Because of their function, we would expect muscle cells to have a large number of which cellular organelle?
Mitochondria
100
____________ is the process of taking material into the cell by means of infoldings of the cell membrane.
Is it Endocytosis?
100
Which body system's is used for communicating with the body with electrical messages?
Nervous System

A female cat has two recessive genes for long fur (ss) and a male cat has two dominant genes for short fur (SS). What is the likelihood the two cats produce a kitten with short fur?
Will 100% of the kittens be short fur?
100
Many plants will grow from cuttings. The cutting develops a new root system and becomes a clone of the parent plant, but an independent new plant. This type of reproduction is called?
Do we call this asexual reproduction?
200
Which organelle, found in this plant cell, breaks down sugars for cellular energy?
Mitochondria
200
Definition: The process when molecules tend to move from an area of high concentration to an area of low concentration.
Example: When you put food coloring into water and over time it spreads out evenly.
Diffusion
200
When cells with the same function join together with other cells, they form
Tissues

According to the Punnett square: B represents the dominant gene for blue feathers and b represents the recessive gene for red feathers. Two heterozygous birds have one offspring. What percent chance does it have for red feathers?
Is there a 25% chance that the offspring will have red feathers?
200
Definition: This is a type of reproduction where there is a exchange of genetic information in order to create new individuals.
Example: Higher form or reproduction...done by plants and animals.
Sexual
300
Definition: These are organelles that digest macromolecules.
Lysosome
300
What are the products of photosynthesis?
oxygen and glucose
300
How does the muscular system depend on the nervous system?
The nervous system sends signals to the muscles to cause movement.
300
How do we describe a Rr genotype?
Do we refer to this genotype as heterozygous?
300
The offspring from asexually reproduced organisms are? Different or Identical?
Identical
400
Definition: This is a regulation of the internal environment of an organism.
Example: Temperature regulation in humans.
Homeostasis
400
Definition: The process of nuclear division in cells that produces daughter cells that are genetically identical to each other and to the parent cell.
Mitosis
400
Which system has the following function: transports or carries oxygen and nutrients to cells, takes carbon dioxide away from cells
Circulatory
400
Definition: This is an observable trait of an organism that can mask the recessive trait.
Example: The Capital R in this Punnett Square, or brown eye color in humans.
Dominant
400
It is very common for yellow labs to have bad hips. This is because owners want purebred yellow labs who are good hunting dogs. This is an example of
Selective Breeding
500
Compare and contrast the structures in a plant cell and an animal cell. Point out any differences and similarities.
Both have- nucleus, cell membrane, mitochondria
Plants Only- Have cell wall and chloroplasts
500
The picture shows glucose molecules moving across a cell membrane.
- Describe the process by which glucose molecules pass through the cell membrane. Be sure to state the kind of molecule that allows glucose molecules to pass through.
- Explain whether this is an instance of active transport or passive transport.
A) Diffusion
B) Passive Transport
500
Explains how the muscular system relies on the respiratory system?
The respiratory system brings oxygen into the body for the muscular system to use.
500
Definition: This is a diagram that shows the gene combinations that might result from a genetic cross.
Example: Traits can be determined using this.

The guppy is a species of small freshwater fish. Scientists observed that the average size of guppies in the pond decreased after many years after a guppy predator was introduced into the pond. Which of the following best explains the change in guppy size?
Natural Selection
