Answer: b. one atom transfers an electron to another atom
Explanation:
An ionic bond is also called as the electrovalent bond. It is a type of linkage that is formed by the electrostatic attraction formed between ions of opposite charge in a chemical compound.
These bonds are formed when the valence electrons from one of the atom are transferred to the another atom.
These are all true except <span>"D. Natural selection usually causes a species to change suddenly," which is false. Natural selection and the subsequent changes to a species takes many thousands of years to have observable results. </span>
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.
Both are under the phylum annelida
Polychaeta are more numerous than oligochaeta
Example of polychaeta is sand worm
While oligochaeta is earth worm
Both are free living organisms
Answer:
The answer is:
A) Its measures are based on divisions that are powers of ten.
Explanation:
The explanation for why this is the answer is that it is true and obvious that the metric measurement system relies on certain divisions and prefixes that are based on the powers of ten such as "centi-" or "milli-". In short, the metric measurement system's basis is being able to have it's measures somewhat "altered" or "adjusted" by these particular prefixes to fit the item or subject or object being measured.
