Why do classification systems change over time?
O Scientists find new evidence in their studies.
O Scientists use old methods of classification.
O Scientists repeat experiments and find no changes.
O Scientists find similar evidence to previous work.
Classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).
What is Classification System?There are many types of classification systems that are used for different purposes. The classification of organisms takes place in the form of a classification system called Linnaean classification.
Linnaean classification involves the use of organisms grouped using a hierarchy called taxa which includes taxonomic levels and taxonomic groups that animals are placed in based on their characteristics and even shared ancestry.
The different levels of biological classification are as follows:
Species » Genus » Family » Order » Class » Phylum » Kingdom » Domain
It changes over time as scientific studies find new evidence.
Thus, classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).

If there is 0 % pollution is produced in the environment, the environment growth will be increases and equilibrium of environment should be accomplished.
Explain how nitrate ions help plants to grow.
Answer:
Explanation:
Both nitrate ions and ammonium ions can be taken up by plants (some prefer one to the other). These ions provide nitrogen for the plant to make its own amino acids for protein synthesis. Except in very high nitrogen soils, the addition of extra nitrate will stimulate plant growth.
Nitrogen is an essential macronutrient that is a component of many essential molecules, such as amino acids, proteins, nucleic acids, and chlorophyll.
What are the roles of nitrate in the growth of plants?Nitrate ions are essential nutrients for plant growth and development. Nitrogen is the fourth most abundant element in plants and is crucial for the growth of leaves, stems, and roots.
Plants require nitrogen in the form of nitrate because it is the most oxidized. It is an easily available form of nitrogen for plants to take up from the soil. Nitrate is absorbed by plants through their roots and transported to the plant cells, where it is used to synthesize amino acids, proteins, and other essential molecules.
Nitrate plays a crucial role in the process of photosynthesis, which is the process by which plants convert sunlight into energy.

a) CCG GCA AAG TGG
b) CCG GCU AAG TGG
c) CCG GCU AAG UGG
d) CCG GCA AAG UGG
Answer:
The Answer is D, trust. I got all of them wrong and the system showed that this was the correct one.
Explanation:
The transcription of G G C C G T T T C A C C to mRNA is CCG GCA AAG UGG. Hence, option D is correct.
What do you mean by Transcription?Transcription may be defined as a biological process that involves the transformation of a DNA strand into its mRNA sequence. It occurs in the nucleus of the cell.
In mRNA, Adenine is transcribed into Urcail instead of thymine. So, the mRNA sequence will be synthesized according to that.
Therefore, the correct option for this question is D.
