Answer: There are two categories of cross membrane transport, active and passive. While active transport requires energy, passive transport relies on concentration differences inside and outside of the membrane. With films that cover the outermost membrane of the fruit (the skin), this concentration gradient can be removed or slowed so membrane transport is also slowed and as a result, the fruit stays fresh longer. A good analogy for this is considering evaporation in an open jar on a hot day versus if there was a lid on the jar. Both jars would be in the same conditions, but the jar with the lid would retain more water.
Explanation: have a great day:)

Explanation:
Autotrophs are organisms that have the capacity to manufacture their foods from freely available inorganic products. There are two types of autotrophs
1. The photosynthetic autotrophs: these are green plants and blue-green algae that possess chlorophyll. The chlorophyll is used to trap radiation from the sun in the presence of water and carbon dioxide to manufacture carbohydrates which serve as their primary foods.

2. The chemosynthetic autotrophs: these are usually bacteria that make use of energy from inorganic chemicals (such as hydrogen sulphide, iron sulphide, etc) to reduce carbon dioxide and produce carbohydrates in the process.

<u>Photosynthesis is quantitatively more important to life on earth because green plants form the base of several food chains.</u> The energy locked in the carbohydrate produced during photosynthesis is important for other lives in the ecosystem and this is passed on through the various levels in the food chain. Also, the by-product of photosynthesis, the oxygen, is important for the survival of most life on earth who depends on oxygen for respiration. Chemosynthesis only occur in habitats where the radiant energy of the sun is lacking, such as hydrothermal vents.
The answer is B) DNA in the nucleus.
The original code for all protein synthesis originates in the nucleus of the cell, in the form of DNA. From here it is transcribed onto mRNA to be transported to the ribosome through the cytoplasm.
Answer:
Explanation:
The flow of matter is connecting to all of the subjects involved. Several animals benefit off of the plants, then their predators benefit off of them, and so on. If even one of the factors of this food web were to go extinct, the entire thing would be messed up.
