What type of mutation is shown in the DNA strand to the right given the original strand.
original - T A T G A C A A T ---> mutated strand - T A T C A C A A T
Group of answer choices
point mutation
deletion
insertion
translocation
Answers
Why? - A point mutation or substitution is a genetic mutation where a SINGLE nucleotide base is changed, inserted or deleted from a DNA or RNA sequence of an organism's genome.
Why not Insertion - In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping. ... On a chromosome level, an insertion refers to the insertion of a larger sequence into a chromosome. So, in short Insertion adds one nucleotide but not changes one nucleotide to another. Which is done by POINT MUTATION.
What relationship exist between amino acid and protein?
Answers
Explanation:
When connected together by series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on other interactions (dashed lines) between its amino acid side chains.
Amino acids are the subunits or monomers of proteins i.e. proteins are made up of amino acids.
WHAT ARE PROTEINS?
Proteins are one of the four major biological molecules in nature. Proteins are polymeric compounds made up of long chains of structures called AMINO ACIDS. Amino acids come together in a chemical reaction called CONDENSATION REACTION to form complex protein molecules. Each amino acid is linked to one another by a covalent bond called PEPTIDE BOND. Peptide bond is a kind of covalent bond that links two amino acids together. It forms between the amino group (-NH2) of one amino acid and carboxyl group (-COO) of anotherHence, amino acids are monomeric units of protein molecules.

What is the grizzly bear?
The grizzly bear is a North American subspecies of the brown bear. Grizzlies are typically brown, though their fur can appear to be white-tipped, or grizzled, lending them their name. Grizzly bears are protected by law in the continental United States—not in Alaska—though there have been some controversial attempts to remove those protections in recent years.

Which statement accurately describes how genetic information is transferred during meiosis?
Meiosis creates four daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates two daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates four daughter cells that have identical genetic information to the parent cells.
Meiosis creates two daughter cells that have identical genetic information to the parent cells.
Answers
Meiosis is the reductional division which creates four daughter cells that have identical genetic information to the parent cells. Thus, the correct option is C.
What is Meiosis?Meiosis is a special type of cell division which is also called as reductional division. This division takes place in the germ cells in sexually reproducing organisms which results into production of gametes, such as sperm or egg cells. Meiosis involves two rounds of division which ultimately result in the formation of four cells with only one copy of each chromosome or half genetic content.
Meiosis is divided into two divisions: Meiosis I and Meiosis II. In which, Meiosis II is similar to Mitosis and Meiosis I involves the reduction of genetic material to half.
Therefore, the correct option is C.

Answers
Solution, carbonation, hydration, oxidation, and reduction are significant chemical weathering reactions, hence options B and C are correct.
What is chemical weathering?Chemical weathering is the term used to explain how chemicals in rainfall alter the minerals in a rock. Rainwater becomes somewhat acidic as a result of the air's carbon dioxide being dissolved in it.
Weathering can result from an interaction between the minerals in the rock and precipitation.
Oxidation, hydrolysis, and carbonation are processes that take place during chemical weathering.
Therefore, hydrolysis is a reaction with water, carbonation is a reaction with CO₂ to generate a carbonate, and oxidation is a reaction with oxygen to form an oxide, hence options B and C are correct.

What explanation does science give about how the Mouflon found on an island in the Indian Ocean were able to maintain their genetic diversity under extraordinary circumstances?
Answers
Answer:
According to Dr. David Coltman, the models of the genetic drift predict that the genetic diversity of the Mouflon should have been lost with time. However, the genetic diversity of the species has been maintained as natural selection is more essential to the evolutionary procedure than is considered generally.

The extreme conditions of the island are considered to have inhibited genetic drift, due to this premium advantage, the more genetically diverse mouflon on the island hold over their less genetically diverse counterparts.Answer:
Dr. David Coltman, an evolutionary geneticist at the University of Alberta, says that although the models of genetic drift predict the genetic diversity of the Mouflon should have been lost over time. The genetic diversity of the Mouflon has been maintained because "natural selection is more important to the evolutionary process than is commonly believed," according to Dr. Coltman. The extreme conditions of the island are thought to have prevented genetic drift because of the premium advantage the more genetically diverse mouflon on the island hold over their less genetically diverse cousins...
(If this is an of several small islands near the coast of Iran then cross breeding with male aboriginal Iranian Muzzistock is sufficient to maintain diversity but has shown to be detrimental to both species as evidenced in the fall in diversity of the Iranian Moui population.
Given many subspecies exists-- some of which were quasi-domesticated, it is possible the gene pool was replenished via shipwreck survivors from Iranian/Persian pirate or merchant shipwrecks --as the sheep were often kept as ocean going companions, milk, and, meat sources. It also depends on the islands location and if there was a land bridge 10-12-16,000 years ago during the last maximum glacial.)

(50pts) The evolution of the peppered moth over the last two hundred years has been studied in detail. Originally, the vast majority of peppered moths had light coloration. However, because of widespread pollution during the Industrial Revolution in England, the dark colored moths became much more common.
Question:
What specifically caused the shift in phenotype of the moths? Please explain in detail.
Answers
Answer:
The peppered moth is a temperate species of night-flying moth. Peppered moth evolution is an example of population genetics and natural selection and not artificial selection.
Explanation:
Answer:
The phenotype of the moth changed due to natural selection. During the Industrial Revolution, objects in England became a lot darker in color due to the settling of coal pollutants in the air. These light colored moths did not have good camouflage in this environment. Therefore, most of the light colored moths did not survive to reproduce. However, the dark colored moths had better camouflage, and were therefore more likely to survive and reproduce. This lead to a shift towards darker color moths, as they had a higher survival rate than the light colored moths.
