The salamanders will decrease in number because of the water quality

The salamanders will adapt to life on land

The salamanders will move to another river

Which of these best explains the difference between the way animals and plants exchange gases with their environment?

Animals use only respiration, while plants use both photosynthesis and repiration

Animals use only photosynthesis, while plants use both photosynthesis and respiration

Animals use both photosynthesis and respiration, while plants use only respiration

The species would become extinct

The species would continue to thrive

Polar bears swim across large expanses of ocean while hunting for seals, their main source of food. The bears use sea ice as a resting spots during their long swims. However, the sea ice is rapidly melting as a result of global warming. Which statement describes what most likely happen if global warming continues at its present rate?

Polar bear populations will decrease, and seal populations will increase.

Polar bear and seal populations will both increase

Polar bear populations will increase, and seal populations will decrease.

Polar bear populations will decrease, and seal populations will remain the same

Which of these would lead to a lower rate of photosynthesis in a plant?

a decrease in the amount of carbon dioxide in the air

an increase in the amount of oxygen in the air

a decrease in the amount of oxygen in the air

an increase in the amount of carbon dioxide in the air

What is the result of the fertilization of an egg?

it restores the diploid number of chromosomes

it deletes polypeptide chains in the chromosomes

it gives offspring more chromosomes that the parents

it gives offspring fewer chromosomes than the parents

A species of snake was introduced to a tropical region. Scientists then noticed a steady decline in the presence of a field mice and an increase in the number of snakes. Which of these is the most likely explanation about why the population size of each animal changed?

The mice became prey to the introduced snakes, allowing the snake population to increase but decreasing the mice population

The snakes introduced to the region dominated the habitat, forcing the mice to find another place to live

The snakes introduced to the region competed with the mice for food, allowing the snake population to increase but decreasing the mice population

The people in the surrounding are set traps that killed the mice, allowing the snakes to live without any predators and therefore to increase in number

How would a drop in temperature most likely affect the process of cellular respiration and photosynthesis?

The rate of both would decrease

the rates of both would remain constant

the rate of PS would increase, the rate of CR would decrease

the rate of PS would decrease, the rate of CR would increase
