Biology Section 51: Sexual Reproduction & Meiosis

solvent – dissolving substance in a solution
epithelium – animal tissue consisting of one or more layers of cells that have only one free surface, because the other surface adheres to a membrane or other substance
When does a cell rely on fermentation for its energy needs? – A cell rely on fermentation for its energy needs when the cell has no oxygen.
Fermentation – Process in which NAD+ is regenerated, allowing cells to maintain glycolysis in the absence of oxygen.
How do you calculate molarity? – To calculate molarity:
1. Calculate the number of moles of solute present.
2. Calculate the number of liters of solution present.
3. Divide the number of moles of solute by the number of liters of solution.
DNA replication – semiconservative process that make a duplicate copy of an organisms DNA

10.2 – Second phase of mitosis in which the chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere

flagellate – a protozoan that propels itself with a flagellum
monosaccharide – the simplest carbohydrate, also known as a simple sugar, active alone or serving as a monomer for disaccharides and polysaccharides
vaccination – A procedure that presents the immune system with a harmless variant or derivative of a pathogen, thereby stimulating the immune system to mount a long-term defense against the pathogen.
Which of the following dyes will bind only to double-stranded DNA?
How does the small size of a red blood cell mean that it's adapted to it's purpose? – It means that it has a large S/A:Volume ratio so it can exchange oxygen more quickly.
Motor protein – type of protein attached to microfilaments and microtubules; used in cell movements.
Metabolic Reaction – Reactions that occur inside living organisms
ATP – Adenosine Triphosphate, the major energy-carrying molecule of the cell.
resting potential – The membrane potential of a neuron that is at rest.
radial symmetry – An arrangement of the body parts of an organism like pieces of a pie around an imaginary central axis. Any slice passing longitudinally through a radially symmetrical organism's central axis divides it into mirror-image halves.
Which оf the fоllоwing dyes will bind only to double-strаnded DNA?
asexual reproduction – Process by which a single parent reproduces by itself. ie..unicellular cell divides to form new cell
carbohydrates – main source of energy in organisms molecule has twice as many hydrogen as carbon
Receptor – Membrane protein that triggers a change in cell activities after it binds signaling molecules
How can stem cells be used? – Because they have the ability to develop into any cell, they could be used in a number of ways. Most importantly, they could replaced damaged tissue, which will treat patients with many diseases, including Parkinson's.
