Answer the following question given this paragraph: which the articulating surfaces of the bones contact each other. Also unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly against each other, allowing for increased joint mobility. Q: Unlike fibrous or cartilaginous joints, the articulating bone surfaces at what joint type are not directly connected to each other with fibrous connective tissue or cartilage? Choices: - proximal joint - knee joint - polymeric joint - synovial joint A:
synovial joint
Answer the following question given this paragraph: Each human somatic cell (a body cell, or every cell other than a gamete) normally has two sets of chromosomes, one set inherited from each parent. These cells are said to have a diploid number of chromosomes. Each set contains 23 chromosomes, for a total of 46 chromosomes. Each chromosome differs in size, from about 250 million nucleotide pairs on the largest chromosome (chromosome #1) to less than 50 million nucleotide pairs on chromosome #22. Each chromosome contains a specific set of genes, as well as regulatory elements and other nucleotide sequences, making each chromosome essential to survival. Q: How many sets of chromosomes does each somatic cell have? Choices: - one - four - six - two A:
two
Q: Answer the following question given this paragraph: Australopithecus afarensis is a human ancestor that lived about 3 million years ago. Q: Australopithecus afarensis is an ancestor of what primate? Choices: - lemurs - orangutans - gorillas - humans A:
A: humans
Question: Answer the following question given this paragraph: Grain boundaries. As a polycrystalline material solidifies, grains with irregular shapes form. The interfaces between grains constitute grain boundaries. (Squares represent unit cells within grains. Q: As a polycrystalline material solidifies, grains with irregular shapes form. the interfaces between grains constitute grain what? Choices: - waves - patterns - obstacles - boundaries A:
Answer: boundaries

Answer the following question given this paragraph: Many genetic disorders are caused by mutations in one or a few genes. Other genetic disorders are caused by abnormal numbers of chromosomes. Q: What type of disorders are caused by mutations in genes or abnormal numbers of chromosomes? Choices: - thyroid disorders - immune system disorders - emotional disorders - genetic disorders A:
**Answer**
genetic disorders
Answer the following question given this paragraph: Compounds that form from two or more nonmetallic elements, such as carbon and hydrogen, are called covalent compounds . In a covalent compound, atoms of the different elements are held together in molecules by covalent bonds. These are chemical bonds in which atoms share valence electrons. The force of attraction between the shared electrons and the positive nuclei of both atoms holds the atoms together in the molecule. A molecule is the smallest particle of a covalent compound that still has the properties of the compound. Q: Compounds that form from two or more nonmetallic elements are called what? Choices: - ionic bonds - valent bonds - hydrogen bonds - covalent bonds A:
covalent bonds
