scZoUnD [109]1 year ago
5 0

The lake's pH has become acidic; in 1989, it was 6.7; by 1996, it had dropped to 5.1. This shows that the increase in the acidity which has several bad impacts on the lake water ecosystem and its community.

<h3>What happens when the freshwater becomes acidic?</h3>

The freshwater ecosystem differs from the oceanic saltwater ecosystem in that freshwater contains phytoplankton, edible fish, and so on. The fresh water has a normal pH, but the pH decreases and induces acidity when the water is polluted with different chemicals, such as nitrogen oxide, sulfur dioxide, etc.

When acid rain happens due to man-made pollution, this further adds acidity to the fresh water, and as a result, the species that live in the lake are not able to live and breathe properly due to a lack of oxygen. The acidity in the table increased year after year from 1989 to 1996.

Hence, the acidity of the lake increased and the pH decreased in these years, from 1989 to 1996.

Pepsi [2]

Answer: The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties.

Explanation:

Starch and Cellulose flare both polysaccharides which are constructed from the same monomer called glucose. The functions they provide in plants are different which includes the following:

- STARCH is used by plants for energy storage because unlike Cellulose, it's formed from glucose units( oriented in the same direction) connected by alpha linkages which can form compact structures that can easily be broken down.

- Cellulose provides structural support for plant cell wall because unlike Starch, it's formed from glucose units( which rotates 180 degrees around the axis of the polymer backbone chain) connected by beta linkages. This pattern gives Cellulose it's rigid features as is allows for hydrogen bonding between two molecules of Cellulose.

Therefore the statement that best describes why starch and cellulose provide different functions in plants is that (The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties).

Olin [163]

Answer:

nucleosomes = 1.65 x 10^6

H2a = 3.3 x 10^6 molecules

H2b = 3.3 x 10^6 molecules

H3 = 3.3 x 10^6 molecules

H4 = 3.3 x 10^6 molecules

Explanation:

It was mentioned in the book Principles of Genetics  By D. Peter Snustad, Michael J. Simmons that in the nucleus of <em>D. melanogaster </em>there will be 1.65 x 10^6 nucleosomes and 3.3 x 10^6 molecules of every type of histone i.e. H2a, H2b, H3, and H4 present in it.
