B two organisms can have similar DNA but still look differently because of the way they adapt

Answer:

The correct answer is B). two organisms with similar dna.

Explanation:

The scenario that best provides evidence of evolution is the one that shows two organisms with similar dna because the fact that the dna is similar indicates that they have evolved in a different way, yet they are related according to the part of dna they share. The differences may be justified by the different ways they have adapted and evolved under similar circumstances in the same environment.

lys-0071 [83]

Answer: Precise measurements are important for Scientific Accuracy in order to get correct results

Explanation:

Precision is how close the Agreement is between repeated measurements under the same conditions. For example, if a measured value 36.7cm has three digits, or significant figures. Significant figures indicate the precision of a measuring tool that was used to measure a value

Accuracy is how close a measurement is to the correct value for that measurement.

When taking scientific measurements it is very important to be both precise and accurate. Bad equipment, human error can give inaccurate results.

Match each component of biodiversity to the example of how it contributes to ecosystem stability.
professor190 [17]

Answer:  

Genetic diversity: Some individuals in a population of wild rabbits are resistant to a new disease.

Ecosystem diversity: If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks.  

Species diversity:  Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation.  

Biodiversity of an ecosystem is usually explored by three diversities which are responsible for ecosystem stability they are : genetic diversity, ecosystem diversity and species diversity.

Genetic diversity is the variety of genes within a population of species. Each species consists of individuals bearing different genetic composition. Some individuals in a population of wild rabbits are resistant to a new disease because they exhibit genetic diversity within the population as a consequence some individuals exhibit genes which protect them against new disease.

Species diversity is the variety of species within an ecosystem. Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation is an example of species diversity. The wild rabbits from a forest and a neighboring meadow are two species living in an ecosystem stating the diversity of species in an ecosystem.

Ecosystem diversity is the variety of ecosystems in a given region.If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks is an example of ecosystem diversity because in an ecosystem there is interaction of organisms as predator prey relationship. This example is also relating with predator prey relationships in an ecosystem.

A scientist is using relative dating to determine the age of a fossil that she discovered.
Dmitry [639]

Answer: D.finding fossils in the same area that are in layers closer to the surface.

Relative dating refers to the age estimation method in which past events are determined, to compare the age of object, organism, strata or rock with the age of other similar entity. This method gives an approximate or estimated age, it does not provide absolute age.  

The older fossils are found in deeper layers of the strata as compared to younger fossils. This represents the geological time and life span of primitive or preexisting organisms. Therefore, according to the given situation, finding fossils in the same area that are in layers closer to the surface is the best conclusion.
