The bacterium E.coli is a transgenic organism because human insulin is artificially produced through E. coli by genetically engineered processes. Thus, the correct option is C.
What is Human insulin?Human insulin may be defined as a type of medication that functions as a hormone that controls the excessive level of glucose in the blood. Human insulin is utilized to accept the place of insulin that is naturally produced by the body.
Through a genetically engineered process, the insulin-producing gene is transferred to E. coli with the help of a plasmid vector, and then the human insulin is synthesized in the E. coli which is then extracted and injected into humans.
Therefore, the correct option is C.

The mitochondrial DNA sequence that is shared by two species has a steady mutation rate. Scientists determine the sequences of these two species to be as follows
Species A: CAGGCCATTATG
Species B: CCAGCCTATAGG
Based on this information, which of the following best explains the difference in the DNA sequence between the two species?
A) Species A and B probably share the most recent ancestor because they only differ by three mutations.
B) Species A and B have fewer differences between DNA sequences means that fewer mutations occurred.
C) Species A and B probably have distinct ancestors because they have many differences in mutations.
D) Species A and B are closely related because they differ by five mutations in their DNA sequence.
It is expected that Species A and B have distinct ancestors because they have many differences in mutations (Option C).
What is the mutation rate?The mutation rate makes reference to the number of mutations that appeared in a given nucleotide sequence in a given period of time.
In this case, sequences from Species A and B have 5 mutations and aligned sequences have only 12 nucleotides, which is a considerably high mutation rate to share a common origin.
Nonetheless, information about divergence times might be helpful to determine the origin of these sequences.
In conclusion, nucleotide sequences of Species A and B exhibit many mutations and therefore they do not have the same evolutionary origin (Option C).

what is the difference between an epithelial cell and a cardiomyocyte
The heart is the main pumping organ of the body. The human heart is divided into four chambers two atria and two ventricles. The human heart consists of three layers- epicardium, myocardium, and endocardium.
The middle layer of the heart (myocardium) consists of cardiomyocytes or muscle cells. These cells receive nerve stimulation from the atrioventricular nodes and sinoatrial nodes.
What are Epithelial cells?Epithelial cells form a layer structure which covers most of the surfaces of the body. These cells perform a variety of functions and exhibit different shapes, size and arrangement which makes up different tissues. For example columnar tissues (column-like cells), cuboidal tissues (cube-like cells) and others.

Describe the hearing process
So to put this in a question, I would rephrase it to:
How does hearing work?
It's a little tough to ELI5 without using using the names of the particular organs but here goes:
Sound is nothing more than a wave of air pressure. In other words, it fundamentally involves changing degrees of energy-based air pushing and tugging. Additionally, it is because to this that sound cannot travel in a vacuum. When these waves reach your ear, they first come into contact with the "tympanic membrane," which vibrates and transmits these vibrations to the malleus, incus, and stapes, three small bones (Latin for hammer, anvil, and stirrup).
The waves will subsequently be transmitted via the bones' vibrations to the "cochlea," a spiral-shaped organ filled with fluid. The air pressure wave has so undergone many transformations at this point. Air pressure was followed by mechanical vibrations and is now "fluid pressure." The spiral-shaped cochlea is lined with neurons all the way around. Depending on the fluid pressure waves' intensity, frequency, etc., the cochlea will have to travel a particular distance. Based on these fluid waves, these neurons will then activate, sending information to your brain.
Your brain then decodes these messages to produce the "sound" that you hear. Although I'm not convinced this is the greatest ELI5, this is the main idea.
In essence, your ear works as follows:
Air pressure waves enter the ear, transform into mechanical vibrations, transform into fluid pressure waves, which signal neurons and cause those neurons to fire electrical impulses that communicate with the brain the sound you are hearing.
Cheers,
ROR
Answer:
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
