Write down the two key components of the greenhouse effect.
Carbon dioxide (CO2) and Methane (CH4) are the two key components of the greenhouse effect.
Burning fossil fuels (coal, natural gas, and oil) releases carbon dioxide into the atmosphere, as well as as a byproduct of some chemical reactions, solid waste, trees, and other biological materials (e.g., manufacture of cement). As part of the biological carbon cycle, carbon dioxide is taken up by plants, where it is then "sequestered" (removed from the atmosphere).
When coal, natural gas, and oil are produced and moved, methane emissions occur. Agricultural techniques, land usage, and the decomposition of organic waste in municipal solid waste dumps all contribute to methane emissions, as do cattle and other agricultural activities.

for harebell plants, dominant alleles for two separate genes are needed to produce blue petal color. suppose gene 1 has alleles p and p and gene 2 has alleles b and b. only plants with at least one p allele and at least one b allele will have blue petals; all other genotypes lead to white petals. for the cross ppbb x ppbb, what fraction of the offspring are expected to have white petals?
The fraction of the offspring of the cross PpBb × PpBp with the expected number of plants with white petal color will be 7:16 i.e., out of 16 offspring 7 will have white petals.
What is Epistasis?Epistasis is a phenomenon in which the effect of a single gene mutation is dependent upon the presence or absence of mutations in one or more different genes, termed as the modifier genes. The effect of the mutation is dependent on the genetic background of cell in which it appears.
In epistasis, more than one gene controls a single character in an organism. Here, the ratio for petal color is 9:7 where, 9 of the petals are colored whereas 7 are white colored petals. As, the formation of colored petals requires the dominant alleles for both the genes.

What is the difference between G1 and G2 phases?
During G1 phase in mitosis the cell undergoes the first growth, in which the organelles are being copied and the cell prepares for the duplication of DNA. The DNA is copied during the S phase and the G2 phase starts after that. During the G2 phase, the cell undergoes the second growth, in which proteins and organelles are still replicating but also preparing for cell division.
So, during G1 phase the DNA is not duplicated, and during G2 phase it is.
During G1 phase occurs the frist growth, and during G2 phase occurs the second growth.
During G1 phase the cell prepares for DNA duplication, and during G2 phase the cell prepares for cell division.
Answer:
The G1 phase is the first phase of the interphase of the cell cycle in which the cell shows growth by synthesizing proteins and other molecules.
The G2 phase is the third phase of the interphase of the cell cycle in which the cell prepares for nuclear division by making necessary proteins and other components.
