Answer: The color of the iris is the example of polygenic inheritance.
Explanation:
Polygenic inheritance can be defined as the inheritance in which one trait is controlled by the two or more than two genes. The color of the skin, color of iris, weight and height are polygenic traits. The color of the iris is the polygenic trait the number of genes responsible for this are unknown but these genes are responsible for the synthesis of melanin pigment imparting color to the iris. OCA2 and HERC2 are the chief genes present on chromosome 15 responsible for this trait. Dark brown and black eyes are expected to have more amount of melanin as compared to the green and hazel eyes.
Micafungin is one of the antifungal drugs that act by inhibiting the biosynthesis of essential components of the fungal cell wall, which interferes with growth and reproduction.
A compound from the newly discovered class of antifungal drugs called echinocandins that prevent the synthesis of cell walls. Echinocandins prevent the production of 1,3-D-glucan, a crucial element of the fungal cell wall that is absent in mammalian cells. Micafungin injections are used to aid the body in fighting off serious fungus infections like candidemia, acute disseminated candidiasis, candida peritonitis and abscess without meningoencephalitis or ocular dissemination, and esophageal candidiasis.
Several different fungal infections are treated with this medicine. Patients receiving stem cell transplants can also use it to avoid developing fungal infections. Echinocandins are the group of medications that micafungin is a member of. Drugs that contain an antifungal ingredient help treat fungi. They have the ability to stop fungi from growing and flourishing or to directly kill them.

Answer:
The idea of spontaneous generation was disproved by Francesco Redi.
Explanation:
- Spontaneous generation is a theory that states that living organism can generate from an inanimate object.
- In, 1668, Francesco Redi demonstrate an experiment explaining the theory of spontaneous generation by using meat.He noticed that flies laid eggs on meat which was kept open and maggots developed.
- He took three pieces of meat to do the experiment.
- The first piece of meat was kept open and as usual maggot development takes place.
- With the 2nd piece of meat,he covered it with a piece of cheesecloth and noticed that,flies lay eggs on the cheesecloth but when he removed the cloth,maggot did't form.
- Next, he took a piece of paper and cover the meat piece, and he noticed that flies did't lay any eggs and thus no maggots formed.
