Answer:
5. under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
Explanation:
The contraction of muscles occurs in the presence of Adenosine Triphosphate (ATP) because ATP supplies the muscles with the energy they require for contraction.
Muscles can undergo contraction Aerobically ( in the presence of oxygen) or Anaerobically ( in the absence of oxygen).
When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
The branch of science which deals with a living being is called biology.
The correct answer is E.
The process of breakdown of the glucose molecule into pyruvic acid is called glycolysis. The process of glycolysis is done under the aerobic reaction. The reaction which took place in presence of air is called aerobic reaction.
In this process, Glucose is completely digested into carbon dioxide, water, and energy. Hence, the lactic acid is not formed.
The lactic acid is formed due to a lack of oxygen and leads to incomplete oxidation.
Hence, the correct answer is E that is under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.

What evidence is there that every organism on earth once had a common ancestor
There is a tonne of evidence that points to a common ancestor for all living things on Earth. Numerous sources, including as genetic, morphological, and fossil data, contribute to this proof. First, the genomic data points to a common ancestor for all living things on Earth.
What is the depiction regarding the DNA ?DNA is a component of all living things, and all living things' DNA is made up of the same four nucleotide bases: adenine, guanine, cytosine, and thymine.
The same genetic code, which is a collection of instructions that governs how the data in DNA is utilised to make proteins, is also used by all living things. This shows that all living things had a common ancestor who had the same four nucleotide bases and genetic code.
Second, the data from morphology implies believe there is a single ancestor for all living things on Earth. There are some traits that all species have, such a cell membrane and a nucleus.
Additionally, the same fundamental building ingredients found in proteins, carbohydrates, and lipids make up every single life. This argues that all living things descended from an ancestor who had the same fundamental traits and building components.
Last but not least, fossil evidence points to a common progenitor for all living things on Earth. Direct proof of an organism's evolutionary history can be found in fossils. Scientists have been able to track the evolutionary history of creatures by analysing the fossil record, and they have found that all organisms have developed from a common ancestor. Consequently, there is a lot of data that supports the evidences.

Whereas superficial flexors in the anterior compartment of the forearm originate from the _____ epicondyle of the humerus, the superficial extensors in the posterior compartment of the forearm originate from the _____ epicondyle of the humerus.
Answer:
Whereas superficial flexors in the anterior compartment of the forearm originate from the medial epicondyle of the humerus, the superficial extensors in the posterior compartment of the forearm originate from the lateral epicondyle of the humerus.
Explanation:
The forearm has 2 compartments: an anterior compartment responsible for the flexion of the wrist, and a posterior compartment with the function to extend the wrist.
The superficial muscles in the anterior compartment arise from the common flexor tendon that originates from the medial epicondyle of the humerus. This compartment is mostly innervated by the median nerve.
The superficial muscles in the posterior compartment originate from the lateral epicondyle of the humerus and are innervated by the radial nerve.
The ulnar nerve innervates the flexor carpi ulnaris and flexor digitorum profundus in the forearm.
in which replication cycle is the viral genome reproduced without damage to the host cell
Answer:
lysogenic cycle
Explanation:
it allows a phage to reproduce without killing its host. Some phages can only use the lytic cycle, but the phage we are following, lambda ( λ), can switch between the two cycles.
The viral genome can be reproduced without harming the host cell during the lysogenic cycle. Here the viral genome becomes part of the host's DNA, and is replicated without causing cell death.
Explanation:The viral replication cycle in which the viral genome is reproduced without causing damage to the host cell is known as the lysogenic cycle. In this cycle, the viral genome is incorporated into the host DNA and is replicated along with the host cell’s DNA without causing cell death. This is in contrast to the lytic cycle where the virus destroys the host cell to release new virus particles. The lysogenic cycle allows the virus to lay dormant within the host cell, potentially for many years.

What must this cell do before it can carry out mitosis? (The cell has a diploid number of 444 chromosomes; 2n = 42n=42, n, equals, 4)
Answer:
grow its cell contents, double its DNA and synthesize proteins
Explanation:
Before a cell can carry out mitosis, such cell will need to grow and develop its contents, synthesize (double) DNA, and also synthesize proteins.
Mitosis involves the equational division of non-sex cells to give two daughter cells. Hence, the contents of a cell that wants to divide by mitosis must be enough to be shared by the two daughter cells.
This is why a cell that will divide by mitosis has to go through the G1 phase, the S phase and the G2 phase where the content of the cells grow and develops, DNA of the cell is replicated, and protein is synthesized respectively. All these processes take place during the interpphase stage of the cell cycle.
Final answer:
Before mitosis, a cell with a diploid number of 4 must replicate its DNA during interphase to ensure each daughter cell receives an identical set of chromosomes.
Explanation:
Before a cell can carry out mitosis, it must first undergo interphase, specifically the S phase (synthesis phase), where the cell replicates its DNA. During interphase, the cell's chromosomes are dispersed as structures in the nucleus and must be duplicated to ensure that each of the two resulting daughter cells receives an identical set of chromosomes. The process of DNA replication is crucial because chromosomes contain genes, which must be accurately distributed to maintain the organism's genetic information. Therefore, when an animal cell with a diploid number of four (2n = 4) undergoes mitosis, it produces two diploid daughter cells each with four chromosomes.

Explanation:
Rudolf Virchow while building on the work of Theodore Schwann formulated a part of the cell theory which opined that cells arose from pre-exsiting cells which disproved the theory of spontaneous generation
Although this assertion has earlier been made by another scientist, Robert Remak in 1852, Schwann did not accept until later until after series of investigations. Schwann was later accused of publishing the work of Robert Remak as his in 1855.
