social insects |
any of numerous species of insects that live in colonies and manifest three characteristics: group integration, division of labour, and overlap of generations.
Example: all termites (Isoptera) and ants (Formicidae) and by various bees and wasps (Hymenoptera). |
|
|
castes |
the system of dividing society into hereditary(parent to offspring) classes
|
|
|
locomotion |
movement |
|
|
a phylum |
ranks below kingdom but above class |
|
|
mutualistic relationship |
when 2 organisms of different species work together both benefiting for the relationship |

Protozoan Trichonympha digesting wood in the gut of a termite |
These protozoa live in the gut of a termite and actually enable the termite to survive. You see, termites eat wood. However, they are unable to digest a substance called cellulose, which is a major component in all types of wood. The Trichonympha that live in the termite's gut feed on this cellulose. If it were not for these protozoa, the termites would not be able to feed on wood, and they would die of starvation. The Trichonympha, however, keep this from happening and, in the process, feed themselves.

|
Genetic recombination |
is the production of offspring with combinations of traits that differ from those found in either parent.
|
|
|
Asexual Reproduction |
reproduction without sex. In this form of reproduction, a single organism or cell makes a copy of itself. The genes of the original and its copy will be the same, except for rare mutations. They are clones.

Pancreas |
|
|
Mitochondria |
an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
|
|
|
Enzymes |
biological molecules(proteins)that act as catalysts and help complex reactions occur everywhere in life |
|
|
Critical in limiting the size to which an animal cell may grow? |
The ratio of cell structure to cell volume |
|
|
Parasympathetic nerve fibers of the vagus nerve |
The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body.

has two of the same allele (dominate or recessive) |
|
|
Heterozygus |
two different alleles of a gene |
|
|
ATP |
transports energy |
|
