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.

how is the hydrosphere connected to the lithosphere
Answer:
Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (lithosphere), or evaporating into the air (atmosphere). Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (lithosphere) to produce electricity.

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

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

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

Do cell membranes contain proteins, but phospholipids and cholesterol
Answer:
In addition to lipids, membranes are loaded with proteins. In fact, proteins account for roughly half the mass of most cellular membranes. Many of these proteins are embedded into the membrane and stick out on both sides; these are called transmembrane proteins.The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable.In addition to the phospholipids, the plasma membranes of animal cells contain glycolipids and cholesterol. ... Because the interior of the phospholipid bilayer is occupied byExplanation:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.How would Darwin explain the change the length of the giraffes neck ?
Answer:
There were mutations that led to some longer necks and some shorter necks, as the trees became taller, the short necks died out due to starvation, leaving behind only the longer necked giraffes. Survival of the fittest.

Which organisms perform photosynthesis in the ocean?
Answer:
Bioplaykton
Explanation:
. Two students are discussing natural selection in bacteria and how it can relate to antibiotic resistance in
bacteria.
Bernadette states that when antibiotics are used, bacteria can respond by developing traits to help them
defeat the antibiotic, which then may increase their fitness.
Dominique states that there is already a variety of traits among the bacteria. Bacteria that have traits that
allow them to survive the antibiotic and reproduce may have higher fitness.
