In a process called <u>Synapsis</u>, paired homologous chromosomes align randomly at the cell equator. This occurs during stage <u>prophase I</u> of cell division.

Synapsis refers to the pairing of the homologous chromosomes in the meiosis occuring in the reproductive cells. Meiosis I is divided into four phases called the prophase I, metaphase I, anaphase I and the telophase I. Prophase I is the longest phase of meiosis which is further divided into leptotene, zygotene, pachytene, diplotene and diakinesis.

During the zygotene of meiosis I, the paring of the homologous chromosomes called the synapsis takesplace which is facilitated by the protein structure called the synaptonemal complex. The paired chromosomes are called the bivalents. This facilitates the homologous recombination.

It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region.

Harrizon [31]

It takes seven seconds for the pupil to adapt once again to dark conditions after getting exposed to headlight glare.

The pupil of the eye refers to the black circle at the midpoint of the iris. The pupil functions mainly to monitor the amount of light getting inside the eyes, to make sure that to much light does not blanch out the visions in extremely bright light conditions, and to capture as much light as possible in dim light conditions.
