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.

Answers

Answer: The answer is A. Infected people

Explanation:

People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Less often, a person might get flu by touching a surface or object that has flu virus on it and then touching their own mouth, nose, or possibly their eyes.

The plate tectonic theory gave the concept of land and sea formation. "Ocean floor evidence of seafloor spreading" acted as evidence to support the plate theory. Thus, option A is correct.

What is plate tectonic theory?

The plate tectonic theory states about the formation of the lithosphere by the movement of the plate tectonics located deep in the mantle and core layer of the earth. These plates show movement slides over each other to produce lands and drifts to form the oceans.

At a very early there was a supercontinent, Pangaea that slowly shows the formation of the current continent by the movement of the tectonic plates. These solid hard rocks of the earth layers allowed the formation of the various land formations.

The seafloor spreading is the best evidence that supports the tectonic plate theory that described the formation of the oceanic structures including the trenches and basins. The geological structures of the ocean floors supported the theory.

Therefore, option A. evidence of seafloor spreading supported the plate tectonic theory.

traps heat. Many scientists hypothesize that human activities are accelerating this
process, resulting in a global warming trend. What human activity is believed to have an
adverse effect on the natural process pictured here?

Answers

Answer: c. burning of fossil fuels.

Explanation:

Carbon Dioxide and other greenhouse gases like it are the reason some of the sun's heat is trapped in the atmosphere instead of leaving back into space. Any process which increase the amount of carbon dioxide in the atmosphere therefore can increase global warming.

One of the major human activities that involves releasing carbon dioxide is the burning of fossil fuels. We use fossil fuels for many things including producing electricity and driving. When this happens we release a lot of carbon dioxide into the atmosphere thereby making global warming worse.

What type of asexual reproduction is shown in the image below?

A)Binary Fission

B)Spores

C)Budding

D)Vegetative reproduction

Answers

It's budding or vegetative productioon it's one of them i think tell me if i am wrong

The type of asexual reproduction shown in the image below is Option C) Budding.

Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. For example, the small bulb-like projection coming out from the yeast cell is known as a bud. Since the reproduction is asexual, the newly created organism is a clone and excepting mutations is genetically identical to the parent organism. Organisms such as hydra use regenerative cells for reproduction in the process of budding.

In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.Internal budding or endodyogeny is a process of asexual reproduction, favored by parasites such as Toxoplasma gondii. It involves an unusual process in which two daughter cells are produced inside a mother cell, which is then consumed by the offspring before their separationBudding, in biology, a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. In some species, buds may be produced from almost any point of the body, but in many cases budding is restricted to specialized areas. The initial protuberance of proliferating cytoplasm or cells, the bud, eventually develops into an organism duplicating the parent. The new individual may separate to exist independently, or the buds may remain attached, forming aggregates or colonies. Budding is characteristic of a few unicellular organisms (e.g., certain bacteria, yeasts, and protozoans). However, a number of metazoan animals (e.g., certain cnidarian species) regularly reproduce by budding.
