Ques: Answer the following question given this paragraph: Some bacteria are spread by vectors. A vector is an organism that spreads bacteria or other pathogens. Most vectors are animals, commonly insects. For example, deer ticks like the one in Figure below spread Lyme disease. Ticks carry Lyme disease bacteria from deer to people when they bite them. Q: What is an organism that spreads bacteria or other pathogens? Choices: - plane - section - arc - vector A:
Ans: vector

Ques: Answer the following question given this paragraph: Diagram of a Cytomegalovirus. The capsid encloses the genetic material of the virus. The envelope which surrounds the capsid is typically made from portions of the host cell membranes (phospholipids and proteins). Not all viruses have a viral envelope. Q: What encloses the genetic material of the virus? Choices: - mitochondria - nuclei - the spindle - the capsid A:
Ans: the capsid

Ques: Answer the following question given this paragraph: Sweat Glands When the body becomes warm, sudoriferous glands produce sweat to cool the body. Sweat glands develop from epidermal projections into the dermis and are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There are two types of sweat glands, each secreting slightly different products. An eccrine sweat gland is type of gland that produces a hypotonic sweat for thermoregulation. These glands are found all over the skin's surface, but are especially abundant on the palms of the hand, the soles of the feet, and the forehead (Figure 5.14). They are coiled glands lying deep in the dermis, with the duct rising up to a pore on the skin surface, where the sweat is released. This type of sweat, released by exocytosis, is hypotonic and composed mostly of water, with some salt, antibodies, traces of metabolic waste, and dermicidin, an antimicrobial peptide. Eccrine glands are a primary component of thermoregulation in humans and thus help to maintain homeostasis. Q: What do sudoriferous glands secrete? Choices: - water - moving - tissue - sweat A:
Ans:
sweat
