10. which materials are most likely to be part of a stream's dissolved load?
02
o a. pebbles
ob. cobbles
c. sand grains
d. minerals
enviou all be highlighted on the review nane)

D.  Minerals

Explanation:

The question is asking for which of these things could be part of a stream's dissolved load.  Pebbles, cobbles, and sand grains can not dissolve, but minerals can.

I hope this helps!

option (D)

Explanation: In order to be a dissolve load of a stream, the particles must be of smaller size and less dense. Pebbles and cobbles are of size about 4-64 mm and 64-256 mm respectively

Sand grains are usually 0.125-2 mm in size but have a high average density

In case of minerals, it varies as some minerals are found to be bigger and some appears to be smaller in size. Minerals have the ability to get dissolved when undergoes chemical reactions.

Thus, the correct answer here is option(D) i.e. minerals which is most likely to be a part of the stream's dissolve load.

the answer is

c. parental

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
