What do climate change (see Concept 1.1 and Concept 3.2) and ocean acidification have in common?
leonid [27]

Answer:

They are caused by an increase in global temperatures

Explanation:

Global warming will cause a change in the weather patterns of a region – called climate change. A place could experience extreme weather such  as increased dryness or wetness.  This is mainly due to takeup of this heat by the oceans hence influencing global currents.

As the oceans become warmer, they are able to absorb more carbon dioxide from the atmosphere. This causes these water to have a higher acidity than normal because of the formation of carbonic acid.

taurus [48]

Non - biodegradable and lipid soluble are the properties of toxic-ant that are likely to build up in animals through bio-accumulation.

In this chemical such as PCSs, DDT , dioxins, and mercury are all persistent chemicals. Because they don't break down and go away , these chemicals are problems . Toxicants that travels through the environment mainly by means of air and water .

Bio-accumulation is the toxic-ant which buildup the tissues of an animals. Bio-magnification is when toxins moves higher concentrations as they move to higher tropic levels. Toxicity is associated with the bio-accumulation and bio-magnification and storage of metals faster than the rate at which an organism metabolizes and excretes lead to the accumulation of that metal.

Where within the DNA molecule is the genetic code?
TEA [102]

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
