The part of an experiment that does not change in each setup

The Control

In an experiment, the effect of the variable changed by the scientist; measured as “the results”

The dependent variable

In an experiment, the variable directly changed by the scientist

The independent variable

A graph for recording data from the following experiment: Problem question: What is the effect of fast-paced music on the rate of one’s pulse ? ?

Pulse Rate Pace of Music

The function of the control in a scientific experiment

The basis of comparison; by comparing results with the setup containing the variable, we see the effects of the variable

The removal of metabolic wastes from an organism

Excretion

Occurs by adding more cells or increasing their size

Growth

Respiration inside cells does this

releases energy from food

Needed for maintaining homeostasis

Regulation

Three life processes performed by the cell membrane

Transport Excretion Regulation

Regulation of the cell’s activities originates here Daily Double! Regulation of the cell’s activities originates here

The nucleus

This structure

Cell membrane

Three things found in plant cells but not in animal cells

Chloroplasts Cell Wall Large water vacuole

How are viruses similar to cells? How are they different?

Similarities same molecules (DNA, RNA, proteins) can reproduce Differences Slide 3 cannot reproduce without a host cell do not perform all the life processes

prokaryotic and eukaryotic cells 3 similarities and 3 differences between prokaryotic and eukaryotic cells

Similarities Cell membrane and cytoplasm Same molecules Same life processes Differences Slide 3 one has nucleus one doesn’t one has internal membranes the other doesn’t size

Where proteins are made

ribosomes

site of photosynthesis

chloroplasts

plant cells have a box-like shape because it’s stiff

the cell wall

Only found in animal cells; Used in cell division

centrioles

Which 2 structures are present in every cell on Earth? 1 2 3 4 5

2 structures present in every cell 5 – endoplasmic reticulum 1 – cell membrane 2 - cytoplasm 3 - nucleus 4 - mitochondria 5 – endoplasmic reticulum

Direction to move the slide to get X in the center Daily Double! Direction to move the slide to get X in the center X

Up and to the left

The diaphragm controls this

The amount of light entering the microscope

Daily Double! This happens to the amount of area and the amount of detail when you switch from low to high power

less area and more detail

The length of the organism in the field of view High power diameter = 400 um

300 um

The microscope used to take this picture; Is this creature living, non-living, or dead? Why?

The electron microscope Dead; Dehydration
