The concept required to solve this problem is quantization of charge.
First the number of electrons will be calculated and then the total mass of the charge.
With these data it will be possible to calculate the percentage of load in the mass.

Here Q is the charge, n is the number of electrons and e is the charge on the electron

Replacing,


According to the quantization of charge the charge is defined as product of the number of electron and the charge on the electron
The total mass of the charge is

Here,
m = Mass of the charge
n = Number of electrons
= Mass of the electron

Replacing we have


Correct answer choice is :
A) True
Explanation:
Lipoproteins are essentially a hub full of fat and cholesterol, along with a lipid layer that includes proteins named apolipoproteins. There are many kinds of lipoproteins, but the two most prominent ones are called Low-Density Lipoprotein and HDL.LDL particles are seldom related to as bad lipoprotein because of concentrations, dose-related, associated with atherosclerosis change. High-density lipoproteins (HDL) get fat molecules from the body's cells and take it back to the liver.
Specific gravity is the ratio between the substance's density and the density of water. Being a ratio of dimensions with same units of measure, this value is unitless.
The substance or objects sinks in water if its density is greater than that of water. On the other hand, it floats if its density is lesser compared to that of water.
Having said so, the substance or object sinks in water if the specific gravity is greater than 1 and floats if the specific gravity is lesser than 1.
sinks: SG > 1
floats: SG < 1
Answer:
Ok I’m not pretty sure but I think it’s C but look for more answers first before you put C because I don’t want you to get it wrong. :)
Explanation:
Answer:
4. since they are based on natural ecosystems have often resulted in alteration and destruction of natural systems
Explanation:
this is because agriculture leads to loss of habitats, loss of nutrients from the soil, it has also lead to the use of chemicals which are harmful to the environment as pesticides, and all this destroys natural systems
