Answer: Most rocks do not contain organic material-most fossils are not organic anymore. One of the most common isotopes used in radiometric dating is uranium-235 or U-235. ... This makes it useful for dating rocks that are very old. Radioactive isotopes with short half-lives cannot be used for dating old rocks.
not 100% sure :/
Hi my dear friend,
The ground shaking may also cause landslides, mudslides, and avalanches on steeper hills or mountains, all of which can damage buildings and hurt people. The second main earthquake hazard is ground displacement (ground movement) along a fault.
~Thank you
Active genes are found in the EUCHROMATIN of eurkaryotic chromosomes.
Euchromatin is a type of chromatin which is composed of DNA, RNA and proteins and which is enriched with active genes. Euchromatin is the most active portion of the genome inside the cell nucleus. For humans, 92% of their genome is made up of euchromatin.
The answer is obviously not C as urine comes out of your urethra, so the answer is a and b
The probability that of the F1 offspring will have red pear shaped fruit 0%.
c. 0%
<u>Explanation:</u>
Given-
Red color (R) is dominant over yellow (r) fruit color
Round shaped (F) is dominant over pear shaped (f) fruit
Yellow pear shaped = rrff
Heterozygous for red fruit and homozygous for round shape = RrFF
Gametes of rrff = rf , rf, rf, rf
Gametes of RrFF = RF, RF, rF, rF
Performing a cross between these gametes would give -
The cross performed is attached as a word file for your reference.
According to the cross,
The probability of red pear shaped fruit is 0%
