In question 1 what would happen if the arctic hare did not have these specific traits?

Young hares surviving to adulthood would be diminished

Which of the following characteristics best describe the animal kingdom?

heterotrophic, eukaryotic, multicellular

the picture shows runoff. A likely cause of the runoff is:

pavement/concrete prevents water from entering groundwater

If arctic temperatures increase, what is the long-term outlook for polar bears?

polar bear population will gradually decrease

This describes a key interaction between what two body systems?

circulatory and respiratory systems

Cell theory does not include the idea that:

all cells in all organisms of same species carry exact genes

In the graph below, what is a possible reason why the population of gray peppered moths changed

Human pollution changed the moths' natural habitat

What statement best completes the chart below?

Variation of genes makes them less susceptible to disease

Answers

1
In question 1 what would happen if the arctic hare did not have these specific traits?
The hare would be a popular target for game hunters
Young hares surviving to adulthood would be diminished
All of the above
The species would become overpopulated
2
Which of the following characteristics best describe the animal kingdom?
heterotrophic, prokaryotic, multicellular
heterotrophic, eukaryotic, multicellular
autotrophic, eukaryotic, multicellular
heterotrophic, prokaryotic, unicellular
3
The hare is camouflaged in snow. When summer arrives, what traits are needed to avoid predator
thickness of its fur
ability to eat lots of grass
small size in comparison with predators
long ears and fast hind legs
4
the picture shows runoff. A likely cause of the runoff is:
sediments being deposited in steams/rivers around urbanareas
larger amounts of farmland to support more people
pavement/concrete prevents water from entering groundwater
increased rainfall in urban areas
5
Jessie catches a fish with the following characteristics. This fish is most likely a:
rainbow trout
bluegill
largemouth bass
catfish
6
If arctic temperatures increase, what is the long-term outlook for polar bears?
polar bear population will gradually decrease
polar bears will adapt quickly to new food sources
polar bear population will remain unchanged
polar bear population will gradually increase
7
This describes a key interaction between what two body systems?
endocrine and skeletal systems
circulatory and respiratory systems
digestive and circulatory systems
nervous and respiratory systems
8
Cell theory does not include the idea that:
cells use energy from food to sustain life
all cells in all organisms of same species carry exact genes
all living things are made of cells
like cells carry similar functions
9
In the graph below, what is a possible reason why the population of gray peppered moths changed
Human pollution changed the moths' natural habitat
The moths were unable to reproduce
The moths' food source vanished
The number of predators increased
10
Which arrow is pointed to the organelle that contains the genetic material for inherited traits
Structure C
Structure A
Structure E
Structure B
11
What statement best completes the chart below?
allows for rapid reproduction in large numbers
provides the ecosystem with more consistency
genetic traits are likely to be an exact match of offspring
Variation of genes makes them less susceptible to disease
