There are 4 thing that need to happen for natural selection to occur:
1) reproduction
2)heredity
3)variation in fitness or organisms
4)variation in individual characters of the population.
Spores are the reproductive cells that are better adapted to disperse or spread bryophytes and ferns to other places. They can be dispersed by wind.
Answer:
<em>The correct option is D) the rate of photosynthesis increases and then levels off.</em>
Explanation:
Photosynthesis can be described as the process by which plants make their own food from carbon dioxide and water by using light energy from the Sun. Oxygen is produced as a by-product of this reaction.
As we increase the intensity of light, the rate of photosynthesis also increases. But after a certain time, the reaction rate will level off as there might be enough food produced or the light energy might have caused the temperature to rise which would have caused the enzymes to get denatured.
