direction
The mRNA molecule is complementary to its DNA template, which depends on the gene being
transcribed.
O The mRNA molecule is identical to its DNA template, which depends on the gene being transcribed.
Answers
Answer:
The mRNA molecule is complementary to its DNA template, which depends on the gene being transcribed.
Explanation:
The process of the formation of RNA from DNA is called transcription.
Messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to its DNA template as the enzyme, RNA polymerase matches the complementary bases to the original DNA strand and then initiates the process of RNA synthesis. Once the strand gets completed, the process got terminated.
Hence, the correct answer is "The mRNA molecule is complementary to its DNA template, which depends on the gene being transcribed."

which of the following statements describes a nonsense mutation?
Answers
The nonsense mutation is a point mutation that produces a stop codon when replacing a single base. The resulting protein is shorter than it shuld be.
What are the types of point mutations?
When a change occurs in a single base pair, it is known as a point mutation.
Points mutations might be either silent, missense, or nonsense.
In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes the mRNA codon to be a stop codon, we are referring to a nonsense mutation.Nonsense mutations have the ability to put an end to protein synthesis earlier than they should. The production of a mutated stop codon makes the new protein to be shorter.

What's developed as a result of the electron transport chain?
Answers
Answer:
The electron transport chain (ETC) is a series of protein complexes located in the inner membrane of the mitochondria that transfer electrons from electron donors to electron acceptors via redox reactions. As a result of the ETC, a proton gradient is formed across the inner mitochondrial membrane, which drives ATP synthesis by the enzyme ATP synthase. The ATP produced through oxidative phosphorylation is the primary energy source for most cellular processes.
Explanation:
The electron transport chain (ETC) is the final step of aerobic cellular respiration and is where the majority of ATP is generated. As electrons move through the ETC, they release energy that is used to pump hydrogen ions across the inner mitochondrial membrane, creating an electrochemical gradient. This gradient powers ATP synthase, which generates ATP by adding a phosphate group to ADP. In summary, the electron transport chain results in the production of ATP, which is the primary source of energy for cellular processes.

How many direct and indirect transmission episodes could you expect after all?
A. 1 direct and 3 indirect transmissions
B. 1 direct and 2 indirect transmissions
C. 3 indirect transmissions
D. Unknown number of direct and indirect transmissions
Answers
Answer:
C. 3 indirect transmissions
Explanation:
In epidemiology, direct transmission is considered to occur when an individual has direct contact with a pathogen, which infects him and develops a disease. Indirect infections, on the other hand, occur when individuals come into contact with the pathogen through a transmission vehicle.
In this case, we can conclude that in the question above, there were 3 cases of indirect transmission. This is because all people who had contact with the pathogen, established that contact through the contaminated marker. In this case, the marker is a transmission vehicle.

As arizona poppy plant carries out photosynthesis, which of the following would not occur during stage 1 of the process?
Answers
Answer:
a
Explanation:
As arizona poppy plant carries out photosynthesis, Glucose is created using carbon dioxide. The Arizona poppy is a plant indigenous to the American Southwest.
What is photosynthesis ?Photosynthesis is a process that plants and other organisms used to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis. Water is oxidized within the plant cell, which means it loses electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.
Photosynthesis is the process by which carbon dioxide and water are converted into oxygen and glucose. The plant consumes glucose as food and produces oxygen as a byproduct. Cellular respiration is the process by which oxygen and glucose are converted into water and carbon dioxide.
Thus, As arizona poppy plant carries out photosynthesis, Glucose is created using carbon dioxide.

What did Mendel conclude about patterns of inheritance?Mendel concluded that inheritance is determined by discrete units called genes, which are passed down from parents to offspring in a predictable manner.
He observed that some traits are dominant over others, and that these dominant traits can mask the expression of recessive traits. Mendel also proposed the Law of Segregation, which states that during gamete formation, the two alleles of a gene separate from each other so that each gamete carries only one allele for each gene.

