Ques:Q: What type of fibrous joint is found between most bones of the skull? Read this paragraph and choose the correct option from the provided answers: 9.2 | Fibrous Joints By the end of this section, you will be able to: Describe the structural features of fibrous joints Distinguish between a suture, syndesmosis, and gomphosis Give an example of each type of fibrous joint At a fibrous joint, the adjacent bones are directly connected to each other by fibrous connective tissue, and thus the bones do not have a joint cavity between them (Figure 9.5). The gap between the bones may be narrow or wide. There are three types of fibrous joints. A suture is the narrow fibrous joint found between most bones of the skull. At a syndesmosis joint, the bones are more widely separated but are held together by a narrow band of fibrous connective tissue called a ligament or a wide sheet of connective tissue called an interosseous membrane. This type of fibrous joint is found between the shaft regions of the long bones in the forearm and in the leg. Lastly, a gomphosis is the narrow fibrous joint between the roots of a tooth and the bony socket in the jaw into which the tooth fits. Choices: - lobiture - aperture - trecature - suture A:

Ans:suture

Ques:Q: Birds have a relatively large heart and a rapid what? Read this paragraph and choose the correct option from the provided answers: To keep their flight muscles well supplied with oxygen, birds evolved specialized respiratory and circulatory systems. Birds have special air sacs for storing extra air and pumping it into the lungs. They also have a relatively large heart and a rapid heart rate. These adaptations keep plenty of oxygenated blood circulating to the flight muscles. Choices: - lifespan - blink rate - digestive process - heart rate A:

Ans:heart rate

Ques:Q: In multicellular organisms, mutations can be subdivided into germline mutations and? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - elective mutations - comparative mutations - resultant mutations - somatic mutations A:

Ans:
somatic mutations
