How are ants so strong?
Rashid [163]
Hello!

Well, impressively but, as you can clearly see,the reason that all ants can lift so<span> much, or are very strong, is all because of their body size increases as a cube of length- while the cross sectional area of muscles increases as the square of length as seen.

By the way, as an extra fact, ants aren't only very strong, but extremely fast also! It is studied and estimated that </span><span>the average ant as known, can carry between 10 and 50 times its own </span>body weight!<span> and run at approximately 300 meters an hour, a rate of nearly 800 times its body length a minute! 

Very impressive right?

Some students want to test different soils to find out which ones absorb heat the fastest. For the first test, they put 500 gram
tankabanditka [31]

Answer:

Weight of the soil (500g)

Explanation:

According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.

In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.

This means that for the remaining soil being tested, 500g of each type of soil should be used.
