Question

1. if an elephant’s profile is run and it has a band that is 225 bp long, which population does it belong to?
2. building macromolecules - fill in the data table below

type of macromolecule | composed of (elements) | function | food source
carbohydrate | | |
protein | | |
fat/lipid | | |

1. using the data table of genotypes to the right, pick 1 cub and determine its possible parents.

cub #
mother:
father:
table with genotypes for females, males, cubs

1. explain how you determined who the parents were.
2. cycles: describe what biogeochemical cycling is. what are the 4 major cycles?

Explanation:

For question 34, biogeochemical cycling refers to the movement of chemical elements (like C, N, P, H₂O) through biotic (organisms) and abiotic (air, water, soil) components of ecosystems. The four major cycles are: 1) Carbon Cycle (moves C between atmosphere, organisms, soil, oceans); 2) Nitrogen Cycle (involves N fixation, nitrification, denitrification, cycling N for proteins/nucleic acids); 3) Phosphorus Cycle (moves P through rocks, soil, water, organisms, key for DNA/ATP); 4) Water Cycle (hydrologic cycle: evaporation, condensation, precipitation, runoff, cycling H₂O).

Answer:

Biogeochemical cycling is the movement of chemical elements between biotic (living) and abiotic (non - living) components of ecosystems. The four major cycles are the Carbon Cycle, Nitrogen Cycle, Phosphorus Cycle, and Water (Hydrologic) Cycle.
