Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.
To find: The total population size of the frogs in the pond.
Method: Using unitary method of proportions
Solution:
Let p be the density of the frogs present per square meter.
Let A denote the total area of the pond.
∴ p = 12 frogs/m² and A = 370 m²
The total number of frogs in the pond is given by,
Therefore, there are 4440 frogs in the pond.
Because it helps them with finding new researches.
Answer:
Spores
Explanation:
Spores are small structures produced in large quantities by bacteria (as well as fungi and plants), capable of generating a new individual.
Bacterial spores (or endospores) act as survival structures when bacteria are found in unfavorable environmental conditions.
They are produced by the bacteria themselves and are found freely inside of them. The position where the spores are found is used as a way of identifying the species of bacteria.
While in the form of spores (which can be viable even for centuries for some species), the bacteria are resistant to heat, dehydration, radiation and pH variations.
When the environmental conditions are <u>favorable</u>, the spore absorbs water until it swells and breaks. From there, germination occurs, producing a cell identical to the parental cell, reactivating the metabolism, as well as the multiplication and growth of new bacteria.
