Nutrition, Energy, and Biochemical Processes
The absorption and distribution of materials within an organism is a life function known as
Transport
Small changes made within homeostasis to maintain balance
Dynamic Equilibrium
Proteins that are produced when foreign particles enter the body; specifically shaped to fight specific pathogens
Antibody
What are
Adenine (A)
Thymine (T)
Guanine (G)
Cytosine (C)
The 4 nitrogenous bases in DNA
Factors that determine the number (population) and kinds (species) of organisms that can live in an ecosystem
Limiting factors
The breathing rate, heart rate, and blood hormone levels of an individual would directly provide information about that individual's
metabolic activity
A blank feedback takes an organism further from homeostasis.
Positive
This is cancer of white blood cells.
Leukemia
This is the process of making an identical copy of the DNA in a cell.
DNA Replication
This is a map of the relationships between populations in an ecosystem
A food web
Materials are transported within a single-celled organism by the
Cytoplasm
Gland that produces hormones that regulate blood sugar; produces enzymes that break down macromolecules.
Pancreas
Part of plant grows into new plant offspring
Vegetative Propagation
anti-codons; they match up with the codon for the amino acid they're attached to
tRNA
an ecosystem has blank when it has many species and can survive major changes
One primary function of a this is regulating the flow of simple sugars into or out of the cell
cell membrane
Hormone that raises the level of glucose in the blood.
Glucagon
is how body cells (somatic cells) reproduce.
Mitosis
The environment changes gene expression without causing this
Mutations
Define renewable resources and give examples
Can be replaced/“renewed” given sufficient time
Examples: Wind, Solar, Hydropower, Trees (Biomass)
A measure of osmosis on both the inside and outside of the cell membrane
Tonicity
Identify one effect a reduced number of insulin receptors might have on an individual.
Possible Answers: High levels of glucose in the blood/urine. — The person might be diabetic. — Less glucose will go into the cells. — The blood glucose level will not be controlled.
An organelle near the nucleus in the cytoplasm of most organisms that controls the organization of its microtubules and gives rise to the mitotic spindle
Centrosome
Selective breeding requires this among a population.
gene variation
State the Ecological Hierarchy in order
Individual - a singular organism
Population - group of the same species
Community - all of the biotic factors in an area
Ecosystem - all of the abiotic and biotic factors in an area
Biosphere - all of the ecosystems on earth
