Should you eat a random mushroom that you find while you wander a forest?
NO!!!
What are the two steps of photosynthesis?
1. Light reactions (solar energy into chemical energy)
2. Calvin cycle or light independent reaction (chemical energy used to reduce carbon dioxide to carbohydrates)
What are the four nucleotide bases of DNA and how do they pair up with each other?
Adenine, Guanine, Thymine, Cytosine.
Pairing:
A-T and G-C
What is the difference between microevolution and macroevolution?
Microevolution is changes in allele frequency and happens pretty constantly in nature. Macroevolution is on a larger scale, an example is co evolution.

Cuticle that protects from water loss, stomata allow for gas exchange, vascular system for support (stem), roots to anchor into ground
Explain a type three survivorship curve and an example of an organism that has this.
The death rate for the population peaks early in life but then settles out.
Example: marine animals that release eggs into water, plants that release huge numbers of tiny seeds.
What are the three categories of plants?
Nonvascular plants/bryophytes, Vascular seedless plants, and Vascular seed plants
