During the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending. The passive transport is seen in the cell too.
What is the importance of the different types of transportation?In the cell, different types of transport are seen, such as active transport and passive transport; in active transport, energy is used, while energy is not used in passive transport. The movement of molecules across the cell plasma membrane is important because it allows cells to get rid of unwanted molecules. Passive transport does not require energy, and many nonpolar small molecules and gases can cross the lipid plasma membrane barrier and go into and out of the cell while, in this passive transport process, they save the cell's energy.
Hence, during the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending.

What are two ways in which cells use the energy temporarily stored in ATP?
Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways
The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.
What is Active transport?
Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.
ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.

What are the products for a single pyruvate molecule in the Krebs Cycle?
Answer:
In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.

Predation is when a predator feeds on another organism, which is referred to as the predator's prey.
True
False
Answer:
True
Explanation:
Predation is another mechanism in which species interact with each other. Predation is when a predator organism feeds on another living organism or organisms, known as prey. The predator always lowers the prey's fitness. Also, a predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?
Answer:
A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.
The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.
Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.
Which structures are found in all cells? Select two options.
A. Chloroplasts
B. Lysosomes
C. Cell wall
D. Cytoplasm
E. Cell membrane
The structures found in all cells are cytoplasm and cell membrane, which are present in options D and E because these are the basic characteristics of the cell, whether unicellular or multicellular.
What is the significance of the cell cytoplasm and cell membrane?Cytoplasm and cell membrane are two essential structures present in all cells and maintain the cell's structural integrity while performing various cellular functions, while cytoplasm is the gel-like substance of the cell and contains the cell's organelles, enzymes, metabolic intermediates, etc.
Hence, the structures found in all cells are cytoplasm and cell membrane, which are present in options D and E because these are the basic characteristics of the cell, whether unicellular or multicellular.

Which of these statements concerning lipids is not true?
A. Lipids are substances that dissolve in nonpolar solvents.
B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated.
C. Fats, phospholipids, and steroids are lipids.
D. The building blocks of fats (triglycerides) are fatty acids and glycerol.
Answer:
B
Explanation:
Unsaturated fatty acids have double bonds. Fatty acids that contain only single covalent bonds between the carbon atoms are called saturated.
The statement: "B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated." is NOT TRUE.
Lipids include the following group of compounds:
FatsOilsPhospholipids SteroidsWaxesThe above compounds are nonpolar hydrocarbon compounds that are insoluble in water. This means they can hardly dissolve in water.
Fatty acids, which is an example of lipids, can either be saturated or unsaturated. If it is saturated, it means they contain only single covalent bond among the carbon atoms while it is unsaturated if a double bond exist in the chain of the molecule.
A fatty acid that contains only single covalent bonds cannot be called "unsaturated." It is rather "saturated."
Therefore, the statement concerning lipids that is not true is: B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated.
An example of a saturated fatty acid is shown in the attachment below:
