Unit 0 Biothemes/Characteristics of life

Question 1

Interdependence

Answer 1

organisms depend on each other

Question 2

levels of organization

Answer 2

1. organisms
2. populations (A group of individuals of the same species living in the same area)
3. communities (different populations living in an area)
4. ecosystems All biotic and abiotic factors
5. biosphere

Question 3

form determines functions

Answer 3

the shape, structure or design of a biological entity (form) it directly linked to its role or function; Bird Wings: The aerodynamic shape of wings facilitates flight; RBC biconcave shape allows for gas exchange

Question 4

flow of matter and energy

Answer 4

most of the energy starts in the sun and flows in one direction; however matter flows in cycle (water i.e)

Question 5

homeostasis

Answer 5

the ability for the body and organisms to adapt to their external environment; i.e sweating, increased heart rate

Question 6

continuity and change

Answer 6

everything is related because they have DNA but its slightly different because of mutations and that gives variation

Question 7

unity within diversity

Answer 7

all life forms are fundamentally connected through shared biological principles, even as they exhibit a wide range of adaptations to different environments.

Question 8

evolution by means of natural selection

Answer 8

the genes that are stronger and contribute a benefit to the organism will have a higher chance of being passed down in their offspring

Question 9

Living things are based on a universal genetic code.

Answer 9

all organisms have DNA; that is their code

Question 10

Living things grow and develop.

Answer 10

all living things increase in size and/or over their lifespan

Question 11

Living things respond to their environment.

Answer 11

they respond to their external environment to maintain homeostasis

Question 12

Living things reproduce.

Answer 12

they create new organisms similar to themselves, ensuring the continuation of their species;

Question 13

Living things maintain a stable internal environment.

Answer 13

all living things are able to maintain their internal environment is called homeostasis

Question 14

Living things obtain and use energy.

Answer 14

they can obtain energy through food or the sun to power their bodily and cellular processes

Question 15

Living things are made up of cells.

Answer 15

cells are the most basic unit of life; cells to tissue to organs to organ systems to organism

Question 16

Taken as a group, living things evolve.

Answer 16

a group of organisms with shared characteristics change over time through natural selection, leading to evolution.
