earthworms benefit the soil
Explanation:
Answer:
20 synthesis is correct because it is an active transport
Seasonal changes in carbon dioxide concentration with the highest levels measured in May and the lowest levels measured in October will affect the photosynthesis rate due it is a reactant which is required during photosynthesis.
<h3>What are the photosynthetic chemical reactants?</h3>
Photosynthetic chemical reactants are those materials required to carry out photosynthetic reactions which include carbon dioxide and water molecules. These materials are used to generate simple carbohydrates such as glucose and oxygen.
Photosynthesis also requires sunlight to excite the electrons of chlorophyll molecules in order to generate chemical energy (glucose)
Therefore, with this data, we can see that the photosynthetic chemical reactants include both carbon dioxide and water, thereby fluctuations in the levels of these materials will affect the photosynthesis rate and thus may lead to a decrease and or an increase in the amount of photosynthetic products (i.e. oxygen and also glucose).

It is <u>true </u>that i<span>n operant conditioning, many complex behaviors are learned through shaping.
This means that you learn many new things through consequences that you experience. So, for example, when you're a kid, you are constantly being told not to touch a hot stove. But given that you are small and inquisitive, you still touch it and burn your hand. After that, you learn that touching something hot is going to hurt you, so you learn not to do it through a consequence.</span>
