Answer the following question given this paragraph: Fossils are the preserved remains of animals, plants, and other organisms from the distant past. Examples of fossils include bones, teeth, and impressions. By studying fossils, evidence for evolution is revealed. Paleontologists are scientists who study fossils to learn about life in the past. Fossils allow these scientists to determine the features of extinct species. Paleontologists compare the features of species from different periods in history. With this information, they try to understand how species have evolved over millions of years ( Figure below ). Q: What are the preserved remains of animals, plants, and other organisms called? Choices: - skulls - rocks - basalt - fossils A:
(Answer)
fossils
Ques: Answer the following question given this paragraph: The expression of an organism's genotype is called its phenotype . The phenotype refers to the organism's traits, such as purple or white flowers. Different genotypes may produce the same phenotype. This will be the case if one allele is dominant to the other. Both BB and Bb genotypes in Table 6.1 have purple flowers. That's because the B allele is dominant to the b allele, which is recessive. The terms dominant and recessive are the terms Mendel used to describe his "factors. " Today we use them to describe alleles. In a Bb heterozygote, only the dominant B allele is expressed. The recessive b allele is expressed only in the bb genotype. Q: In a heterozygote with one dominant and one recessive allele, which is expressed? Choices: - dominant atoms - submissive allele - dominant elements - dominant allele A:
Ans: dominant allele

Ques:Answer the following question given this paragraph: The main organs of the cardiovascular system are the heart and blood vessels. Both organs contain valves. Valves also are found in plumbing systems. They can be turned on or off to control the flow of water. Q: The main organs of the cardiovascular system are the blood vessels and what else? Choices: - alveoli - capillaries - lung - heart A:

Ans:heart
Ques:Answer the following question given this paragraph: Some of the most interesting evidence for evolution comes from vestigial structures . These are body parts that are no longer used but are still present in modern organisms. Examples in humans include tail bones and the appendix. Q: What is the tail bone an example of? Choices: - invertebrate structure - parasitic structure - primordial structure - vestigial structure A:

Ans:
vestigial structure
