Biology Chapter 1: Biology: Exploring Life

nucleus – Control center of the cell, contains DNA
make many more ATP – What happens to the molecules formed during glycolysis when oxygen is available?
carnivores – Organisms that eat only organisms other than plants. (Meat eaters)
gene splicing – type of gene recombination in which DNA is broken and recombined using lab techniques
lysosome – membrane-bound organelles that contain enzymes, defend the cell and break down damaged or worn out cell parts
Evolution – Over many generations the characteristics of a population change. Many species that existed in the past but are now extinct actually developed into species that exist today.
(T/F) A nephron is situated such that the loop of Henle runs through he medulla. – True
Concentration – the amount of the substance (solute) dissolved in a unit of the other substance (solvent)
The habitat of an organism includes – biotic (living) factors such as population and food source, and abiotic (non-living) factors such as weather, temperature, soil features, sunlight).
excision of the epididymis
Mitotic phase – the phase of the cell cycle which includes mitosis and cytokinesis
prokaryotic cell – cell that lacks a true nucleus but contains DNA, ribosomes, cytoplasm, and a cell membrane
b) the population increased rapidly and then leveled off –
White blood cell – Blood cells that perform the function of destroying disease-causing microorganisms
Cladogram – A branching diagram that illustrates taxonomic relationships based on the principles of claudistics
excisiоn оf the epididymis
Fatty acid – The monomer in a lipid is a(n) _____ ____.
300. Are basic development patterns similar among all animals? – No.. They vary greatly. Sometimes the first two cells divide in unequal sizes and each cell becomes a specific part of the animal (like worms). Sometimes the first two cells are similar (like sea star)
intermediate – One of the compounds that form between the initial reactant and the final product in a metabolic pathway, such as between glucose and pyruvate in glycolysis.
Organ system – A group of organs working together to perform a particular function. Example – The digestive system includes a number of organs (mouth, esophagus, stomach, small intestine, liver, gall bladder, pancreas, large intestine) all dedicated to breaking down food, absorbing the nutrients, and getting rid of the indigestible waste.
