2. Which specific cytoskeletal element is most susceptible to mitotic inhibitors?

Answers

Answer:

microtubules

Explanation:

Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.

What is Microtubules?

The third main component of the cytoskeleton, microtubules, are hard, hollow rods with a diameter of around 25 nm. Microtubules are dynamic structures that constantly assemble and disassemble within the cell, similar to actin filaments.

They have a role in a number of cell motions, including as some types of cell motility, the intracellular movement of organelles, and the division of the chromosomes during mitosis, in addition to determining the shape of the cell.

Microtubules, which typically consist of 13 linear protofilaments arranged around a hollow core, are created when tubulin dimers polymerize to generate them. The head-to-tail arrays of tubulin dimers that make up the protofilaments are organized in parallel.

Therefore, Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.

Three distinguishing characteristics of bacteria are:

Their lack of membrane-bound organelles, Their unicellularity, Their small (often microscopic) size.

What does the term temperature control refer to

Answers

Answer:

the term temperature control refers to Thermostats .....

A device called a temperature controller is used to maintain a target temperature at a given level. The typical thermostat seen in homes is the most basic type of temperature controller.

What are the biological temperature control factors?

The hypothalamus, a region of the brain, controls our body's core temperature. The hypothalamus measures our body's temperature and compares it to the average temperature, which is around 37 degrees Celsius.

The hypothalamus ensures that the body produces and maintains heat if our body temperature falls too low.

Progesterone tends to encourage heat conservation and higher body temperatures, whereas estradiol tends to increase heat dissipation.

Therefore, a thermostat seen in homes is the most basic type of temperature controller.

Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea

Answers

Answer: it would be C e is correct however but that’s already happened. So that wouldn’t be much of a prediction. Hope this helped :)

Explanation:

Thermal expansion of oceanic water leads to a main global sea level rise. So the correct option is D.

What is the greenhouse effect?

Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space. Although it has a considerably smaller impact on global temperatures, greenhouse gases also speed up the pace at which the environment can collect short-wave radiation emitted by the Sun.

More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is emitted after the combustion of fossil fuels. Human-made acts are referred to as anthropogenic actions, and the emission of CO2 is one such anthropogenic activity that adds to the current heightened greenhouse effect.

A greenhouse gas's contribution to the greenhouse effect is determined by how much energy it absorbs, how much it reflects back, and how much of it is present in the atmosphere.

Therefore the correct option is D.
