12. During the process of photosynthesis, energy from the Sun is converted into A. chemical energy in the bonds of inorganic molecules B. chemical energy in the bonds of organic molecules C. enzymes used to produce inorganic molecules D. enzymes used to produce organic molecules
Eliminate and explain pls
Answer:
Explanation:
A. Inorganic molecules are rarely present in the human body, and the products of photosynthesis only contain one inorganic molecule (a molecule without carbon), [tex]O_2[/tex].
B. This is correct because when looking at the photosynthesis equation you have [tex]H_2O[/tex] + [tex]CO_2[/tex] + Sunlight = [tex]C_6H_{12} O_6[/tex] + [tex]O_2[/tex] Now illustrating this conversion, the [tex]O_2[/tex] Was made from the breaking of the bonds, so no new bonding was formed, this is the only inorganic molecule. The organic molecule, glucose, or the C6H12O6, was made combining the ingredients H2O and CO2. In order to combine the components used to make the glucose, the energy from the sun helps with the exchange of electrons and facilitates the bonding to make the organic molecule glucose.
C. Sun energy can not be converted into energy used to create enzymes
D. Same as C

Plants using the CAM pathway occur in many locations but are most common in very arid locations, such as deserts. What deserts occur in North America and where are these deserts located?
The desert that occurs in North America is the Great Basin Desert and it is located at Nevada of North America.
CAM pathway, which is also called Crassulacean Acid Metabolism, is a pathway that involves carbon fixation that occurs in plants growing in arid areas.
With this pathway these plants are able to photosynthesize during the day, but only exchange gases at night.
An arid habitat is an environment that is characterized by extreme lack of water, example is the desert.
In North America, the desert that occurs there is the Great Basin Desert. It spreads into different states which include:
NevadaWestern Utah, Eastern California, andIdaho.But the major part of Nevada is occupied by the Great Basin Desert.

Which activity would you do to find out presence of moisture in soil sample? Describe it with a diagram
You could calculate the moisture content of the soil by subtracting the weight of the dry soil from the weight of the moist soil, and then divide by the weight of the dry soil.
specific amino acids are attached to trna molecules by:
Answer: The energy of ATP hydrolysis is used to attach each amino acid to its tRNA molecule in a high-energy linkage. The amino acid is first activated through the linkage of its carboxyl group directly to AMP forming an adenylated amino acid; this linkage is driven by the hydrolysis of the ATP molecule that donates the AMP.

3. A strain of cells undergoes a mutation that increases the permeability of the inner
mitochondrial membrane to hydrogen ions.
a) What effect would you expect this mutation to have on the process of cellular
respiration? 12
b) Assuming the mutant cells can survive, how might the metabolic requirements of
these cells differ from those of a non-mutant strain of the same variety? 12
A mutation that involves the permeability of the inner mitochondrial membrane to protons (H+) will affect the amount of ATP. If mutant cells can survive, then they will need more energy to create a suitable gradient.
Cellular respiration is a series of metabolic reactions by which aerobic cells can generate energy in the form of ATP by using the chemical energy stored in the foods.
Cellular respiration can be divided into three sequential stages: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.
During oxidative phosphorylation, the transport of electrons across the inner mitochondrial membrane is coupled to the generation of an electrochemical proton (H+) gradient, which is then used to generate ATP by means of a protein complex known as ATP synthase.

Why is it that cancer does not form every time there is a mistake during the cell cycle?
Answer:
Cells will actually kill themselves through a process called apoptosis, or it will be attacked and killed so it doesn’t spread. For example, when you are exposed to the sun for a long period of time, the solar radiation can mess with your skin cells. That’s why you get sunburned: the cells dry up and fall off. Otherwise, you could get skin cancer
The reason why cancers does not form every time there is a mistake during the cell cycle is explained below:
The following information should be considered:

Which of the following is the source of the carbon found in glucose molecules?
Answer:
Carbon dioxide
Explanation:
When the plant makes the glucose molecule, it gets the carbon and oxygen atoms it needs from carbon dioxide, which it takes from the air. Carbon dioxide doesn't have any hydrogen in it, though, so the plant must use another source for hydrogen. The source that it uses is water
