Positive
Negative
When you run, you begin to breathe heavier and faster. Your heart beats more quickly, bringing more oxygen to your cells. Which two systems are working together?
Cardiovascular and Respiratory
Excretory and Immune
Digestive and Cardiovascular
Nervous and Respiratory
After you eat a meal, the body breaks down food and gets the nutrients out of them. These nutrients are then carried to different regions of the body via the bloodstream. Which two systems are working together to make this happen?
Cardiovascular and Respiratory
Excretory and Immune
Digestive and Cardiovascular
Nervous and Respiratory
The muscular and digestive systems work together to digest food. The muscles in the mouth help to chew the food, the muscles of the esophagus push the food down to the stomach, and the muscles in the stomach help churn and break down the food. How would the digestive system be affected if humans didn't have a muscular system?
Food wouldn't get pushed down into the stomach and the stomach wouldn't be able to churn the food
It wouldn't be affected because the muscular system doesn't work with the digestive system
The food would still travel the same path as gravity would take over.
The food would just absorb into the body through the mouth.

effector

Monosaccharide
Lipids/Fats
Fatty acid/glycerol
Proteins
Amino Acids

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?
So the proper genetic information is transferred into daughter cells.
So the cell can increase in size.
So DNA stays in the nucleus.
So the cell can re-order the DNA sequencing in the new cells.
In mitosis, the two daughter cells are
different from the parent cell and identical to each other.
different from the parent cell and different from each other.
identical to the parent cell and different from each other.
identical to the parent cell and identical to each other.
Cells go through mitosis to create cells for.....
growth
repair of damaged cells
replacement of dying cells.
All of the above
A human cell has 46 chromosomes before mitotic division. How many chromosomes will the daughter cells contain after mitosis?
12
23
46
92
What kind of cells are made in MEIOSIS?
Haploid Gametes
Diploid Somatic Cells
Skin Cells
Liver Cells
If a somatic (body) cell in a butterfly contains 24 chromosomes, a butterfly egg (gamete) would contain
3
6
12
24
What is one of the advantages of sexual reproduction?
quick
overproduction
genetic variation
cloning
All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -
makes its own food
is unicellular
live in a marine habitat
reproduces asexually

They are exact copies of one chromosome
They were formed during DNA replication
They will split during mitosis

DNA replication is known as "semiconservative" because...
Half of each new DNA strand is conserved from the original strand
It isn't liberal DNA
It doesn't twist into a double helix
It disintegrates during anaphase
Why would DNA need to replicate?
When it gets old
When proteins need to be created
When a chromosome has a mutation from the parent
When a cell is about to divide

Mitosis
As a zygote divides to form new cells, groups of cells specialize to carry out functions that are essential to the organism. What causes cells to differentiate into specialized cells?
activation of specific genes
activation of specific tissues
activation of specific sex cells
activation of specific amino acids
Part "A" in the diagram represents the ___________ that occurs after the creation of the zygote.
meiosis
specialization
mitosis
Bonnie and Clyde have a child. The child looks a lot like Bonnie. Clyde thinks this is because the child has more DNA from Bonnie than from him. Is his claim correct? Why?
Yes, because at cell division, more DNA from mom ended up in the cells.
No, because the cells in the child have half of the DNA from mom and half from dad.
