Fertilization and formation of the zygote occur Within the body of mosquito.
Zygote, from the Ancient Greek (zygtós), "attached, yoked," from (zygoun), "to join, to yoke," A fertilization between two gametes produces a eukaryotic cell. The genome of a zygote, which consists of the DNA from each gamete, is what makes up a new individual creature and holds all of its genetic material.
The zygote is the first developmental stage in animals with many cells. When an egg cell and sperm cell unite to produce a new, distinct organism, a zygote is created in humans and the majority of other anisogamous species. With the aid of mitosis, the zygote can divide asexually in single-celled organisms to create identical progeny. The chloroplast DNA (cpDNA) of a Chlamydomonas zygote is inherited uniparentally from the parent with the mt+ mating type; as a result, such cells are typically uncommon. The mapping of chloroplast genetics through recombination was made possible by these uncommon biparental zygotes.

<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops

The last Caribbean monk seal that died was the last member of a SPECIE.
All the living things, both plants and animals are placed in a hierarchical order depend on their characteristics and specie is the least stage on that rank. A specie refers to a specific group of animals which share similar physical characteristics. The Caribbean monk seal for instance is one of the specie of fishes that exist on earth.Thus, a specie is a basic unit of classification which recognize animals of the same sort.<span />
