A swimmer dives underwater and needs to swim a long distance while holding her breath. This prevents her body from getting oxygen.
What is most likely to occur in her cells so that glycolysis can continue to produce ATP?
a) cellular respiration
b) alcohol synthesis
c) lactic acid fermentation
d) alcohol fermentation
Answers
Answer:
C is the correct option.
Explanation:
Cells in the body continue to produce ATP in absence of oxygen.
Lactic acid fermentation is most likely to occur in the swimmer's cells so that the process of glycolysis can continue to produce ATP. Thus, the correct option is C.
What is Lactic acid fermentation?
Lactic acid fermentation is a metabolic process in which glucose or other six-carbon sugars are converted into cellular energy (ATP) and the metabolite lactic acid. It is an anaerobic fermentation reaction which occurs in some bacteria and animal cells, such as muscle cells and in absence of oxygen molecule.
Lactic acid fermentation happens in the skeletal muscles. In this process, pyruvate is converted to lactic acid by the lactate dehydrogenase enzyme when oxygen is inadequate. Fatigue is brought on by the formation of lactic acid which buildup in the muscles.
Therefore, the correct option is C.

in a typical animal, mitosis produces _________, while meiosis produces____________.
Answers
In a typical animal, mitosis produces two identical daughter cells, while meiosis produces four unique daughter cells.
Meiosis is a type of cell division that involves the parent chromosome being halved and then divided again to form four unique daughter cells which have only one copy of chromosome from the parent.
This process occurs in sex cells such as the sperm and egg cells.
Mitosis is also a type of cell division but occurs with the parent cells to form two identical daughter cells.
This type of cell division have produces the same number of chromosomes the parents have and occurs in cells of the body which undergoes growth or during replacement of worn-out tissues.

What was the Court’s decision in United States v. Nixon (1974) and how did the decision uphold the idea that even the President of the United States is not above the nation’s laws?
Answers
Answer:
The Supreme Court decided that the President was required to turn over tape recordings and other materials that had been subpoenaed by special prosecutor Leon Jaworski.
In trying to withhold some materials related to the Watergate investigation, Nixon's lawyer had argued that the President of the United States "is not subject to the processes of any court in the land except the court of impeachment." The Supreme Court disagreed, in unanimous fashion. They held that the President could not use executive privilege as an excuse for hiding wrongdoing or avoiding prosecution. In an interview some years after his resignation, Nixon still held to his view, claiming that when the President does something, "that means that it is not illegal." He felt that being in the position of President put him above the law. But the Supreme Court had firmly disagreed. They rejected the idea of "absolute, unqualified Presidential privilege of immunity from judicial process under all circumstances." Executive privilege can only protect matters of military or diplomatic confidentiality

Explanation:
What is Cellular Respiration?
Cellular Respiration is the process in which the cells of living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. The overall chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (stored in ATP)
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals.
Q: How is cellular respiration related to breathing?
A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body. Oxygen needed for cellular respiration is brought into the body with each inhalation. Carbon dioxide and water vapor produced by cellular respiration are released from the body with each exhalation.
Energy Changes in Cellular Respiration
The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Some of this energy is converted to heat. The rest of the energy is used to form many small molecules of a compound called adenosine triphosphate, or ATP. ATP molecules contain just the right amount of stored chemical energy to power biochemical reactions inside cells.

during which checkpoint would damaged or improperly replicated dna halt progression through the cell cycle?
Answers
Answer:
G2/Growth 2 phase
Answer:
When a cell's DNA is damaged, a sensor protein activates p53, which halts the cell cycle at the G 1start subscript, 1, end subscript checkpoint by triggering production of a cell-cycle inhibitor. This pause buys time for DNA repair, which also depends on p53, whose second job is to activate DNA repair enzymes.
If a cell crossed over one time during Prophase I of Meiosis, how
many genetically distinct gametes would be produced?
Answers
Answer:
If crossing over doesn’t occur, then 2 out of the 4 daughter cells would be identical.
We have 46 chromosomes and are diploid meaning we got 1 set (23 chromosomes) from our mom and 1 set (23 chromosomes) from our dad.
In prophase 1, homologous chromosomes associate (chromosome #1 from dad and chromosome #1 from mom. They both code for the same things, but they are NOT identical)
Let’s compare mitosis to meiosis
On the left, see how in mitosis all chromosomes (even homologous) line up in single file (imagine all 46 lining up individually). When anaphase splits the sister chromatids (which are identical) in mitosis, each daughter cell gets the exact same genetic info.
(they get both homologous chromosomes: 1 from dad (yellow)and 1 from mom (purple) resulting in a full diploid set)
On the right in meiosis, see how the homologous chromosomes associate and will split? Chromosome #1 from mom (purple) is going to the left daughter cell while chromosome #1 from dad (yellow) is going to the right daughter cell. This means the two daughter cells will only have 1 set for chromosome #1 (either moms or dads but NOT both) and become haploid (1 set of 23 chromosomes)
Again in mitosis, all 46 lined up individually, but in meiosis the 23 from mom and 23 from dad first associate and each orient to decide which daughter cell gets the dads chromosome or the moms chromosome. They assort independently meaning just because dads chromosome #1 went to the left DOESN’T mean that dads chromosome #2 or #3 will go to the left. This gives a unique pattern of 23 chromosomes for the 2 daughter cells of meiosis 1 (a various mixture of moms and dads, but it is possible to result in a daughter cell with just moms and just dads set, though this would be a very small probability like 1 in 2^23 )
So each daughter cell of meiosis 1 is a haploid set (only 1 set instead of 2) and the opposite of the other (since 1 has fathers while the other has mothers for the same chromosome)
Meiosis 2 is just like mitosis. Here the sister chromatids separate producing 2 identical daughter cells
(identical if crossing over doesn’t occur. Crossing over only occurs on adjacent homologous chromatids)
If crossing over doesn’t occur then both sister chromatids are identical so that 2 out of 4 daughter cells will be exactly identical haploid sets. The other 2 are identical to each other as well.

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

1. tRNA brings the correct amino acid specified by the mRNA codon
3. Amino acids are bonded together to make a polypeptide (protein)
5. The ribosome releases both the mRNA molecule and the polypeptide (protein)
During protein synthesis, all the machinery for synthesis occurs in a sequential manner and the first need is a DNA template, so the correct option is a.
What events occur during protein synthesis?Protein synthesis occurs in the ribosomal machinery and the process is called translation and starts after transcription.
DNA acts as a template for transcription and makes mRNA which translates into protein. mRNA act as a messenger for protein synthesis, this mRNA converts into protein with the help of ribosomal machinery.
In the process tRNA act as an adapter molecule adding an amino acid to the protein chain according to the codon on mRNA. In the last step protein and mRNA are released by the ribosome.
Therefore protein synthesis starts with DNA, hence option a is correct.
