It would be oraganic matter I think.
Answer:
1. 2.98m/s
2. 0.28m
Explanation:
The energy equation would work great in this scenario:
E=K+U. Since all of our energy comes from gravitational potential energy, and we are interested in finding the kinetic energy, all our mechanical energy must be in kinetic form, therefore:

We can use energy to find max height.
For energy, set the equation E=K+U as 437.7=(mass adult+mass senior)gh:

Although, the overall function<span> of the </span>cell<span> is the same, there are some important differences between </span>animal<span> and </span>plant cells<span>. The first difference is that </span>plant cells <span>have an organelle called chloroplast. Chloroplasts contain a pigment called chlorophyll (which gives the </span>plant<span> its green color).
</span><span>Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.</span><span>The lysosomes are the animal cell's "garbage disposal", while in plant cells the same function takes place in vacuoles.</span><span>Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.</span>
