A scientist is observing a cell and notices the presence of starch. What does this tell her about the cell? A.
It is an animal cell because starch is the energy storing molecule in animal cells.
B.
It is an animal cell because starch is responsible for protein synthesizing in animal cells.
C.
It is a plant cell because starch is responsible for protein synthesizing in plant cells.
D.
It is a plant cell because starch is responsible for cell building in plant cells.
E.
It is a plant cell because starch is the energy storing molecule in plant cells.

Heyllo,

E.

It is a plant cell because starch is the energy-storing molecule in plant cells.

Plant cells use starch to store extra sugar, whereas animal cells use glycogen.

Here is my notes on carbohydrates (you don't need to see it unless you need an explanation).

All carbohydrates contain carbon, oxygen, and hydrogen atoms.

When you eat anything plant-based, your body uses a complex process called to turn carbohydrates into energy.

There are three types of carbs;

Monosaccharides: 1 sugar molecule

glucose, fructose, galactose.  

disaccharides: 2 sugar molecules linked together.

maltose, sucrose, lactose.  

polysaccharides: many sugar molecules linked.

starch***, glycogen*, cellulose**.

*how animals store glucose. They keep the glycogen in their liver cells.

** The structure of plant cell walls.  

***plants store extra sugar in the form of starch.

i believe it is 40–40–20%

explanation:

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
