Answer:
The correct answer is that the spliceosome is non-functional.
Explanation:
A spliceosome refers to a composite and large molecular apparatus found mainly inside the nucleus of the eukaryotic cells. The prime function of the spliceosome is to remove the introns from a transcribed pre-mRNA, that is, a kind of primary transcript.
In case if the spliceosome machinery gets failed to function, the mRNA will not remove the introns, that is, the non-coding parts and retains it. This will eventually lead to the formation of longer mRNAs.
The correct option is this: The forelimbs (or possibly hind limbs) will be used for the new purpose of flight. This new function will arise through many gradual steps, and there will be aspects of the wing that reflect its history and are not perfectly suited for flight.
Adaptation refers to the physical or behavioral traits that an organism develop in order to enhance its suitability to its environment. Evolution on the other hand is always brought about by natural selection; organisms that are well adapted to their environments are naturally selected to survive, reproduce and pass their beneficial traits to their offspring. This is a gradual process that occurs over a long period of time.
For wings to develop in a four limbed organism, the organism has to start using the hind or the fore limbs for flight (New adaptive behavior). The genes that support this new behavior will be passed to its offspring and subsequent generations over a long period of time, until the wings are perfectly suited for flight.
Infiltration is the downward movement of water into the soil and runoff is when water flows above the surface of the soil

The people that interfere with cytokinesis in the cells of dividing animals are gene mutations that encode actin.
<h3>How does cytokinesis occur in animal cells?</h3>
Cytokinesis occurs in anaphase in animal cells and prophase in plant cells, then ends in telophase (both in animals and plants). Cytokinesis is the division of the nucleus into two equal parts, each of which contains an identical set of diploid chromosomes to the parent cell.
Cytokinesis in animal cells begins with a groove that occurs right on the cell surface in the equatorial region. On the surface of the cell, there is a contractile ring formed by contracting actin and myosin microfilaments
