Answer:
humans had more developed 'social' brains than Neanderthals, which enabled us to colonize new habitats and adapt to climate fluctuations
Explanation:
A more developed brain is considered to be an adaptive advantage that enabled early humans to leave Africa and colonize new habitats. Modern humans are able to adjust to new environments, situations, and socialize with other humans because the brain is a social organ. Although Neanderthals were able to occupy an important area of Europe, H. sapiens could colonize faraway lands, migrating into tropical forests, deserts, and glacial lands (colder areas than those colonized by Neanderthals). These early humans formed social groups which enabled them to find food more easily, thus greatly increasing their chances for survival.
Well, it depends but adults can weigh up to 420,000 pounds
The answer is bonds between atoms break and new bonds form. In order for a chemical change to happen, a new substance/substances (products) have to form that have different properties from the reactants. The bonds in the reactants break and new bonds form in the products.
Hope this helps
Answer:
The correct answer is "The "host range" for a virus is determined by the presence or absence of particular components on the surface of a host cell that are required for the virus to attach".
Explanation:
The missing option of this question is the one that is correct, which is "The "host range" for a virus is determined by the presence or absence of particular components on the surface of a host cell that are required for the virus to attach". A virus is able to infect by recognizing particular components that are present in the surface of the host cell. If this components are absent in the cell, the virus is not able to infect it. Therefore, the "host range" is determined by the presence or absence of this particular components.
