Historically, the earth's ocean had a pH of 8.2. In recent years, it has dropped to 8.1. How might this change affect the ocean environment?
OA. The skeletons of coral will become soft due to increased acidity.
OB. The rise in alkalinity will make the ocean unfit for certain ocean plants.
Oc At 8.1, the ocean has reached neutral pH, making it identical to pure water.
OD. The ocean's CO2 content will decrease, improving the environment for animals.
The effect of this change of pH value in the ocean environment will be experienced by: (A). The skeletons of coral will become soft due to increased acidity
Meaning of pH value
pH value can be defined as the values that tells us how acidic or basic a mixture is.
pH is the measure of how acidic or how basic water is.
pH values ranges from 1-14, and each has its own significance. number 7 stands for the neutral point.
In conclusion, The effect of this change of pH value in the ocean environment will be experienced by: The skeletons of coral will become soft due to increased acidity

Why is the sustainability of water for the future generations to come so important
Answer:
The sustainability of water for future generations is important because water is the source of life, the substance that enables all living things to survive and develop. Water is at the core of sustainable development and is critical for socio-economic development, healthy ecosystems, and for human survival itself. It is vital for reducing the global burden of disease and improving the health, welfare, and productivity of populations. Therefore, water must be sustained for future generations in order to protect and preserve the environment and to move towards a sustainable development model.

individual species with which of the following characteristics would be most likely to survive according to Darwin?
a the smallest number of offspring
b variations best suited to the environment
c characteristics their parents acquired by use and disuse
d undergone mutations
Answer:
B
Explanation:
If variations are better suited to the enviro, you are more likely to thrive
Variations best suited to the environment, is the characteristic that would be most likely to help a species survive according to Darwin's theory. Therefore, option (B) is correct.
What is Darwin's theory?According to Darwin's theory of evolution by natural selection, individual species with variations best suited to the environment are most likely to survive and pass on their advantageous traits to their offspring. This is because individuals with beneficial traits are more likely to survive and reproduce, passing on those advantageous traits to their offspring, leading to the evolution of the species over time.
The other options are not necessarily advantageous for survival. For example, having the smallest number of offspring (option A) may not necessarily be an advantage in all situations, and characteristics acquired by use and disuse (option C) are not inherited and therefore cannot be passed on to offspring. Mutations (option D) can be beneficial or harmful, and their survival depends on their effect on the organism's ability to survive and reproduce in their environment.
Therefore, option B, variations best suited to the environment, is the characteristic that would be most likely to help a species survive according to Darwin's theory.

By planting corn one year and beans the next on a given plot of land, or by planting alfalfa as a cover crop during the off-season, a farmer reduces the need for ___________ because beans and alfalfa fix nitrogen in the soil.
Such a planting pattern will reduce the need for nitrogen-based fertilizers.
Rotational croppingIt is a system of farming in which crops of differing characteristics are planted alternately in two consecutive seasons.
For example, planting corn this season and beans the following season is a kind of crop rotation.
By doing so, the need for nitrogen-based fertilizer is reduced because legume crops are able to fix nitrogen into the soil through the association of their root nodules with ceratin nitrogen-fixing microbes.
