Answer:
The statement that accurately describes how scientists collect data is the method used to collect data depends on the desired data.
Explanation:
When a scientist decides to conduct research, he or she must consider the purpose of the research and the best way to conduct it. Once the purpose of the research has been defined and the hypothesis has been put forward, data collection becomes one of the most important steps.
Data collection must be adapted to the needs of the phenomenon to be studied, taking into account the most appropriate and reliable methods to achieve the objective.
<em>An adequate data collection method means choosing the best option to collect the necessary information and obtain the expected results in the investigation.</em>

Answer:
the layer of the earth's atmosphere that contains a high concentration of ions and free electrons and is able to reflect radio waves. It lies above the mesosphere and extends from about 50 to 600 miles above the earth's surface.
Explanation:
Answer:
Key points
Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron—another cell.
Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.
At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.
Explanation:
Pigments absorb light used in photosynthesis.Set of wavelengths that a pigment doesn't absorb are reflected.
Answer: The given statement is true.
Explanation: Ionization energy is defined as the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.
General equation of ionization energy is given by:
- If the outermost electron is loosely bound to the nucleus which means that the electron can be easily removed form an atom, it will require less amount of ionization energy.
- And if the outermost electron is tightly bound to the nucleus which means that the electron cannot be removed easily from an atom. And hence, it will require more ionization energy.
Hence, the given statement is true.
