1
Q

Pathogens

A

Disease causing agents such as bacteria and viruses

2
Q

Bacteria

A

Single celled organisms responsible for things such as strep throat, staph infection, pneumonia. Treated with antibodies

3
Q

Viruses

A

Replicate in the host’s cells. Common cold, flu, AIDS, herpes. Can’t be treated with antibodies

4
Q

Gametes

A

Reproductive cells. Haploids, half as many cells as normal cells (diploids).

5
Q

Meiosis

A

Gametes are created

6
Q

DNA

A

Genetic code, combination of nucleotides. Shape of double helix

7
Q

Gene

A

Unit of inheritance contained within an individual’s DNA

8
Q

Alleles

A

Varieties of genes, two in each gene from each parents. Same are homozygous, different are heterozygous

9
Q

Genotype

A

Genetic makeup including dominant and recessive genes

10
Q

Phenotype

A

How genes are expressed in physical characteristics

11
Q

Prokaryotic

A

No nucleus

12
Q

Nucleus

A

Contains genetic material of cell

13
Q

Cytoplasm

A

Outside nucleus, surrounds other cell structures

14
Q

Ribosomes

A

Produce proteins

15
Q

Endoplasmic reticulum

A

Synthesis of proteins and fats

16
Q

Golgi apparatus

A

Packages proteins for use

17
Q

Lysosomes

A

Manages cell waste

18
Q

Centrosomes

A

Guide cell’s reproduction

19
Q

Cellular respiration

A

Mitochondria processes sugar and oxygen to make energy, water, and carbon dioxide

20
Q

Chromosomes

A

Tightly coiled threads of DNA

21
Q

Biosphere

A

Zone of earth where life naturally occurs, deep crust to lower atmosphere

22
Q

Biome

A

Major life zone of interrelated species bound together by similar climate, vegetation, and animal life

23
Q

Producers

A

Autotrophs, make food via photosynthesis

24
Q

De composers

A

Saprotrophs, break down organic matter and release minerals

25
Q

Consumers

A

Heterotrophs, consume other organisms divided into: primary (herbivores), secondary and tertiary (omnivores and carnivores)

26
Q

Classification of living things

A

Domain, kingdom, phylum, class, order, family, genus, species

27
Q

3 domains

A

Eukaryota - living things with nucleus

Bacteria and archaea - single celled organisms without nucleus

28
Q

Monera

A

Bacteria. Prokaryotic cells, most primitive

29
Q

Protista

A

Simplest eukaryotes

30
Q

Fungi

A

Decomposers
