Reproduction

20
Q

What are the two categories of reproducers?

A

Asexual & Sexual

21
Q

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

A

Asexual

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

23
Q

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

A

Sexual

24
Q

How do offspring develop from asexual reproductions?

A

genetically identical to the parent because the offspring are all clones of the original parent

25
Q

Cells

A

The building blocks of all living things.

26
Q

What are the 3 rules of Cell Theory?

A

All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.

27
Q

What does autotrophic mean?

A

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals

28
Q
A

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

29
Q

Q

2 ways different organisms can obtain energy

A

Autotrophism and heterotrophism

31
Q

Plants are heterotrophic. True or False

A

external stimulus?

A
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
42
Q

What are membrane-bound organelles?

A

ellular structures that are bound by a biological membrane

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
Q

Which category of cells can create unicellular and
multicellular organisms?

A

Eukaryotic organisms

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
