The driving force of photosynthesis is SUNLIGHT ENERGY.
Green plants have the capacity to manufacture their own foods, through the process of photosynthesis, as the result of chlorophyll which their cells contain. The chlorophyll has the ability to trap the energy from the sun and use it to drive the process of photosynthesis. The major function of sunlight in photosynthesis is to break down the water molecules and turn them into high energy electrons that are capable of forming ATP molecules.
Answer:
Adaptive Radiation
Explanation:
Adaptive radiation refers to the process of diversification of ancestral line into different forms that occupy diverse ecological niche. The ancestral seed eating stock of Darwin’s finches diversified according to different types of food (plants, seeds, insects, cactus etc) available. They developed type of beak adapted to that food. The geographical isolation led reproductive isolation. Hence, many species of finches on the Galápagos Islands exhibit "adaptive radiation".
The unpredicted changes in the genetic material of chromosomes in a cell is known as Mutation. Mutations are the changes in gene caused by mutagens. Thus, the correct option is A.
Mutation can be defined as any change in the DNA sequence of a cell. These may be caused by mistakes during the cell division, or may be caused by exposure to DNA-damaging agents in the environment which are called Mutagens. Mutations can be harmful, beneficial, or have no effect.
Mutations can affect an organism by changing the phenotype or it can impact the way DNA of an organism codes the genetic information. When mutations occur in an organism they can cause termination of an organism or can be partially lethal.
Therefore, the correct option is A.

Answer:
Glycolysis.
Explanation:
Aerobic respiration involves complete breakdown of glucose molecule in the presence of oxygen to release 36 molecules of ATP. On the other hand, anaerobic respiration involves partial breakdown of glucose molecule, when oxygen is absent to release only two molecules of ATP.
Glycolysis is a universal process as it is common in both aerobic and anaerobic respiration. It does not require oxygen and can occur in both presence or absence of oxygen. Glycolysis forms two [pyruvate molecules, two ATP molecules. along with two NADH molecules from one glucose molecule.
Thus, the correct answer is 'glycolysis.'
Both aerobic and anaerobic respiration involve the breakdown of glucose for energy, but aerobic respiration requires oxygen and produces carbon dioxide and water, while anaerobic respiration occurs without oxygen and produces either ethanol or lactic acid.
Aerobic respiration and anaerobic respiration are two different processes that cells use to generate energy, but they share some similarities. Both processes involve the breakdown of glucose molecules to release energy in the form of ATP (adenosine triphosphate). Additionally, both processes occur in the cytoplasm of cells and involve the initial step of glycolysis, where glucose is converted into pyruvate.
However, the key difference between aerobic and anaerobic respiration lies in the final steps. Aerobic respiration requires oxygen and proceeds with the conversion of pyruvate into carbon dioxide and water through the Krebs cycle and the electron transport chain in the mitochondria. In contrast, anaerobic respiration occurs in the absence of oxygen and follows either alcoholic fermentation or lactic acid fermentation, where pyruvate is converted into either ethanol or lactic acid, respectively.

Answer:
The organelle responsible for converting energy from food into a form the cell can use is the mitochondrion.
The organelle responsible for converting energy from food into a form the cell can use is the mitochondrion.
Mitochondria are often referred to as the "powerhouses" of the cell because they produce the energy currency of the cell, called adenosine triphosphate (ATP). This process is called cellular respiration.
Here's how the mitochondria convert energy from food into ATP:
1. The process starts in the cytoplasm of the cell, where glucose molecules are broken down through a process called glycolysis. This step produces a small amount of ATP.
2. The remaining breakdown products from glycolysis are transported into the mitochondria.
3. Inside the mitochondria, these products undergo further breakdown through a series of chemical reactions in a process called the Krebs cycle, also known as the citric acid cycle. This step releases carbon dioxide and transfers energy-rich electrons to carrier molecules.
4. The carrier molecules transfer the electrons to the electron transport chain, located in the inner membrane of the mitochondria. This chain consists of a series of protein complexes that pass the electrons along, releasing energy in the process.
5. As the electrons move through the electron transport chain, the energy released is used to pump protons (hydrogen ions) from the inner compartment of the mitochondria to the outer compartment, creating an electrochemical gradient.
6. The electrochemical gradient drives the synthesis of ATP through a process called oxidative phosphorylation. ATP synthase, an enzyme embedded in the inner membrane, uses the energy from the electrochemical gradient to convert adenosine diphosphate (ADP) and inorganic phosphate (Pi) into ATP.
Overall, the mitochondria play a crucial role in converting the energy stored in food molecules into ATP, which the cell can then use for various cellular processes.
