What happens to the phosphates when plants and animals die?

andrew-mc [135]

Answer:

When plants and animals die, organic molecules also undergoes decomposition and this causes the incorporated phosphates to go back to the soil or bodies of water.

Explanation:

Phosphates are naturally related to "phosphorus." They play a vital role in the life of animals and plants. Phosphorus can be commonly be found on the earth's land and water (although the land has a smaller amount of it). Plants naturally absorb phosphate from where they're growing. Animals take up phosphates by eating plants. The phosphate that plants get from the soil are considered inorganic. They only become organic when it is incorporated into the plants DNA (since this is an organic molecule).

So, this means that if there's a sufficient amount of phosphate, there will be more plants on earth as it is also important in the process of acquiring nutrients.

When animals and plants die, all of the organic molecules such as phosphate also breaks down and thus, it falls back to the soil or bodies of water. Then, they are ready to enter another Phosphorus cycle.

You track aquatic coastal levels of nitrogen and phosphorus at high latitudes and notice a sharp increase in the winter and then

nordsb [41]

Answer:

A considerable increase in phytoplankton populations in winter, and a greater increase in spring due to increase in light intensity.

Explanation:

Nitrogen and phosphorus are important nutrients required by phytoplankton populations. The growth of phytoplankton populations is dependent on the level of the availability of Nitrogen and Phosphorus in the presence of sunlight.

A rise in the aquatic coastal levels of nitrogen and phosphorus would result in a great increase in phytoplankton populations in spring, as stimulated by nutrient enrichment coupled with the availability of sunlight during spring. Phytoplankton populations would increase also in winter but not as high when compared to the rise in population in spring

Lysosomrs can be compared to the recycling and garbage centers of a city. How can this comparison be justified

IgorLugansk [536]

Lysosomes use a degenerative enzyme to eliminate un necessary materials from the cell and recycle parts that can be re used, much like a recycling centers eliminate waste from cities and find ways to reuse it.

The scientific attitude of skepticism is based on the belief that

denis-greek [22]

Answer:

Questions, hypotheses, and ideas should be tested against observable evidence.

Explanation:

Skepticism is extremely important, if not fundamental, in all areas of Science. This attitude is based on the belief that all questions, hypotheses, and ideas should be tested against observable evidence. Moreover, it allows scientists to question and think thoroughly about all possibilities behind a phenomenon, instead of just 'believing' any observation or vague and non-supported reason that explains it.

In addition, it allows researchers to investigate all possibilities and test numerous methodologies to be certain and gather enough evidence to explain this certain phenomenon.

The same sentences are written with a substitution, deletion, or insertion, much as a gene may have a substitution, deletion, or

strojnjashka [21]

Answer:

The question is incomplete, the complete question has been added as an attachment.

THE DGR AN represents deletion mutation

THE RED ANA TRA N represents insertion mutation

THE FOX WTS RED represents substitution mutation

Explanation:

Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.

An insertion mutation is the addition of one or more nucleotide bases to the sequence.

A substitution mutation is the replacement of one or more nucleotide base in a sequence.

The original sentences were:

1. THE RED ANT RAN

2. THE FOX WAS RED

3. THE DOG RAN

The three sentences that mutated/changed are:

1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.

2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.

3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.
