Which component of a plant makes the cell walls around plant cells tough and allows branches, stems, and leaves to be strong

Vsevolod [243]

<h3><u>Answer;</u></h3>

Cellulose

<h3><u>Explanation</u>;</h3>

Cellulose is a polysaccharide and the most abundant organic compound on the Earth's surface.

<em><u>It is an important organic molecule due to its strong structure which provides a wide variety of functions. </u></em>
<em><u>Cellulose is a major component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches very strong.</u></em>
The molecules of cellulose are arranged such that they are parallel to each other joined by hydrogen bond. this arrangement forms long structures that combine with other cellulose molecules producing a strong support structure.

Americans eat too much salt (NaCl). A healthy adult should eat no more than 6 g of salt in one day. Use this information to answ

Rufina [12.5K]

Answer:

a. 58.5 g/mol

b. 0.1 mol

Explanation:

a.

The molar mass of Na is 23.0 g/mol. The molar mass of Cl is 35.5 g/mol. The molar mass of NaCl is:

M(Na) + M(Cl) = 23.0 g/mol + 35.5 g/mol = 58.5 g/mol

b. A healthy adult should eat no more than 6 g of salt in one day. The moles corresponding to 6 g of NaCl are:

6 g × (1 mol/58.5 g) = 0.1 mol

Scientists observe that iron compounds are able to bind to nutrients in waterways experiencing eutrophication. Which change will

Anettt [7]

(1) Fewer microorganisms will grow on the surface of the lake if iron compounds are added to a lake with an overabundance of nutrients. Hence, option 1 is correct.

(2) Fracking means using water and chemicals at high pressure to open up fissures to access oil and gas resources. Hence, option 2 is correct.

<h3>What are microorganisms?</h3>

An organism that can be seen only through a microscope.

Iron is a natural capping agent which can enhance sediment P binding capacity, thus reducing P availability and shifting a lake from an algal to a macrophyte dominated state. Iron could, however, also impose toxic effects on the biota.

Fracking is the injection of a fluid at high pressure into an underground rock formation to open fissures and allow trapped gas or crude oil to flow through a pipe to a wellhead at the surface.

This technique is used in natural gas and petroleum production.

Pls help! Polonium has a large, unstable nucleus. Through which process is it most likely to become stable?

Stella [2.4K]

The process through which Polonium is most likely to become stable is: B. alpha decay.

An unstable element refers to a chemical element that lose particles because its nucleus contain an excess of internal energy (neutron or proton).

This ultimately implies that, an unstable element is radioactive in nature.

In Science, some examples of an unstable element are:

Tritium.

Bismuth-209 .

Xenon.

Polonium.

Polonium is a chemical element with a large, unstable nucleus.

Basically, the most stable isotope of Polonium is Polonium-209, which typically undergoes an alpha decay to form lead-205 and the emission of an alpha particle.

⇒ $^{209}_{84}Po$ ----> $^{205}_{82}Pb \;+\; ^{4}_{2}\alpha$

In conclusion, we can deduce from the above chemical equation that Polonium is most likely to become stable through an alpha decay.
