<span>As there are many kinds of deserts, some hot, some cold even arid deserts are the classic hot deserts, but there are also cold and coastal deserts where temperatures do not get so high. The element common to all of these types of deserts, however, is their lack of rainfall. In that sense the rainfall is a characteristic that determines if it's a desert.</span>
Answer:
The distribution of chloroplasts in each algae cell was approximately the same.
The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.
Explanation:
Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.
The wavelength of 475nm and 650nm are most effective in driving photosynthesis.
Answer;
-Disruptive selection
Disruptive selection results in the creation of two distinct phenotypes.
Explanation;
-Disruptive selection is a type of natural selection that selects against the average individual in a population. The make up of this type of population would show phenotypes of both extremes but have very few individuals in the middle.
-The variance of the trait increases and the population is divided into two distinct groups. The disruptive selection will cause organisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more.
