What is the savanna hypothesis? Group of answer choices Bipedalism was selectively favored because it helped our ancestors to st
Gnom [1K]

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.

Serhud [2]

Stem cells arise from the inner mass of the cell

Signalling factors trigger differentiation in stem cells

Genes that lead to the production of undifferentiated blood cells are activated

Signalling factors cause undifferentiated blood cells to produce red blood cells

Explanation:

Red blood cells are formed in the bone marrow. The precursor to the RBC is stem cell which is undifferentiated and pluripotent. The stem cell gets differentiated to form immature RBCs. Immature RBC then gets divided and becomes mature. Stem cell giving rise to RBC is called Haemoctytoblast. The process of erythropoiesis takes 2 days to form new  red blood cells
