As newer rock layers form, they overlap with the ones with the pre-existing ones. Therefore, when looking for older rock layers, we would look for the ones that are deeper beneath the surface of the earth. On the other hand, newer rock layers are found at the top. This is also observed in the fact that oil rigs dig very deep into the ground to access the layers that are millions of years old.
The independent variable is the chemicals and the dependent variable is the plant growth.
Answer:
this is true
Explanation:

hope this helped
Answer:
The correct answer is - option A. 0%
Explanation:
The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.
The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.
percentage of chloroplast gene inherited from R plant is a)0%
Answer:
Due to no transfer of resistance allele.
Explanation:
The gene flow was not the cause of antibiotic resistance because the characteristics can't be transferred from one generation to the next generation. The organisms are evolved to become an antibiotic resistance due to their environmental conditions and this resistance quality is only present in the existing population and the alleles that are responsible for this resistance can't be transferred from the bacteria to the next generation so the experiment showed that gene flow was not the cause of antibiotic resistance
