Answer the following question given this paragraph: The Levels of Organization To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of which are hydrogen, oxygen, carbon, nitrogen, calcium, and iron. The smallest unit of any of these pure substances (elements) is an atom. Atoms are made up of subatomic particles such as the proton, electron and neutron. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. Molecules are the chemical building blocks of all body structures. Q: All matter in the universe is composed of one or more unique pure substances called what? A:
OPTIONS:
- atoms
- molecules
- compounds
- elements

Answer: elements

Question: Answer the following question given this paragraph: Fossils are a window into the past. They provide clear evidence that evolution has occurred. Scientists who find and study fossils are called paleontologists . How do they use fossils to understand the past? Consider the example of the horse, shown in Figure below . The fossil record shows how the horse evolved. Q: Scientists who find and study fossils are called what? A:
OPTIONS:
- biologists
- geologists
- anthropologist
- paleontologists
Answer: paleontologists

input with options: Answer the following question given this paragraph: Mutation Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. The appearance of new mutations is the most common way to introduce novel genotypic and phenotypic variance. Some mutations are unfavorable or harmful and are quickly eliminated from the population by natural selection. Others are beneficial and will spread through the population. Whether or not a mutation is beneficial or harmful is determined by whether it helps an organism survive to sexual maturity and reproduce. Some mutations do not do anything and can linger, unaffected by natural selection, in the genome. Some can have a dramatic effect on a gene and the resulting phenotype. Q: What term is used to describe changes to an organism's dna and are an important driver of diversity in populations? A:
OPTIONS:
- adaptations
- pathogens
- evolutions
- mutations
output: mutations

Q: Answer the following question given this paragraph: Fertilization joins two haploid gametes into a diploid zygote. Q: What process joins two haploid gametes into a diploid zygote? A:

OPTIONS:
- embryo
- fusion
- migration
- fertilization

A: fertilization

Answer the following question given this paragraph: Variation and Adaptation Natural selection can only take place if there is variation, or differences, among individuals in a population. Importantly, these differences must have some genetic basis; otherwise, selection will not lead to change in the next generation. This is critical because variation among individuals can be caused by non-genetic reasons, such as an individual being taller because of better nutrition rather than different genes. Genetic diversity in a population comes from two main sources: mutation and sexual reproduction. Mutation, a change in DNA, is the ultimate source of new alleles or new genetic variation in any population. An individual that has a mutated gene might have a different trait than other individuals in the population. However, this is not always the case. A mutation can have one of three outcomes on the organisms' appearance (or phenotype):. Q: Genetic diversity in a population comes from two main sources - sexual reproduction and what else? A:
OPTIONS:
- radiation
- education
- pathogen
- mutation
