Answer:
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.
Explanation:
Answer:
Enzymes attached with the body of substrate and speedup the reaction.
Explanation:
Enzymes attached with the body of substrate i. e. starch and increase the speed of break down and when the substrate is broken down, these enzymes detached from the substrate. Enzymes are the chemical substances present in the body of organism which helps to speedup the process of digestion. The digestion of starch starts from the mouth with the help of salivary enzyme and this starch is converted into smaller molecules which can be absorbed by the cells.
Its the person's offspring have mutated skin.
because for a mutation to be passed down to an offspring mutation has to happen in the sex cells. so that is the least likely to happen.
since the other may happen for example.
skin cancer: i am not sure how but definitely sure that it is the second least that is gonna happen. (trust me)
reduced functioning of skin cell yes.: if there are changes in the nucleotides which can give a diff amino acid.
and no change. cuz if the mutation occurs but the nucleotides still codes for the same amino acid then there is no problem!!
Answer: It is a complex, folded chain that helps regulate cell processes". The monomers of a protein are amino acids. Many amino acids form a long linear chain to become peptides which is the primary structure of a protein molecule.
