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.
The answer should be 3
Explanation:
One plant will for sure have red leaves, while the other two have a probability of having red and yellow leaves, and one plant will only have yellow leaves.
Yellow: Y
Red: y
Two plants: Yy
Although the Red is recessive so it's a smaller chance of it overpowering the yellow, the answer might also be 1.
The level of productivity in oceans can be explained by the fact that the volume of the global ocean is enormous.
The oceans cover about 70% of the earth. This makes the ocean to occupy the largest volume on earth.
In spite of this large volume, the productivity of the ocean is just about 55 billion tons.
This low productivity of the ocean is tied to its large volume and small amount of primary productivity.
