What is the best description of the following list? 1. eye color 2. height 3. hair color 4. ear shape a) learned traits that can be acquired through practice b) personality traits learned by watching other organisms c) physical traits that parents could pass on to offspring d) natural traits that are randomly passed on to organisms

C seems to be the most logical because A & B do not relate to physical characteristics, and these traits are not nessassarily random, so I would disregard D. :) Hope that helps!

can you attach a picture of the lettuce? : )

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
