Answer is c. Natural gas.
Natural gas is a fossil fuel in liquid form that can be used as an energy source. It is found in subterranean reservoirs, often near oil deposits. It is non-renewable energy source. It takes very long time to renew. Natural gas is less pollutant as compared to coal and petroleum because when it's burned, it releases 25 % fewer greenhouse gases and pollutants. hydroelectric power, solar power and nuclear energy are renewable sources.
Answer:
Photosynthesis
Explanation:
Chloroplasts are involved in both types of photosynthesis
Answer:
First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.
Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.
In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).
Answer:
In this case, it is likely that the polypeptide chain assumed an alpha helix configuration because the lipid bilayer did not have beta-barrel proteins.
Explanation:
A polypeptide chain is naturally polar, however, a lipid bilayer is naturally non-polar. This makes it difficult and even prevents the polypeptide chain from crossing a lipid bilayer, since the composition of these two elements does not allow them to mix. In that case, the polypeptide chain has two options to take to successfully cross the lipid bilayer.
The first option that the polypeptide chain has is to allow the creation of twisted beta sheets in the shape of a closed barrel in its structure. This only works if the lipid bilayer has beta barrel proteins in its composition to act as a transport channel for the polypeptide chain. However, few lipid layers have this protein.
Most likely, the polypeptide chain assumes an alpha helix conformation to cross lipid bilayers that do not have beta-barrel proteins. By assuming the beta conformation, the polypeptide chain reinforces the hydrogen bonds present in its composition, allowing it to cross the lipid bilayer without having its conformation and structure disassembled.
Answer:
The correct answer is carbohydrate chain.
Explanation:
Plasma membrane contain three types of protein a peripheral protein b transmembrane protein and c GPI anchored protein.
Some membrane protein basically peripheral proteins contain oligosaccharide chain arranged towards the extracellular region of the plasma membrane with respect to the surface of that glycoprotein.
The oligosaccharide chain of glycoprotein play an important role in to identify signals from outside the cell.These signals may include the entry of virus particles inside our body,protein targeting etc.
