What do you think the pH of water is?

Answers

The pH of pure water is considered to be neutral so it has a pH of 7. However, if you have water that falls below this range, the solutions or substances are considered to be be more acidic than than normal water. On the other hand, if you have water above 7, it is considered alkaline or basic.

In the process of distillation, during condesation the temperature of water decreases Hence absorption of CO2 takes place and some H2CO3 is formed. This is an acid (though very weakly) so water turns acidic. Double distillation enhance this so theoritical pH is 7.0 but practically less than 7.0 (6.2 to 6.8)

a mimic octopus has lost some of its arms, and is in the process of regeneration. Describe a scenario where this ability would provide the octopus an advantage in its environment.

Answers

Answer:A shark tries to eat an octopus they fight but the octopus ends up victorious. The shark only got away with one tentacle,

But fortunately for the octopus it will grow back.

The ability of the octopus arm to regenerate is an advantage in the case of

interaction with larger predators.

The octopus is a marine organism which is characterized by the eight arms.

It uses these structures to find food for its survival. The octopus are eaten by

larger predators such as shark, whale etc.

During the interaction with these large predators, there is a possibility of its

arms being eaten alone instead of its whole body which provides it with the

advantage of survival and regeneration of arms for subsequent finding of

food.

Look at the bean from Days 4-6. Use these data to explain how natural selection changed the number of dark red walking beans over time.

Answers

Answer:

When the volcano erupted, the dark red walking beans were easier to see. Thus, more dark red beans were eaten during days four, five, and six. If the pollution continued, there would be fewer and fewer dark red walking beans over time.

Natural selection changed the number of dark red walking beans over time because, after the volcanic eruption, the dark red beans were clearly visible to predator's eyes; hence, they were picked and eaten by them. As a result, their population decreases.

What is natural selection?

Natural selection is applied to nature where the environment selects animals and plants that it wants to keep, and this is the result behind diversity in the different ecosystems. The availability of resources in nature prevents the desert from having the same diversity as the tropical rain forest. Nature selects the organisms that are best suited to the environment and reproduces to produce future generations.

Here, the dark red beans were not initially visible, but they became readily visible after the volcanic eruption, which let the predator see them and eat them. Slowly, due to this, their population declines, and this happens due to natural selection.

Hence, as the dark red beans are clearly visible to predators' eyes, and their population is declining.

sustainable use is: water systems in the realm of sustainable development may not literally include the use of water, but include systems where the use of water has traditionally been required. Examples include waterless toilets and waterless car washes, whose use helps to alleviate water stress and secure a sustainable water supply
-
unsustainable use is: world's water use may be unsustainable. ... These practices can have an important influence on what scientists call “evapotranspiration,” which is water that is lost to the atmosphere by either evaporating from the Earth's surface or being taken up by plants and later released into the air through their leaves.

food -
sustainable use is: Local & seasonal,
Organic & sustainable farming,
Reduce foods of animal origin & maximise welfare standards,
Excludes fish species identified as at risk,
Fair-trade-certified products,
Promote health and well being,
Food democracy and
Reduction of waste and packaging
-
unsustainable use is: Foods containing high fructose corn syrup (HFCS) are especially bad for the environment. Not only does consumption of HFCS increase the likelihood of obesity and health problems, but production is extremely energy intensive,
Seafood listed in the “avoid” column on the Seafood Watch list and

How long does adaptation usually take? (Plant)
1.a decade
2.an hour
3.A few days
4.Centuries

Answers

Answer: The answer is (4), centuries

Explanation:

Plant adaptation is a long-term process that occurs over many generations. It is driven by natural selection, which is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. Hence option D is correct.

The rate of plant adaptation can vary depending on the environment and the plant species. However, it is generally a slow process that takes many years or even centuries to complete.

For example, some plants have adapted to the cold temperatures of the Arctic over millions of years. These plants have developed thick, waxy leaves that help to insulate them from the cold, and they have also developed a slower metabolism that allows them to conserve energy.

Other plants, such as weeds, can adapt to new environments more quickly. This is because weeds are often generalists, meaning that they can survive in a wide range of conditions. They can also reproduce rapidly, which allows them to quickly spread to new areas.
