Answer:

Your answer is below

Explanation:

The first picture shows a cell membrane inside the protein there is a protein that needs energy to carries a molecule. Then, picture a is active transport, it needs energy.

The second picture shows a cell membrane that is that is eating a molecule then this picture shows a endocytosis process. It needs energy.

The third picture shows a cell membrane and a protein inside it, but it doesn't needs energy to carries a molecule, then this picture is an example of facilitated diffusion.

The fourth picture shows a membrane that is excreting wastes or molecules, then this picture is exocytosis. It needs energy.

Place the steps involved in burning coal to create electricity in the correct order.

butalik [34]

Answer and Explanation:

Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area.
Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam.
Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines.
Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.

________________ is the name given to the clock signal that occurs evenly spaced time durations during which data signals are se

Ipatiy [6.2K]

Answer;

Bit clock

-Bit clock is the name given to the clock signal that occurs evenly spaced time durations during which data signals are sent in synchronous transmissions.

Explanation;

The term "bit clock" is used to describe a one cycle per sample "square wave" signal used for internal synchronization within digital audio equipment.

-In synchronous transmission data signals are sent along with a clock signal which occurs at evenly spaced time duration referred to as the bit time. On the other hand, in asynchronous Data signals are transmitted without an associated clock signal. The time spacing between data characters or blocks may be of arbitrary duration, meaning the spacing is not standardized. Therefore, frames require start and stop indicator flags.

What is the natural polysaccharide whose repeating structure can be symbolized by glcuaβ(1→3)glcnac, with these units connected

Nina [5.8K]

<h3>Answer;</h3>

The polysaccharide is Hyaluronic acid

<h3>Explanation;</h3>

Hyaluronic acid is a natural polysaccharide which is in the class of glycosaminoglycans that is mostly found in neural, connective and epithelial tissues in human body.
Hyaluronic acid is made up repeating units of glucuronic acid and N-acetylglucosamine that are joined by alternating β- 1,4 and β- 1,3 glycosidic bonds.
It is a linear polysaccharide and is the only glycosaminoglycan that lacks sulfate atoms in its structure.
