D) Photosynthesis was carried out as cyanobacteria evolved. Oxygen is a product of photosynthesis.
Answer:
Option C. Glucose.
Explanation:
Glucose is produced when carbondioxode is entered
in the plant body from the surrounding air through stomata and water is absorbed by the plant from soil through roots in the presence of sunlight. This process is called photosynthesis which occurs in plants for the preparation of food materials. Here food refers to glucose molecules. Oxygen is also produced in this process.
The correct answer of the given question above would be option D. CHROMOSOMAL POTENTIAL. A change in the frequency of alleles in a gene pool can be explained by all of the following except the chromosomal potential. <span>A change in allele frequency is more likely to produce microevolution. Hope this answer helps.</span>
The answer should be the third option "number of protons and neutrons." The atomic mass of a element is equal to the amount of protons, and neutrons added together in that element. So for example if we are trying to find the atomic mass of hydrogen you would add the total amount of protons and neutrons together to find it's mass although it doesn't equal the exact amount of it's mass but it's close.
Hope this helps.
All the branches of science that deal with the scientific study of living organism are called life sciences. e.g; botany,zoology,anatomy,biochemistry,embryology etc..
