Answer:
The photosynthetic rate refers to a determination of maximum rate at which leaves possess the tendency to fix carbon at the time of photosynthesis. The simple way by which the photosynthetic rate can be determined is by measuring the concentration of carbon dioxide produced.
It is known that the concentration of carbon dioxide, light intensity, and temperature are the three main elements, which affect photosynthesis. The enhanced concentration of carbon dioxide and higher light intensity results in higher photosynthetic rates.
In the given case where Elodea is used to study photosynthesis, it can be seen that at high light intensities, the concentration of bubbles increases as there is an elevation in the concentration of carbon dioxide.
Answer: Kids get their traits genetically from their parents. Their parents pass down genes that give their kids similar traits to their parents. Depending on which genes are dominant in the family, the kid will inherit those traits.

Organelles can have different sizes from each other. As related to the cell, they are smaller than the cell they are contained in, and at different microscope amplifications, there can be seen different organelles, more and more as the amplification increases.
An investigative question related to this could be:
What is the cell-specific organelle size relation, and the organelle X-organelle Y size relation when in different microscope amplifications.
Answer:
If I were to choose a plant or animal which is interesting, I'd choose the "cactus."
Explanation:
A "cactus" is truly a splendid plant owing to its <em>ability to survive in the desert </em>or<em> periods of drought.</em> Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.
- One of these threats is the <em>"over-collection of cacti." </em>Due to its versatile use, the cactus is often sold as an ornamental plant.
- Another threat is the number of pests, such as <u>snails</u> and<u> slugs</u>, that attacks it yearly. It is a delicious food for<em> mealy bugs, red spider mites, gnats, flies, etc.</em>
- People often misunderstand the <u>cactus' water level need</u>s. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.
