The epidermis protects deeper tissues from solar radiation through the action of melanocytes.
Melanocytes are specialized skin cells situated in certain parts of the body such as the lower layer of the skin's epidermis, the inner ear, the middle layer of the eye, heart, and bones. Melanocytes are responsible for the production of the protective skin-darkening pigment known as melanin that determines the skin’s colour. Melanin mainly functions as protection against solar radiation. It also play a role in the immune system.
Answer:
Option-C
Explanation:
In gymnosperms, the embryo is formed after the fertilization needs nutrition. The nutrition in the gymnosperms is provided by the female gametophyte cells as these cells degrade to provide the nutrients. Since the female gametophyte is haploid in nature, therefore, is the correct answer.
The seed is formed after the fertilization has occurred therefore is considered the diploid structure. The outer structure which helps in the dispersal of the cell thus is considered the diploid structure.
Thus, Option-C is correct.
Oh I love this question. "MRSA" or "Mithicillin resistant staphylococcus aeues" is bacterial infection.
MRSA is unique to bacteria for it's ability to replicate and maintain homeostasis even when an antibiotic in introduces to destroy it. This resistance can have dangerous consequences usually mainly due to the requirement of needing aggressive in hospital treatment, its tendency to spread fast, and its ability to hit you so hard you could go into Sepsis. Its additionally dangerous because it's prevalent in the hospital.
While many people like to blame doctores for, "over prescribing" of antibiotics the fault doesn't't rest with a provider. In regards to evolution when a person is sick with a a common staphy infection people are prescribed antibiotic. The patient is required and usually specifically told to take the full course. The reason why is because the bacteria that would cause MRSA would still not have developed but are still alive following a treatment... However they gain the ability to become antibiotic resistant if the full course of antibiotics are not followed to a "T".
