Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

Answer:
The correct answer would be - increase in green house effect, increase in temperature and rise in sea level are some major response.
Explanation:
Carbon dioxide concentration soar over 400 ppm which means there are 400 particles of carbon dioxide in a million particles of air. It is on the highest level of all time from the beginning. Carbon dioxide is a green house gas which means it is able to absorb heat and trap it in air which leads to increase in temperature of the earth.
Increase in earth temperature will lead to melting of ice lands which result in rise of sea level and cities will drown in sea. Other effect will be pollution in atmosphere and warmer climate and change in pattern of climate. There are many other direct and indirect response in accumulation of carbon dioxide concentration.

<em>The law of segragation, the law of independent assortment, and the law of dominance.</em></h2>
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells in order that sex cells contain only 1 gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for various traits are sorted separately from each other in order that the inheritance of 1 trait isn't smitten by the inheritance of another.
3) The Law of Dominance: An organism with alternate types of a gene will express the shape that's dominant.
