How does the structure of bone allow it to function with the immune system? (PLEASE HELP QUICK THEYRE COMING)

Answer:

In addition to providing a structural support for the body and a reservoir for calcium, bone encases the bone marrow, a primary site for hematopoiesis and immune system development.

Explanation:

The cell cycle is highly regulated and involves many steps to ensure that a cell is ready to divide. For this reason, cells cycle between interphase and mitosis. Suppose a cell culture of 1,000 cells is grown, in which the cells cycle every 24 hours. For a single cell, it takes about two hours from the formation of the dissolution of the nuclear envelope to the separation of two daughter cells.

Which of the following best describes the approximate number of cells in the culture that are in interphase, as well as the consequence of the severe disruption of interphase in mitotic division of cells within a tissue?

A) There are approximately 917 cells in interphase. Disruption of interphase will have no effect on mitosis because they are two completely independent processes.
B) There are approximately 83 cells in interphase. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.
C) There are approximately 917 cells in interphase. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.
D) There are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.

Answers

Answer:

The two major phases of the cell cycle include mitosis (cell division), and interphase, when the cell grows and performs all of its normal functions. Interphase is further subdivided into G1, S, and G2 phases. After the synthesis phase, the cell proceeds through the G2 phase.

Explanation:

what is accuracy, precision, and reproducibility ? and why are they so necessary in conducting/designing experiments

Answers

Answer:

- Accuracy is the degree by which the measures obtained in an experiment and/or observational procedure are associated with true values.

- Precision is the level of reproducibility that these measurements exhibit in the same (constant) conditions.

- Reproducibility indicates the level of agreement of the results when they are obtained by different researchers by applying the same experimental and/or observational procedures.

Explanation:

In a scientific investigation, it is imperative to achieve higher levels of accuracy and precision when realizing measurements because it ensures that the information is correct (without mistakes). Thus, researchers always try to use better equipment and instrument to make their measurements. Reproducibility is important because it is the only condition that scientists can guarantee to other researchers when they arrive at a result.

Multicellular organisms (like us) increase the number of their cells through cell division. One cell divides (parent cell) and becomes two new cells (daughter cells).

explain movement of water in the root

Answers

Answer:

Water initially moves into the root hair cells by osmosis, because the mineral content of the cells is higher than that of the surrounding environment. Thus, a root pressure is established and extends into the microscopic tubes of the xylem.

Explanation:

A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil.she then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill,and the third is placed under a lamp with a green bulb.she records the height of each plant every day for three months.

What is the independent variable in this experiment?

Answers

Answer:

The amount of light they receive.

Explanation:

In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.

The independent variable in this experiment is the amount of light received by each plant.

What is an independent variable?The experimenter manipulates or alters the independent variable, which is expected to have a direct effect on the dependent variable.For example, here the amount of light given to each plant is different and will have an effect on the growth of pea plant.In an experiment, the dependent variable is the variable that is being tested and measured, and it is 'depending' on the independent variable. here the growth of pea plant is dependent variable.

In a typical mammalian cell, what is the average percentage of total cell weight for protein and dna?

Answers

Answer:Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).

Explanation:

A typical mammalian cell averages 18% protein and 0.25% DNA by weight composition.

According to research, a typical mammalian cell is made up of water, ions, and macromolecules such as proteins, lipids, DNA, RNA, carbohydrates, and some miscellaneous metabolites.

The water component of a typical mammalian cell is about 70%, 18% proteins, 1% inorganic ions, 3% small metabolites, 5% lipids, 0.25% DNA, 1.1% RNA, and 2% polysaccharides.

Draw a flow chart that explains how DNA is used to create an organism. please use the words: DNA, gene, protein, cell, tissue, organ, organism.

Answers

Answer:

Please find the flowchart attached as an image

Explanation:

DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.

PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.

Consider the food chain grasshopper mouse snakes hawks. If snakes go extinct what will happen to the food chain

Answers

Answer:

This can actually cause a major problem if the number of grasshoppers were to increase out of control. They eat plants and the number of plants,which are the basis of the food chain, could severely decrease which would impact all of the levels operating above this trophic level.

Answer:

Lack of mice

Explanation:

If the grasshopper where to go extinct the mice population would decrease. Which would lead to it being harder for snakes to find food or they would begin to rely on a different food source. But the hawks would be able to find less snakes but would overall be fine.

fire or other natural disaster but secondary succession does

not.

Primary succession occurs after secondary succession.

Answers

Answer:

Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted.

Explanation:

Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.

- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.

- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.
