What were the first hominins? what was the evolutionary fate of the first hominins?
drag the descriptions to the appropriate hominin lineages.
a) pre-australopithecinerobust.
b) australopithecinesgenus homo.

A) Pre-australopithecinerobust.

B) Australopithecinesgenus Homo.

Explanation:

Pre-australopithecinerobust.

The few findings indicate that he walked with his back straight, but the shape of the foot, with the big toe directed inward (as in the hands) instead of being parallel to the others, indicates that he should walk leaning on the outside of his feet and he couldn't travel great distances

Australopithecinesgenus Homo.

The first hominids that are certain that they were completely biped are the members of the Australopithecus genus, this type of hominin thrived in the wooded savannas of East Africa between 4 and 2.5 million years ago with remarkable ecological success, as evidenced by the radiation he experienced, with at least five different species scattered from Ethiopia and Chad to South Africa.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
