Scientists hypothesize that prokaryotes evolved before eukaryotes because
a. ribosomes closely resemble prokaryotic cells.
b. the meteorites that have struck Earth contain fossils only of prokaryotes.
c. the oldest fossilized cells resemble prokaryotes.
d. laboratory experiments have produced ribosomes abiotically.
e. prokaryotic cells lack nuclei.

e. prokaryotic cells lack nuclei.

Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.

the answer is c. altitude. hope this ! #brainiac

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.
