Answer:
Genetic drift
Explanation:
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time. These variations in the presence of alleles are measured as changes in allele frequencies.
Answer: The cells in a cytoplasm of the organellesare called cytosol.
Explanation:
Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles. Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus that holds genetic material as well as membrane-bound organelles.
The organelles that scientists believed that it originated by symbiotic relationships between primitive eukaryotes and certain prokaryotes is known as chloroplast. Chloroplast contain chlorophyll which capture energy from sunlight that is used in photosynthesis .This energy is converted to ATP and NADPH
