<span>Question: </span>the amount of compostable waste that could be generated by one individual in a week would be closest to?
Given:
Average waste generated by an American per day = 2kg
Proportion of the waste that can be composted = 60%
Solution:
Let X = the amount of compostable waste generated by one individual in a week
X = X2kg*60%*7 days
X = 2(.6)(7)
X = 8.4 kg

Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.

Dandelion = taraxacum
Black eyed Susan= Rudbeckia hirta,
Evening primrose=OenThera biennis
Spring forget me not/spring scorpion grass = Myosotis verna.
Daucus = Dacus carota

Asexual reproduction = Binary Fission = Mitosis
The cell at the end of asexual reproduction compare to the original cell: at the end is called daughter cell, at beginning is parent cell; both have same number of chromosomes (2n = diploid).
