Answer:

(08) and (32)

Explanation:

To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.

The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.

What are convergent boundaries?
boyakko [2]

Answer:

Explanation:

A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.

Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]

Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence

Breeding horses. People want prized racehorses to mate with their females so they can maybe have fast prize winning horses as well. People also use artificial selection in choosing fast horses to make fast colts that can later on race. So they want the best qualities in the colts so they mate the best horses.

Hope this helps :)

The enzyme will be transported to either the cytoplasm or the mitochondria to perform the functions.

<h3><u>Explanation:</u></h3>

Cellular respiration is the process by which a living cell burns nutrients like glucose, fats, or even proteins to produce energy molecules namely ATP to perform its daily works. This cellular respiration, which is mainly aerobic, takes place both in cytoplasm and mitochondria.

The glycolysis part of the cellular respiration takes place in the cytoplasm. The enzymes that take part in the glycolysis cycle reaches to cytoplasm from ribosome to perform.

But both the Kreb's Cycle and the Electron Transport chain take place in mitochondria. Kreb's Cycle takes place in mitochondria matrix and ETC takes place in inner mitochondrial membrane. Although ETC isn't a enzymatic process, Kreb's Cycle is fully enzymatic and the enzymes reaches from ribosomes inside mitochondria by transporters.
