Answer:

Microfilaments, Intermediate filaments and microtubules

Explanation:

Three distinct elements make up the cytoskeleton in eukaryotic cells are:

1. Microfilaments or actin filaments which are composed of actin proteins. The functions of those filaments are: muscle contraction (myosin heads move “walk” on actin filaments), the movement of the cell,  intracellular transport, maintaince of the cell shape..

2. Intermediate filaments which can be made of vimentins, keratin, lamin, desmin… Their functions are: the maintenance of cell shape, anchoring organelles, structural components of the nuclear lamina, cell-cell and cell-matrix junctions…

3. Microtubules are filaments polymers of alpha and beta tubulin. Their roles are in intracellular transport (associated with motor protein dyneins and kinesins),  formation of the axoneme of cilia and flagella, formation of the mitotic spindle.

Marianna [84]

Answer:

Symbiosis and decomposers.

Explanation:

The ants feed on both plants and insects so we can say that ants are omnivorous. They make a symbiotic relationship of mutualism with fungi such as mold which helps the ants to breakdown the cellulose of plants whereas plants provide habitat to fungi. The bacteria feeds on the dead body of ants and release nutrients by performing the function of decomposition so bacteria acts as decomposer so in that way these four organisms interact with each other.

What drug or drug class inhibits mobilization of free fatty acids from peripheral tissues?
soldier1979 [14.2K]
The drug is: Niacin, or nicotinic acid (vitamin B3, ou PP)  (do not confuse with nicotine)

Nicotinic acid, or niacin, is known for its normolipidemic properties since the 1950s. It was the subject of the first trial of cardiovascular prevention by intervention on the lipidic factor, the coronary drug project (CDP). Despite significant side effects, mainly flushing, it has since been used, mainly in the United States, as a treatment for mixed hyperlipidemias, thanks to its hypotriglyceridemic effect for the increase of HDL-cholesterol.

Explanation;

-Surface mining is a method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying.

-The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes.The environmental effects of surface mining include;

  • Habitat destruction
  • Soil erosion
  • Air pollution from dust particulates
  • Pollution (especially from sediments)
  • All surface mining techniques negatively affect the environment, though some methods are more damaging than others.
