Answer:
Los componentes básicos del ADN son los nucleótidos, que se componen de tres partes: una desoxirribosa (azúcar de 5 carbonos), un grupo fosfato y una base nitrogenada (Figura 9.3). Hay cuatro tipos de bases nitrogenadas en el ADN.

One function of gap junctions appears to be to cellular communication the activities of like cells in a particular area.
Connexins, membrane proteins that connect nearby cells, create tiny, fluid-filled tunnels known as connexons at gap junctions. Instead of being fused together like in tight junctions, the plasma membranes of gap junctions are separated by a very small intercellular gap (space).
Ions and tiny molecules can move from the cytosol of one cell to another through connexons. In avascular tissues like the cornea and lens of the eye, the transfer of nutrients and possibly wastes occurs through gap junctions.
Some of the chemical and electrical signals that control development and cell differentiation in a developing embryo travel through gap junctions.

Answer:
The scientific method <em>involves testing observations to derive a working hypothesis.</em>
Explanation:
The scientific method is a research method used to produce knowledge. It consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility (the capability of reproducing the experiment in any other place by any researcher) and refutability (susceptibility to be refused).
There are different steps to follow in a scientific method:
- Definition and problem statement. The question for which there is not an answer yet.
- Data collection and analysis. This step involves testing the observations.
- Verification of hypothesis. This step involves the deriving of the working hypothesis.
- Conclusions and Discussion.
