What is development (or metamorphosis)?
100
These types of cells do not have a nucleus or organelles

How does the DNA in all of your body cells compare?
It's all the same
100
This type of feedback is more common because it returns an organism to homeostasis.
negative feedback

A microscope has a 10× ocular lens and a 40× objective. What's the total magnification
400x
200
Living things maintain a stable internal environment. What is this called?
(Homeostasis)
200
These types of cells are large, complex and contain organelles
eukaryotic cells
200
What is the function of the mitochondria
Generates energy (ATP)
200
What type of cell is this?
Plant cell

Homeostasis is one of the fundamental __________ of life because all living things seek it.
characteristics
200
means a plant bending toward light is showing this characteristic of life
What is responding to a stimulus?
300
The sum of all chemical reactions in an organism
metabolism
300
Found in plant cells but not animal cells, these provide structure and are made of cellulose.
whati s a cell wall?
300
Chloroplast
300
What type of cell is this?
Animal Cell

When we exercise, our muscles produce CO2 as a waste product, causing our blood to become more acidic. Sensors detect this acidity and signal our lungs to breathe more. This helps to release more CO2 and make our blood less acidic.
What type of feedback is this and why?
It's negative feedback because it is returning our bodies to homeostasis in terms of our desired CO2 levels and blood acidity levels.

This organelle is the "control center" and contains DNA.
What is the nucleus?
400
This organelle controls what enters and leaves the cell
cell membrane
400
Cells without a nucleus or membrane-bound organelles belong to this group.
what is a prokaryote?

Sweating and shivering are both examples of the body regulating this variable
what is body temp?
400
What is the name of the special type of unspecialized cell that can create specialized cells?
stem cells

his mysterious cave specimen is ruled "alive" because it absorbs sulfur for energy, recoils when poked, and splits into new, growing organisms—demonstrating metabolism, response to stimuli, and this final core characteristic of life.....
What is homeostasis?
500
List three structures that are found in both prokaryotic and eukaryotic cells.
DNA, cell membrane, ribosomes, cytoplasm
500
Protein making factory
What are ribosomes?
500
Name all three parts of the cell theory.
(1) All living things are made of cells; (2) cells are the basic unit of structure and function; (3) cells come only from pre-existing cells.

What is insulin?

A cell in salt water shrivels as water exits — water moving across the membrane to balance concentration is an example of maintaining this.
What is homeostasis (
osmotic balance)?
