Carrier

(Photosynthesis/Cellular Respiration) is an example of fixation. Why?
Photosynthesis - taking an "unusale" carbon form (CO2) and turning it into a "usable" one (Glucose).

Water molecules have a positively charged region and a negatively charged region. What term is used to describe molecules with charged regions?
Polar (molecules)

In (human) Meiosis, the parent cell is (haploid/diploid) and the daughter cells are (haploid/diploid).
Parents are diploid (2N); make haploid (N) daugther cells through meiosis so that they come together to form another 2N.

A flower having both "Red" and "White" alleles produced pink petals. What genetics term would be used to describe these alleles?
Incomplete dominance
(think of each one not being "fully" there)

Describe the difference between Lamarck’s and Darwin’s theories of evolution?
Lamarck - Acquire a beneficial trait (improvement) during one's life and passing it on to their offspring, progressing towards perfection.
Darwin - Individuals who pocess beneficial traits live to survive and reproduce more than others, so those traits become more frequent in the population over time.
