prokaryotic cells are smaller than eukaryotic cells. what is a plausible explanation?
Answer:
prokaryotic cells are smaller than eukaryotic cells because they have fewer organelles.
Explanation:
prokaryotic cells do not contain a nucleus, vacuoles, endoplasmic reticulum, mitochondria, Golgi apparatus, lysosomes, or peroxisomes, thus making them smaller than eukaryotic cells.

how does an electron transport chain lead to the generation of atp in the light-dependent reactions of photosynthesis?
Answer: How does an electron transport chain lead to the generation of ATP in the light-dependent reactions of photosynthesis? ... The electron transport chain directly absorbs light energy and transforms it into the chemical energy of ATP.
Explanation:
Help please! Q: Location Three: Select three events that you predict will be observed. If I explore two continental plates at a transform boundary, then I will observe:
A: earthquakes
B: faults
C: ocean formation
D: mountains
E: volcanoes
F: island chains
G: seafloor spreading
Answer:
Earthquakes, Faults, and Island chains.
Explanation:
There are three types of plate boundary such as Constructive, destructive and transform plate boundary. The primary landform in the Transform boundary are faults which is caused by the Earthquakes. Many transform boundary landforms are in the ocean floor which is responsible for the island formation. Fault is found due to the two process such as Ridge push and ridge pull. Transform boundary neither creates and nor destroys any land in the region.
Which example(s) of cell transport do/does not require chemical energy?
A.
Drops of blue food coloring are placed in water and spread throughout the water, turning it blue.
B.
A potato slice is placed in water and water molecules from inside the potato move into the surrounding water.
C.
both A and B
D.
neither A nor B
Answer:
C
Explanation:
Because osmosis(B) this is where water moves from a high concentration to a low concentration across a partially permiable membrane( No energy required). Whereas in diffusion (a) this is the net movement of particles from a region of a high concentration to a region of a low concentration. This stops when the region is evenly spread. (No energy is required)
The cell transport which takes place in food coloring, potato slice is concentration gradient. This type of cell transport does not need energy. Thus, the correct option is C.
What is Cell transport?
Cell transport is the transport of molecules through the cell membrane. Transport of substances through the membrane takes place through osmosis and diffusion.
The diffusion of substances can be active or passive on the basis of requirement of energy. The passive mode of transport does not require energy as the movement of substances occurs down the concentration gradient from high concentration to low concentration. Whereas, in active transport energy is required in the form of ATP as the transport occurs against the concentration gradient from low concentration to high concentration.
Therefore, the correct option is C.

why is the digestion of starch to glucose necessary
Answer: The fundamental sugar unit for carbs is usually glucose. To address your question, starch digestion is required because enzymes and transport molecules require tiny, regular molecules to work with, and glucose is the foundation of most carbohydrate metabolism.
Explanation:
Answer:
The molecule of starch is too large and complex to enter a cell and therefore, it cannot be ingested directly. It is important to break down the bigger molecules of starch into smaller and simpler molecules of glucose so as to perform the process of glycolysis.
Explanation:
The process of glycolysis happens at a cellular level where glucose molecules are further broken down and utilized as energy to carry on various other cellular processes. The process of glycolysis happens in two stages namely:Energy requiring stage:Step 1: Glucose phosphorylation where a molecule of phosphorus is added to the glucose ring.Step 2: Energy releasing phase where the molecule of glucose-6-phosphate is converted to fructose-6-phosphate. Step 3: involves the phosphofructokinase reaction where fructose-6-phosphate is converted into fructose1,6-biphosphate.Step 4: involves an enzyme aldolase which converts the FBP into 23 carbon isomers.Step 5: involves the formation of glyceraldehyde-3-phosphate.Energy releasing stage: It breaks down glyceraldehyde-3-phosphate to pyruvate releasing 4 ATP and 2 NADP for cellular processes.For more information:
