What kind of adaptations could have given homosapiens an evolutionary advantage over neanderthals and other species of humans?
3241004551 [841]

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.

First way it will affect the environment is that there won’t be any trees to soak up water from rainstorms.

Second water won’t be brought up to the surface due to the fact there are no roots to do that.

Which of these are true regarding eukaryotes? (choose all that apply)
OleMash [197]

Answer:

b. During replication there is both a leading strand and a lagging strand .

c. Each replication bubble has two replication forks.

Explanation:

Eukaryotic chromosomes have multiple origins of replication to replicate the long chromosomes at a higher rate.

The two DNA strands have opposite polarity, that is, 5' end of the one DNA strand is present opposite to the 3' end of the other DNA strand. DNA replication occurs only in 5' to 3' direction and the direction of the movement of the replication fork is also 5' to 3' direction.

To allow the DNA replication in 5' to 3' direction on both strands, one strand is replicated discontinuously in the direction opposite to the movement of the replication fork.

The discontinuously replicated strand is lagging strand while the other one is the leading strand.

DNA replication in eukaryotes occurs bidirectionally as two replication forks are formed at each replication bubble, one at each end of the replication bubble.

The presence of multiple origins of replication and the bidirectional process allows the replication of large eukaryotic DNA at a considerable fast speed.

based on the pictures of homologous structures in each organism, what do you think a homologous structure is
Drupady [299]

A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor. In other words, it's when very different animals have bones that appear very similar in form or function and seem to be related.
