In microbiology laboratory, broth is very vital. Its purpose is to provide growth medium for the available bacteria necessary for working on the nutrients. Broth gives steady and constant nutrients for the bacteria to quickly reproduce. It is normally a clear liquid made from bones, meat or vegetables.
The specific term to characterized the downward
growth of roots in response to earth’s gravity pull is called positive geotropism.
The word geotropism was derived from two words, “geo” which means ground and “tropism”
which describes a plant movement elicited by a gravitational stimulus.
In addition, the root cap makes the roots turn
downward as they grow for they have specialized cells with sensors called
statoliths that settle to the lowermost part of the root cap in response to the
pull of gravity and help the cell multiply more rapidly in a downward direction.

Answer:
C) behavioral isolation
Explanation:
The mechanisms of reproductive isolation that prevent the formation of a zygote by interbreeding between the individuals of two different species are called pre-zygotic isolation mechanisms. Behavioral isolation is one of such pre-zygotic isolation mechanisms. It includes the exchange of specific signals between the individuals of the same species before mating. Such specific courtship behaviors represent behavioral isolation.
Different species of fruit flies exhibit specific courtship behaviors such as fighting and display to attract the females of the same species only. These signals are not identified by females of the other species. It represents behavioral isolation.
Bacteria has a hard time getting inside a dry egg. Washing eggs removes the bloom and allows bacteria into the egg. Washing eggs in cool water pulls bacteria in even faster
Answer: you would then put more sand on top and wait then a little more water!
Explanation:
Because you have to sublimated the leaves
