Which is required for both anaerobic respiration and aerobic respiration?
oxygen
O water
O mitochondria
O glucose
Answers
Answer: Glucose
Explanation: Substrate is always required. Glucose is the substrate. Anaerobic respiration in absence of o2 and aerobic in presence of o2.
Aerobic respiration totally converts glucose into carbon dioxide and water, whereas anaerobic respiration only fully converts glucose into lactic acid or alcohol (alcohol fermentation) (lactic acid fermentation). Thus, option D is correct.
What similarity in anaerobic and aerobic respiration?The fact that glucose is used as the first molecule in both aerobic and anaerobic respiration is one of their similarities.
Additionally, both aerobic and anaerobic respiration result in the production of ATP, but aerobic respiration generates far more ATP than anaerobic respiration.
For a modest output of ATP, glucose is partially broken down in the cytosol during anaerobic respiration.
For a higher yield of ATP, aerobic respiration uses oxygen to completely break down glucose in the mitochondria.
Therefore, glucose is required for both anaerobic respiration and aerobic respiration.

Chicken liver is placed into lemon juice for 10 minutes. What type of evidence of a chemical reaction would be expected to occur when H2O2 (hydrogen peroxide) were added?
A) a lot of bubbles within a few seconds
B) some bubbles within the first minute
C) very few to no bubbles
D) the liver will catch fire, explote and cause the school to evacuate.
Answers
Answer:
When hydrogen peroxide is added to a chicken liver sample exposed to lemon juice the chemical reaction will be slower and appear some bubbles within the first minute (option B).
Explanation:
The liver contains an enzyme called catalase, whose function is the degradation of hydrogen peroxide (H₂O₂), an intense reaction that produces gas and heat. The activity of this enzyme must occur at an appropriate pH, so changes in pH can affect the activity of catalase.
Under normal conditions, when a liver sample is exposed to H₂O₂, bubbles and foam appear in the sample as a result of the catalase reaction. When the chicken liver sample is subjected to the acidic lemon juice, the reaction will occur, but more slowly.This is because the activity of the catalase enzyme, present in the liver, continues to occur —although it decreases— and will form few bubbles over a longer period of time.
The other options are not correct because:
A. At a lower pH, the reaction will not form many bubbles.
C. Even if the reaction is minor, and produces very few enzymes, it will always occur.
D. Although the catalase/H2O2 reaction produces heat, it is impossible for the liver to catch fire and cause evacuation from the school, even less so with a reaction whose speed has been slowed down.

how do telophase i and telophase ii differ during meiosis in animal cells?
Answers
When telophase I ends, cells are still diploid; when telophase II ends, cells are haploid. Whereas telophase I is when daughter cells divide by forming a cell plate, telophase II is when cytokinesis occurs.
The last phase of each meiosis, telophase 1 for meiosis 1 and telophase 2 for meiosis 2, is known as telophase. Homologous chromosomes are separated from one another during telophase 1, whereas sister chromatids are split apart at the centromere during telophase 2.
This is the primary distinction between telophases 1 and 2. In plant cells, the telophase occurs when the cell plate forms, allowing the two daughter cells to be separated. There is pinching of the cell membrane in animal cells.

What is a common ancestor of the monarch butterfly?

