Answer:
D. Aids
Explanation:
Aids is one of the most deadliest diseases in the world. When you contract aids, it's designed to infect the cells that try to destroy it, it's a whole zombie apocalypse in your body and you don't even know it.
It attacks and weakens the immune system, and our immune system defends our bodies against infections, but HIV is extremely strong and it over powers the system, I'm not sure if there's an immune system strong enough to fight HIV or aids.

<span>The
answer is color. The colors range from
red, blue and green. Visible light is
composed of Red Orange Yellow Green Blue Indigo Violet light colors which are
visible on a rainbow. It is only by diffraction of white light that these colors can be perceived because
they have different wavelengths.</span>
Answer:
The three muscle layers in the stomach's mascularis externa.
Explanation:
The stomach has four layers in their wall; The mucosa which is the inner lining of the stomach that secretes hydrochloric acid. The submucosa made of connective tissues, nerve fibres and blood vessels. The mascularis externa, made of 3 muscle layers responsible for contraction and parastalsis. The outer fibrous membrane or layer called serose.
The muscularis externa in the stomach is unique in that it has three muscle layers compared to the rest of the gastrointestinal tract. This is because the stomach has to work extra hard in mechanically breaking down chunks of food into smaller pieces during digestion.
An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. F1 hybrids are used in genetics, and in selective breeding, where it may appear as F1 crossbreed. In other words, The filial generation comprised of offspring(s) resulting from a cross between two individuals from parental generation. In genetics, a test cross is a cross involving two individuals in order to determine zygosity (i.e. the degree of similarity of the alleles for a trait in an organism). For instance, a test cross is done between an organism exhibiting the dominant trait and another organism displaying the recessive trait. The first set of parents in a test cross is referred to as the parental generation (or P-generation). The offspring resulting from a parental cross are referred to as the first filial generation (or F1 generation). The F1 generation is the generation resulting immediately from a cross of the first set of parents (parental generation).
A particular example is a cross between two garden pea plants, i.e. one plant producing purple flowers and another plant producing white flowers as performed by Gregor Mendel (the Father of Genetics). These two plants comprise the parental generation (P generation) and the first hybrid offspring from the parental cross comprise the first filial generation. In Gregor Mendel's test cross, the F1 offspring produce purple flowers. When the F1 hybrids were allowed to self-pollinate, the offspring resulted in plants producing either purple or white flowers. The offspring from the F1 generation comprise the second filial generation or F2 generation.
