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

Answers

Answer 1

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.

What is the relationship between genes DNA and proteins

Answers

Answer:

Although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits. While your genetic makeup does indeed determine physical traits like eye color, hair color and so forth, your genes affect these traits indirectly by way of the proteins created via DNA.

Hopefully, this answer helped! :D

Answer:

Most genes contain the information require to make proteins. The type of RNA that contains the information needed to make protein is called a messenger RNA or mRNA and it carries the message from the DNA out of the nucleus into the cytoplasm

How does ATP structure relate to its function?

Answers

Answer:

The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups. ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.

Answers

Answer:

Cellular respiration is similar to combustion because both reactions rely on fuel (reducing and oxidizing agents) to start the reaction; the difference is that in cellular respiration, enzymes are used during the reaction. Both result in smoke (CO2 and H20) and energy.

It increases the time it takes for the person to stop. It decreases the time it takes for the person to stop.

Answers

Answer:

C

Explanation:

Just took the test and the answer is C, It increases the time it takes for the person to stop.

The air bag minimize the force acting on a person during a collision due to decreasing the time it takes for the person to stop.

How air bag minimize the effect of force during collision?

Air bags are used in vehicles because they are able to minimize the effect of the force during a collision. Air bags minimize the effect by extending the time required to stop the momentum of the driver and passenger.

So we can conclude that air bag minimize the force acting on a person during a collision due to decreasing the time it takes for the person to stop.

Which of the following is an example of specific immunity?

Answers

Answer:

Immunity to Small Pox

Explanation:

Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

Answer:

Bacteriophage  

Explanation:

Bacteriophage is nothing but a virus that harms and kills the bacteria.

The Hershey-Chase Experiments is a well known experiment done by scientist, Alfred Hershey and Martha Chase. They conducted the experiment in the year 1952.

It was an extra ordinary experiment which made the world believe that the DNA is the genetic material and not a protein. In their experiment, they tried to find out if the protein coat or the core of the DNA of the virus which enters into the infected cells would help them to understand whether the genes were made of DNA or of protein.

They used sulfur-35 and phosphorus-32 radioactive isotopes to trace the DNA and the proteins.

Answer:

Explanation:

Hershey and Chase started with a virus called a bacteriophage.

They used the radioactive isotope sulfur-35 to label the protein

of the virus and phosphorus-32 to label the DNA of the virus.

They allowed the tagged virus to infect bacteria and studied the results. Hershey and Chase found that the only radioactive isotope within the bacteria was 32P.

This result indicated that the genetic material inserted by the virus to infect the bacteria was DNA.

Meiosis I is often referred to as reduction division because it results in the reduction of the chromosome number from diploid to haploid. The chromosomes that remain in each cell are made of sister chromatids. During meiosis II, what will happen to the sister chromatids?

Answers

Answer: they will separate into different cells.

Explanation:

They separate into 4 cells.

Sister chromatids separate during meiosis II, resulting in haploid cells with non-duplicated chromosomes.

What is sister chromatid?

A sister chromatid is two identical copies of a chromosome formed by DNA replication, with both copies joined together by a common centromere.

To put it another way, a sister chromatid is 'one-half' of a duplicated chromosome. A dyad is a pair of sister chromatids.

Meiosis II is analogous to mitosis. There is, however, no "S" phase. Because of recombination, the chromatids of each chromosome are no longer identical.

Meiosis II separates the chromatids, resulting in two daughter cells with 23 chromosomes (haploid), each with only one chromatid.

Thus, during meiosis II, there will be the separation of the sister chromatids.

The shape of each of the molecules is important because A) if the shape of any molecule in an organism changes, the DNA in that organism will also change B) the shape of a molecule determines the age of an organism C) the shape of a molecule determines how it functions in chemical reactions D) molecules having different shapes are always found in different organisms

Answers

Answer:

The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions

Explanation:

The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.

The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in  shape there would be no life existed.

Thus, the correct answer would be - C)

Permafrost is a permanently frozen layer on or under Earth's surface. It consists of soil, gravel, and sand, usually bound together by ice. ... Permafrost covers approximately 22.8 million square kilometers (about 8.8 million square miles) in Earth's Northern Hemisphere. Frozen ground is not always the same as permafrost.

or try this,

Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer".
