Answer:

Catalysts

Explanation:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactioms. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy

Answer:

Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.

Svetradugi [14.3K]

Answer:

C. Charged, polar, or non-polar

Explanation:

Amino side chains, also called R groups, are classified into the categories of charged, polar, and non polar.

These classifications can be determined by the structure and elements within the R group/functional group.

15,000 years ago, when humans were foragers and hunters, what characterized daily life? What were humans eating, and where and h
lisabon 2012 [21]

1. 15,000 years ago the humans were still hunter-gatherers. Their daily lives were largely based around one thing, finding enough food to survive through  the next few days. This means that they had to constantly be on the move, be it for hunting animals, or for finding rich places with eatable plants. There was lot of walking, running, and scouting involved every day. It was a lifestyle of ''living through the day''.

2. During this period of time, the diet of the humans was consisted of animals they hunted, fish, and plants. There were differences from region to region though, so the people that lived along the coastline based their diet on marine animals, the ones that were living in colder regions were eating mostly meat, while the ones living in forested areas or grasslands had combination of plants and meat. The lifestyle in general was moving from place to place, be it on a daily basis, weakly, or seasonally, depending on the conditions. Some of these people were making small shelters, some of which were retractable and they were moving them with them, while others were using caves.

3. There are many difference between the forager peoples and the agriculturalists. The foragers were nomads, thus they were moving very often from one place to another, while the agriculturalists were having a settled lifestyle. The nomads very often had bad injuries which were often fatal, usually because of hunting, while the agriculturalists had much better health because they had much safer lifestyle. The foragers were not able to produce their own food, but instead they were relying on mother nature, while the agriculturalists were producing their own food and had the food problem solved.

Sickle-cell disease is probably the result of which kind of mutation?
sergey [27]

Answer:

Point mutation is the correct answer.

Explanation:

Sickle cell disorder is a genetic disorder that is caused because of point mutation.

Due to point mutation protein lose their function which results in sickle cell disease.

The mutation in the Hemoglobin Subunit Beta gene in Sickle cell diseases affects the hemoglobin and the red blood cells molecules that transfer oxygen to the cells.

Sickle cell diseases can lead to stroke, organ damage,blindness, priapism,hypertension, acute chest problems.

What differs among DNA structures of different species?
weqwewe [10]

Answer:

D) the arrangement of the nucleotides within genes

Explanation:

De-oxy ribo nucleic acid that is basically a polymer of nucleotides. Nucleotides are composed of three basic units: a de-oxyribose sugar unit, a phosphate group and nitrogenous bases that can be Adenine, Gunanine, Thymine and Cytosine.Adenine always pairs with Thymine and Guanine always pairs with Cytosine.

This is a universal composition of DNA in each and every living organism. The genes are a segment of DNA that contain specific sequence of nucleotides and encode for a specific trait of organism such as height, weight, eye color etc. The sequence of nucleotides expresses the trait in the form of protein product during the process of Translation. The products of translation are amino acids and every amino acids encode for a specific protein  in almost  all living organisms.

So, what differs in the specie is the sequence of nucleotides in genes. Infact this is the nucleotide sequence which brings evolution in organism and organisms evolve to form new specie with the passage of time. One major cause of change in nucleotide sequence is mutations due to which the organisms change with time.

Suppose the sequence of nucleotide of specific gene in organism A is

AAGGGGAAATTT

However in other specie organism B of same specie is:

TAGGGGAAATTT

This means only mutation of one base changed the gene in organism B and also its product called protein.

Hope it help!
