Answer:
Double number of chromosome.
Explanation:
There are 16 chromosomes in G2 phase of the cell cycle because in G2 phase, the replication of DNA occurs which doubles the number of chromosome. It is a gap phase present between replication of DNA and mitosis so it contains 16 number of chromosomes in the cell. After mitosis, the chromosomes number distributed equally among daughter cells.
Blocks, Since water blocks sunlight, photosynthesis can't occur in deep waters, because sunlight is required for photosynthesis.
1. Calcium carbonate minerals are the building blocks for the skeletons and shells of mini marine organisms. It is important to ocean creatures because they make their shells out of this material. Examples of animal products that are primarily of calcium carbonate include seashells, egg shells, pearls, and notably coral
Answer:
Option-D
Explanation:
Plants are the organisms present on the Earth which can be easily marked with their green color. The green color is due to the presence of the chloroplast which encompasses the chlorophyll pigment.
The chlorophyll pigment has the ability to capture the sunlight energy which initiates the process of photosynthesis. The photosynthesis process utilizes Carbon dioxide gas and water to form glucose molecules.
The glucose molecule is then transported to the other parts of the plants like stem and roots where photosynthesis is absent and to obtain the energy, plant perform cellular respiration. The cellular respiration requires oxygen gas which acts as an electron acceptor molecule.
Thus, Option-D is correct.
Explanation: The basic idea of biological evolution is that populations and species of organisms change over time. ... Darwin also suggested a mechanism for evolution: natural selection, in which heritable traits that help organisms survive and reproduce become more common in a population over time.
