Answer: Option A.
Charles Darwin proposed the theory of natural selection as a mechanism of evolution.
Explanation:
Charles Darwin was an English naturalist that lived between 1809 and 1882. He proposed a theory of evolution and natural selection. The theory states that all living organisms came from and develop through the natural selection of small, inherited variation that increase individual's ability to compete, survive and reproduce.
Food, water, shelter, predation, and density are all things that can allow a population to increase or cause it to decrease. Limiting factors like food and water are necessary resources for all organisms without them they will die so these factors directly affect any population size. Hope this helps :)
Answer:
The correct answer is - sex and blood type.
Explanation:
Different organisms have different traits some are passed from the parents and other traits are developed by environmental influences. The traits that are passed from parents to the offspring are determined by the genes they inherited from the parents. In humans, sex is determined by the genes that present on the chromosomes and make the chromosome X chromosome or Y chromosome. The presence of the Y chromosome determines maleness.
Similarly, the blood group is determined by the genes, there are three alleles of the ABO gene present on chromosome 9; A. B. and O each allele code for a different antigen which helps them categorizing in blood groups.
