Genetics
G= Green g=Yellow. The genotype for a yellow plant would be...
A. Gg
B. gg
C. GG
D. gG
B! Lowercase letters mean recessive! So Yellow has to be gg, because if it was Gg, it would be green!
Are Viruses living? (You get double the points if you can tell me why)
No they aren't, they cannot reproduce on their own.
Where does photosynthesis take place?
A. Water vacuoles
B. Chloroplasts
C. Mitochondria
D. Ribosomes
B!
What does the Digestive system do?
Breaks down food and absorbs nutrients
An animal that only eats meat is known as a...
Carnivore!
What is it called when you have two different genes?
A. Heterozygous
B. Homozygous
C. Mendelian Inheritance
D. Phenotype
A! Heterozygous means different, homozygous means the same! Heterozygous genes would be Aa, while homozygous genes would be AA or aa.
Which can be treated with antibiotics?
A. Virus
B. Bacteria
C. Pathogen
D. Disease
B!
What is the function of a cell wall?
To protect and support the cell
What does the respiratory system do?
What does every food chain start with?
The sun
What is the physical look of a trait called?
A. Phenotype
B. Genotype
C. Allele
D. Recessive
A. Phenotype is the physical look of a trait. For example a frog's phenotype would be green!
What is a host?
A cell that a virus invades!
Cells with a nucleus and membrane-bound organelles are called..
A. Prokaryotic
B. Eukaryotic
C. Bacteria Cells
D. Protists
B!
What does the excretory system do?
Excretes waste.
An illustration that uses arrows to show the MANY possible directions in which matter and energy can pass through the organisms in an ecosystem.
A food web
If one parent has A type blood, and the other parent has B type blood, what are the possible blood types for the child?
A. A, AB, B
B. A, O
C. A, AB, B
D. A, B, AB, O
D! Parent 1's genotype for blood is Ai, because I blood is recessive. Parent 2's genotype is Bi, so if you cross them, all the genotypes you would get would be AB, Ai, II, and Bi. Well because I is recessive, Ai and Bi would be A type and B type blood. And 2 i's results in type O blood. So the child can have every blood 25% chance on each.
Where do Viruses reproduce?
Inside the cell! They reproduce in the cell and replicate so much until the cell bursts and the virus is spread all over!
What is the basic function of a vacuole?
To store water! Water vacuoles are in plant cells, and they are used to store water and sometimes waste!
Name 5 body systems.
Endocrine, Integumentary, Reproductive, Circulatory, Muscular, Skeletal, Lymphatic, Respiratory, Digestive, Excretory, Cardiovascular, Urinary, Nervous
There are many symbiotic relationships between animals in their ecosystems. What is the relationship between a flea and a dog?
Parasitism! Parasitism is where one organism is harmed and one is helped. Two other symbiotic relationships would be Mutulaism and Commensalism. Mutualism is where both organisms are benefitted. An example of this would be oxpeckers and zebras. Oxpeckers eat ticks off of zebras, they get food, and zebras get ticks off of them. Commensalism is where on organism is helped and the other is unharmed. For example, Remora Fish attach to the bellies of sharks and many other bigger fish for protection, but the other organism is unharmed.
If the mom's genotype is Aa and the father's genotype is AA, what percent of their children would have the genotype Aa?
A. 50%
B. 25%
C. 75%
D. 100%
What do viruses have in common with cells?
A. They both are living
B. They both have a surface marker
C. They both store Genetic information
D. They both make proteins
C!
What scientist was the first person to see a cell under a microscope and name it?
A. Theordor Schwann
B. Robert Hooke
C. Mattias Schlieden
D. Anton Van Leewenhook
B! Schwann was first to determine that cells make up animals, Schlieden was first to determine that cells make up plants, and Leewenhook was is known as the father of microbiology!

Muscular- To run
Excretory- Excreting sweat while running
Skeletal- To hold body together while running
Circulatory- Circulating blood so she can function
Respiratory- Allows her to breath
Nervous- Allows her to move
Cardiovascular- She is worked up and her heart is pumping much blood
What percentage of energy is transferred to the next level of a tropic pyramid?
10%
