What is the role of spindle fibers in mitosis?

Answers

Answer 1

Answer:

They help equally devide the cell.

Explanation:

Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.

Answer:

The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis.

Explanation:

During mitosis, the spindle fibers are called the mitotic spindle. Their proteins help to hold the sister chromatids together and also play a role in chromosome editing.is a protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart.

Which scientific area has the most influence in shaping modern classification methods?

Answers

Answer: The answer is " evolution". Evolution is a major force in shaping modern classification methods. Evolution is the adjustment in the qualities of an animal categories more than a few ages and depends on the procedure of common determination.

The scientific field which has had the greatest influence on shaping modern classification methods is Evolution.

What is Evolution?

Evolution is concerned with the sequence of changes which occur in organisms as they transform from their ancient forms to their modern forms.

It is the change in the genetic characteristics of a biological population over successive generations. These characteristics are manifestations of genes passed from parents to offspring during reproduction.

The three main types of Evolution are:

1. Divergent Evolution

2. Convergent Evolution

3. Parallel Evolution

Thus, the scientific field which has had the greatest influence on shaping modern classification methods is Evolution.

Which best describes how to classify water?

Answers

a ) it’s made of its own substance

While dry cleaners are small businesses, they generate relatively large volumes of hazardous substances. EPA estimates the average dry cleaner generates 660 gallons of hazardous wastes a year. Unlike petroleum contamination which may break down over time by naturally-occurring bacteria in the environment, the chlorinated solvents that are used by dry cleaners are resistant to biodegradation. As a result, groundwater contamination from dry cleaners has a greater potential to migrate off-site which can be problematic since dry cleaners are often located within proximity to residential neighborhoods. Indeed, a 2002 Florida study found that dry cleaner contamination had migrated off-site at 57 percent of the contaminated sites. Due to these types of environmental hazards when commercial land is sold require a Phase 1 Environmental Assessment according to the Comprehensive Environmental Response, Compensation and Liability Act. Why would the type of monitoring required as part Phase 1 Environmental Assessments be important if a dry cleaner was being sold?


A) The monitoring will indicate any environmental damage done that should be remediated prior to selling the land.


B) This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.


C) The monitoring prevents the land from being resold to any dry cleaning businesses which can be damaging to the environment.


D) The monitoring will allow the government to determine which type of business is better for the environment so dangerous businesses can be closed.

Not all organism that are born can be supported by the environment because organisms (blank) for resources

Answers

Answer:

This blank space in this question is COMPETE

Explanation:

This question is describing natural selection, which is the theory proposed by Charles Darwin where he stated that organisms that are better suited for an environment will survive and reproduce better than others.

In the environment, resources such as food, water, mate etc are limited, hence, organisms must COMPETE for the available ones. In this case, organisms that are better adapted will triumph over others. Therefore, it is certain that not all organism that are born can be supported by the environment because organisms COMPETE for resources.
