The brucellosis disease is mainly occur by the contamination of food that includes the unpasteurized milk and raw meat. The brucellosis is caused by the bacteria of the genus <em>Brucella.</em>
The symptoms of brucellosis includes chilies, appetite loss and back pain. The chief diagnostic symptoms includes the recurring of fever at the 24 hours of the interval.
Thus, the correct answer is option (C).
Answer:
Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas.
Explanation:
Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas are the three other environmental conditions besides high elevation that might result in adaptation to hypoxia. These abilities will increase the resistance to lower oxygen levels in the surrounding environment. Fish is the organism which used these types of adaptation for their survival in the surrounding of low oxygen levels.
Answer:
Maintaining an appropriate temperature is beneficial to an organism because <em>enzymes need a proper range of temperatures to catalyze vital reactions.</em>
Explanation:
Almost all the processes which occur in the body require enzymes so that the reactions can be catalyzed. Enzymes have a specific temperature range at which they can work. The temperature at which an enzyme works best is called as the optimum temperature for that enzyme.
If there is a vast change in temperature, then the enzyme will become denatured and will not be able to perform their prescribed function.
Answer: a. The amount of artificial daylight the colonies are exposed to
d. The amount of food available for foraging
Explanation:
The independent variable is the variable that can be changed and manipulated in an experiment. This is likely to bring variations in the experimental variable of the experiment.
In the given situation, the two variables artificial daylight and available food can be controlled to eliminate the variations in the experimental outcome. For example, the intensity of the light may affect the colonization of ants and the amount of food also may either increase or decrease the population of ants.
