Regulate most cell activity

A solution that has pH of 5.2 is:

The cell theory does NOT include:

This disposes of cell waste

Osmosis is:

A cell, placed in this type of solution, will shrink:

When atoms share electrons, it is this type of bond:

This organelle houses the Electron Transport Chain

An electromagnetic attraction between two ions is this type of bond:

The heterozygote is a blend of the two parent phenotypes

This is composed of a lipid bi-layer and protein channels

What is measured in an experiment

Monomers of proteins are:

An allele that is always expressed over another allele

tRNA brings the correct amino acid anticodon to the ribosome to create a protein chain

In chemical reactions, enzymes lower:

Adenine pairs with this in RNA

This is the cell's delivery system

A trait carried on the sex chromosomes

A water molecule contains:

Two dominant traits are equally expressed

What is released during cellular respiration?

Division of cells resulting in the creation of (4) gametes

Adenine pairs with this in DNA

The physical attributes of an organism

This is the knowledge gained from careful observation

Enzyme splits DNA molecule, free nucleotides pair correctly, creating 2 identical DNA strands

The cell membrane separates into two cells; each with a nucleus and some organelles

This type of cell has a nuclear membrane

This solution has more water than dissolved solutes:

Meiosis produces:

He was the first to see living cells under a microscope

Cytosine always pairs with

A red (RR) flower is crossed with a white (WW) flower. All offspring are pink (RW). This is:

These two determined that all plants and animals are made from cells

Made of only one cell

These are used for cellular locomotion

Chromosomes line up in the middle of the cell

Two new nuclei form and the cytoplasm begins to pinch in

Active transport is the movement of molecules from:

This is responsible for assembling proteins

This stores water or chemicals for later use

A cell, placed in this type of solution, will swell:

In translation, the appropriate tRNA anticodon to pair with the mRNA CUA is:

Determined that all cells come from pre-existing cells

Chromosomes are pulled apart and move to opposite sides of the cell

The variable changed in an experiment

Contain genetic information

This is responsible for controlling all cell activity

Movement of water across a semi-permeable membrane

Mitosis produces:

Photosynthesis uses sunlight to convert carbon dioxide and water into:

This compound removes Hydrogen ions (H+) in a solution.

A non-sex chromosome

mRNA "reads" and copies the DNA

This compound releases Hydrogen ions (H+) in a solution.

An organism has the trait, but it is not expressed

When genetic information is copied

Nuclear membrane disappears and chromosomes coil up into x-shape

A solution has more salt than water. This type of solution is:

This is an educated prediction

Movement of any particle from area of high concentration to area of low concentration

A group of 3 nucleotide bases

This type of cell has NO nuclear membrane

Energy is released from ATP when:

How a hypothesis is tested

Store Energy

Make up cell parts
