what would you call this set of alleles: bb
Homozygous recessive
200
The grouping of cells that contain DNA, cytoplasm, ribosomes, and a cell membrane, but no other membrane-bound organelles.
Prokaryotic or prokaryotic cell
200
Enzymes reduce this in order to speed up a reaction.
Activation energy

A students observes a cell where the chromosomes appear to be pulled apart by spindle fibers. These two final steps would come after this.
Telophase and cytokinesis
200
A biomolecule that serves as a fast source of energy?
Carbohydrates

Any inherited trait that increases an organism's chance of survival is known as this.
Adaptation

This RNA is transcribed from a section of DNA and later leaves the nucleus in order to be translated into an amino acid chain.
mRNA

movement of ions, and molecules across cell membranes without the need for energy input
Passive transport
300
Water molecules have attractive forces to one another and are held together by these types of weaker bonds
Hydrogen bonds
300
The stage in mitosis where DNA gets replicated
S phase

What type of solution has more solutes on the outside of the cell?
Hypertonic
400
This process produces four genetically unique cells, each with half the number of chromosomes as in the parent
meiosis
400
A species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
Keystone species
400
This is the process by which organisms break down glucose, without the use of oxygen, to create ATP
Anaerobic cellular respiration

There are three organelles found in a plant cell but not an animal cell. name 2
Cell wall, large central vacuole, and chloroplast
500
The process by which water moves through the cell membrane to balance out a high concentration of solutes.

Sickle cell anemia is a recessive disease. If you cross two parents with the alleles Aa x Aa, what are their children's chances of having sickle cell anemia?
25% have sickle cell
