64
Q

M in MRS. GREN

A

Movement - consciously changing position from one place to another

65
Q

R in MRS. GREN (first one)

A

Respiration - metabolic reaction to produce glucose

66
Q

S in MRS. GREN

A

Sensitivity - The ability to detect stimuli in the internal or external environment and make appropriate responses

67
Q

G in MRS. GREN

A

Growth - Permanent increase in dry mass by an increase in cell number/size

68
Q

R (second one) in MRS. GREN

A

Reproduction - process to make more of the same kind of organism

69
Q

E in MRS. GREN

A

Excretion - The removal of waste products of metabolism

70
Q

N in MRS. GREN

A

Nutrition - Absorption or ingestion of materials for energy, growth, and development - animals need organic compounds, ions, and usually water, while plants need nitrates, phosphates, magnesium potassium, sunlight, and CO2

71
Q

System of calling organisms by their genus and species

A

Binomial System

72
Q

Classification

A

A system that groups organisms that have shared features together - demonstrates how it has evolved and changed over time

73
Q

Levels of classification pyramid

A

Kingdom, Phylum, Class, Order, Family, Genus, Species

74
Q

Organisms are sorted into different categories according to their _____ characteristics

A

Shared

75
Q

Species

A

A group of similar organisms that can interbreed and make fertile babies - about 99.999% of DNA is shared

76
Q

Genus

A

A group of similar organisms capable of interbreeding to make infertile babies

77
Q

Dichotomous key

A

A sequence of paired questions that can be used to identify organisms - designed around visible features

78
Q

Common ancestors of different species can be found through

A

Evolutionary relationships

79
Q

DNA sequencing

A

The sequences of the bases within DNA can identify close sequences between different species - similar base DNA = close relationship. It’s powerful as it doesn’t rely on visual features.

80
Q

No backbone, jointed legs, segmented bodies, exoskeleton

81
Q

Viruses aren’t considered living organisms because

A

They aren’t made up of cells and don’t do the Mrs. Gren stuff
