A large brain allows humans to solve complex problems. This, in turn, has allowed humans with bigger brains to survive better than humans with smaller brains.

Across nearly seven million years, the human brain has tripled in size. The most likely the reason for the evolution of a larger brain in humans is that a larger brain allows humans to solve complex problems. Large, complex brains  enable humans to process and store a lot of information and to interact with each other and with their surroundings better. The  brain we now humans have is the largest and most complex of any living primate.

What might two controlled variables (constants) Lisa would use for this experiment? ​
zhuklara [117]

There is no context so I will just explain what a constant is:

In an experiment following the scientific method, a constant is a variable that cannot be changed or is purposely not changed during the experiment.

An example would be:

If a researcher wanted to study the effects of temperature on the growth and development of garden snakes, the experimental variable for the experiment would be temperature. All other variables would need to remain consistent to avoid invalid data. The size of the cage, amount of light, food and many other variables would need to remain constant to ensure accurate results and a valid study. Those variables are constants. Some variables are not under a scientist's control, but are still considered to be constants. These constants are called universal constants and include gravity, the speed of light and electronic charge. Universal constants do affect experiments but will be constant through an experiment without being controlled by the scientist.

Organisms that cause red tide when present in large numbers
mash [69]
Red tides are caused by an explosive growth and accumulation of certain microscopic algae, predominantly dinoflagellates, in coastal waters. Some species of dinoflagellates produce toxins that are among the most potent known to man.
