Upper rocky layer of the Earth that forms the jigsaw of plates that take
part in the movements of plate tectonics. The lithosphere comprises the
crust and a portion of the upper mantle. It is regarded as being rigid
and brittle and moves.
Karyotype refers to the visual appearance and number of the chromosomes in the cell nuclei of a species or an organism. It is known that there are 46 chromosomes in a usual nucleus of a human that comprises 23 pairs of chromosomes. Of these, one pair is considered as sex chromosomes.
In females, the sex chromosomes are XX, while in males, the sex chromosomes are XY. So, the karyotype of a human male would comprise 22 pairs of autosomal chromosomes, an X chromosome, and a Y chromosome.
Answer:
In the apical layer of the pseudostratified ciliated columnar epithelium.
Explanation:
The sustentacular cells work as metabolic and material assistance for the olfactory epithelium. Analogous to neural glial cells, maintaining non-neural cells in the olfactory epithelium that are found in the apical zone of the pseudostratified ciliated columnar epithelium. The olfactory epithelium, located inside the nasal cavity, consists of olfactory receptor cells, which possess functional cilia expansions. The cilia trap odor molecules as they cross beyond the epithelial exterior. Data regarding the molecules are then forwarded from the receptors to the olfactory bulb in the brain. There exist two types of maintaining cells in the olfactory epithelium: sustentacular cells and microvillar cells.
Answer:
4) 4
Explanation: Sexual reproduction is a type of reproduction in which offspring is produced by the mating of male organism with female organism. In sexual reproduction, half genes come from male and other half comes from female organism producing a diploid zygote having double number of chromosomes. So in fruit fly, parents have eight chromosomes so 4 chromosomes comes from each organism.
