Humans, as well as all other multicellular, heterotrophic organisms that lack cell walls, belong to this kingdom.
Animalia (Animals)
100
Animals of the same species will work together in packs or herds for protection and to get resources. This is an example of which form of animal interaction?
(Competition, Cooperation, or Symbiosis)
Cooperation
200
What is DNA used to make?
Proteins
200
What is the process by which traits that allow an organism to survive and reproduce are more likely to be passed on to offspring. (Also known as "survival of the fittest")
Natural Selection

Which organelle in plant cells performs photosynthesis?
EXTRA POINTS: What does photosynthesis do?
Chloroplast
Photosynthesis uses energy for the sun (plus carbon dioxide and water) to make food (glucose) and well as oxygen.
200
This kingdom includes multicellular organisms that make their own food through photosynthesis and have a cellulose cell wall.
Plantae (Plants)
200
Wolves and bears both hunt for similar prey in the same area. This is an example of which form of animal interaction?
(Competition, Cooperation, or Symbiosis)
Competition

What are the three main parts of a DNA molecule that form the “rungs” and the “backbone” of the ladder?
Rungs: Nitrogenous bases
Backbone: Sugar and phosphate

(Bacteria, Eukarya, or Archaea?)
EXTRA POINTS: How are prokaryotes different form eukaryotes?

300
Bees get nectar (food), while flowers get pollinated, allowing them to reproduce.
Which form of symbiosis is this? Mutualism, Commensalism, or Parasitism?

If brown eyes (B) are dominant over blue eyes (b), what is the genotype of a person with blue eyes?
(EXTRA POINTS : If a pea plant has one allele for tall (T) and one allele for short (t), and tall is dominant, what is the plant's genotype and what height will it show? )
bb (homozygous recessive)
EXTRA: Tt (heterozygous) and tall
400
These are preserved remains, found in different rock layers, permafrost, and hardened tree sap, that provide a timeline of how species have changed over millions of years.

Parasitism
500

Extra: What is the probability that the offspring will get the recessive trait?
RR (homozygous dominant) and Rr (heterozygous)
EXTRA: 0%
