Describe how changes in an ecosystem can affect organisms that live there..

Well it really depends on what kind of change there is. For this I'll use a drought as an example. If a drought occurs in an area the plant life and vegetation will start to die off in that area. From there, primary consumers would run out of food. then secondary consumers, and so forth and so on. it'd be like putting a cow in a field of dirt with no food and a large bucket of water. Eventually the cow will die of starvation. Now apply this to all of the animals in that ecosystem.

lutik1710 [3]

Endoplasmic reticulum serves as transpiration area. The correct option is B.

<h3>What is endoplasmic reticulum?</h3>

The endoplasmic reticulum (ER) is a large, dynamic structure in the cell that performs numerous functions such as calcium storage, protein synthesis, and lipid metabolism.

The ER's various functions are carried out by distinct domains, which include tubules, sheets, and the nuclear envelope.

The endoplasmic reticulum can be smooth or rough, and its function is generally to produce proteins that allow the rest of the cell to function.

Ribosomes, which are small, round organelles that make proteins, are found in the rough endoplasmic reticulum.

Thus, the correct option is B.

Tin, because it has five energy levels with four electrons in the fifth level .

Explanation:

Tin has an electronic configuration as

1s2,2s2,2p6,3s2,...........4d10, 5s2,5p2

They have four valence electrons in their outer shell

Among the four diagrams given Tin is least reactive because the atomic radius of tin is largest among all four options. Due to large atomic radius electronegativity decreases and hence Tin is the least reactive element among Neon, Chlorine, gallium and tin.

The electronegativity of an element is its tendency to complete its octet by attracting electrons towards itself. Also tin is at the lowest place in the periodic table among all the four mentioned elements, its ionization energy is also low hence less electronegative and least reactive.
