Explain how does the skeletal system help aid the body when its sick.

1 answer:

4 0

There are several ways by which a skeletal system help aid the body when its sick. Firstly, it helps in producing red blood cells in the body. It also helps in maintaining the level of calcium in the body. It also produces the stem cells that increases the immunity of the body. I hope that the answer has come to your help.

How is cytokinesis different in animals and plants? Animal cells get pinched into two daughter cells by the cell membrane; the p

jasenka [17]

<h2>Let's review what cytokinesis is first.</h2>

Cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.

In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.

In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.

A cleavage furrow is an indentation that appears in the cells surface when the cell is preparing to divide.

So, let's review our options:

A: Animal cells get pinched into two daughter cells by the cell membrane; the plant cell has to form a cell plate before it can create daughter cells.

This would be the correct answer. The only main difference between animal cell cytokensis vs plant cell cytokensis is the cell wall that animal cells lack. Animal cells get pinched into two daughter cells, by the cleavage furrow in the cell membrane, while the plant cell has to form a cell plate before it can create daughter cells.

B: Animal cells give daughter cells a full set of chromosomes at the time of division; plant cells give daughter cells a half set of chromosomes. .

This can be disproven. In meosis, a cell divides into four cells that have half the number of chromosomes. In mitosis, all chromosomes are kept. Both Plant & Animal cells both reproduce using both both meosis and mitosis, so this option is irrelevant.

C: Animal cells require an extra grow phase before cytokensis; plant cells move straight to cytokensis.

Both animal cells and plant cells have the same amount of "grow phases" before cytokensis. This option is irrelevant.

D: Animal cells begin cytokensis during anaphase, plant cells begin around the same time as telophase.

They both begin during the same time. This option is also irrelevant.

Why is reducing caloric intake insufficient for a person to loose weight in a healthy way?

garri49 [273]

Because there are several factors that determine weight loss or gain and reducing calorific intake is just one of them (for reducing weight loss). Other factors that should be considered is exercise. Doing regular exercise ensures that the metabolic rate of the body is increased so much of the calories are burned even after intake. Having a lower metabolic rate can result to increased weight gain even with low calorie intake.

<h3>What is factor analysis?</h3>

Factor analysis is a statistical approach for describing variability in seen, correlated variables in terms of a possibly smaller number of unobserved variables known as factors.
It is possible, for example, that fluctuations in six known variables mostly reflect variations in two unseen (underlying) variables.
Factor analysis looks for such joint fluctuations in response to latent variables that are not noticed.
Factor analysis may be regarded of as a specific form of errors-in-variables models since the observed variables are described as linear combinations of the possible factors plus "error" terms.
It may help to deal with data sets where there are large numbers of observed variables that are thought to reflect a smaller number of underlying/latent variables.
It is one of the most commonly used inter-dependency techniques and is used when the relevant set of variables shows a systematic inter-dependence and the objective is to find out the latent factors that create a commonality.

This would be Mitosis.

Mitosis results in two diploid cells.

Meiosis, on the other hand, results in four haploid cells.

True or false? Populations within ecosystems live in harmony and do not compete with each other.

Rainbow [258]

False in order for an ecosystem to survive there has to be some sort of competition. for example, if there were no sharks to eat little fish the little fish would over populate and then the little fish would run out of food which then means that whatever the little fish ate is now extinct and so on hinting the food chain's name. If it wasn't for competition nothing would survive
