Select all the correct answers. Which two examples may be converted into fossil fuel after being buried under pressure for a long period of time?
Answer:
Coal and petroleum.
Explanation:
Coal and petroleum are the two examples that can be converted into fossil fuel after being buried under pressure for a long period of time. Both coal and petroleum formed underground with the presence of very high temperature and pressure. Coal is formed when the plant material is placed under high temperature and pressure for thousand of years while on the other hand, petroleum formed when dead bodies of animals are present underground for a very long time with a suitable pressure and temperature turn into petroleum.
During the respiration of an organism
A, 1 molecule of glucose produces 2
ATP molecules whereas in the
respiration of another organism B, 1
molecule of glucose produces 38 ATP
molecules. Which of the organisms, A
or B has anaerobic mode of
respiration? Explain with reason.
Answer:
The correct answer is - organism A is anaerobic.
Explanation:
Organism A can convert glucose into alcohol, as it undergoes anaerobic respiration, however, there is an incomplete breakdown of glucose. In this process, there are only two molecules of pyruvate formed, and the rest convert to lactic acid or ethanol.
The energy is only enough to release two ATPs. In the aerobic process, there is a complete breakdown of glucose in CO2 and H2O with 38 ATPs.
The correct answer is - organism A is anaerobic.

7. Give two examples of biochemical reactions and explain how an organism uses ATP within the reactions.
Answer:
Because of its energy supply, ATP is necessary for all biological reactions.
ATP is employed both in salt and potassium pumping operations and in the cellular breathing mechanism.
Explanation:
The breakdown of glucose, which frees the cell's energy for life functions, is an example of a catabolic response. Endothermic reactions are called anabolic processes in organisms. The connection between amino acids and a protein is an example of an anabolic response.
If a cell needs energy, this link breaks into adenosine diphosphate (ADP) and a free molecule of phosphate... With an excess power of the cell, this energy is stored by creating ATP from ADP and phosphate. For any muscular contraction, ATP is needed for metabolic reactions.
-To break down one glucose into pyruvate molecules in Glycolysis 2 ATP molecules 4 ATP molecules are produced for a net addition of 2 ATP molecules.
-An inorganic carbon is converted into sugar by ATP in photosynthesis.
A triplet of bases in a template strand of DNA is GAT. What would be the corresponding codon for mRNA?
СТА
CUA
CTU
CUA (This one is wrong)
I don't know why there are two CUAs, but if someone could please help. This is confusing for me. Please explain & no false answers. Thanks much in advance!
Answer:
CUA
Explanation:
Chances are your teacher accidentally put the same option twice and marked one of em incorrect. You infact selected the correct answer because CUA is correct.
DNA has 4 bases: ATGC (Apples on Trees = A - T, & Cows eat Grass = C-G)
RNA has 4 bases: AUGC (RNA lacks the base T so A binds with U instead).
So for template strand GAT, the mRNA made from this codon has complimentary pairing based on RNA so G binds with C, A binds with U, and T binds with A.
A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU
DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) in a sequence.
Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil is substituted for thymine instead. So, in transcription, adenine turns into thymine, and guanine turns into cytosine, and vice-versa.
Thus, A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

the
hypothesis because there was a difference in bird
beak distribution
Answer:
The answer is "supported and when fruit was removed"
Explanation:
It dated the idea from this laboratory because the distribution of avian beaks differed. If any kind of food available keeps shifting, the frequency of the beak types changes as beaks with beaks is far more suitable for food available. The data in this laboratory confirmed the theory, so because the fruit was removed by birds. These results of this laboratory confirm this idea because the dispersion of pigeons when food was taken was varied.

All of the given answer options represent organisms that could coexist in an ocean
ecosystem. In this hypothetical ecosystem, which organism will receive the least amount of
energy in the food pyramid?
Tuna
Great white shark
Seal
Anchovy
Answer:
B. Great white shark
Explanation:
In any food pyramid, the organism at the top of the food pyramid usually gets the least amount of energy in the food pyramid, while those at the bottom have the highest energy in the food pyramid. This is because, as energy moves up the pyramid, some are lost.
In an hypothetical ecosystem, the great white shark will top the food pyramid. Therefore, it would get the least amount of energy in the food pyramid.
Propose what happens to sodium and potassium ions during hyperpolarization.
Answer:
En biología, la hiperpolarización es cualquier cambio en el potencial de membrana de la célula, que hace que esté más polarizada. Es decir, la hiperpolarización es un incremento en el valor absoluto del potencial de membrana de la célula.
During hyperpolarization, sodium ions are pumped out of the cell and potassium ions are pumped into the cell, leading to an overall increase in the negative charge within the cell.
What is hyperpolarization?Hyperpolarization is a process that occurs in cells, particularly in neurons (nerve cells). It is characterized by an increase in the negative charge within the cell, which results from the movement of ions across the cell membrane. During hyperpolarization, sodium ions are pumped out of the cell and potassium ions are pumped into the cell. This results in a more negative charge inside the cell, which can inhibit the cell's ability to respond to stimuli.
Hyperpolarization is the opposite of depolarization, which is a process that leads to a decrease in the negative charge within a cell and an increase in the cell's excitability. Hyperpolarization can be triggered by various stimuli and plays a role in the normal functioning of the nervous system.

If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their
own.
If isolated from a plant cell, a chloroplast can survive and reproduce on its own.
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).

while obtaining the vitals during the seconary assessment, the EMT will assess the respirations. what woul dbe included about the respirations during the primary vitals assessment
Answer:
Rate and tidal volume
Explanation:
Tidal volume is the volume of air moved in or out of the lungs with each normal breath. A normal tidal volume is around 500 to 600 mL per inspiration and/or 6 to 7 mL per kilogram of body mass. An Emergency Medical Technician (EMT) should assess the respiratory rate (as well as rhythm and quality), having into account that a normal respiratory rate in an adult is 12 to 18 breaths per minute (BPM). Moreover, an appropriate tidal volume is also fundamental in assisting individuals in respiratory distress and arrest.
