The microtubule depolymerizes will happen when gtp hydrolysis occurs on a tubulin molecule at the plus end of a microtubule protofilament before another tubulin molecule is added.
The harmful effects of microtubule depolymerizing and polymerizing substances lead to apoptosis after mitotic arrest, and these effects are more pronounced in cancer cells than in healthy cells. In reality, a number of microtubule inhibitors are often used in clinical settings.
Microtubules provide a variety of purposes. For instance, they are crucial parts of cilia and flagella and provide the structured, rigid components of the cytoskeleton that provide shape to many cells (cellular locomotory projections). During cell division, they take role in the development of the spindle (mitosis).
Three different spindle microtubule types—kinetochore microtubules (green), astral microtubules (blue), and interpolar microtubules—frame the spindle's overall shape (red). The fast-growing (plus) end and the slow-growing (minus) end are the two different ends of the polarised structure known as microtubules.

When sea levels rise as rapidly as they have been, even a small increase can have devastating effects on coastal habitats farther inland. It can cause destructive erosion, wetland flooding, aquifer and agricultural soil contamination with salt, and lost habitat for fish, birds, and plants. What happens to biodiversity in coastal communities as the sea level rises?
Biodiversity decreases because plants and animals adapted for fresh water will not survive and reproduce in a different environment.
What is sea rise?The term sea rise has to do with a situation in which there is a sudden increase in the sea level. This could lead to a sudden overflow of water into rivers lakes and ponds.
We know that sea water is salty, there is excess salt concentration in a sea water while fresh water does not contain salt at all. In these cases whereby there is an overflow of seawater, the water carries salt along with it. This implies that land and fresh water could become contaminated with this salt and that would have catastrophic effects on these ecosystems.
Since fresh water organisms can not tolerate a sudden increase in the concentration of salt in the ecosystem, biodiversity decreases because plants and animals adapted for fresh water will not survive and reproduce in a different environment.

Suppose that zonosemata flies whose own wings had been clipped and reattached were attacked more frequently than untreated zonosemata flies. How would this result have affected the reliability of the other experimental results?.
Suppose that Zonosemata flies whose own wings had been clipped and reattached were attacked more frequently than untreated Zonosemata flies. All results for the experimental groups involving wing surgery would be invalid.
It has been demonstrated that jumping spiders avoid attacking zonosemata insects because of their mimicking technique. Wings from Zonosemata vittigera were transplanted onto houseflies, and vice versa, as part of the experiment.A wing design that resembles legs and a wing-waving display on the tephritid fly Zonosemata vittigera replicate the aggressive territorial behaviours of jumping spiders. When jumping spiders are stalked by zonosemata flies, the spiders show back and retreat as a result of the display. It has been demonstrated through wing transplant studies that effective imitation requires both the wing pattern and wing-waving displays.The tephritid fly Zonosemata vittigera has dark bands on its wings, which it may wave to avoid predators, particularly scurrying spiders.To learn more about Zonosemata.

what are the terms that best identify monomers of lipids
Lipids don't have monomers but their basic building blocks are fatty acids and glycerol.
Monomers, the smallest building blocks of macromolecules, are linked by covalent bonds to form bigger polymers. The polymer is more than the sum of its parts because it develops new properties.With the release of a water molecule, a monomer unites with another monomer to form a covalent bond.Since there is no base building block that is covalently linked to create the polypeptide, lipids lack monomers. Instead, lipids are made up of a variety of different building blocks that work together to form the polypeptide. These building blocks include glycerol, fatty acid chains, and phosphate groups, all of which are present in varying amounts and structures. For instance, a triglyceride is made up of glycerol and three fatty acid chains. However, some lipids, such as cholesterol, lack even these fundamental elements.Hence, lipids are made up of fatty acids and glycerol.

by describing the model that you created.
The lock and key model states that the active site of an enzyme precisely fits a specific substrate.
The induced adaptation model states that upon substrate binding, the enzyme's active site undergoes a conformational change that improves adaptation. The lock-and-key model is a model of enzyme-substrate interaction that suggests that the enzyme and substrate have specific complementary geometries that fit snugly together. Enzymes are very specific.
Must bind to a specific substrate before it can catalyze a chemical reaction. The key-and-key model, also called Fisher theory, is one of two models that describe the interaction of enzymes and substrates.

Answer:
Consider one of the procedures where amylase and starch are reacting. If there is strong amylase activity and it is breaking down starch, then you would assign an enzyme activity level of Three.
Explanation:
To evaluate the enzyme activity you might observe the amounts of starch remaining in a solution or the enzyme activity. Both of them can be done qualitatively by adding substances such as iodine to the sample, which will express, through different degrees of the blue color, the enzyme activity level. So,
no enzymatic activity ----------------> level 0
low enzymatic activity ---------------> level 1
moderate enzymatic activity ------> level 2
High enzymatic activity --------------> level 3
In the exposed example there is a strong amylase activity, breaking down starch, which means that there is a very low level of starch and high level of enzymatic activity.

A raindrop of almost pure water lands on a microbe. Mechanosensitive channels, activated by osmotic pressure, are used by microbes to reduce their internal solute concentration by letting solutes out.
In microorganisms, Mechanosensitive channels are very crucial as they play a significant role in different cellular functions. These channels are triggered by the difference in osmotic pressure in cells.
Different cellular functions performed by them include fluid homeostasis, transfer or expression of genetic information, cell adhesion, cell division, and migration.
Moreover, these channels also make a response to membrane tension by changing their conformation.
