An excitatory postsynaptic potential (EPSP)

Biology
1 answer:
ella [17]3 years ago
3 0

Answer: A is the correct answer.

Explanation: If it is an EPSP, it increases the likelihood of an action potential. Therefore only A and C make sense. To fire an action potential, the neuron has to depolarize; therefore A is the correct answer.

Explain ONE similarity and ONE difference between water borne and water washed diseases ​
eimsori [14]
Water-borne diseases, including cholera, typhoid, and dysentery, are caused by drinking water containing infectious viruses or bacteria, which often come from human or animal waste. Water-washed diseases, such as skin and eye infections, are caused by lack of clean water for washing.

Please help I can’t figure this out
Ilia_Sergeevich [38]

Answer:

Photosynthesis is the process in which cells use carbon dioxide and water to make glucose in the presence of sunlight.

Respiration is the process in which glucose molecules are utilized to release energy in the form of ATP.

Explanation:

Ans1- Respiration in cells occurs in mitochondria.  Cells gain energy in the form of ATP. Conversion of glucose in the form of ATP is known as cellular respiration.

Cellular respiration can take place either in presence of oxygen(aerobic respiration) or in absence of oxygen(anaerobic respiration ).

Before entering into cellular respiration glucose molecule has to be converted into pyruvic acid. This process in known as GLYCOLYSIS.

<em><u>Anaerobic respiration</u></em> occurs in mitochondria when oxygen is not present. It is known as fermentation.It is not effective process to produce ATP from glucose as in this process only 4 ATP can be released.  

<u><em>Aerobic respiration</em></u> occurs in mitochondria in presence of oxygen.  This is effective pathway to gain ATP as it releases 36 ATP from 1 glucose molecule.

Ans2- All cells which has photosynthetic pigments are able to use photosynthesis. Example- Blue green algae, cynobacteria etc.

Ans3- We can see different shades of green colors of plants and leaves because of different types of chlorophyll present in plant. Chlorophyll are of 6 types in plant. Their types are based on the lights they absorb. Two main types of chlorophylls are chl a and chl b.

Ans4- Both plant and animal cells have mitochondria. In plant also they need energy. To get ATP from breakdown of glucose respiration is occur in plant also.

Ans5-In photosynthesis glucose is formed from water and carbon di oxide. 6 carbon dioxide and 6 molecules of water are used to make 1 molecule of glucose. Water and carbon di oxide are reactant in this process.

Ans6 -  Cells without oxygen can burn glucose to release energy. This process is known as Anerobic respiration/ fermentation. But the outcome of energy is lower than aerobic respiration. ( ANS1)

Ans7- In the process of photosynthesis reactants are water and carbon di oxide. Oxygen produced released in the form of gas along  with carbon di oxide.

Ans8- The enzymatic reaction of respiration occurs in mitochondria. Krebs cycle occurs in the matrix of mitochondria.( ETC electron transport chain) to release ATP occurs in cristae of inner membrane of  mitochondria.

Ans9- Plants make glucose through photosynthesis . In  presence of sunlight plants use carbon dioxide and water to make sugar.

Harrizon [31]
The appropriate response is Monosodium Glutamate. Unadulterated MSG is accounted for to not have a wonderful taste to the point that it is joined with an exquisite fragrance. The fundamental tactile capacity of MSG is credited to its capacity to upgrade flavorful taste-dynamic mixes when included the best possible concentration. The ideal fixation differs by nourishment; in clear soup, the joy score quickly falls with the expansion of more than one gram of MSG for each 100 mL.

Adult tickets for the school musical sold for $3.50 and student tickets sold for $2.50. On a given night, 321 tickets were sold
nalin [4]

Answer:

total amount spent on student ticket = 186($2.5)=$465.00,

Total amount spent on adult tickets = 135($3.5)=$472.50

Explanation:

cost total = student ticket price (x) + adult ticket price (321 - x)

$937.50 = (2.5)(x) + (3.5)(321 - x)

$937.50 = 2.5x + 1123.5 - 3.5x

x = 186, therefore 186 student tickets sold,  

(321-x) = 321-186 = 135, therefore 135 adult tickets were sold.

total amount spent on student ticket = 186($2.5)=$465.00,

Total amount spent on adult tickets = 135($3.5)=$472.50

So the total amount spent on tickets was  

$472.50 + $465.00 = $937.50
