Ques: Q: What is defined in physics as the amount of force pushing against a given area? Read this paragraph and choose the correct option from the provided answers: Particles of gas are constantly moving in all directions at random. As a result, they are always bumping into each other and other things. This is modeled in the Figure below . The force of the particles against things they bump into creates pressure. Pressure is defined in physics as the amount of force pushing against a given area. How much pressure a gas exerts depends on the number of gas particles in a given space and how fast they are moving. The more gas particles there are and the faster they are moving, the greater the pressure they create.

Ans: pressure

Q: Tuna have been shown to contain high levels of what metal? Read this paragraph and choose the correct option from the provided answers: The higher up a food chain that humans eat, the greater the levels of toxic metals they take in. That's why people should avoid eating too much of large fish such as tuna. Tuna are predators near the top of their food chains. They have been shown to contain high levels of mercury. In people, heavy metals can damage the brain and other organs. Unborn babies and young children are most affected. That's because their organs are still developing. Choices: - cadmium - titanium - iron - mercury A:
(A).
mercury

Ques:Q: What separates and strongly unites bodies of adjacent vertebrae? Read this paragraph and choose the correct option from the provided answers: General Structure of a Vertebra Within the different regions of the vertebral column, vertebrae vary in size and shape, but they all follow a similar structural pattern. A typical vertebra will consist of a body, a vertebral arch, and seven processes (Figure 7.23). The body is the anterior portion of each vertebra and is the part that supports the body weight. Because of this, the vertebral bodies progressively increase in size and thickness going down the vertebral column. The bodies of adjacent vertebrae are separated and strongly united by an intervertebral disc. The vertebral arch forms the posterior portion of each vertebra. It consists of four parts, the right and left pedicles and the right and left laminae. Each pedicle forms one of the lateral sides of the vertebral arch. The pedicles are anchored to the posterior side of the vertebral body. Each lamina forms part of the posterior roof of the vertebral arch. The large opening between the vertebral arch and body is the vertebral foramen, which contains the spinal cord. In the intact vertebral column, the vertebral foramina of all of the vertebrae align to form the vertebral (spinal) canal, which serves as the bony protection and passageway for the spinal cord down the back. When the vertebrae are aligned together in the vertebral column, notches in the margins of the pedicles of adjacent vertebrae together form an intervertebral foramen, the opening through which a spinal nerve exits from the vertebral column (Figure 7.24). Choices: - synovial fluid - collagen fibers - interstitial fluid - intervertebral disc A:

Ans:intervertebral disc

Question: Q: What is the transfer of information from rna to dna called? Read this paragraph and choose the correct option from the provided answers: Reverse transcription is the transfer of information from RNA to DNA. The is the reverse of normal transcription. Reverse transcription occurs in retroviruses, such as HIV, the virus that causes AIDS. Retroviruses are RNA viruses that are duplicated in a host cell by using reverse transcriptase enzyme to produce DNA from its RNA genome. Choices: - confront transcription - forward transcription - reverse differentiation - reverse transcription A:
Answer:
reverse transcription
