Q

How does cell multiplying

A

Reproduction

20
Q

What are the two categories of reproducers?

A

Asexual and sexual reproduction

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 reproduction

23
Q

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

A

Sexual reproduction

24
Q

How does offspring develop from asexual reproductions?

A

Asexual reproduction produces offspring that are genetically identical to the parent

25
Q

What are cells?

A

The building blocks of all living things.

26
Q

What are the 3 rules of Cell Theory?

A
  1. All living thing come form one or more cells 2. Cell are basic unit of life 3. All cell’s arise form a pre-exising cells
27
Q

What does autotrophic mean?

A

requiring only carbon dioxide or carbonates as a source of carbon and a simple inorganic nitrogen compound for metabolic synthesis of organic molecules (such as glucose) autotrophic plants — compare heterotrophic.

28
Q

Whats a food chain

A

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

29
Q

Define the characteristic: Obtains energy

A

to gain possession of; acquire; get

30
Q

2 ways different organisms can obtain energy

A

Autotrophism and heterotrophism

31
Q

Plants are heterotrophic. True or False

A

False

32
Q

What type of organisms are heterotrophic?

A

organisms who cannot produce their own food are called as heterotrophs.

33
Q

Define biotic

A

relating to or resulting from living things, especially in their ecological relations.

34
Q

Define abiotic

A

physical rather than biological; not derived from living organisms.

35
Q

What is growth/ developments

A

The increase of size and mass of an organism.

36
Q

Define development

A

involves transformation of an organism as it goes through the growth process.

37
Q

what is sensitivity?

A

The ability for any organism to respond to internal or external stimulus.

38
Q

What does Homeostasis

A

The internal balance of an organism.

39
Q

Define adaptations

A

the action or process of adapting or being adapted.

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

the act of sweating to cool the body down is a response

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

Low blood sugar causes people to feel irritable, confused and fatigued.

42
Q

What are membrane-bound organelles?

A

Membrane-bound organelles are cellular structures that are bound by a biological membrane. The membrane may be a single layer or a double layer of lipids and typically with interspersed proteins.

43
Q

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

A

Prokaryotic

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 the objective being used in 40x?

A
