Answer:
Both options are valid, since in the hypothesis of the savanna it was argued that humans acquired bipedalism to be able to self-supply their food more effectively, and to have less body surface area exposed to the sun.
Explanation:
The saban hypothesis is believed to have originated in the saban, with the Austrolopitecus africanus being forced to affect this domain, which is why it acquired this adaptation mechanism.
The savanna had high grasslands, which also led to collaboration in this regard since they could be better camouflaged.
In addition, the human began to defend with the limbs of the upper limb, triggering the canines to decrease in size since it is not used as a defense mechanism.
The canine is a tooth that helps to tear carnivorous food, that is why the human also begins to have a more varied diet of fruits and seeds and that it can reach and take the bones of the tree to increase its height due to bipedalism.

<u>Answer:</u>
<em>The measurement 100.5 mL has 4 significant figures.</em>
<u>Explanation:</u>
Significant figures are defined as the digits that provides information in order to maintain accuracy and precision of a measurement. <em>Any nonzero number, trailing zeros with a decimal point and zeros between two numbers are recognizes as significant digits. </em>
Whereas, the figures which do not contribute to sustain the accuracy and precision of the measurement are insignificant figures.
<em>The leading zeros in any digit and the trailing zeros without decimal are considered as insignificant figures. </em>
<em>As in 100.5 1, two zeros and 5 after a decimal is significant figure which are 4 in total.</em>
