Pea

Question 2

What is a description of the alleles present in an individual?

Answer 2

Genotype

Question 3

What is a tool that would help predict patterns of heredity?

Answer 3

Punnett Square

Question 4

What is Phenotype?

Answer 4

Observable traits of an organism. P H E N O T Y P E (P for Physical) (N for Noticeable).

Question 5

If a gene was homozygous recessive, how would you represent it?

Answer 5

Two lowercase letters ( ex. hh ).

Question 6

How many copies of alleles does each person have?

Answer 6

2

Question 7

If a gene was heterozygous, how would you represent it?

Answer 7

You would represent it by using an uppercase and a lowercase letters. (Hh)

Question 8

What is carrying capacity?

Answer 8

Size of population that is supported by resources in a given location

Question 9

What usually happens to a population of organisms when the region’s carrying capacity has been reached?

Answer 9

it levels off

Question 10

What is an ecosystem?

Answer 10

All the living and nonliving things in an area.

Question 11

What are populations influenced by?

Answer 11

Resources like prey, food, water, sunlight, predators, and shelter.

Question 12

Explain the relationship between population and community and ecosystem.

Answer 12

Population is a group of the same species in the same area. A community is all the populations of different species living in an area. An ecosystem is all the living and nonliving things in a given area

Question 13

What happens when the needs of species are no longer met?

Answer 13

They migrate or die off and eventually become extinct

Question 14

What are some causes of extinction?

Answer 14

Habitat loss and not enough resources (lack of water, food, and shelter)

Question 15

When does overpopulation of species occur?

Answer 15

If their species number exceeds the carrying capacity.

Question 16

Why is overpopulation so dangerous?

Answer 16

It overtakes the ecosystem and it messes up the food web.

Question 17

What is the most common effect of overpopulation?

Answer 17

Starvation

Question 18

What happens if an ecosystem is left alone?

Answer 18

A balance will eventually return.

Question 19

What happens when population numbers increase?

Answer 19

Resources are used up faster.

Question 20

What molecule is most responsible for the adverse effects of pollution and deforestation on Earth’s climate?

Answer 20

Carbon dioxide

Question 21

What is global warming?

Answer 21

The slow warming of earth’s atmosphere due to the warming of the Earth

Question 22

What does anthropogenic mean?

Answer 22

Caused by humans

Question 23

What are the greenhouse gasses?

Answer 23

Greenhouse gasses are the gasses that are on the outside of the earth that trap the Earth’s sunlight.

Question 24

What is happening to the weather that is a sign of climate change?

Answer 24

Extreme storms and glaciers are melting.

Question 25

What is a water cycle?

Answer 25

The water cycle is the movement of water among various reservoirs.

Question 26

What is the most important source of energy that drives the water cycle?

Answer 26

The sun

Question 27

What are the basic forces that drive the water cycle?

Answer 27

Gravity and buoyancy

Question 28

What does the global wind system and the resulting currents in Earth’s oceans move around the planet?

Answer 28

Thermal energy and moisture around the planet.

Question 29

What is precipitation?

Answer 29

Precipitation is a part of the water cycle. There are many types of precipitation (rain, snow, sleet, and hail)

Question 30

What are temperatures affected by?

Answer 30

They are affected by seasons and the water cycle

Question 31

What is a meteorologist?

Answer 31

Person who studies weather

Question 32

Name some of the tools meteorologist use.

Answer 32

Thermometers, barometers, anemometers, rain gauges, hygrometer, psychrometer, ceilometer, radar, disdrometer, wind profiler, and imagers (cameras).

Question 33

What is a front?

Answer 33

A front is boundary between large masses of air with different densities.