1. padding at a full speed is putting new demands on a Joe's body. what are these new demands and how does the body respond to them?
2. what changes in Joe's muscles promote unloading of oxygen from hemoglobin for use by the muscle cells when paddling?
3. what conflict is produced between Joe's need to keep his body cool and his need to remove his nitrogenous waste from his blood? what did he do before the race to help alleviate this conflict?
4. Joe stopped paddling and his muscles are at rest. why are his heart and breathing rates still so high?
5. why is he sweating more after the race than during the race?
6. what changes have occurred in his blood chemistry since the start of the race?
Answers
Answer:
1. When paddling at full speed, Joe's body demands an increased supply of oxygen to fuel the working muscles. The body responds by increasing the heart rate and breathing rate to deliver more oxygen to the muscles. The body also needs to regulate its temperature, which increases as a result of the energy expended during paddling. This puts a demand on the body to cool down through sweating and increased blood flow to the skin.
2. During paddling, Joe's muscles undergo changes that promote unloading of oxygen from hemoglobin for use by the muscle cells. These changes include an increase in temperature, acidity, and levels of carbon dioxide. These changes cause hemoglobin to release oxygen more readily, allowing the working muscles to extract more oxygen from the blood.
3. Joe's need to keep his body cool conflicts with his need to remove his nitrogenous waste from his blood. Nitrogenous waste, such as urea, is produced by the breakdown of proteins in the muscles and needs to be removed from the blood by the kidneys. Sweating helps to cool the body down but also removes water from the body, which can make it harder for the kidneys to filter nitrogenous waste. Before the race, Joe may have increased his water intake to help alleviate this conflict and ensure proper kidney function.
4. Even when Joe's muscles are at rest, his heart and breathing rates remain high because his body is still working to recover from the intense exercise. The increased heart rate helps to deliver oxygen and nutrients to the muscles, while the increased breathing rate helps to remove carbon dioxide and other waste products from the body.
5. Joe is sweating more after the race than during the race because his body is still trying to cool down and regulate its temperature. The increased sweating helps to remove excess heat from the body, which was generated during the intense exercise.
6. Several changes have occurred in Joe's blood chemistry since the start of the race. These include an increase in levels of lactate and carbon dioxide, which are waste products produced by the muscles during intense exercise. There may also be a decrease in pH levels due to the build-up of acid in the blood. Additionally, Joe's blood glucose levels may have decreased as a result of the energy used during the race.
Explanation:
2. Changes in Joe's muscles promote unloading of oxygen from hemoglobin for use by the muscle cells when paddling. These changes include a decrease in pH due to the production of lactic acid, which causes hemoglobin to release oxygen more readily. Additionally, the increase in temperature of the muscle tissue also promotes the unloading of oxygen from hemoglobin.
3. Joe's need to keep his body cool conflicts with his need to remove his nitrogenous waste from his blood. To help alleviate this conflict before the race, Joe likely hydrated himself and wore lightweight, breathable clothing to help regulate his body temperature. During the race, Joe may have also used a cooling towel or other methods to help keep his body cool.
4. Joe's heart and breathing rates are still high after stopping paddling because his body is still working to remove waste products such as lactic acid from his muscles. Additionally, the body is still working to restore oxygen levels to normal and to remove excess heat generated by the muscles during the exercise.
5. Joe is sweating more after the race than during the race because his body is still working to remove excess heat generated by the muscles during the exercise. Additionally, the body continues to produce sweat after exercise to help regulate body temperature and remove waste products.
6. Several changes have occurred in Joe's blood chemistry since the start of the race, including a decrease in pH due to the production of lactic acid, an increase in carbon dioxide due to increased respiration, and a decrease in oxygen levels due to increased use by the muscles. Additionally, Joe's body may be producing more red blood cells to help transport oxygen to the muscles more efficiently.
