Answer:
true
Explanation:
Different bacteria like to grow at different temperatures. Thus, a microbiologist will incubate a particular strain of bacteria at its optimal temperature so that he can study it when it is healthy. By changing the temperature, he can study the bacteria while they are stressed. Organisms that grow best at human body temperature, which is approximately 37 degrees Celsius (98.6 degrees Fahrenheit), are called mesophiles. Those that grow in hot temperatures between 40 to 70 degrees Celsius (104 to 158 degrees Fahrenheit) are called thermophiles. Those that grow at hot temperatures above 80 degrees Celsius are hyperthermophiles. Those that live in very cold conditions are called psychrophiles.
Answer:
Humans rely heavily on pollinator bees to sustain food production globally. But for decades, the insects’ population has declined, in part because of pesticide use. If the die-off continues, it will have huge economic and public health consequences for people. William Brangham reports on groups that are working on innovative ways to save the world’s jeopardized bee population — or supplement it.
Explanation:
In metaphase I, the homologous pairs of chromosomes align on either side of the equatorial plate. Then, in anaphase I, the spindle fibers contract and pull the homologous pairs, each with two chromatids, away from each other and toward each pole of the cell. During telophase I, the chromosomes are enclosed in nuclei.
The correct answer is option C, that is, it makes its own food.
The autotrophs accumulate chemical energy in the form of carbohydrates, which they produce themselves. Food is the chemical energy accumulated in organic molecules. The majority of autotrophs convert sunlight to produce food, by the process known as photosynthesis.
Only three species groups, that is, plants, some bacteria, and algae possess the tendency to perform the process of photosynthesis. The autotrophs are also known as producers, they start the food chains and feed all the forms of life.
Answer:
The correct answer is - Continental polar air mass. The continental polar air masses are very big air masses that are very cold, and dry
