Identify three of the seven common neurotransmitters and the functions of each. Then describe what each neurotransmitters controls or regulates in the body.
Answer:
Dopamine, Acetylcholine, Serotonin
Explanation:
Answer:
One common neurotransmitter is dopamine. It is an excitatory neurotransmitter that is involved in movement, learning, attention, and emotion. GABA is another common neurotransmitter, and it is a major inhibitory neurotransmitter. It is involved in anxiety, arousal, and sleep. Glutamate is a major excitatory neurotransmitter, and it is involved in learning and memory.
Acetylcholine: Serves as a messenger between each motor neuron and skeletal muscles, which accounts for its role in helping to control skeletal muscles.
Serotonin: Affects sleep, hunger, mood, and arousal; connected to aggression and abnormal behavior
Norepinephrine: Helps control arousal and alertness; helps in regulating mood
Endorphins: Major excitatory neurotransmitter; linked to memory and learning processes; released in response to pain and intense exercise

Which of the following is the correct equation for photosynthesis?
a.) CO2 + light + H2O --> O2 + Sugar
b.) CO2 + sugar + H2O --> O2 + light
c.) O2 + light + H2O --> CO2 + Sugar
d.) CO2 + O2 + H2O --> Light+ Sugar
Answer: a
Explanation: light is a energy sourse for the photosintesis and sugar is glucose wich is the food formd at the end of phothosintesis like oxigen..(etc..)....
The answer option with the correct equation for photosynthesis is: A. [tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]
Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs), transform light energy (sunlight) into chemical energy.
The correct equation for photosynthesis is given by this chemical equation:
[tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]
Hence, the necessary input for the process of photosynthesis to take place include the following:
Water ([tex]H_2O[/tex]).Sunlight (light energy).Carbon dioxide ([tex]CO_2[/tex]).
In conclusion, oxygen and sugar are end products (output) of photosynthesis rather being an input.

Explanation:
Use what you know about natural selection to fill in the blanks in the hypothesis. It should answer the lab question, “What is the effect of the type of food available on the frequency of different types of bird beaks?”
Hypothesis: If the type of food available changes, then…
…because…
Answer: The independent variable of the lab is the type of food that is available to the birds. The food type changes in a given environment, then the amount of each type of bird beak will changes as birds with beaks more suited to the available food will consume more successfully over time.
Explanation:
With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.
What are different types of bird beaks?There are many types of beaks in birds, some of these can be:
Crushing beak.Curved beak.Piercing and tearing beak.Birds of prey.Stickybeak.With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.
Thus, this is the hypothesis which support the given scenario.

Define natural selection and give Example with detailed explanations.
Answer:
Natural selection is when animals who are able to survive in their environment flourish, and those animals who aren't die out.
Explanation:
Lets say there were two rival animals, we can call them plantoids 1 and 2. These plantoids were both trying to out-survive each other. The problem is birds loved to eat them, so through evolution plantoids 1 began producing toxins, so when chewed on the bird would be poisoned. For awhile this worked, and the plantoids without it were dying off. Then plantoids 2 created a thorn on their heads, and were able to blend well. This worked well, and sadly for plantoids 1 the birds were able to eat them. The birds went through natural selection and those who were immune to the poison survived. Now these two plantoids are two completely different species, and they were once the same. In the end plantoids 2 survived because they were more adapted to the setting they lived in.

Answer:
This woman is likely to be hypothyroid.
Explanation:
The woman has symptoms that may be linked to hypothyroidism, which occurs when the thyroid produces little hormone
thyroid. This disease is more common in women than in men and can be very debilitating if not properly cared for.
The doctor who will assist the woman shown in the question above, should ask questions about what she is feeling and see if she has low immunity, weight gain (in addition to fluid retention), feeling cold, mental depression, menstrual irregularities and constipation .
Finally, the doctor must order a blood test to see if the levels of thyroid stimulating hormone (TSH) and thyroid hormone (T4) are adequate and thus to confirm or not the disease.
plz help!!!!!!!! A natural biological cooling process is sweating. Using your knowledge of endothermic and exothermic, explain why your body feels cooler when it sweats.
Answer and Explanation:
An exothermic reaction takes place when heat flows out of a system into its surroundings. ... When you sweat, the system – your body – cools down as perspiration evaporates from the skin and heat flows to the surrounding area. This means sweating is an exothermic reaction.

Jane has a beaker containing a clear solution. She adds a liquid pH indicator to the clear solution and observes that the solution changes to bright blue. The clear solution in the beaker must be a(an)
Answer: a (weak) acid
Explanation: the solutions are mostly neutral but the pH shown by the indicator as a bright blue means it is slightly acidic meaning the pH is between 6 and 7.6
As the solution turns bright blue on addition of indicator, the solution in beaker must be a weak base.
What is a base?
According to the Arrhenius concept, base is defined as a substance which yields hydroxyl ions on dissociation.These ions react with the hydrogen ions of acids to produce salt in an acid-base reaction.
Bases have a pH higher than seven as they yield hydroxyl ions on dissociation.They are soapy in touch and have a bitter taste.According to the Lowry-Bronsted concept, base is defined as a substance which accepts protons .Base react violently with acids to produce salts .Aqueous solutions of bases can be used to conduct electricity .They can also be used as indicators in acid-base titrations.
They are used in the manufacture of soaps,paper, bleaching powder.Calcium hydroxide ,a base is used to clean sulfur dioxide gas while magnesium hydroxide can be used as an antacid to cure acidity.

Describe the concept of natural selection. Be sure to include contributing scientists and their contributions.
Answer:
Natural selection is the process in which survival of the fittest, a concept by Charles Darwin suggests that animals adapt to better suit their needs. Those who survive are the "fittest" and breed children with the trait until the unfit die out. He saw this with the Galapagos finches. there used to be 1 kind of finch, now there are 14.
