The goal of basic science is

to teach you basic fundimentals of biology

What is the basic function of a cell membrane

The basic function is to control which substances enter and leave the cell.

What is the main function of cellulose in plants

Provide physical support

What is the main function of starch in plants

The main function of starch in plants is to store energy.

Which chemical bond most likely stores the most energy

C=c

Double carbon-carbon bond

What kind of molecule is formed when many disaccharide molecules are combined

A combination of many disaccharides will yield a polysaccharaide, such as starch or cellulose

What do bacteria have in common with the cells of other living organisms

They have ribosomes.They contain cytoplasm.

Some things bacteria have in common with cells of other living organisms is they both have chromosomes, they both have organelles and a nucleus, and are alive.

they have a cell membrane

What macromolecule is made up of nucleic acids

DNA and RNA are made up of nucleic acids.

Why does water roll off the surface of a leaf

because the leaf is non polar

or

Because the leaf is coated in lipid molecules

Which would provide the body with most energy

Incorrect, it's actually "Breaking bonds in a Polysaccharide" Tested.

(Apex.)

Which scientist was responsible for disproving the theory of spontaneous generation

Louis pasteur
Louis pasteur

What is the purpose of ethical guidelines for the handling of experimental subjects

The purpose of ethical standards for the treatment of experimental subjects is to assure the safety and well-being of all living things included in the study.

What was Rudolf Virchow trying to prove through his work

Spontaneous generation does not happen.

Which adds evidence to the idea that the cell is the basic unit of life

Many organims are made of one cell.

A sodium atom that has lost an electron comes near a chlorine atom that has gained an electron What happens

they form an ionic compound

What describes a chemical reaction taking place

Hydrolysis of disaccharides

What is the purpose of using multiple control groups in experiments

Speaking from a degree in science and speaking scientifically, the purpose of having multiple control groups is so you can make sure that your experiment is completely valid, and to determine whether or not your experiment is true to your hypothesis because in your hypothesis it pretty much states what the experiment is about, but if your experiment has gone wrong in any way you want to make sure that if you have all your control groups, you can redo the experiment and still have your control groups.

apex!:)- to help control for factors that aren't being tested but might affect results.

What is the goal of a statement of the purpose

To indicate what is expected to be accomplished in doing an experiment

What kind of molecule is formed when many disaccharide molecule is combined

cellulose:)

Which best describes the nucleus of an atom

It is the part of the atom with the greatest mass.

Look at the protein below. Which could be its function

Forming tendons. ;)

What do all cells have in common

They all Contain DNA

Look at the diagram below. Which best describes the structure labeled X in the diagram

A membrane protein is transporting substances. APEX
