PLEASE HELP!!!! WILL MARK BRAINLIEST!!!!​

Answers

Answer:

yes, these are isotopes of nitrogen.

Explanation:

Any atom with the same number of protons, but a different number of neutrons is called an isotope. Nitrogen has 7 protons and 7 neutrons. If it had a different number of protons, it would be a different element. Since we know both elements A and B are Nitrogen and therefore both have 7 protons, that means they have 8 and 9 neutrons, respectively. Therefore, they are isotopes of Nitrogen.

Which of the following can you infer from the information in the table below? Hominid species Evidence H. Neandertalensis Physical features include skeleton suited for upright walking, hands, and large brains. Burial sites contain artifacts like flowers, food, and weapons. All fossils found have been radiocarbon dated to be 130,000 to 35,000 years old. H. Sapiens Walk upright, have thumbs used for making tools. Large brains Bury their dead ceremonially. Fossils found in sediment layers containing volcanic ash crystals that are 195,000 years old H. Neandertalensis and H. Sapien were able to mate and produce offspring. H. Neandertalensis is not a direct ancestor of H. Sapien. H. Sapien is a hominid branch that will become an evolutionary dead end. H. Sapien and H. Neandertalensis did not occupy the same geographic region.

Answers

We can infer from the information in the table below information about the evolution.

Evolutionary History of Modern Man

1) Modern shares a common ancestor with gorillas and chimpanzees.

2) Some species before sapiens sapiens, according to the evolutionary process, are:

AustralopithecinesErgasterRectusNeanderthalensis and  sapiens.

3) Australopithecines inhabited the arboreal savannas of Africa around 2.8 to 2.3 million years ago.

4)Several species of australopithecines were able to walk upright or semi and had small brains.

5) During this period, Africa was undergoing a series of environmental changes that transformed its arboreal savannas, inhabited by australopithecines, into open savannas.

6) Thus, the australopithecines began to be exposed to predators, due to the decrease in shelters. This fact led to the extinction of most australopithecines.

Only a few lineages were able to adapt and survive, allowing the emergence of hominids.

With this information, we can know a little more about the evolution process of the human species.
