Answer:
Cell copies its genetic material during the S-phase of the interphase during cell cycle.
Explanation:
- Cell cycle is broadly divided into two phases ; the interphase and the M-phase.
- M-phase is the dividing phase during which the karyokinesis and cytokinesis takes place.
- Interphase is the phase during which the cell prepares itself for division.
- It is further divided into G1, S and G2 phase.
- During G1 phase the cell prepares for DNA replication and the replication complexes assemble.
- The next phase is S-phase during which the DNA replicates itself and the genetic material in the cell doubles.
- The Next phase is G2 phase during which the DNA is scanned by DNA tepair complexes and errors in the replicated DNA are edited and repaired.
- At the end of G2 phase the cell prepares to enter M-phase.
The front of the eye has an adjustable hole in it called the pupil, covered by a spherical “window” known as the cornea. Light passes through these structures to the lens, a (normally) transparent focusing device controlled by muscles and ligaments. The focused light shines through the fluid-filled interior of the eye to the retina at the back of the eye. The retina contains specialized cells(rods and cones) that react to brightness, darkness and color frequencies, sending this information through the optic nerve to the brain for visual processing...remember that never impulses control the blinking of eye not the release of hormones.
The correction option is A.
Reproductive isolation is divided into two major classes, which are prezygotic and postzygotic isolation. Prezygotic isolation refers to the barriers that are present before the egg can be fertilized while postzygotic isolation refers to those barriers that are present after the egg has been fertilized. Mechanical isolation is a type of prezygotic isolation. Mechanical isolation is a type of reproductive barrier which exist because the male and the female genitalia have different sizes, shapes and locations. The snails that coil to the left and those that coil to the right have the locations of their genitalia in different places.
