Answer - A
The ratio of a child with clear skin with that of freckled skin is 1:2.
When genotype rr mates with genotype Rr, the following genotypes are expected:
Rr = clear skin dominant
rr= freckled skin
The abiotic factors that could cause the sea cucumbers to
differ their distance from one another are temperature, time of the day, and
humidity. The biotic factors that could influence are the organisms around
these creatures. Furthermore, the independent variable in this study is the
time of the day where observed are the average distance between these sea
creatures and their output, the distribution of sea cucumbers as the dependent
variable.
Hypothesis: There is a link between the time of the day and the distance of sea cucumbers amongst each other.
If organisms can not adapt they become extinct.
Answer:
Photosynthesis.
Explanation:
Endosymbiotic theory may be defined as the theory that explain the evolution of the chloroplast and the mitochondria. The chloroplast is limited to the plant cells only.
The development of chloroplast proves to be beneficial for the plant cells. This makes the plant cells, autotrophic organism. The main site of the photosynthesis is chloroplast in plant cells. Chloroplast helps in the capture of sunlight and convert into the chemical energy.
Thus, the correct answer is option (B).
