Describe the process of action potential conduction and neurotransmission from one neuron to another, both electrically (including saltatory conduction) and chemically. Describe how a cell fires an action potential and be sure to address which structures are involved in neurotransmission. Discuss reuptake and enzymatic degradation (breakdown) in the context of the appropriate neurotransmitters.
Answer:
neurons are able to communicate through electrical impulses for example when a stimulus is detected the receptor cells transfer electrical impulses to the sensory neurons which is passed onto the relay neurons in the central nervous system and relayed to the motor neurons. the motor neurons travel with the electrical impulses which are transferred to the effectors to cause a response. However neurons travel and commu icate through synapses
Design a controlled experiment to test the effect of water temperature on goldfish. be sure to include your hypothesis, independent variable, dependent variable as well as experimental group and control group.
Answer:
In this experiment, indepedent variable will be temperature and dependent variable will be the respiratory rate of goldfish. Temperature affects the respiratory rate of goldfish, as it's respiratory rate decreases with decrease in temperature of water, the experiment is as follows:
Take two glass containers filled with water A and B and put one goldfish in each container.Measure the temperature of the water using a thermometer.Count mouth movement of both the fishes in certain time.Now put some ice in container B that will decrease the temperature of water and measure the temperature again.Now count the mouth movement of both the fishes for the same time it was counted earlier.The result will be that respiratory rate of goldfish decreases with the decrease in temperature in container B in comparison to container A goldfish.
An experiment meant to determine the cause of an effect, the effect is the independent variable, while the cause is the dependent variable
A controlled experiment to test the effect of water temperature on goldfish is designed as follows:
The experimental group are: The gold fish in a glass Jar X filled with fresh water and with the lid left open (the treatment of temperature reduction is applied to the experimental group)
The control group are: A second gold fish (selected at random) of the same size, in another glass jar Y filled to the same level with fresh water collected from the same source of the first gold fish
Independent variable: The independent variable is the temperature of the water which will be varied by placing ice cube gradually into the glass jar B
Dependent variable: The number times the gold fish gulp air by rising to the surface, and or the number of time goldfish opens its mouth, which indicates that the goldfish is breathing
The hypothesis: The breath rate of goldfish decreases with decrease in temperature because the goldfish metabolic rate decreases and the water holds more dissolved air and therefore oxygen at a reduced temperature
The Experiment Design:
The experiment is conducted by measuring the initial temperature and breathing rate of both fishes
The temperature of the fresh water in jar X is decreased gradually by adding ice cubes and recording the temperature and breathing rate of the goldfish
A similar experiment from an online source (Maryland School improvement website) the following results where obtained
[tex]\begin{array}{|c|cc|} \underline {Breathing \ rate}&&\underline {Water \ Temperature } \\&&\\ (Dependent \ Variable)&&(Independent \ Variable)\ \\&&\\103&&78.8 ^{\circ}F\\78&&68^{\circ}F\\55&&57.2^{\circ}F\\28&&46.4^{\circ}F\\4&&35.6^{\circ}F\end{array}\right][/tex]
From the experiment, it can be seen that the in the experimental group dependent variable, which is the breathing rate of the goldfish reduces as the temperature which is the dependent variable is reduced

In a 1973 essay with the same name, geneticist Theodosius Dobzhansky made famous the idea that nothing in biology makes sense except in the light of evolution. From a careful reading of The Serengeti Rules, one could also argue that nothing in biology makes sense except in the light of regulation. Do you agree or disagree with this claim
I agree with this claim because organisms interact with one another in an ecosystem, thereby regulating population sizes in the community.
The Serengeti Rules is a documentary film based on biologist Sean B. Carroll's book (2017). This book explains the balanced functioning of an ecosystem by exploring the discoveries of five pioneering scientists: Mary Power, Bob Paine, Tony Sinclair, John Terborgh, and Jim Estes.
The term 'Serengeti rules' is due to many of these rules were obtained by studying natural populations in the Serengeti National Park (Tanzania).
These rules are a set of simple ecological rules of nature that indicate how ecosystems work.
The Serengeti rules explain how organisms interact with one another in the ecosystem, thereby regulating population sizes in the community.
Some key concepts of the Serengeti rules are as follow: Keynote species is a type of species whose activities govern the wellbeing of other species in the ecosystem. A trophic cascade is a phenomenon by which species impact other species even when they do not directly interact with each other. Downgrading refers to cascading effect of the removal of a species at the top of a food web (e.g., predators)

an advertisement on tv claims children grow faster with the use of vitamin gro. vitamin gro is a 25mg pill taken twice a day. the viewer has little knowledge about how children grow, but he knows that children need a complete diet and a good exercise routine. he decided to put the commercial to the test. the viewer uses his 6 nieces who are the same age to conduct the experiments. to make the experiment easier he uses his six nieces using labels such as child 1, child 2 and so on. he records their height every 3 days for 7 days. What are the variables?
Answer:
Independent variable - vitamin gro and exercise routine.
Dependent variable - growth of children or nieces.
Explanation:
There are two variables present in an experiment called dependent and independent variables.
Independent variables are those variables which can be controlled in an experiment and dependent variables are those variables which are measured in the experiment under the influence of the independent variable.
In the given experiment, the independent variable will be vitamin gro and exercise routine and the dependent variable is the growth of children or nieces because vitamin gro and exercise routine can be controlled and growth of children is dependent on vitamin gro and exercise routine.
HEEELLLPPP PLSS!!! Compare and contrast open, closed, and isolated systems. Be sure to discuss the exchange of energy and exchange of matter, and provide at least one example of each.
Answer:
See the answer below
Explanation:
An open system is a type of thermodynamic system in which energy and matter are being exchanged between the system and the surrounding. It is like boiling soup in an open pot. The opening allows for the addition of materials (matters) into the soup and energy is exchanged through the heating. A good example is found in biological organisms. They consume matters and exchange energy with the environment by carrying out work.
A closed system is a type of system in which there is no exchange of matter between it and the environment. However, there is an exchange of energy. It is like boiling water in a closed pot. Nothing can be added into the pot due to the closure but energy can be transferred through the heating of the pot.
An isolated system allows for neither energy nor matter exchange with the surrounding. It is like a closed food warmer that allows for nothing to enter or leaves it.
Answer: Open systems are energy that can be transferred between the system and its surroundings. Close systems are systems that do not transferred to its surroundings. Isolated systems is a thermodynamic system which cannot exchange either energy or matter from outside its boundaries of the system.
