Explanation:
Behaviors that are determined by genes and that give an organism increased reproductive success usually become common in a
species due to <u> </u><u>evolution by natural selection,</u>
In<u> evolution by natural selection, </u>the following must occur
- reproduction
- the inheritance of specific traits from parent to offspring- heredity
- variations in the number of offspring each individual produces
- variations in physical characteristics
Further Explanation:
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.
During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial trails may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
This is called natural selection- an evolutionary mechanism which changes the inheritance frequencies of these beneficial alleles over several generations of offspring. These offspring are said to develop adaptations which ensure their survival, the alleles for which become more stable within a population over time.

Answer:
They contagious biohazard. They pose threat to human's health by causing Infection.
Explanation:
Biohazards are living organisms or microooganisms that affect humans health by releasing toxic materials or cause disease.
Round worm is a biohazard that affect humans. They can be parasitic, free-living worms. The parasitic worms are contagious and anyone can get roundworm Infection. Round worms are worms with a long round body. The parasitic roundworms affect the human intestines. Round worms are leading cause of morbidity in the world.
There are many of types of roundworms. And this include Raccoons and they are the primary host of Baylisascaris procyonis, a roundworm that can be harmful to people. The more round worms present in the body, the severe the symptoms will be.
Answer:D.
Explanation: Eukaryotic cells have a nucleus while prokaryotic cells dont. The nucleus store the DNA so that means that prokaryotic cells have their DNA floating around in them while eukaryotic cells have their dn6in the nucleus alone.
Answer:
diversity is the quality of being diverse or different
variation is the act or state of varying
