Answer the following question given this paragraph: Did you know that blood is a tissue? Blood is a fluid connective tissue that is made up of red blood cells, white blood cells, platelets, and plasma. The cells that make up blood are pictured below ( Figure below ). The different parts of blood have different roles. Q: Blood is made up of red blood cells, white blood cells, platelets, and what else? Choices: - pathogens - hemoglobin - potassium - plasma A:
plasma

Answer the following question given this paragraph: Government policies and laws are needed to protect biodiversity. Such actions have been shown to work in the past. For example, peregrine falcons made an incredible recovery after laws were passed banning the use of DDT. Q: Peregrine falcons made an incredible recovery after laws were passed banning the use of what? Choices: - Carbaryl - miticide - Acetamiprid - ddt A:
ddt

Answer the following question given this paragraph: Steps of Virus Infections A virus must use cell processes to replicate. The viral replication cycle can produce dramatic biochemical and structural changes in the host cell, which may cause cell damage. These changes, called cytopathic (causing cell damage) effects, can change cell functions or even destroy the cell. Some infected cells, such as those infected by the common cold virus known as rhinovirus, die through lysis (bursting) or apoptosis (programmed cell death or "cell suicide"), releasing all progeny virions at once. The symptoms of viral diseases result from the immune response to the virus, which attempts to control and eliminate the virus from the body, and from cell damage caused by the virus. Many animal viruses, such as HIV (human immunodeficiency virus), leave the infected cells of the immune system by a process known as budding, where virions leave the cell individually. During the budding process, the cell does not undergo lysis and is not immediately killed. However, the damage to the cells that the virus infects may make it impossible for the cells to function normally, even though the cells remain alive for a period of time. Most productive viral infections follow similar steps in the virus replication cycle: attachment, penetration, uncoating, replication, assembly, and release (Figure 21.8). Attachment A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the hostand the cells within the hostthat can be infected by a particular virus. This can be illustrated by thinking of several keys and several locks, where each key will fit only one specific lock. Q: Symptoms of viral diseases result from what kind of response to a virus? Choices: - infection - pathogenic - mutation - immune A:
