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:
The membrane excluded the starch molecules, but the iodide ions diffused through
Explanation:
The diffusion of substances always occurs from the region of higher concentration to the region of their lower concentration.
According to the given information, starch is a large macromolecule. Reaction of iodide and starch turns iodide ions dark blue. Since the side A of the container turned dark blue, it means that iodide ions diffused through the membrane from side B to side A. It turned the side A dark blue.
If starch would have diffused from side A to side B through the membrane, the side B would also have turned dark blue. However, side B had a brown solution. Therefore, the large molecules of starch were not allowed to pass through the membrane.
Answer: it is only a hormone storage area that receives hormones from the hypothalamus for release
Endocrine glands are glands that secrete products, hormones, directly into the blood rather than through a duct. The pituitary gland is one of the major glands of the endocrine system but the posterior lobe itself serves only a storage area of hormone and do not do the function of a true endocrine gland which is to secrete hormones
