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.

levacccp [35]

Answer:

Explanation:

Bilateral symmetry is a type of body symmetry where the body is divided in to halves i.e refers to organisms that have body shapes which look like mirror images along the midline which is called the sagittal plane.

Hypoventilation is a process where little amount of air enter into the alveoli which result in a decrease in the amount of oxygen in the lungs and increase in carbondioxide produced by the lungs. It is caused by too shallow breathing or slow breathing.

Hemothorax is a condition where there is blood build up in the pleural space or chest wall and lungs.

Arrhythmias is a health condition where there is irregular heartbeat. That is the heart may beat to fast, too slow, or irregular heart rhythm.

Two positive integers are 3 units apart on a number line. Their product is 108.
Svetlanka [38]
The first integer as given in the question = m
Then
The second integer as described in the question = m + 3
Then the equation will be
m(m + 3) = 108
The correct option is option "A".
Now let us solve for "m"
m^2 + 3m - 108 = 0
m^2 + 12m - 9m - 108 = 0
m(m + 12) - 9(m + 12) = 0
(m + 12)(m - 9) =0
So the value of "m" is -12 and 9.

A hypothesis is a ___.
Aloiza [94]

Answer:

A hypothesis is a tentative/ preliminary statement of the relationship between two or more variables. <u>It is a specific, testable prediction about what you expect to happen in a study.</u>

Explanation:

In science, the hypothesis is an idea or explanation that you then experience/test through study and experimentation. Outside science, theory or guess can also be called a hypothesis. The hypothesis is nothing more than an unbridled, wild guess but less than a well-established theory.

So, we can conclude that <em>The hypothesis</em><u> is a simple statement that defines what you think the outcome of your experiment will be.</u>

<em>Hope</em><em> </em><em>this helps</em><em>.</em><em>.</em><em> </em>

<em>Good</em><em> </em><em>Luck</em><em>!</em>
