How the combination of electrons, protons ans neutrons results in the neutral charge of an atom?

Answers

Answer 1

Answer: Hi :D
Neutrons are neutral so they have no charge. Electrons have a negative charge and protons have a positive charge.
For an atom's charge to be neutral there has to be an even amount of protons and electrons in the atom.

What effect can fertilizer runoff have on an aquatic ecosystem?a. increased plant growth leading to a decrease in fish populations
b. increased plant growth leading to an increase in fish populations
c. decreased plant growth leading to a decrease in fish populations
d. decreased plant growth leading to an increase in fish populations

Answers

a. increased plant growth leading to a decrease in fish populations. Fertilizer runoff degrades aquatic system by promoting growth of algae, phytoplanktons and other aquatic plants. A phenomenon called 'algal bloom' will take place, increasing oxygen consuming bacteria and lessening the available oxygen for plants and animals in the area.

Answer:

it would be A

Cytoskeleton

a complex,network of interlinking filaments made of protein

present in the cytoplasm of eukaryotic cells

helps cells keep their shape and internalorganization
allows cells to complete essential functions like division and movement by providing support

Vacuole:

a space of cell without cytoplasm filled with fluid
storage and disposal are its roles
storefood or other nutrients for cellular need
store waste and toxic products

A light microscope uses focused light and lenses to magnify an object. Light microscopes come in several forms. (1) Simple light microscopes use a single lens to magnify an object and cannot reach high magnification just like a handheld lens whose highest clear magnification in the best conditions is 25x. (2) Compound light microscopes use two sets of lenses - an objective lens and an eye piece. This is the type of light microscope whose magnification power reaches between 1000x and 2000x.
