Q: Which type of natural disturbance in temperate grasslands, can be caused by a lightning strike? Read this paragraph and choose the correct option from the provided answers: Fires, which are a natural disturbance in temperate grasslands, can be ignited by lightning strikes. It also appears that the lightning-caused fire regime in North American grasslands was enhanced by intentional burning by humans. When fire is suppressed in temperate grasslands, the vegetation eventually converts to scrub and dense forests. Often, the restoration or. Choices: - drought - mass extinction - avalanche - fire A:
fire

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:
(Answer)
intervertebral disc

Ques: Q: How do yeasts reproduce? Read this paragraph and choose the correct option from the provided answers: Yeasts are an exception. They reproduce asexually by budding instead of by producing spores. An offspring cell forms on a parent cell. After it grows and develops, it buds off to form a new cell. The offspring cell is genetically identical to the parent cell. You can see yeast cells budding in Figure below . Choices: - homosexual - preferentially - bisexual - asexually A:
Ans: asexually

(A).
toxicity

Ques:Q: What are monosaccharides and disaccharides also called? Read this paragraph and choose the correct option from the provided answers: An example of a disaccharide is sucrose (table sugar), which consists of the monosaccharides glucose and fructose ( Figure below ). Other common disaccharides include lactose ("milk sugar") and maltose. Monosaccharides and disaccharides are also called simple sugars . They provide the major source of energy to living cells. Choices: - simple chemicals - basic sugars - complex sugars - simple sugars A:

Ans:simple sugars

Q: Influenza is a type of what, where glycoproteins attach to a host epithelial cell? Read this paragraph and choose the correct option from the provided answers: Figure 17.6 In influenza virus infection, glycoproteins attach to a host epithelial cell. As a result, the virus is engulfed. RNA and proteins are made and assembled into new virions. Choices: - recent disease - nucleus disease - atoms disease - viral disease A:
viral disease
