Answer:
C.
Explanation:
Lipids and proteins are both types of macromolecules. Macromolecules are molecules made up of more than one atom.
It would be osmosis because osmosis is the diffusion of water through a selective membrane.
Answer: Option A .
In a coil by Hydrogen bonding.
Explanation:
B - pleated sheet secondary structure of protein is a regular element of secondary protein structure which consist of beta strands. In B pleated sheet, two or more segments or strands of polypeptide chain lie at the side of each other to form sheet which is held by Hydrogen bonding. The G in B pleated sheet form a coil and are held by Hydrogen bonding. This bond is formed by carbonyl and amino acid group.
The correct option is B.
In the ecosystem, energy flows from one trophic level to the other. The first trophic level is that of the producers which use the energy of the sun to produce their own food. Out of the energy obtained from the sun by the producers only about 3% of it is converted into food products. The second trophic level is made up of the herbivores and the omnivores which eat the plant. Only about 10% of the energy from the plant is transferred to the animals in the second trophic level. These second trophic level animals will also transfer about 10% of the energy they obtain to the animals in the third trophic level when they are eaten. Thus, it can be seen that the energy that is transferred in the ecosystem is gradually reducing from one trophic level to another.
The answer is rice, wheat, and corn.
Croplands, rangelands and pastures, and fisheries and aquaculture provide an important supply of world's food. Nearly 80% of the world's food comes from croplands. People can eat about 50,000 plant species, but only 14 of them supply the majority of world's food. Of those 14, only three grains, and those are rice, wheat, and corn, are consumed by about two-thirds of the world's human population.
