Only plants can carry out photosynthesis and they must get
carbon dioxide from the air
Carbon dioxide is the source of carbon for photosynthesis
Carbon dioxide is only available in the air
Water for photosynthesis can be obtained by photosynthetic
organisms from anywhere in their surrounding environment

Why was the sample heated in step 5? describe the chemical principles involved in the reasoning behind this step?

Identify the type of energy used in each action. the flexing of an arm muscle: a signal transduction process by a neuron: a ball at the top of a hill: 1. electrical energy 2. mechanical energy 3. gravitational potential energy

Research cheetahs on the internet what has contributed to this animal becoming "endangered" or "threatened." what animal you have chosen? -cheetah how long has the animal been endangered or threatened? what has contributed to this animal’s endangered or threatened status? why is it important to save this animal from extinction? after researching and gathering facts, write a 350-word letter from the point of view of an animal rights' activist. be sure to include at least five facts that you learned from your research.
