Answer 1

Answer: This would be the sum of all energy transfers within an organism.

Maintaining stability in an organism's internal environment is called homeostasis :).

Acetylcholinesterase is an enzyme that catalyzes the breakdown of the neurotransmitter acetylcholine. Which of the following explains why acetylcholinesterase cannot be used to catalyze the breakdown of other neurotransmitters, like norepinephrine?It would require a level of activation energy too high for acetylcholinesterase to react with other neurotransmitters. Binding with an alternate neurotransmitter would inhibit the reaction of the enzyme with acetylcholine. Reacting with another neurotransmitter would halt the production of the enzyme and raise the overall activation energy. Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered. I think it might be the last one

What did Thomas Hunt Morgan discover?

Answers

Thomas Hunt Morgan hoped to discover large-scale mutations that would represent the emergence of new species.

1910

Thomas Hunt Morgan (1866-1945) establishes the chromosomal theory of heredity

Thomas Hunt Morgan, an embryologist who had turned to research in heredity, in 1907 began to extensively breed the common fruit fly, Drosophila melanogaster. He hoped to discover large-scale mutations that would represent the emergence of new species. As it turned out, Morgan confirmed Mendelian laws of inheritance and the hypothesis that genes are located on chromosomes. He thereby inaugurated classical experimental

After breeding millions of Drosophila in his laboratory at Columbia University, in 1910 Morgan noticed one fruit fly with a distinctive characteristic: white eyes instead of red. He isolated this specimen and mated it to an ordinary red-eyed fly. Although the first generation of 1,237 offspring was all red-eyed but for three, white-eyed flies appeared in larger numbers in the second generation. Surprisingly, all white-eyed flies were male.

These results were suggestive for hypotheses of which Morgan himself was skeptical. He was at the time critical of the Mendelian theory of inheritance, mistrusted aspects of chromosomal theory, and did not believe that Darwin's concept of natural selection could account for the emergence of new species. But Morgan's discoveries with white- and red-eyed flies led him to reconsider each of these hypotheses.

In particular, Morgan began to entertain the possibility that association of eye color and sex in fruit flies had a physical and mechanistic basis in the chromosomes. The shape of one ofDrosophila's four chromosome pairs was thought to be distinctive for sex determination. Males invariably possess the XY chromosome pair (Morgan used a more cumbersome notation) while flies with the XX chromosome are female. If the factor for eye color was located exclusively on the X chromosome, Morgan realized, Mendelian rules for inheritance of dominant and recessive traits could apply.

In brief, Morgan had discovered that eye color in Drosophilaexpressed a sex-linked trait. All first-generation offspring of a mutant white-eyed male and a normal red-eyed female would have red eyes because every chromosome pair would contain at least one copy of the X chromosome with the dominant trait. But half the females from this union would now possess a copy of the white-eyed male's recessive X chromosome. This chromosome would be transmitted, on average, to one-half of second-generation offspring—one-half of which would be male. Thus, second-generation offspring would include one-quarter with white eyes—and all of these would be male.

Intensive work led Morgan to discover more mutant traits—some two dozen between 1911 and 1914. With evidence drawn from cytology he was able to refine Mendelian laws and combine them with the theory—first suggested by Theodor Boveri and Walter Sutton—that the chromosomes carry hereditary information. In 1915, Morgan and his colleagues published The Mechanism

• Discrete pairs of factors located on chromosomes like beads on a string bear hereditary information. These factors—Morgan would soon call them genes—segregate in germ cells and combine during reproduction, essentially as predicted by Mendelian laws. However:

• Certain characteristics are sex-linked—that is, occur together because they arise on the same chromosome that determines gender. More generally:

• Other characteristics are also sometimes associated because, as paired chromosomes separate during germ cell development, genes proximate to one another tend to remain together. But sometimes, as a mechanistic consequence of reproduction, this linkage between genes is broken, allowing for new combinations of traits.

Morgan's experimental and theoretical work inaugurated research in genetics and promoted a revolution in biology. Evidence he adduced from embryology and cell theory pointed the way toward a synthesis of genetics with evolutionary theory. Morgan himself explored aspects of these developments in later work, includingEvolution and Genetics published in 1925, and The Theory of the Gene in 1926. He received the Nobel Prize in Physiology or Medicine in 1933.

During the process of _____, mRNA decodes information from the original DNA master plan to build proteins in the ribosomes.

Answers

Ans. Translation.

Protein synthesis involves transfer of information from parent DNA to RNA by by the process of transcription and from RNA to protein by the process translation.

Translation occurs in ribsomes, during which information present in mRNA as triplet codons is used to synthesize polypeptide chains or proteins. Each genetic code codes for a specific amino acid and adds it to the growing polypeptide chain.

During the process of translation, mRNA decodes information from the original DNA master plan to build proteins in the ribosomes.

EOC Biology. A strand of DNA contains the sequence GGC-CAT. What is the complementary strand of mRNA for this sequence? Please help

Answers

GGC-CAT - strand of DNA
xxx- xxx - strand of mRNA
---------------------------------------------------------------------------
The first, let's see what connect with what:
when we talk about DNA and complementary strand of DNA:
guanine connects to cytosine (and vice versa)
thymine connects to adenine (and vice wersa)

when we talk about DNA and complementary strand of RNA:
guanine connects to cytosine (and vice wersa)
adenine (in DNA) connects to uracil (in RNA)
thymine (in DNA) connects to adenine (in RNA)
-----------------------------------------------------------------------------------------------
GGC- CAT - strand of DNA
CCG- GUA - complementary strand of mRNA

complementary strand of DNA would be: CCG- GTA
(in complementary strand of RNA: thymine is replaced with uracil)

Greetings,
n00nst00p :)

CCG-GUA :) (because its an mRNA strand it can't have the amino acid Thymine or (T) so we replace it with a U.

The water cycle is also referred to as the _______ cycle

Answers

Answer:

The correct answer would be hydrologic cycle (hydro means "related to water").

Hydrologic cycle or water cycle refers to the cyclic movement of water in an ecosystem.

The physical processes involved in the cycling of water throughout the ecosystem are: evaporation, condensation, sublimation, precipitation, infiltration, and runoff (surface and sub-surface).

Water evaporates from the surface of the earth into the atmosphere where they condense to form clouds. When temperature decreases, the water droplets merge with each other to form bigger droplets which are precipitated in the form of rain.

Water can also precipitate in the form of snow, fog, hail sleet et cetera.

Water fall on the earth surface either infiltrate to form ground water or runoff the surface to from lakes, rivers et cetera.

water cycle is also called hydrologic cycle
