Answer:
c.reflects evolutionary history.
Explanation:
The best classification system in biology is that that reflects evolutionary history, this is because more developed animals evolved from ancestors, this means that little modifications on the DNA happened over the course of million of years that created the animals that we know today, so this little differences would be relfected on a classification system.
Answer:
The basic difference between the kind of fertilization most common in aquatic and terrestrial animal is that terrestrial animal lay their sperm into the environment to fertilize eggs, while aquatic animals lay their eggs in the water bodies in order to carry out the process of fertilization, because the sperm of aquatic animals need water as a medium in order to travel and meet the egg present in the water bodies so that fertilization can occur.
Answer:
The correct answer is "chloroplasts and mitochondria".
Explanation:
Chloroplasts and mitochondria are two essential organelles because of its function of producing Adenosine triphosphate (ATP), the "molecular unit of currency". Chloroplasts are organelles that are found in plants and work in light conditions, whereas mitochondria could produce ATP in the dark. Since the biologist found that the heavier fraction could produce ATP in light it is very likely that it will have chloroplasts, while the light fraction that produces ATP in the dark would likely have mitochondria.
The speed of an object is the distance the object travels in one unit of time. To calculate the speed of an object, divide the distance the object travels by the amount of time it takes to travel that distance.

Answer:
C) DNase (DNA destruction)
Explanation:
Oswald Avery and colleagues strengthened scientific support that DNA was the transforming factor by replicating the Griffith experiment with some important differences in experimental design.
