the site of atapuerca in northern spain is one of the most important fossil hominin sites in europe. identify what the following

Temka [501]

There have be found some fossils of ancient remains over the years. What the fossils from Atapuerca revealed about the hominins living in Europe at this time is below:

The Skull is known to show Interbreeding that took place with neandertals and their relatively healthy population.

The Fragment shows that there was a possibility of cannibalism in that area.

It shows that possible cannibalism took place as there were Cutmarks on various hominin bones found at Atapuerca mirror.

The relatively healthy population was found out through the study of the dentition of the Atapuerca hominins by anthropologists. It gave them a view into their diet and overall health.

The interbreeding with the Neandertals was shown through the Nuclear DNA that was gotten from bones and teeth of bones found at Sima de los Huesos

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: A.Osmosis

madreJ [45]

Answer:

B.Active transport, because energy is being used to move molecules against the concentration gradient

Explanation:

Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.

Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.

Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.

If genetic drift is occurring you will be able to predict which allele will become more prevalent.

Blizzard [7]

Answer:

b. False

Explanation:

Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events. As happens at random, it is impossible to predict which allele will be prevalent in a population suffering from genetic drift.

Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent.

Thus limiting the genetic content of a particular group, restricted to the prevailing individuals. It is up to them, integration into another population, if an adaptation is maintained, or over time, from geographic and later reproductive isolation, constitution of a new species (principle of the founding species).

In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals.

During evolution, a hypothesis concerning the decimation of dinosaurs, which occurred around 66 million years ago, establishes not only the end of these animals, but of various life forms (including plants), due to a huge asteroid that would have reached planet, raising a dense cloud of dust resulting from the collision, compromising photosynthetic processes (dependent on solar energy), as well as the respiration and nutrition of organisms.
