I don't know about the second sentence, is it possible you give me a bit more of a context then maybe i can be of help
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.
Answer:
8 electrons
Explanation:
This gives each hydrogen atom two electrons in its outer energy level, which is full. It also gives oxygen 8 electrons in its outer energy level, which is also full.

The haploid number of the chromosomes should be 32.
Diploid number means that they have the complete sets of chromosomes in their cells, these cells are usually found in somatic (body) cells and different organisms have a different number. For example, a human somatic cell has 46 chromosomes, such as a muscle cell, or a skin cell etc.
Meanwhile, haploid number means that the number of chromosomes in the cell only have half of the chromosome number than that of the diploid cells. These haploid cells are usually found in gametes of sexually reproducing organisms, such as human, we have 23 chromosomes in our sex cells. This is important because we have to make sure the chromosome number of offsprings are not doubled, as during sexual reproduction, male and female gametes fuse together to form a zygote.
Therefore, to calculate the haploid number of a cell, we can divide the diploid number by 2, which is 64/2, and the answer would be 32.
Answer: it's C
Explanation: At the same time, the Southern Hemisphere is tilted away from the sun and experiencing winter. The summer season begins in the Northern Hemisphere on June 20 or 21, known as the summer solstice, when the axis of rotation is tilted a full 23.5° toward the sun.
