by using how quickly these proteins are synthesized. However, the regulated secretory pathway operates by developing a storage compartment inside cells to save the secretory cargo. Upon the fabulous stimulus, these storage booths can fuse with the mobile floor and permit a burst of contents to be unexpectedly secreted. Regulated secretion is used in the course of multicellular organisms to accomplish a broad range of tasks such as hormonal control and neuronal communication.

d)Provides genetic variation, but time-consuming
Answer:
answer would be the options C and D.
The true statements about sexual reproduction are: (c) Sperm fertilizes egg; (d) Provides genetic variation, but time-consuming.
In sexual reproduction, two specialized reproductive cells known as gametes from different individuals, typically male and female, unite to form a zygote. In many organisms, sperm from the male fertilizes the egg from the female, resulting in the development of a new organism.
Sexual reproduction leads to genetic variation because it involves the recombination of genetic material from two parents, creating offspring with a unique combination of traits. This genetic diversity is beneficial for the survival and adaptation of species to changing environments.

why does heart rate increase during exercise? a) to move sweat to the skin b) to increase the signals to the muscles that cause muscle contraction c) because the blood pressure increases, which causes the heart rate to increase d) because the "adrenaline rush" signals for the heart to beat faster e) to increase oxygen (o2) delivery to muscles
"The heart rate increases during the exercise because the "adrenaline rush" signals for the heart to beat faster and to increase the oxygen delivery to muscles."
The heart normally beats more quickly during physical activity so that more blood can reach the body. By pumping more vigorously or by increasing the volume of blood that fills the left ventricle before it pumps, the heart increases the stroke volume. The amount of oxygen the muscles need to make energy increases during exercise. The heart needs to pump more oxygen-rich blood through the arteries during the exercise to meet the energy requirement.

The categorization system offers a wealth of knowledge regarding the traits of creatures. Therefore, using a scientific term as a shorthand to describe a plant or animal might be useful.
Aristotle was the first scientist to categorize organisms. He identified straightforward morphological traits and used them to divide organisms into the categories of plants, shrubs, trees, and herbs. Animals with red blood cells (Enaima) and those without red blood cells (other species) were divided into two categories by him (Anaima).

If an individual has 10 gene pairs, how many different gametes can be formed if three of the gene pairs are homozygous and the remaining seven gene pairs are heterozygous?.
128 different gametes can be formed if three of the gene pairs are homozygous and the remaining seven gene pairs are heterozygous.
According to Mendel's Law of Independent Assortment, the process through which one gene pair on one homologous chromosome pair separates and assorts during meiosis does not impact how another gene pair on a different homologous chromosome pair separates and assorts. Consequently, among the gametes that a doubly heterozygous individual with the Aa Bb genotype can generate, each of these two allele combinations is equally likely: AB, Ab, aB, and ab. Through self-assortment, sexually reproducing organisms can introduce genetic variety into a population.
The number of different alternative gamete genotypes that a person may generate for independently assorting gene pairs is equivalent to 2n, where n represents the number of gene pairs at which the person is heterozygous. Consequently, if a person has 10 gene pairs but is only heterozygous for 7 of them, the number of alternative gamete genotypes is 27 or 128
