Microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

What are motor protein?

Motor protein are defined as a group of molecules with the ability to travel across the cytoplasm of animal cells. Molecular motors called motor proteins move along the cytoskeletal filaments of the cell by hydrolyzing ATP. They provide a variety of tasks for biological systems, such as facilitating intracellular trafficking along biopolymer filament tracks and regulating filament sliding during muscle contraction.

Microtubules are defined as the cytoskeleton is made up of tubular-structured polymers, which are present throughout the cytoplasm. Microtubules play a variety of roles in dividing cells, including the construction of the mitotic spindle and axon extension in neurons.

Thus, microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

what is the effect of water temperature on corals from inshore and offshore reefs?

Answers

Answer:

When the water gets too warm, the algae can no longer live inside corals, so they leave. The corals then turn from green to white, called coral bleaching. Climate change has been causing the Earth's air and oceans to get warmer. With warmer oceans, coral bleaching is becoming more widespread.

Explanation:

When the water temperature rises too high, algae can no longer live inside corals and leave. Coral bleaching occurs when the corals turn from green to white.

What are coral reefs?

A coral reef is an underwater ecosystem characterized by corals that build reefs. Reefs are made up of coral polyp territories hosted along by calcium carbonate.

The vast bulk of coral reefs are mainly composed of stony corals, which have polyps that coalesce together.

Coral reefs grow in shallow water with temperatures ranging from 68° F to 97° F. The Indo-West Pacific biogeographic region contains more than 90% of the world's coral reefs.

When the temperature of the water rises too high, algae can no longer live inside corals and must leave. Coral bleaching occurs when corals alter color from green to white.

The Earth's air and oceans are becoming warmer as a result of climate change. Coral bleaching is becoming more common as the oceans warm.

Thus, this is the effect of water temperature on corals from inshore and offshore reefs.

Explanation:

Before 1928, humanity had conquered most of its enemies and people were only limited in lifespan by internal mechanisms being disrupted or failing, such as cancer, genetic errors,viruses, and BACTERIA. But in 1928 by accident a scientist discovered penicillin and finally deaths by bacteria were dropping to the point where in the past a mere cut could mean death by bacterial infection when compared to the present, humanity now doesn’t even consider bacterial infection, and that is all due to the power of penicillin and other antibiotics.

Water is a polar compound because there is a positive hydrogen end and a negative oxygen end, this is caused by an uneven electron distribution

Why did Ibrahim conclude that the dorsal spines were not used to support a hump or to regulate body
temperature?

Answers

Chemical composition of dorsal spines provides information about its function as regulation of body temperature.

The dorsal spines were not used to support a hump or to regulate body  temperature because of the chemical composition of the spines. Ibrahim found that the spines were made up of bones having few blood vessels and were likely wrapped tightly in skin which can't perform the function of thermoregulation in the body.

In order to regulate temperature of the body, more blood vessels are needed and we know that in dorsal spines the structure is bony and less number of blood vessels so we can conclude that chemical composition of dorsal spines provides information about its function as regulation of body temperature.
