LO 5-3 How does the nervous
system communicate electrica
and chemical messages from
one part to another?
Final answer:
The nervous system communicates through an electrochemical process, where electrical signals within neurons are combined with chemical signals via neurotransmitters across synapses, enabling efficient transmission of messages throughout the body.
Explanation:
How the Nervous System Communicates
The nervous system uses an intricate electrochemical process to communicate messages across different parts of the body. This complex process involves both electrical signals within neurons and chemical messengers known as neurotransmitters to transmit information between neurons. Let's break this process down into understandable parts:
Electrical Signaling: Within a neuron, an electrical signal travels from the dendrites, through the cell body (soma), and along the axon to the nerve terminal.Chemical Signaling: Once the electrical signal reaches the axon's end, it triggers the release of neurotransmitters into the synapse, the gap between neurons. These chemical messengers then bind to receptor sites on the adjacent neuron, effectively transmitting the signal across the gap.This combination of electrical and chemical signaling allows for fast and efficient communication throughout the nervous system, enabling response to stimuli and coordination of activities.Through this powerful electrochemical mechanism, our nervous system controls everything from simple reflexes to complex thoughts and emotions.

which scientific investigation does not include dependent and independent variable?
1.observing and counting bird populations
2.studying the effect of temperature on bacterial reproduction rates
3.investigating the effect of mass on the speed at which an object falls
4.testing a model car's air flow resistance at different wind speeds in a wind tunnel
The scientific investigation without dependent and independent variables is observing and counting bird populations, which is an observational study and not a controlled experiment.
Explanation:The scientific investigation that does not include dependent and independent variables is observing and counting bird populations, which is an example of an observational study. In this type of investigation, researchers are simply making observations without manipulating any factor. Therefore, there isn't an independent variable being altered to see its effect on a dependent variable. However, in the other three options provided, there is a clear manipulation of one variable (the independent variable) to see its effect on another variable (the dependent variable), which classifies them as controlled experiments.
For example, in studying the effect of temperature on bacterial reproduction rates, temperature is the independent variable, and the bacterial reproduction rate is the dependent variable. Likewise, when investigating the effect of mass on the speed at which an object falls, mass is the independent variable, and the falling speed is the dependent variable. In testing a model car's air flow resistance at different wind speeds in a wind tunnel, wind speed is the independent variable, and air flow resistance is the dependent variable.

Explanation:
Without the precise diagram, Label A might refer to the central atom or the atomic number, and Label B could refer to surrounding atoms or the mass number. These labels generally correspond to specific parts of an atom or molecule, which include the nucleus and electrons in the context of atomic structure.
Explanation:The question appears to be related to the structure of the atom and its components. Although the exact diagram for Label A and Label B is not provided, based on the provided references, we can infer that Label A may refer to the central atom in a molecule, while Label B could be addressing the atoms surrounding the central atom. Moreover, in the context of atomic structure, Label A might signify the atomic number, and Label B might represent the mass number, as indicated in reference to Figure 1.8.3 which states that the atom's symbol includes the atomic number and mass number.
In atomic physics, key parts of the atom typically include the nucleus (comprised of protons and neutrons) and the electrons that orbit around it. The nucleus is the dense center of the atom, containing most of the atom's mass, while the electrons are subatomic particles with a negative charge that move around the nucleus in what are known as electron clouds or shells.
If the diagram provided to the student was similar to the one described in the references, Label A and Label B would likely be pointing to specific parts of the atom or to elements in a compound or molecule depending on the context given within the diagram.

Because plants don’t have interior or exterior skeletons they rely on their cells walls to give them support . Did you see evidence of the cells structure in plants ? How was it different from animal cells
Answer:
Plant cells have cell walls and this is how they differ from animal cells because animal cells do not have cell walls. Animals don't need cell walls because they have skeletons that help stabilize their bodies. The cell wall provides structure and strength to the cell. I saw evidence once when I was in a biology class.
I did see evidence of the cell structure in plants. Plant cells have a cell wall, which is a rigid structure that surrounds the cell membrane.
How are plant and animal cells different ?The cell wall is made up of cellulose, a complex carbohydrate that gives plants their strength and rigidity. Animal cells do not have cell walls. The cell wall provides support and protection for the cell.
Plant cells have chloroplasts, which are organelles that contain chlorophyll. Chlorophyll is a green pigment that helps plants to photosynthesize. Animal cells do not have chloroplasts. Plant cells have a large central vacuole, which stores water and other nutrients. Animal cells do not have a central vacuole.
