Answer:
C
Explanation:
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.
Hydrogen is the lightest element on the periodic table of elements. Hydrogen gas is always bonded to itself or something else to fill its outer shell. That is why hydrogen gas is represented as H2. Hydrogen<span> is odorless, colorless, and tasteless; therefore, it is undetectable by human senses.</span>
Answer:
These crops where improved with technology, production of high-yielding variety, and improve farm practices. All these ensured the crops of green revolution had increase yield.
Explanation:
Through genetic engineering, high-yielding variety of cereals e.g wheat, maize, rice, were genetically engineered so that certain features which enhanced increased productivity were selected for.
Use of fertilization, the adoption of mechanization,good cropping and farming system are other factors which enhanced yield of these crops. Specifically, these crops were modified to enhance their Nitrogen uptake, which promotes rapid growths.
The process of meiosis is the cell division that prepares the species for sexual reproduction. Through meiosis cells goes from diploid (2n) cells to haploid (n) gamates. Each daughter cell carries exactly one half of the genetic material from the mother cell. In females the result of meiosis is the production of egg cells, where in the male, the result of meiosis is the production of sperm cells.
