Answer:
2.5 mg
Explanation:
<em>The half-life of a substance is the time required for one half of the substance to decay. In order words, it is the time it will take for a substance to decay into half of its initial size.</em>
For a 20 mg element with a half-life of 30 which decays over a period of 90 years;
The first 30 years, 10 mg would have decayed, remaining 10 mg
The second 30 years, the remaining 10 mg would have decayed to 5 mg
The third 30 years, 5mg would have decayed to 2.5 mg.
Hence, in 90 years, 20 mg of the element would <u>remain only 2.5 mg.</u>
Answer:
The hyphae of fungus serve as the main mode of vegetative growth.
Mycelia and hyphae are use to absorb nutrients from other organisms.
Explanation:
Fungi are either unicellular or multicellular organisms that are found in moist, slightly acidic and low oxygen environment. They are heterotrophs and decomposers.
Their cell walls are rigid and are composed of chitin and glucans. They are characterized by long filamentous structure called hypae. The structures of hypae form the mycelia.
