Wind affects plant growth, reproduction, distribution, death, and ultimately plant evolution. Some of the effects depend on the air boundary layers next to the aerial parts of a plant, across which gas and heat exchanges with the environment occur.
<h2>The rotational motion of the forearm</h2>
Explanation:
- The two large bones of the forearm, one being the Ulna and the other is radial bone or radius.
- The Radius is larger in size than the Ulna.
- Radius is prism shaped, little curved longitudinally long bone.
- The part of two joints known as elbow and wrist comprised the Radius.
- Radius link with the capitulum of the humerus at the elbow region.
- Radius forms a joint at the wrist region with the ulna bone.
Answer:
b. at each step, energy is lost from the system as a result of keeping the organisms alive
Explanation:
Generally Ecological pyramids helps to visualise the structure of Ecosystem.Its diagrammatically showed the relative amounts of numbers of organisms ,their energy, and the amount of energy that is converted in living tissue as usable mass (biomass) at different tropic levels.
Basically, large amount of energy is lost as energy flow from one tropic level to another in an ecosystem. This can be explained with the second law of thermodynamics;<u> </u><u>which states that in the conversion of energy from one form to another in a system, there is always a tendency towards disorderliness</u><u>.</u>That is the entropy changes of the universe can never be negative.Relatively in a biological system, this means that energy is lost in metabolic process( glycolysis, chemeosmosis, assimilation, growth .......) as heat, as organisms at one tropic level is consumed by another at the next level, from the base to the peak of these pyramids.
The amount of energy transfer efficiency among the two successive tropic levels is obtained by <u>dividing the energy transfer at present tropic level</u> with<u> the energy transfer at previous tropic levels</u> and<u> mutiply the results by 100%</u> . This known as Tropic level transfer efficiency(TLTE) .
The lower energy efficiency between successful present and previous tropic levels in these pyramids accounts for the similarities.
Answer: dietary fiber
Explanation:
The dietary fibers can be defined as those nutrients in the diet which cannot be digested by the gastrointestinal enzymes and the minerals from them are not absorbed by the body. These keep the bowel full after food intake for long. These prevent disease like diabetes as reduces the need for consumption of more food, heart disease and constipation. The fruits, vegetable, legumes, fibers are the sources of dietary fibers.
Answer:
Cell wall: plant cells have a cellulosic cell wall, which is absent in the case of animal cells. The plasma membrane serves as the outermost boundary for an animal cell
