Cell Organelles
What are cells?
Cells are the basic units of life.
What is Photosynthesis?
Photosynthesis is the process where autotrophs (an organism that has the ability to make its own food) convert light energy into chemical energy, using sunlight.
What is DNA?
DNA is a Nucleic Acid.
The monomer of a nucleic acid is a nucleotide.
The function is to provide instructions for making proteins.
What is competition?
Competition is the struggle between organisms for limited resources in their environment. Can be between the same species or different species
What is Deforestation?
What is the cause and effect?
Cause; Human are removing trees to make room for new homes, using it for lumber, clear cutting for agriculture, and expanding businesses/roads.
Effect; Loss of habitat for animals (decreases biodiversity) and this upsets the carbon cycle. No photosynthesis to remove excess carbon. Also, increases erosion (loss of soil).
What living things carry Eukaryotic Cells?
All animals, plants, and fungi.
Where does Cellular Respiration take place?
It starts in the cytoplasm and moves to the Mitochondria if Oxygen is present.
Complementaty Base Pairing;
What pairs up with the letter,
A -?
C-?
T-?
G-?
Correct answers are,
A-T
C-G
T-A
G-C
Territoriality is defending physical space against other animals.
- Reduces competition for scarce resources (Land, mates).
What is the Carbon Cycle?
Write down before looking at the answer?
The Carbon Cycle tracks the progress of carbon in molecules from gas to solid and back again.
Humans change the balance of the Carbon cycle by burning fossil fuels.
What does the Mitochondria create for the cell?
The Mitochondria creates ATP for the cell
What is the Photosynthesis formula?
(Write it down before checking answer).
6CO2+6H2O-C6H12O6+602
Reactants: Carbon Dioxide, Water, & Sunlight
Products: Glucose & Oxygen
What is RNA made of?
RNA is made of ribose sugar.
What are Symbiotic Relationships?
Symbiosis: a relationship between two organisms that live close together in which one or both benefit.
What is the Nitrogen Cycle?
Write down before looking at the answer?
Decomposition; Decomposers such as bacteria and fungi break down dead organisms and return nitrogen to the soil.
What does a Sperm Cell spealize in?
The process by which Cells make ATP (energy) by breaking down organic compounds (food).
Translate the following code; (write down before moving on)
1. A T G C A G G C A T
2. G C T T A A G T C A G C
The correct answers are;
1. T A C G T C C G T A
2. C G A A T T C A G T C G
Animal Behavior-Insight Learning
What is Insight Learning?
Insight Learning;
applying pre-known knowledge to a new situation.
Most complex!
Non-Renewable and Renewable Resources.
Renewable Resources: Are replenished naturally and over relatively short periods of time.
Nonrenewable Energy Resources: Are avaliable in limited supplies. This is usually due to the long time it takes for them to replenished.
What does a Nerve Cell specialize in?
It conducts electrical impulses for communication.
What is the equation for Cellular Respiration?
(Write it down before checking).
6O2+C6H12O6--6CO2+36ATP
Reactants: Glucose and Oxygen
Products:Carbon Dioxide (waste),
Water and ATP (energy)
What Is A Mutation?
A mutation is a permanent change in an organism DNA sequence.
Example these three on a piece of paper:
Mutualism;
Parasitism;
Commensalism;
Answers;
Mutualism; both organisms benefit. Ex; The bee gets pollen and flower gets pollinated
Parasitism; one organism benefits and one is harmed, Ex; The flea takes away the mammal's blood ( and passes on disease, is itchy, etc..)
Commensalism; one benefits and the other is unaffected. Ex; The barnacle gets moved around, but isn't taking nutrients from or harming the whale.
What is Biomagnification?
What are the causes and effects?
Cause; Some substances build up in organsims
bodies instead of passing out, so they're found in increasing amounts higher on the food chain. DDT is a pesticide that does that.
Effect; Decreased the population of high trophic level birds (ex; eagles). It caused their eggs to be weak and they broke when sat on.
