Answer:

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.

Answer:

A. Activated B - cells divide to form memory cells.

Explanation:

The vaccine contains the dead version of the respective virus, so that virus will be inactive and it will become easy for the WBC to kill it and antibodies will be formed.

This is done because if we get infected by the virus, our body cells (WBC) will remember that how they killed the first entered virus (the dead version) and it will be easy for them to kill the active virus as they know the antibodies which were formed to kill the inactive virus.
