Answer:
The correct answer is Option B (Carrying out research). The step that follows this step involves forming B.a conclusion
Explanation:
The Natural environment around us is a function of both the living things and the non-living things. So, environmental science is the study of the natural environment around us. This study includes how to tackle environmental problems and further study on how humans could be impacted by the interactions with their environment. The scientific method is a step taken towards ensuring development in a field by bringing new discoveries and challenging existing beliefs through scientific tests and research. Generally, for most scientific methods of many fields, it starts with:
1. Observations
2. Making inquiry which involves asking questions
3. Forming a hypothesis, which means making untested assumptions
4. Conducting an experiment to check the hypothesis
5. Analyze the results
6. Publish the results
The correct answer is Option B (Carrying out research). Because it involves the scientific method highlighted above. The step that follows this step involves forming B.a conclusion
Tretinoin is a naturally occurring metabolite of retinol in the retinoid class, including natural and synthetic analogues. It is the acid form of vitamin AIt acts on cell growth and differentiation. Its main use is the treatment against acne thanks to its keratolytic and anti-inflammatory properties. Tretinoin is also used in the treatment of acute myeloid leukaemia type 3 (AML 3).

I would go with D, speaker. A poem is written by an author, but the author isn't always the speaker.
Ionic bonds <span>are the type of bonds where there is </span>transfer<span> of electrons from one atom to another. The electrons are removed and from one atom and attached to another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.</span>
