Answer:
It is essentially a broth culture filtrate of the penicillium mould.
Explanation:
- Alexander Fleming invented penicillin an antibiotic in 1928. These have been rated as the most important scientific discovery, being among the first antibiotics to be effective against bacterial infection.
- Penicillin belongs to different families that are selective against a large variety of bacteria.
- In fact, this antibiotic was discovered by fleming and accident in which he left a platter containing staphylococci open and was contaminated by green mould. There was an area of inhibited bacterial growth around the mould from which he inferred that the mould produced a material that inhibited bacterial growth. This was found to be a penicillium mould through further study.
- I assume penicillin is the most significant discovery so far because it was the first antibiotic ever discovered against bacterial infection in the absence of any drug.

Answer:
d. budding
Explanation:
Budding is a type of asexual reproduction, as are binary division, multiple division, vegetative propagation, and fragmentation. This type of reproduction is observed in some species of animals and plants.
In budding, as the name suggests, sprouts appear on the surface of the organism. These shoots will give rise to a new individual, which may grow on the organism that originated it, forming the colonies, or be released into the environment.
This type of reproduction is common in several plant species, occurring more frequently in angiosperms, and also in some animal species, especially in the cnidarian and porifer group.
The brain damage include in Broca's area. Broca's area is a
part of the frontal lobe of the left cerebral cortex near the motor cortex. Damage results in some language
disability. Aphasia refers to a condition in which there is severe
language impairment.
