Answer:

spherical shape

Explanation:

Left: passive bloodstains. Right: bloody shoe print transfer pattern. Because blood demonstrates surface tension, or cohesive forces that act like an outer skin, a drop of blood dropped at a 90° angle forms a near-‐perfect spherical shape.

You have isolated a new mutation in the T4 bacteriophage rII A gene and you map its location within the gene by recombination fr
pantera1 [17]

Answer:

A lethal mutation, thereby the resulting phenotype is not observed .

Explanation:

Lethal mutations are the result of genomic changes that may be lethal in certain conditions. In genetic research, this type of mutation has shown to be very useful in analyzing gene function (i.e., genes whose protein products are key for the survival of the organism in question), and they are perfect gene markers. In bacteriophages, for example, temperature-sensitive mutants of phage T4 that can not grow at temperatures higher 42°C have been identified (Edgar & Lielausis 1964).

Help me with this question plsssss answer this in a complete paragraph
sweet-ann [11.9K]

Answer:

It's possible.

Explanation:

It said if they were nearly as smart as humans. They never said if they were as capable as Humans. Naturally, some would be smarter than others so some might be able to live here but others might have to have their own country. So, it is likely that some Neanderthals will be able to live in modern society, though not all.