PLEASE HELP I HAVE BEEN TRYING TO FIGURE THIS OUT A certain plant can have two flower color options: yellow or orange. A geneticist is looking to create a true-breeding yellow folowered plant. When he self pollinates the plant he believes to be true-breeding it results in 50% yellow folwered offspring and 50% orange flowered offspring. Do these results support or refute his belief that his plant is true breeding? Why or why not?
Answers
True-breeding plants are those that produce offspring with the same traits as the parent plant when they self-pollinate or are cross-pollinated with another true-breeding plant with the same traits. If the geneticist's yellow flowered plant was true-breeding, all of its offspring should also have yellow flowers.
However, the geneticist's self-pollination experiment resulted in offspring with both yellow and orange flowers, indicating that the yellow flowered parent plant was not true-breeding. If the parent plant was heterozygous for flower color (i.e. carried one dominant and one recessive allele), the observed 1:1 ratio of yellow and orange flowered offspring would be expected. This suggests that the parent plant was not true-breeding and instead carried a dominant allele for yellow flowers and a recessive allele for orange flowers.
Therefore, the results of the experiment refute the geneticist's belief that his plant is true-breeding, and suggest that the plant is heterozygous for flower color.
Correctly pair each of the temperatures used in the PCR reaction, with what occurs at that temperature. The temperatures given are

And the answer choices to match with these temps are
allow primers to anneal to the template
B. separate template DNA into single strands
C. allow DNA polymerase to build complementary DNA
Answers
The temperature of 94-98 Cº is used to separate the template DNA into single strands, which is necessary for the PCR reaction to occur. The temperature of 65-72 Cº is used to allow primers to anneal to the template, which is a critical step in the PCR reaction as it provides the starting point for DNA polymerase to build complementary DNA.
Finally, the temperature of 55-70 Cº is used to allow DNA polymerase to build complementary DNA, which is the key step in the PCR reaction that amplifies the target DNA sequence.
The analysis of ancient DNA samples and the detection of infectious organisms are only two examples of the many genetic testing and research techniques that heavily rely on PCR. Extremely small amounts of DNA sequence copies are exponentially amplified by PCR in a series of temperature-changing cycles. For a wide range of applications in medical laboratory research, including biomedical research and criminal investigations, PCR is now a standard and frequently crucial technology.

Transcription is the synthesis of RNA under the direction of DNA while translation is the process whereby a strand of mRNA directs assembly of amino acids into proteins within a ribosome.
Messenger RNA (mRNA) is the RNA that encodes and carries information from DNA during transcription to sites of protein synthesis to undergo translation in order to yield a protein.
Transfer RNA (tRNA) is the short-chain version of RNA that transfers individual amino acids to ribosomes during protein synthesis.
The transfer RNA is similar to the template DNA, with the difference being that Thymine (T) base is changed to Uracil (U).

The whole process of protein synthesis involves transcription -mRNA synthesis- and translation -protein building-. In the exposed examples, Amino Acids: ILE - ALA - ILE - ARG - LEU - GLN - STOP. Amino Acids: ILE - PHE - LYS - PRO - GLY - STOP.
What are transcription and translation?
Transcription and translation are two processes involved in protein synthesis.
Transcription is mRNA synthesis. It occurs in the nucleus and copies -transcribes- a fragment of the DNA template strand to carry genetic information to the cytoplasm. This information is necessary to build a protein.
During transcription, mRNA complements DNA base sequences. Nucleotides are added to the growing molecule in a way that
adenine pairs uracyl (not thymine), thymine pairs adenine, guanine pairs cytosine, and cytosine pairs guanine.Once mRNA synthesis is completed, the molecule leaves the nucleus toward the cytoplasm where protein synthesis occurs.
Translation occurs in the cytoplasm and is the process through which rRNA and tRNA read the genetic information in mRNA and build the protein by following the mRNA codon sequences and adding the correct amino acids.
While rRNA moves along mRNA, the associated tRNA recognizes mRNA codons and adds the amino acid to the chain.
In the exposed example,
DNA Template TAG CGT TAT GCC AAC GTC ATT
mRNA AUC GCA AUA CGG UUG CAG UAA
tRNA UAG CGU UAU GCC AAC GUC AUU
Amino Acid ILE ALA ILE ARG LEU GLN STOP
DNA Template TAG AAA TTT GGG CCC ATC
mRNA AUC UUU AAA CCC GGG UAG
tRNA UAG AAA UUU GGG CCC AUC
Amino Acid ILE PHE LYS PRO GLY STOP
