Answer the following question given this paragraph: White blood cells (WBCs) are usually larger than red blood cells. They do not have hemoglobin and do not carry oxygen. White blood cells make up less than one percent of the blood's volume. Most WBCs are made in the bone marrow, and some mature in the lymphatic system. There are different WBCs with different jobs. WBCs defend the body against infection by bacteria, viruses, and other pathogens . WBCs do have a nucleus and other organelles. Q: Where are most white blood cells made? Choices: - lungs - heart tissue - plasma - the bone marrow A:
the bone marrow

Answer the following question given this paragraph: The bodies of organisms can make a sedimentary rock. Plant bodies are lithified to become coal. When shells are cemented together they make a type of limestone. So limestone can be considered chemical or organic. Q: What is formed when plant bodies are lithified? Choices: - copper - fossils - methane - coal A:
(Answer)
coal
Ques: Answer the following question given this paragraph: Has this ever happened to you? You walk across a carpet, reach out to touch a metal doorknob, and get an unpleasant electric shock (see Figure below ). The reason you get a shock is because of moving electric charges. Moving electric charges also create lightning bolts and the electric current that flows through cables and wires. Q: Has this ever happened to you? you walk across a carpet, reach out to touch a metal doorknob, and get an unpleasant electric shock? .the reason you get a shock is because of what? Choices: - sunlight charge - temperature charge - solar charge - electrical charge A:
Ans: electrical charge

Ques:Answer the following question given this paragraph: Once again, a mutation is the change in the DNA or RNA sequence. In multicellular organisms, mutations can be subdivided into germline mutations and somatic mutations. Germline mutations occur in the DNA of sex cells, or gametes, and are therefore potentially very serious. These mutations can be passed to the next generation. If the zygote contains the mutation, every cell in the resulting organism will have that mutation. If the mutation results in a disease phenotype, the mutation causes what is called a hereditary disease. Somatic mutations , which occur in somatic, or body, cells, cannot be passed to the next generation (offspring). Mutations present in a somatic cell of an organism will be present (by DNA replication and mitosis) in all descendants of that cell. If the mutation is present in a gene that is not used in that cell type, the mutation may have no effect. On the other hand, the mutation may lead to a serious medical condition such as cancer. Q: In multicellular organisms, mutations can be subdivided into germline mutations and? Choices: - elective mutations - comparative mutations - resultant mutations - somatic mutations A:

Ans:
somatic mutations
