C.
30% thymine, 20% cytosine
D.
40% thymine, 10% cytosine#
Answer:
30% thymine, 20% cytosine
Explanation:
In a typical DNA double helix pyrimidine; Cytosine and thymine always pair with Purine ;Adenine and Guanine. This pairing ensure that the double helix of DNA is maintained by the presence of Hydrogen between these organic bases.
For correct pairing all adenine must pair with thymine,and all Cytosine with guanine.Therefore for this to occur if 30 % of adenine is present,the composition and number of thymine(30%) must be available.If this percentage is not available the pairing will not occur.
Like wise 20% Cytosine must be present because ,then same amount of Guanine molecule 20% in the DNA molecule. must be present Thus Guanine percentage is 20%.
This give a total of 100(60+40)
This based on the Erwin Chargaff stoichiometric ratio of 1:1 .This states that the percentage of adenine =thymine,and that of Guanine=Cytosine,in the DNA of living cells should be equal. Thus; [A]+[G]=[C]+[T]=1:1

What happens to carbon in plants when the plants die?(1 point)
The carbon is not released; it is lost.
The carbon will be released into the soil for use by the next generation.
The carbon is released into the air.
The carbon is released into the soil, but it is not used again.
Answer:
The carbon will be released into the soil for use by the next generation.
Explanation:
I finished the quiz and this was the correct answer.
When the plants die in that case the plants will die and the carbon from the body of the plants gets displaced in the soil. This is the end cycle of the nutrients of plants.
What is the location of carbon in plants ?It is the carbon compounds with the glucose containing the 6 number of carbons and the sugars containing total in 5 numbers of carbons.
As the plants gets the soil there body gets decomposed into the soil and later on the carbon that is absorbed from the atmosphere is given back to the soil and later on they together make the energy sources of carbon in the form of fossils which can be demonstrated later on as well.
And after plants get died, they get decayed by releasing carbon to atmosphere. The difference in the amount of carbon plants get absorbed and they do release is known as the net primary productivity. It is the direct measurement of the amount of how much plant matter is from the crops to the forests or ocean phytoplankton by the Earth produces.

How does carbon flow between photosynthesis and cellular respiration?
A. Photosynthesis produces carbon dioxide from glucose made by the process of
cellular respiration.
B. Cellular respiration produces carbon dioxide from glucose made by the process of
photosynthesis.
C. Photosynthesis produces carbon dioxide from ATP made by the process of cellular
respiration
D. Cellular respiration produces carbon dioxide from ATP made by the process of
photosynthesis.
Answer:
B. Cellular respiration produces carbon dioxide from glucose made by the process of
photosynthesis.
Explanation:
Photosynthesis is a process by which the autotrophic cells make food by absorbing and converting solar energy into chemical energy.
Cellular respiration is a process in which the oxygen molecules couple with food nutrients to generate energy, CO₂ and water.
The correct answer is:
Option B. Cellular respiration produces carbon dioxide from glucose made by the process of photosynthesis.
This can be explained as:
Photosynthesis uses the light energy from the sun to convert them into chemical energy.The reactants of photosynthesis are sunlight, carbon dioxide and water molecules and the products produced are glucose and oxygen molecules.The glucose produced by the process of photosynthesis is then utilized in cellular respiration to produce carbon dioxide.Therefore, cellular respiration utilizes the glucose produced from photosynthesis.

about exocytosis?
a. Help intake large material into the cell
b. Form of active transport
C. Occurs without help of cell organelle
d. It does not require energy
Answer:
B. Form of active transport
The statement that is true about exocytosis is that it is a form of active transport. That is option B.
Exocytosis is a cellular process where by materials especially waste products of metabolism or ions are moved from inside the cell to the outside of it.
An active transport is a process where by cells use energy to transport molecules across the cellular membrane.
There are different forms of active transport include:
EndocytosisexocytosisSodium Potassium Pump.Phagocytosis is the process by which cells transport large material into the, therefore Option A is False.
Golgi apparatus helps in exocytosis therefore option C is false.
Exocytosis requires energy, there option D is false
From the different forms of exocytosis listed above, exocytosis is a form of active transport because it makes use of energy.

Depending on the organism, the optimal pH for enolase to catalyze its reaction is between 6.5 and 8.0 . Describe how a pH below or above this range is likely to affect enolase and its catalytic ability.
Answer:
Enolase are enzymes, when a enzyme goes into a different ph level that is not used to, it will be denatures and will lose its catalytic ability.
Enolase are enzymes, when a enzyme goes into a different ph level that is not used to, it will be denatures and will lose its catalytic ability.
What are enzymes?Proteins called enzymes aid in accelerating our bodies' chemical reactions, or metabolism. Some compounds are created, while others are broken down. Enzymes are a part of all living things.
Enzymes are created by our bodies spontaneously. However, food and manufactured goods both contain enzymes.
The body contains tens of thousands of different enzymes. Every type of enzyme has a single function. For instance, the enzyme sucrase degrades the sugar sucrose. Lactose, a type of sugar included in milk products, is broken down by lactase.
Therefore, Enolase are enzymes, when a enzyme goes into a different ph level that is not used to, it will be denatures and will lose its catalytic ability.

This type of system does not interact with the environment around it. It recycles all of the mass on its own.
A. No system
B. Open system
C. Isolated system
D. Closed system
Answer:
C. Isolated system
Explanation:
The question above is related to the the topic, "Thermodynamics."
Thermodynamics refers to how energy is being transferred among molecules. This study focuses on the "system" and the "surroundings/environment"
There are actually three types of systems (open, closed and isolated). When it comes to "isolated system," such system doesn't interact with the surroundings. This means that, it is incapable of exchanging energy or matter with its environment. This means that neither mass nor energy will be able to enter it; thus, it recycles all of the mass on its own.
