Q

The process of which organisms give birth to offspring.

A

Reproduction

20
Q

What are the two categories of reproducers?

A

Sexual and asexual reproducers.

21
Q

Which type of reproducer is made up of only one parent?

A

Asexual reproducers.

22
Q

Offspring from which type of reproducer develops from the
combination of receiving 50% chromosomes from a female
parent and 50% chromosomes from a male parent?

A

Sexual reproducers.

23
Q

Which type of reproduction requires 2 parents from each
gender (1 male, 1 female) to create offspring?

A

Sexual reproducers.

24
Q

How does offspring develop from asexual reproductions?

A

The offspring’s DNA has to be identical to the parent’s.

25
Q

What are cells?

A

The building blocks of all living things.

26
Q

What are the 3 rules of Cell Theory?

A

All living things are made up of one or more cells. All cells come from other cells. Cells are the most basic building blocks of life.

27
Q

What does autotrophic mean?

A

it means the organism makes it’s own food from sunlight.

28
Q

What does hetrotrope mean?

A

Any organism that consumes other
organisms for food in order to create
energy for the body.

A

How living things adapt to and survive in their enviroment.

40
Q

The classroom thermostat is broken and the room is very hot
and stuffy. How will your body internally respond to this external stimulus?

A

Your body starts to get sweaty and your nervous system sends signals to your brain telling you it’s hot.

41
Q

Your day has been busy and you forgot to have breakfast
and then missed lunch. How will your body internally alert
you that it requires nourishment (food)?

A

Your stomach starts to make some strange noises and telling your brain you’re hungry and need to eat.

42
Q

What are membrane-bound organelles?

A

Cellular structures in an organism bounded by a biological membrane.

43
Q

Which category of cells does not contain membrane-bound
organelles?

A

Prokaryotic cells.

44
Q

All categories of cells contain DNA. True or False

A

true

45

multicellular organisms?

A

Eukaryotic cells.

46
Q

What is the formula for total magnification when looking
through a microscope?

A

Multiply the power of the ocular lens by
the power of the objective being used.

47
Q

What is the total magnification if the ocular lens is 10x and
the objective being used in 40x?

A

400x
