The correct answer is - discontinue the use of irrigation systems.

There has been multiple suggestions as two how the Aral Sea can be saved because it is in a situation where its waters have retreated significantly, as things go it will be totally dried out very soon in the future.

The stopping of the usage of the irrigation systems is not one of the suggested measures though, even though that is the biggest reason why the Aral Sea is drying out, because lot of water is used for irrigation, and its tributaries bring in less water to it.

The big problem is that the economy is heavily dependent in this region on the agriculture, and the region is naturally very dry. So if the irrigation is stopped, the agriculture will crumble, and millions of people will lose their only income.

What clues could you use to help determine whether movement of oslutes through the apicl and basolateral cell membranes is passi
Setler79 [48]

Answer:

Clues that can be used to determine whether the movement of solutes through the membrane is passive or active could be the molecule size, membrane potential, and the presence/absence of membrane protein.

Explanation:

Solutes transport through the cellular membrane depends on the solute size, membrane potential, and the presence/absence of integral membrane protein.

There are two types of transport: Active and passive.

-        Passive transport: It does <u>not need energy</u>; it is driven by a chemical potential gradient. <u>Small molecules</u> with no charge are transported through the membrane in a gradient favor, from a high concentration region to a low concentration region. There are two types of passive transport: <em>By simple diffusion</em> (small molecules pass through the membrane by themselves) and by <em>facilitated diffusion</em> (molecules are helped by integral membrane proteins to pass through the membrane). In facilitated diffusion, the helping protein can be a <u>channel protein</u> (hydrophilic pores that allow the molecule to pass with no interaction) or a <u>carrier protein</u> (proteins with mobile parts that suffer modification as the molecule pass to the other side).

-         Active transport: It <u>does need ATP energy</u> to pass the molecule through the membrane, as they have to <u>move against the electrochemical gradient</u>. This kind of transport is always mediated by a <u>carrier protein</u>. These proteins join with the molecules and suffer changes as they pass the solute to the other side of the membrane. An important example of this kind of transport is the sodium-potassium bomb.

Which structure has the active sites where the heads of the thick filaments will bind?
Gre4nikov [31]
THE ACTIN has the active site to which the heads of the thick filament will bind.
The muscle is made up of two major protein fibers, which are the actin and the myosin. Muscle contractions occur when myosin and actin slide over each other in a series of repetitive events. The protein actin has a thin structure and is abundant in eukaryotic cells while myosin is a thick filament.
