<span>The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
</span><span>To date materials the procedure of radiometric dating or
radioactive dating is used, for example, rocks or carbon, in which trace
radioactive impurities were specifically fused when they were framed. The
strategy looks at the abundance of a normally happening radioactive isotope
inside the material to the abundance of its decay items, which shape at a known
consistent rate of decay.</span>
Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would
- The amount of food increased or decreased
- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa
Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.
Muskrats eat oak trees and if the oak tree had a disease and all of them died. then the muskrat would have to relie on someething else to eat because muskrats eat oak trees.
Answer:
primer
Explanation:
Most biological reactions rely on the enzyme to speed up the reaction. In the case of DNA replication, this enzyme is DNA polymerase. a; DNA is a double helix made up of two long chains of deoxyribonucleotides. ... b; a primer is used to start this process by giving DNA polymerase something to bind the new nucleotide to. just for you to see.
The process whereby the binding of antibodies to antigens causes RBCs to clump is called: agglutination.
