In which TWO ways could pesticides have contributed to the extinction of a golden toad?

Pesticides may have been absorbed through their skin., They may have eaten insects that contained pesticides.

Natural selection means

individuals that fit best in an environment survive to pass on their genes

Why have rainforest plants adapted to be a different shape and size than desert plants?

because rainforest plants have adaptations that are different from desert's

What is the MOST LIKELY cause for the golden toads' extinction?

They were unable to adapt to the rapidly changing environment.

Considering "adaptation", what would most likely happen if herbivores, like cows, began eating meat instead of grass?

Over the years, cows would develop canine teeth and large molars.

One of these is NOT a reason why species get extinct

If member get enough resources and thrive more than others.

What does Biodiversity mean?

the variety of life in the world or in a particular habitat or ecosystem

How can an environmental change cause a shift in the traits of a population?

An environmental change can make some organisms better suited for survival

Select TWO processes that are MOST LIKELY to cause the variation in bird beak size traits within a population?

Sexual reproduction and Mutation

The golden toad ate insects. How would the extinction of the golden toads MOST LIKELY affect the population of insects?

The population of insect species increased.

What is the main way that being camouflaged helps an animal?

It helps them blend into their environment against other animals.

Why have lions adapted to have sharper teeth than cows?

Lions need to tear into meat, but cows eat grass.

is a random change in a cell's DNA.

Which of the following is true about plants?

Some plants can “feel” and respond to things in the world.

Which of the following is an example of adaptation?

polar bears’ fur turning white over many years

Answers

1
In which TWO ways could pesticides have contributed to the extinction of a golden toad?
The temperature may have increased due to the pesticides.
Pesticides may have been absorbed through their skin.
They may have eaten insects that contained pesticides.
Pesticides could have increased their reproduction rate.
2
Natural selection means
Scientists can changes the genes of an animal with genetic engineering
individuals that fit best in an environment survive to pass on their genes
Parents can select which traits they pass to their offspring
Mutations in DNA do not happen in nature
3
When an organism is removed from existence, it is said to be
Evolution
Extinct
Adaptation
Camouflage
4
Why have rainforest plants adapted to be a different shape and size than desert plants?
because rainforest plants are only raised in zoos
because rainforest plants have adaptations that are different from desert's
because in a rainforest environment, adaptation can happen overnight
because rainforest and desert plants need to store same amount of water
5
What is the MOST LIKELY cause for the golden toads' extinction?
They were unable to adapt to the rapidly changing environment.
Their food supply was greatly reduced before extinction.
They were unable to compete with other organisms for food.
The habitat was unable to support their very high reproduction rates.
6
The process by which forms of life that are better adapted to a specific environment survive and reproduce more is
Mutation
Theory
Natural Selection
Fossil
7
Considering "adaptation", what would most likely happen if herbivores, like cows, began eating meat instead of grass?
Cows would become better suited to survive in their current environments.
Humans would have to stop eating cows and start eating wolves.
Over the years, wolves would start eating only plants, no meat.
Over the years, cows would develop canine teeth and large molars.
8
Evolution explains how Earth's present-day species developed from earlier species through.............
genetic engineering.
natural selection
mass extinctions.
asexual reproduction.
9
One of these is NOT a reason why species get extinct
If members' environmental conditions are not suitable for their survival.
If member get enough resources and thrive more than others.
If members cannot adjust, the opportunity for species' evolution is lost.
They can no longer survive and reproduce in their altered environment.
10
What does Biodiversity mean?
Natural Selection
the variety of life in the world or in a particular habitat or ecosystem
the beautification of organisms in the world around us
the extinction of organisms in the world or in a habitat or ecosystem
11
How can an environmental change cause a shift in the traits of a population?
An environmental change can cause some organisms to change their behaviors
An environmental change can make less suited organisms reproduce fast
An environmental change can make some organisms better suited for survival
An environmental change can cause organisms to choose favorable traits
12
Select TWO processes that are MOST LIKELY to cause the variation in bird beak size traits within a population?
Hibernation and Sexual reproduction
Sexual reproduction and Mutation
Mutation and Hibernation
Asexual reproduction and Hibernation
13
A sudden change in the genes of an organism. It can cause abnormal physical traits.
Fossil
Natural Selection
Mutation
Theory
14
The best synonym for Natural Selection is
Recombination
Environmental hesitation
Cycling of matter
Survival of the fittest
15
An idea that explains something, but may or may not be right.
Natural Selection
Theory
Fossil
Mutation
16
The golden toad ate insects. How would the extinction of the golden toads MOST LIKELY affect the population of insects?
The population of insect species stayed the same
The population of insect species decreased
The population of insect species increased.
The population of insect species also became extinct.
17
What is the main way that being camouflaged helps an animal?
It makes them look dangerous to other animals.
It helps them store more food and water.
It helps keeps them cool in a hot climate.
It helps them blend into their environment against other animals.
18
Why have lions adapted to have sharper teeth than cows?
Lions need to blend in with their surroundings, but cows don't.
Lions are herbivores, but cows are carnivores.
Lions need to crush bones, but cows eat meat.
Lions need to tear into meat, but cows eat grass.
19
Severe or sudden changes in Earth's atmosphere can cause entire species of animals to die. This is called . .
mutation
extinction
revision.
natural selection
20
The remains or traces of plant or animal that lived in another geologic age and have been preserved in earth or rock is
Theory
Mutation
Fossil
Natural Selection
21
True or False: Plants don't have brains, but they still adapt to their environments.
True

22
In biology, changes that happen over time in the gene pool of a population.
Adaptation
Evolution
Extinct
Camouflage
23
A change over time in a organism that makes it better fit for its environment and better able to survive.
Camouflage
Evolution
Adaptation
Extinct
24
A mutation
is a person or an animal randomly selected from the population.
is produced by mating two different species.
is a random change in a cell's DNA.

Venus flytraps are the only plants to have brains.
All plants have the same nervous systems as humans.
Some plants can “feel” and respond to things in the world.
Plants always shake and move after their leaves are touched.
26
Why do plants and animals adapt to their environment?
to become better at getting food
all of the above
to protect themselves against other animals
to become better able to survive in their surroundings
27
Which of the following is an example of adaptation?
