Chemical changes occur when bonds are broken and/or formed between molecules or atoms. This means that one substance with a certain set of properties (such as melting point, color, taste, etc) is turned into a different substance with different properties. ... One good example of a chemical change is burning a candle.

Black_prince [1.1K]

Answer:

<h2>a.  1000 X 2^8</h2>

Explanation:

As given;

Initial population of bacteria= 1000;

Log phase growth is exponential phase, period in which bacteria gets double.

Generation time= 15 minutes;

it means, bacteria get double in every 15 minute,

so after 2 hours, bacteria will have 8 generation times;

so the final generation of bacteria is =1000 X 2^8.

Final bacterial generation after two hours = 256,000(1000 X 2^8)

What is the pathway of information through a neuron?
garik1379 [7]

Answer:

The pathway of information through the neuron is based in the connection of axons with other neurons, favoring the conduction of information from one place to another of the nervous system. The way in which a neuron communicates with another, with a receptor or an effector is called synapse.

Explanation:

Neurons are the specialized cells that allow the function of the nervous system, given by the transmission of information in the form of nerve impulses. The way in which information is transmitted by neurons depends on the connection that exists between neurons, by their axons and dendrites, or between enurons and specialized structures such as receptors and effectors.

When a stimulus reaches a receptor, it connects with the neuron that carries the information by afferent pathway to the central nervous system. Once the information is processed, a response is elaborated that travels through the neurons by efferent pathway to an effector cell.

Synapses are simply the connection that exists between neurons, through their axons, or from these cells to the receptor or effector structures. Synapses are located between one neuronal axon and another, or between axons and receptors or effectors, and occur through electrical signals or chemical mediators called neurotransmitters.
