Answer:
sedimentary rocks
Explanation:
can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years. So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil.
Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.
Answer:
This question is asking to complete and balance the equation as follows:
C6H1206 + 602 → 6CO2 + 6H2O
Explanation:
The equation described in this question is that of cellular respiration, which is the process whereby glucose is broken down to release energy (ATP) needed by the cell.
- The inputs of this equation are glucose (C6H1206) and oxygen (O2).
- The outputs of the equation are carbon dioxide (CO2) and water (H20).
According to this question, to balance the inputs and outputs of cellular respiration, there should be the same number of carbon, oxygen, and hydrogen atoms on each side of the arrow as follows:
C6H1206 + 602 → 6CO2 + 6H2O
Note: the equation is not balanced as it is written in the question.
Answer:
Which of the following is not an effect of meiosis?
Causes more genetic diversity in sexually
Explanation:
Answer:
pruney fingers are caused by shrinking blood vessels. When you soak in water, your nervous system sends a message to your blood vessels to shrink. Your body responds by sending blood away from the area, and the loss of blood volume makes your vessels thinner.
