TCI Cells & Genetics Unit 1 Study Guide A

Why would a plant produce a chemical that tastes bitter to certain organisms?

To prevent predation

What are the requirements that must be met for an engineering solution to be successful?

Criteria (Singular: criterion)

What are the limitations on an engineering solution?

Constraints

What is a distinct feature or body part of an organism?

Physical trait

What is a relationship between two living things where one organism captures and feeds on the other ?

Predation

What is to suffer or die from lack of food?

Starvation

What is an abnormal and excessive loss of water from the body of an organism?

Dehydration

What is to suffer or die from lack of oxygen?

Suffocation

What is a group of living things that share traits and can successfully breed with each other but not with other groups?

Species

What is the process by which an organism makes more organisms of the same species?

Reproduction

What is a way of acting that will help an animal attract a mate?

Courtship behavior

What is a representation of something in the real world which makes important aspects easier to observe and hides unimportant aspects?

Model

What is to begin the growth of a new plant from a seed?

Germinate

All organisms acquire their needs for energy, materials, and living space from...

Their environment

Which of the following statements is NOT true of an organism's relationship with food?

Animals do not get food from their environments.

Which of these is likely to cause dehydration in an organism?

A drought that lasts for five years

Which of these is true of a plant's needs for survival?

Plants do not have to eat food because they make their own.

The survival of organisms can be threatened by...

Extreme temperatures, the risk of diseases, the danger of being eaten by others

One example of a physical trait is the...

Quills on a porcupine

How does a woodpecker's beak help to protect it from starvation?

It is long and narrow making it easy to get insects out of holes.

Criteria and constraints are chosen based on...

Human need, societal values, available resources

Why is a bear with thick fur more likely to produce offspring than a bear with thin fur?

Bears with thick fur are more likely to survive cold winters and live long enough to reproduce.

Which of these is true of an animal's reproductive traits?

Reproductive traits increase the chance that an animal will find a mate.

Which of these is an example of an animal's physical trait for reproduction?

Kangaroo's pouch

How are a peacock's feathers a physical trait for reproduction?

A peacock uses its feathers to attract a female mate

Why would a mother sea turtle lay 1,000 eggs instead of 10 eggs?

The more eggs she lays, the more likely it is that her offspring will survive.

Which of these is NOT true of the chances of offspring survival for a species that lay many eggs?

All offspring are likely to survive because they are cared for in greater numbers.

Which of these is a benefit of taking care of offspring?

Taking care of offspring means the odds of each offspring's survival is greater.

Which of these is one of the criteria scientists water to meet for condor recovery?

Scientists wanted to create a self-sustaining wild population of condors.

How did scientists overcome the constraint of how often condors lay eggs?

Scientists removed an egg before it hatched causing the condor to lay another.

What was the purpose of the zoo habitat built by scientists for the condors?

The zoo habitat was designed to teach condors to avoid dangers in their natural habitat.

What is one improvement scientists made to the model condor habitat?

Scientists modeled condor mothers by using puppets to feed and take care of baby condors.

What is growing toward the light in plants an example of and what will it help the plant to do?

Behavioral trait and it will help it survive and prevent starvation

What would fertilizer affect in a plant?

It would affect the plant's physical traits

What is an example of a way that plants prevent dehydration?

Thick leaves, roots and stems that store water

What is a distinct way in which an organism interacts with its environment?

Behavioral trait

How do offspring get their physical traits and behavioral traits?

From their parents

What do sounds an organism creates to attract a mate help with?

Attract a mate and reproduce

One environmental factor that affects the growth of a plant is the

hours of daylight a plant receives.
