The pH is a measure of the concentration of the hydrogen ion (H+) in water. Highly acidic water has a very high H+ concentration, while basic water has very low H+ concentrations. The pH scale is a logarithmic scale, such that a difference of one pH unit means a 10-fold difference in H+ concentration. The mathematical relationship between pH and H+ concentration ([H+]) is
pH = –log [H+] OR [H+] = 10-pH where [H+] is in moles per liter.
Use a scientific calculator to calculate [H+] for the following pH values:
7 (a neutral solution)
5.6 (unpolluted rainwater)
3.7 (first acid rain sample in North America)
How many times higher is the concentration of H+ in the Hubbard Brook sample than in unpolluted rainwater?
The hydrogen ion concentration of the following pH samples is as follows:
7 (a neutral solution) = 0.8455.6 (unpolluted rainwater) = 0.7483.7 (first acid rain sample in North America) = 0.568How to calculate hydrogen ion concentration (H+)?The pH is a measure of the concentration of the hydrogen ion (H+) in water. This means that a relationship exists between H+ and pH of a solution.
The mathematical relationship between pH and H+ concentration ([H+]) is as follows:
pH = –log [H+]

The correct answer is as follows.
This is because my parents were heterozygous for the color of the beans. The color of the plant beans is the case of simple Mendelian laws, as there are only two choices for the color of the beans.
What is the meaning of Mendel's laws?Mendel's laws refer to a specific pattern of how a trait is passed from parent to offspring. These common patterns were established by the Austrian monk Gregor Mendel, who conducted thousands of experiments on bean plants in the 19th century.
What is an example of a heterozygous?If the two versions are different, the genotype of the gene is heterozygous. For example, a heterozygous hair color means that there is one red hair allele and one brown hair allele. The relationship between the two alleles affects which trait is expressed.

VALUE BASED QUESTION (Write in about 50-100 words)
Consider the following two cases: (Please give answer ASAP)
(i) A forest that is rich in biodiversity sees a decline in the animal population and clearing of a large
part of the forest. The Government declared it as a biodiversity hotspot and the forest regained its
species richness in few years.
(ii) A lake that is rich in marine fishes sees a decline in its species population due to over harvesting.
The people living in the area made the lake a sacred grove and started worshipping it. The species
population of the lake again became normal.
Answer the following questions based on the above information:
(i) Which values are being promoted in the above cases?
Case 1:-
Case 2:-
(ii) Suggest some ways in which you can contribute to this concern.
Case 1:-
Case 2:-
(iii) What would have been the effect if the forest was not declared a biodiversity
hotspot?
The value that can be withdrawn from case 1 is the activeness of the government that takes some crucial steps to maintain the biodiversity of the forests. The value that can be withdrawn from case 2 is the sincerity of native people towards nature who make a lake a sacred grove and start worshipping it in order to maintain the biodiversity of that lake.
What is Biodiversity?Biodiversity may be defined as the sum total of all the living entities living in a particular area at a given time.
For maintaining the biodiversity of the forest as well as a lake, it is required not to deteriorate the natural ecosystem of those regions by human activities like over grazing, forest fires, over harvesting, industrialization, etc.
If the forest has not been declared a biodiversity hotspot, the time will not be far to announce that a forest becomes a bare area, where no species live, survive, and reproduce naturally.
Therefore, it is well described above.

Fossil fuels are made when....
A. organisms don't fully decompose and become
trapped underground
B. organisms collide at high speeds during
catastrophic events
C. bedrock is liquidated due to shifting tectonic
plates
D. volcanic ash is liquidated under extreme pressure
Answer:
A
Explanation:
a - What happens when organisms don't decompose? If there were no decomposers, wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.
b - What happens when a catastrophic mass extinction occurs? A mass extinction event is when species vanish much faster than they are replaced. This is usually defined as about 75% of the world's species being lost in a 'short' amount of geological time - less than 2.8 million years
c - What does the shifting of tectonic plates cause? At the “seams” where tectonic plates come in contact, the crustal rocks may grind violently against each other, causing earthquakes and volcano eruptions. The relatively fast movement of the tectonic plates under California explains the frequent earthquakes that occur there.
d - Volcanic ash doesn't actually do that.
Now, how do fossil fuels form? After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Fossil fuels are formed when the organic matter that has been buried deep within the earth is subject to heat and pressure over millions of years. In both cases, heat and pressure are critical to the formation of fossil fuels.

Hospital-Acquired MRSA – is associated with infections that are caused due to exposure to hospital or nursing home environments.The infection can be caught through direct contact or contaminated hands. Sometimes touching used surgical instruments or infected bedsheets can also pass on the infection leading to severe pneumonia or blood infections.
