Photosynthesis is the process that converts energy from sunlight into energy in food. In the dark phase, the ribulose bisphosphate added to the carbon dioxide gas (CO2) in the air results in the production of organic compounds.

Any of the chemical reactions that take place during the second stage ofphotosynthesis and do not require light. During the dark reactions, energyreleased from ATP (created by the light reactions) drives the fixation ofcarbon from carbon dioxide in organic molecules. The Calvin cycle formspart of the dark reactions. As long as ATP is available, the dark reactionscan occur in darkness or in light.

Match each step of the scientific method with the order it usually occurs in. 1. 1st Step data collection 2. 2nd Step communicat

AysviL [449]

Answer:

1st Step: Observation

2nd Step: Questioning

3rd Step: Data Collection

4th Step: Data analysis

5th Step: Communication

In the scientific method, the first step is always to make an observation. You can observe anything in your environment, or a phenomena, or behavior.

The next step would be to question. You form a question to find a possible explanation as to why what you had observed occurred. This is also when you make a hypothesis. An educated guess or a proposal that could explain the event.

After you make a hypothesis, you start an experiment where you will collect data. The data you collect would then be analyzed (4th step). From there you build your conclusion to determine whether your hypothesis holds true.

The last step would be communication. You will communicate the results of your method. This allows people to review your data and process, which may be supported or invalidated. Communication is critical in the scientific world because your results could be the basis for further investigation.

Lelechka [254]

Answer:

In order to clone the sequence of the gene for one of the human crystallins found in the eye, there is a need for the application of polymerase chain reaction. In the process, the particular sequence of gene is denatured and then replicated various times to generate various clones of the gene sequence.

By producing various copies of the gene sequence for the human crystallin, that is, desirable, a scientist can examine various distinct characteristics of the protein as there is always more to examine with.
