Answer:
Mutation.
Explanation:
Mutation in the organism's DNA that is passed on to the offspring is that main cause of heritable phenotypic change in some members of a population that reproduces asexually. Repeated exposure of Plasmodium that is sensitive to artesunate strain to increasing dosage of artesunate led to the development of resistance in plasmodium because the genetic mutation occur in the plasmodium that provide resistance against artesunate.
A unicellular eukaryotic organism that infects and lives in insects and vertebrates as a parasite is called plasmodium. They are single-celled organisms that undergo both types of reproductive life cycles.
The mutation caused a heritable phenotypic change in some members of a population of certain type of reproducing organisms.
The mutation in the plasmodium strain can be explained as:Some organisms of certain reproducing type happened to be mutated causing a heritable phenotypic change in their offspring's. When the plasmodium strain was repeatedly exposed to artesunate which altered some of the species in becoming resistant instead of being sensitive.The increased dosage or exposure caused a mutation in some type of certain reproducing strains causing them to be resistant to the amount.Therefore, the mutation caused the heritable phenotypic change.

The central dogma describes which of the following?
the process by which enzymes are modified after translation
the way DNA is replicated
the flow of genetic information
the way RNA is used as a template to make DNA
Answer:
The correct answer is - the flow of genetic information.
Explanation:
The process includes the flow of genetic information or instructions encoded in DNA used to make or turn to a final product that can be DNA or protein, known as the central dogma.
Mostly central dogma term use for the protein synthesis from the DNA that takes place in the two steps, transcription is the first converts DNA into RNA and the second translation that converts product of the first step that is RNA into Protein. DNA → RNA → protein.
Thus, the correct answer is - the flow of genetic information.
The central dogma describes the flow of genetic information. The correct option is C.
A key idea in molecular biology known as the core dogma outlines how genetic information moves through cells. It says that RNA is translated into proteins from transcribed DNA.
This idea emphasises how genes are expressed and proteins are made in living things by sequentially transferring genetic information from DNA through RNA to proteins.
The fundamental dogma excludes DNA replication, the reverse transcription of RNA into DNA, and the process of post-translational enzyme modification.
Thus, the correct option is C.

Point mutations resulting in a single amino acid substitution provided evidence that: Select one: A. The genetic code is a triplet code. B. The genetic code is overlapping. C. The genetic code is not overlapping. D. The genetic code is degenerate. E. tRNAs recognize codons.
Answer:
C. The genetic code is not overlapping.
Explanation:
The genetic code is nonoverlapping because each nucleotide can be part of only one codon or 'codeword' during protein synthesis. Therefore, a particular point mutation in the nucleotide sequence can result in only one amino acid modification. A nonoverlapping genetic code indicates that the same letter (i.e., the same nucleotide) can not be used for two different codons. The non-overlapping nature of the genetic code was discovered by Tsugita and Fraenkel-Conrat (1960) by observing point mutations in the tobacco mosaic virus.
A change or modification in the single nucleotide base of the genetic material is called a point mutation. It can be either addition, deletion or inversion.
The correct answer is:
Option C. The genetic code is not overlapping.
This can be explained as:
The point mutation in the amino sequence tells that the codons are not overlapping and a single nucleotide is a part of only a single type of codon.A single nucleotide can't be included in two codons.The same letters of the bases purines and pyrimidines are not a part of two different triplets.Therefore, point mutation tells that the genetic code is non-overlapping.

A woman with a straight hairline has as child with a man who is heterozygous
and has a widow's peak.
What is the mother's genotype?
Answer:
aa
Explanation:
A widow's peak is the dominant genotype so one must not have that trait. If it was presented then the woman would have the genotype.
A widow's peak is dominant so the man would be either AA or Aa. Since it stated that his is heterozygous (Hetero meaning two different), his genotype would be Aa (again since a widow's peak is the dominant, it only needs one dominant genotype)
Please :( Based on your knowledge of evolution, are humans evolving? Support your answer with factual evidence as to
why or why not
Answer:
Jesus made every one evalution is false
When Charles Darwin introduced the theory of evolution through natural selection 158 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields gradually established evolution's truth beyond reasonable doubt. Today that battle has been won everywhere—except in the public imagination. Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as “intelligent design” to be taught as alternatives to evolution in science classrooms. When this article first went to press in 2002, the Ohio Board of Education was debating whether to mandate such a change. Prominent antievolutionists of the day, such as Philip E. Johnson, a law professor at the University of California, Berkeley, and author of Darwin on Trial, admitted that they intended for intelligent-design theory to serve as a “wedge” for reopening science classrooms to discussions of God.
The good news is that in 2005 the landmark legal case Kitzmiller v. Dover in Harrisburg, Pa., set binding precedent that the teaching of intelligent design in U.S. public schools is unconstitutional because the idea is fundamentally religious, not scientific. The bad news is that in response, creationists have reinvented their movement and pressed on. When they lost the ability to claim that creationist ideas are valid science, they switched to arguing that they were only supporting “academic freedom.” Worse, to further obscure the religious roots of their resistance, they now push for “critical analysis” of climate change, cloning research and other scientific endeavors that they paint as culturally oppressive.Explanation:

Answer:
dna could be used for food by bacteria
Explanation:
not a beneficial reason
All of the following reasons are beneficial for prokaryotes to take up foreign DNA except the use of DNA as food by bacteria. Thus, the correct option is A.
What is DNA uptake?DNA uptake is defined as the conversion of exogenous, DNase-sensitive DNA into a DNase-protected state inside a bacteria. In gram-negative bacteria, this DNA uptake can be achieved by crossing the outer membrane. By contrast, in gram-positive bacteria, DNA uptake is similar to gram-negative bacteria with passage across the cytoplasmic membrane.
The uptake of DNA in bacteria is beneficial as it helps in the production of recombinants that can be used for various purposes. The DNA uptake can be used for the repairing of damaged DNA and chromosomes in patients of genetic disorders.
New genes with different functions can be introduced in organisms like bacteria.
