When identifying the agent responsible for causing a disease, why is evaluation of colony morphology not enough?
Answer:
Some infectious diseases are distinctive enough to be identified clinically. ... Infections may be caused by bacteria, viruses, fungi, and parasites. ... Microbial Identification: Colony and cellular morphology may permit preliminary ... Diagnostic medical microbiology is the discipline that identifies etiologic agents of disease.
Explanation:
Microorganisms have antigens present on their surface, Antigen tests detect the presence of a microorganism directly so that doctors can diagnose an infection quickly, without waiting for a person to produce antibodies in response to the microorganism.
Evaluation of colony morphology is not enough as it is not a definitive test. colonies of different bacteria can look the same, so it can help narrow.
What is antigen tests?An antigen test is an immunoassays test used for the detection of a specific viral antigen that indicates current viral infections.
Hence, Antigen tests detect the presence of a microorganism whereas, Evaluation of colony morphology is not enough as it is not a definitive test.

Over a period of several decades ecologists conduct an investigation on the survival of a species of lizards
Answer:
To find out the impact of environment on the physical structure of lizard and natural selection.
Explanation:
Ecologists conduct an investigation on the survival of a species of lizards in order to study the impact of environment on the physical body of lizard and natural selection. The ecologists find out that environment has direct impact on the body structure of lizard. Those lizards that spend more time on the ground, have longer legs in order to run fast, while on the other hand, species that lives in the trees usually have shorter legs in order to easily climb on the trees so these body structure helps them in survival and movement.

Babies with very low or very high birth weight are less likely to survive. The graph shows the percentage of babies born at different weights.
A graph entitled Percentage of Babies born at Different Weights has weight in pounds on the horizontal axis, and percentage on the vertical axis. A small percentage of babies are born at the low and higher birth weights, and a greater amount are around 7 to 8 pounds.
Which statement is a valid claim that could be made using the data in the graph?
Directional selection is occurring because the graph favors an extreme.
Stabilizing selection is occurring because the average is favored.
Disruptive selection is occurring because the two extremes are favored.
Biodiversity variation is occurring because there is an increase in trait variation.

Someone suggested that everything to be sent to the base on the moon must be sterelized so that no bacteria of any kind are present.Do you think this is a good idea
Answer:
Yes.
Explanation:
Yes, it is a good idea by sterilizing everything because this sterilization process kills bacteria or other harmful microbes on the items and no chance of bacterial infection occurs in the base that is present on the moon. This sterilization process is very important in order to make the health of the crew members and scientists that lives in the base on the moon. If the bacteria or other harmful microbes enters in the base so its maintained environment will triggers its growth and infections in the humans so it is a good idea.

Explanation:
Number the steps from when a stimulus is received to when the body reacts.
_____ The stimulus is received by sensory receptors.
_____ Motor neurons cause muscles to contract so the body can react to the stimulus.
_____ The brain processes the information through interneurons.
_____ Interneurons transfer response information to motor neurons.
_____ Sensory neurons carry stimulus information to the brain or spinal cord.
Answer:
The correct answer is -
1 - The stimulus is received by sensory receptors.
2 - Sensory neurons carry stimulus information to the brain or spinal cord.
3 - The brain processes the information through interneurons.
4 - Interneurons transfer response information to motor neurons.
5 - Motor neurons cause muscles to contract so the body can react to the stimulus.
Explanation:
In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.
These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.
