Well if the temperature goes above 42°c the enzymes become denatured so the body cannot function and you will die. Their optimum temperature is 37°c which is your normal body's temperature. If the body temperature. is too low the enzymes will not work effectively.

How do you think that Karl von
sergey [27]

Answer:

Karl von Frisch is best known for two major discoveries about honey bees. First, he demonstrated that honey bees have color vision, and published these findings in 191*. Second, in 193* he showed that honey bees use a dance language to communicate food locations to other bees.

Explanation:

Figure 1. Grids for the color vision test. The training color, marked with T, is blue in both cases; all other squares are shades of gray. The left box shows how the grid appears to an animal with color vision. The right box shows how the same grid may appear to an animal without color vision. The training square appears to be the same shade of gray as other squares in the grid. If the test animal cannot see in color, it will confuse the training square with other squares matching its shade of gray.

This clever test for color vision can be applied to any animal which can learn to recognize a feeding station using visual patterns.

The dance language

von Frisch observed that once one honey bee finds a feeding station, many other soon appear at the same station. This suggests that the first bee recruits other bees to the food. How might honey bees recruit help in collecting food? von Frisch¹s discovery of the dance language of the honey bee required careful determination of the correlations between movements of bees inside the hive and the locations of feeding stations. He found two types of dance. The round dance (Figure 2A) causes bees to look for food a short distance (up to about 50 meters) from the hive. The waggle dance (Figure 2B) tells bees the direction and distance to fly to find more distant food sources. Scout bees use these dances to recruit assistance in collecting food resources.

An experiment measures the growth of crystals in a liquid solution aboard the space shuttle. A collection of bottles has the liq
Feliz [49]

The correct answer is option A, that is, the bottle with zero percent concentration.  

The control in the given case would have the liquid in it in the absence of any supplemented dissolved solute. So, as to find whether the solution is making the crystal formation or the liquid can do it by itself.  

The control refers to one element, which is not changed at all through the experiment, as its unchanging condition permits the association between the other variables being examined to be better comprehended.
