If a muscle fiber were to suddenly and permanently stop producing ATP the fiber would no longer be able to actively transport calcium out of the cytoplasm (sarcoplasm) and the intracellular calcium concentration would rise. You expect what to happen
No muscle contraction will be observed.
What is the effect of calcium concentration on muscle contraction?The concentration of calcium ions in the muscle cells help in contraction and relaxation of muscles fibers.
Release of calcium ions initiate muscle contraction.
Therefore, there will be no contraction of muscle if calcium ions are not transported out from the sarcoplasm.

How does biodiversity affect ecosystem stability?
A. Not all ecosystems are effected in the same way
B. Biodiversity has no effect on stability
C. More biodiversity increases stability
D. More biodiversity decreases stability
The ecology is absolutely necessary for biodiversity. Ecosystem stability also rises as a result of increased biodiversity.
What do you mean by biodiversity?
The term "biodiversity" is used to describe the variety of species that can be found on earth. It can include things like plants, animals, bacteria, fungi, and microbes. The diversity of life on earth is immense; while many species are still waiting to be discovered, many more have already gone extinct. The ecosystem is composed of every single living thing. It also covers their surrounding environment and how people interact with them.
The ecosystem depends heavily on the various species. Therefore, the ecosystem's ideal balance is impacted when a single species goes extinct or is lost. Plants use the energy from the sun as part of the ecosystem's cycle.

Select all the correct answers.
A) Plants with short stems are homozygous for that trait.
B) Plants with tall stems are always homozygous for that trait.
C) Both parent plants in the second generation are heterozygous.
D) Both parent plants in the second generation are homozygous.
The correct answers are options A and C.
How, explain your answer briefly?The Statement A says that the plants, which have a short stem is homozygous for the trait. According to the question, the allele for the short height is recessive. A recessive trait can only be observed, when the dominant allele is not at all present. Hence, the plant must have tt allele, so, the plant having short stem would be homozygous recessive.
The statement C says that the both parents in second generation are heterozygotes. It is given that the parents in the second generation have aa genotype Tt. In this case, both the alleles are different, hence, the parent plants are heterozygotes.

Consider these versions of The War of the Worlds. Excerpt 1, from H. G. Wells's novel The War of the Worlds: The common round the sand pits was dotted with people, standing like myself in a half-fascinated terror, staring at these creatures, or rather at the heaped gravel at the edge of the pit in which they lay. And then, with a renewed horror, I saw a round, black object bobbing up and down on the edge of the pit. It was the head of the shopman who had fallen in, but showing as a little black object against the hot western sun. Now he got his shoulder and knee up, and again he seemed to slip back until only his head was visible. Suddenly he vanished, and I could have fancied a faint shriek had reached me. Excerpt 2, from Howard E. Koch's script for Orson Welles's radio adaptation: PHILLIPS: Ladies and gentlemen, you've just heard Mr. Wilmuth, owner of the farm where this thing has fallen.

Answer:
Normal Strand: alanine - methionine - histidine
Mutated Strand: glutamine - cysteine - no third amino acid.
Explanation:
Messenger ribonucleic acid (mRNA) is the RNA that is used in cells for protein synthesis. It has a single strand made by the transcription of DNA by RNA polymerase. It contains four nucleotides: Adenine (A), Guanine (G), Cytosine (C), and Uracil (U).
Before transcribing, we need to create the complementary strand of the DNA. We're going to write out the nucleotides of the complementary strand by matching the nucleotides in these pairs: (A & T) and (C & G).
Normal Strand: GCA ATG CAC
Complementary Strand: CGT TAC GTG
Next, we can transcribe this to find our mRNA. We're going to do the same thing to the complementary DNA strand, but with Uracils instead of Thymines. So our pairs are: (A & U) and (C & G)
Complementary DNA Strand: CGT TAC GTG
mRNA Strand: GCA AUG CAC
You'll notice that the mRNA strand is almost exactly like the new mRNA strand, but with Uracil instead of Thymine.
Each set of three nucleotides is known as a codon, which encodes the amino acids that ribosomes make into proteins. To read the codons, you need to have a chart like the one I attached. Start in the middle and work your way to the edge of the circle. Some amino acids have multiple codons. There are also "stop" and "start" codons that signify the beginning and ends of proteins.
mRNA Strand: GCA AUG CAC
Amino Acids: Ala Met His
Our sequence is alanine, methionine, and histidine.
A frameshift mutation occurs when a nucleotide is either added or removed from the DNA. It causes your reading frame to shift and will mess up every codon past where the mutation was. This is different than a point mutation, where a nucleotide is swapped because that will only mess up the one codon that it happened in. Frameshift mutations are usually more detrimental than point mutations because they cause wider spread damage.
Let's repeat what we did earlier on the mutated strand to see what changed.
Mutated Strand: CAA TGC AC
Complementary Strand: GTT ACG TG
---
Complementary DNA Strand: GTT ACG TG
mRNA Strand: CAA UGC AC
---
mRNA Strand: CAA UGC AC
Amino Acids: Glu Cys X
---
Our amino acid sequence is glutamine, cysteine, and no third amino acid.
As you can see, removing the first nucleotide of the strand caused every codon to change. The last codon is now incomplete and won't be read at all. If this happened in a cell, the protein that was created from this mutated strand would be incorrect and may not function completely or at all.
