How does binding of complement-opsonized microbes to CR1 facilitate clearing of the microbe from the host? a. Secretion of proinflammatory cytokines b. All of the answers occur as a result of CR1 binding of complement-opsonized microbes. c. Promotion of phagocytosis of opsonized microbes by leukocytes d. None of the answers occur. e. Mediating phagocytosis of C3b-opsonized pathogen by B cells

Answers

Answer 1

Answer:

The correct answer is - b. All of the answers occur as a result of CR1 binding of complement-opsonized microbes.

Explanation:

Binding of complement - opsonized to CR1 makes the microbe palatable to the phagocyte for the phagocytosis and removes the microbe from the host cell. The mechanism of the removal takes place by the promotion of phagocytosis by the leukocytes.

Secretion of the pro-inflammatory cytokines also takes place in the clearing of the microbe and the phagocytosis is mediated by the B cells of the C3b-opsonized pathogen.

Assume a seed eating finch population is currently at carrying capacity and the availability of food decreases dramatically. What will happen to the carrying capacity

Answers

Answer:

This question lacks options, options are:

A.Carrying capacity will increase B.Carrying capacity will decrease C.Carrying capacity will remain unchanged. The correct answer is B.

Explanation:

Ecologists define 'carrying capacity' as the population of a certain species that a defined habitat can support indefinitely, without permanently damaging the ecosystem on which they are dependent,that is, the ecological carrying capacity of an ecosystem is the maximum growth limit of a biological population that the environment can support in a given period, without negative effects on that population or on the environment.

When a strip of bark is removed all the way around the trunk of a tree, the tree dies. Explain why.

Answers

Complete girdling (the bark removed from a band completely encircling the tree) will certainly kill the tree. The reason for damage due to girdling is that the phloem layer of tissue just below the bark is responsible for carrying food produced in the leaves by photosynthesis to the roots.

How do the daughter cells at the end of mitosis and cytokinesis compare with their parent cell when it was in interphase of the cell cycle?

Answers

Answer:

The daughter cells have the same number of chromosomes and the same amount of DNA.

Explanation:

Mitosis is a process where the nucleus divides, so at first we have 46, and we need to bring it down to 23, because that is how much our cells can take, but after mitosis, the daughter cell will end up with 2 new cells, and it will have 23 chromosomes in each of the cells.

Describe what happened to beaver colonies after 1995 (when wolves were reintroduced). Then describe the relationship between the number of beaver colonies and the willow tree ring area.

Answers

Answer:

Decreases.

Explanation:

Decrease occurs in beaver colonies when wolves were reintroduced in the area because wolves feed on beaver and as a result, the population of beaver decreases. There is a direct relationship between the number of beaver colonies and the willow tree ring area because willow tree is a source of food for beavers so if willow tree are more in the area, more food available for the beaver and they will increase in number.

Which statement about this process is true and supported by the equation?


A: The process follows only the law of conservation of mass and not the law of conservation of energy because the number of atoms stays the same, but energy is used up.


B: The process follows only the law of conservation of energy and not the law of conservation of mass because energy is the same in the products, but the number of atoms increases.


C: The process does not follow either the law of conservation of mass or the law of conservation of energy because the number of atoms increases and the amount of energy is reduced.


D: The process follows both the laws of conservation of mass and of energy because the number of atoms stays the same, and the energy is used to make the products, is stored in the products, and is converted to heat.

When does cell differentiation occur?


when cells express different genes


when cells express all genes


when cells express the same gene


when cells do not express genes

Answers

Answer:

The answer is when the cell express different genes.

Explanation:

Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.

The reviewers suggested that you think more carefully about your hypothesis and experimental design. For a chemical to make a good cancer treatment, it is not enough that it harms cancer cells. The chemical needs to have a selective effect on cancer cells--that is, it needs to harm cancer cells much more than it harms normal (noncancerous) cells.

You decide to run a new experiment to test the hypothesis that the fungus chemical harms cancer cells selectively. In this controlled experiment, you will test both cancer cells and normal cells under identical conditions. What data would support this hypothesis?

A human cell in prophase of mitosis can be distinguished from a human cell in prophase I of meiosis by the presence of paired homologous chromosomes in the meiotic cell.

CELL DIVISION:

Cell division involves two processes namely: mitosis and meiosis. Mitosis results in two daughter cells that are genetically identical to one another.

Meiosis, on the other hand, results in four daughter cells that are genetically different from one another.

Mitosis and meiosis as types of cell divisions involves phases namely: prophase, metaphase, anaphase and telophase.

The major difference between prophase of mitosis and prophase I of meiosis is that homologous chromosomes, which are similar but non-identical chromosomes from each parent, are paired.

What impact do trees have on the food web?

Answers

Answer:

Abiotic factors such as latitude and temperature can impact biotic aspects of food web structure like the number of species, the number of links, as well as the proportion of basal or top species. These biotics factors can in turn influence network-structural aspects like connectance, omnivory levels or trophic level. In this way, plants make, or produce, the beginnings of most of the food energy on Earth. This is why plants are called producers. They use some of the food energy to carry out their own functions, and store the rest of the energy in their leaves, stems, roots and other parts.

A: predict percentage of offspring with a trait
B: predict genotypic probabilities
C: track inherited traits through generations
D: identify the genotype of parents

Answers

Answer:

A pedigree chart is used to track inherited traits through generations (option C).

Explanation:

A pedigree chart is a graphical representation, similar to a family tree, showing specific traits present in parents, children and relatives. It is a diagram commonly used in genetics.

A certain phenotype, product of genetic traits, is represented in a pedigree chart by pre-established symbols, which is useful for tracking inherited traits through generations.

The other options, predict percentage of offspring with a trait , predict genotypic probabilities or identify the genotype of parents require a Punnett square to be identified.
