Correct answer: A). Gathering evidence
The scientific explanation uses measurements and observations in order to explain something in the natural world. The Scientist uses the scientific method to collect evidence in the experiment that is related to the hypothesis.
They can gather the evidence by just observing the natural world and its phenomena or by performing an experiment in the laboratory or by running a model.
Hence, the correct answer would be option A.
The answer is Llanos. Llanos or in Spanish it is called plains. These are wide grasslands stretching across northern South America and inhabiting western Venezuela and northeastern Colombia. The Llanos have a region of approximately 220,000 square miles, surrounded by the Andes Mountains to the north and west, the Guaviare River and the lower Orinoco River and the Guiana Highlands to the east, and the Amazon River basin to the south.
Because they would need to compete over resources.
Answer:
False
Explanation:
Genetic variation is the difference in the sequence of DNA in the individuals of a population and a heterozygote has more genetic variation that homozygote person because heterozygote has two different alleles of a gene while homozygous individual have two same alleles.
Heterozygotes have advantage over homozygotes because it protects the individual from many genetical diseases and increase the genetic variation by increasing the gene pool in the population. So higher fitness results in more genetic variation in the population therefore the statement is false.
