Answer:
Innate immunity is a nonspecific defense mechanisms that play its role as soon as an antigen appear in the body (it is relatively rapid but nonspecific and because of that it is not always effective)
Explanation:
The barries of innate immunity are:
Skin: At Epidermal surface, its protective aspect are keratinized cells that lives on the surface, known as Langerhans cells.
Skin sweat or secretions: Their specific defense is sweat glands and sebaceous glands, and their protective aspect is low ph and washing action.
Mucosal surfaces: they are at the mucosal epithelium, and their protect aspects are nonkeratinized epithelial cells.
Oral cavity: They defend salivary glands through Lysozyme
Explanation:
If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
You do:
R R
R
r
Your offspring would be: RR, RR, Rr, Rr
So, about 50% of the offspring will have red flowers
Your answer is
50%
