Answer: The main purposes of mitosis are  Organism growth and tissue repair and maintenance.

Explanation: MITOSIS is the step of cell division in cell cycle. Cell cycle contains G1 S G2 and M phase. During mitosis  a cell replicates its chromosome and segregates them to produce two identical daughter nuclei, which after undergoing cytokinesis produces two identical daughter cells. mitosis is often called as equational division.

Mitosis do not control metabolism nor it synthesize energy.

MITOSIS produces two identical daughter cells which are identical to their parents, so it cannot cause genetic diversity.

mitosis helps organism to grow in size and tissue repair and maintenance by producing new cells identical to each other.

gametes are not produced by mitosis they are produced by meiosis that is reductional division.

Answer:   Differences in mRNA splicing.

Explanation:

The exon is the region of a gene that is not separated during the cutting and splicing process and thus remains in the mature messenger RNA. In genes encoding a protein, it is the exons which contain the information to produce the protein encoded in the gene. In these cases, each exon encodes a specific portion of the complete protein, so that the set of exons forms the coding region of the gene. In eukaryotes, the exons of a gene are separated by long regions of DNA (called introns) which do not code.

RNA splicing is a post-transcriptional process of maturing RNA from which certain sequential fragments are removed. This process is very common in eukaryotes, and can occur in any type of RNA, although it is more common in mRNA. It consists of removing the introns from the primary transcript and then binding the exons. Particularly, alternative RNA splicing takes place when one gene can produce different proteins as a result of what segments are considered as introns and exons. When different segments are considered exons, the result is a great diversity of mature transcripts which produce different proteins.

So, gene splicing is a post-transcriptional modification in which a gene can code for many proteins, which makes it an important source of protein diversity.

Explanation:

The molecules in the given image are transported down the concentration gradient. Thus, the correct option is C.

There are two ways by which molecules are transported across a membrane which are active transport and passive transport.

Diffusion is a type of passive transport, that is, it does not involve the expenditure of energy.

In diffusion, the transport of molecules across the membrane occurs from a region of high concentration to a region of low concentration, that is, transport occurs down the concentration gradient.

Thus, the molecules in the picture are transported through diffusion, that is down the concentration gradient. Thu,the correct option is C.

A thermos keeps cold things cold in the same way. It doesn't contain some kind of cooling device. The same vacuum that keeps hot things hot keeps cold things cold. Heat that might otherwise transfer to the cold contents of the thermos is prevented from reaching it because of the vacuum between the thermos walls.

Today's thermoses are constructed much more sturdily than those in the past. The first thermoses featured metal exteriors with glass interior walls. These thermoses often ended up getting broken when accidentally dropped.

Collagen is produced in the human body until natural aging occurs, whereas elastin is mainly produced during the fetal period. Collagen has the main property of providing structures with strength, whereas elastin will allow the structures which contain it to stretch and return to their initial form without damage

From what I know,  collagen/elastin ratio as well as the collagen and elastin structures change with age [3,4,5,6]. The elasticity of the skin increases with atrophy of the collagen fiber bundles, the related flattening of the rete ridges, and the thickening of the dermal elastic fiber.

Osmosis is the diffusion of water molecules across a selectively permeable membrane. This process does not require the cell to use energy to move molecules. It is an example of passive transport.

Diffusion may be defined as the movement of solutes from the region of higher concentration to a region of lower concentration.

Osmosis may be defined as the spontaneous movement of water molecules from the region of higher concentration to a region of lower concentration through a semipermeable membrane.

Therefore, it is well described above.

The generation time of the bacteria in the following culture is approximately 3.01  hours.

To determine the generation time of bacteria, we can use the formula:

Generation time (t) = (Time elapsed (T) / Number of generations (n))

In this case, we have a time difference of 10 hours between the two samples.

To calculate the number of generations, we can use the formula:

Number of generations (n) = log(N₂ / N₁) / log(2)

Where N₂ is the final cell count (10,000 cells/ml) and N₁ is the initial cell count (1,000 cells/ml).

Plugging in the values, we get:

Number of generations (n) = log(10,000 / 1,000) / log(2) ≈ 3.32

Now, we can calculate the generation time:

Generation time (t) = Time elapsed (T) / Number of generations (n)

Generation time (t) = 10 hours / 3.32 ≈ 3.01 hours

Therefore, the generation time of the bacteria in this culture is approximately 3.01 hours.

The resting phase of the cell cycle is called interphase.

Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.

This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.

Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.

Hearing involves a process of sound wave transduction through the tympanic membrane and ossicles. If the tympanic membrane (E) loses its flexibility, sound quality may diminish. The Eustachian tube and cochlea serve to manage pressure within the ear.

The process of hearing (audition) involves the transduction of sound waves into a neural signal. When the tympanic membrane (structure E in your diagram), or eardrum, is struck by sound waves, it vibrates. These vibrations are then transferred to the ossicles, which are three small bones in the middle ear. The ossicles are identified as structures A (Malleus or Hammer) and B (Incus or Anvil) in your diagram. Sound waves are finally transduced into a neural signal in the inner ear.

If the tympanic membrane was to lose its flexibility, it would not vibrate as effectively when struck by sound waves. This could diminish the quality of sound and potentially lead to hearing loss.

The Eustachian tube equilibrates air pressure on both sides of the tympanic membrane. This would be your answer to part (a) of the lettered question. Part (b) refers to the role of the cochlea in the inner ear, which helps to absorb excess pressure waves from the inner ear.
