Prokaryotes divide by binary fission, a form of asexual reproduction in which
evablogger [386]

Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.

Explanation:

Binary fission and mitosis can be viewed as the same principle of  asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.

Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.

What is so special about nitrogen in the atmosphere
HACTEHA [7]

Answer:

Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.

Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.

Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.

Develop an argument from evidence on how human activity can lead to ocean acidification? Further explain what we can do, as huma
Sedaia [141]

Answer

Ocean acidification results from the solubility of CO2 in oceans increasing the H+ concentrations, and depletion of bicarbonates concentrations.

Therefore, human activities which increases the concentration of CO2 in the atmosphere, will raise the atmospheric  CO2 concentration. CO2 is constantly being absorbed by green plants maintaining   its concentration through carbon cycle,Therefore massive deforestation  which removes green plants, cutting  down photosynthesis is one of human activities which  raises CO2 levels of the atmosphere.The CO2 dissolves in  the oceans to raise its acidic levels.Lower pH.

Another source is fossil fuels emissions which add more CO2 to the atmosphere.

What is DNA, Example of DNA, Why is DNA important to our life
Alexus [3.1K]

Answer:

DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease.

Short for deoxyribonucleic acid. The nucleic acid that is the genetic material determining the makeup of all living cells and many viruses. ... An example of DNA is the chain of basic materials in the chromosomes of the human cell.
