The statement that explains why carbon-14 cannot be used to date rocks is : ( C ) Carbon-14 can be used only to date the remains of organisms
<h3><u>What is carbon-14 dating</u></h3>
Carbon-14 dating ( radiocarbon dating ) is used to determine the age of a material or substance which must be part of a living organism that has once existed or is still existing.
Carbon -14 dating cannot be used for determining the age of ancient rocks because of :
- The half life of carbon-14 dating and
- Ancient rock materials are not part of a living organism
Hence we can conclude that The statement that explains why carbon-14 cannot be used to date rocks is : Carbon-14 can be used only to date the remains of organisms.

Answer:
Ferns are one of the oldest plant groups. Moss is first though.
Explanation:
Answer:
0%
Explanation:
From the information given;
Assume that the dominant "B" allele encodes brown eyes ; and
the recessive "b" allele encodes blue eyes
If genotype BB × genotype bb, the percentage of chance that they would have children with blue eyes will be zero ...Let look at the cross
BB × bb
We have all the progeny as Bb, Bb, Bb, Bb ....i.e the genotypic information are all heterozygous brown eyes, this is because The allele B mask the recessive "b" allele which makes the allele B (brown eyes) to be dominant over allele b (blue eyes).
Answer:
See the answer below
Explanation:
From the graph, the concentration of salt solution where the number of burst red blood cells equals the number of intact ones is 0.40 g/100 cm3<u>.</u>
<em>At this concentration, the percentage of burst cells is 50, meaning that the remaining 50% of the cells in the experiment remained intact.</em>
The totality of the concentrations of all the salt solutions used is:
0.30+0.35+0.40+0.45+0.50 = 2 g/100 cm3
Thus, the percentage of salt solution concentration when the number of red blood cells that burst is the same as the number of red blood cells that do not burst equals;
0.40/2 x 100% = 20%
Not the plants but the soul could be made into mud in both past and present. In past, most houses(not in the US) but in many countries were made up of soil. But know in present, soil or even mud is used to put it in the concrete to make the building strong in many countries like India. Good luck:)
