How do cells control osmosis

By controlling solute concentration inside the cell :D

What is cytoplasm

The protoplasm within the living cell excluding the nucleus is called cytoplasm,which contain all the vital micro structure which is essential for the proper cell functioning.

eg.mitocondria and ribosomes.

It is formed by three things ,cytosol,inclusion,andorganelles.

Where is ATP often produced

Most ATP is produced in the mitochondria organelles inside of cells. The rest is recycled ATP that is used on the surface of cell membranes, the phosopholipid bilayers.

What causes water to be a polar molecule

Unequal sharing of electrons.

What structures are found in animal cells but not in plant cells

what 2 cell parts are found in plant cells but not animal cells

What type of organic macromolecule is formed by polymerization reactions between amino acids

protein

What tool is used to provide a lot of numerical information in a very small area

data table

How do scientists test ideas about chemical evolution

Scientists test ideas about chemical evolution by using computer models.

What is the only thing that should differ between experimental treatments

independent variable

How do cells get ATP the energy currency that does work in living things

Cells make ATP through cellular respiration, which includes glycolysis, the Krebs cycle, and the electron transport chain. It mostly takes place in mitochondria.

What are the factors that are tested by being varied by the experimenter

Independent Variables are the factors that are tested by beingvaried by the experimenter.

What is one disadvantage associated with electron microscopes

living organisms cannot be examined

What portion of the central theory of gene expression occurs at the ribosomes

translation

Dr Proctor is conducting an experiment to see if hummingbirds will visit red flowers more or less often than they visit yellow ones What will be the independent variable in Dr Proctor's experiment

Flower color will be the independent variable in Dr. Proctor's experiment.

What instrument is used to spin liquids to seperate components

Centrifuge is used to spin liquids to separate components.

At some time during their livesall cells must contain DNA

At some time during their lives, all cells must contain DNA.

Can you see most cells with your eyes

No. Most cells are far to small.

What eukaryotic organelles or features might have evolved as a part of or as an elaboration of the endomembrane system

nuclear envelope

The scientific method uses observation and which other process to answer questions-

The scientific method uses observation and experimentation to answer questions

What is the following of a base

A base contain the hydroxyl group (OH)-.
