I dont know if have this but... i have this questio and it is c
It is a true fact that over tillage harm the soil. Over tillage actually increases the intake water capacity of the soil. As the intake capacity of the soil increases, there is every chance that the soil will become compacted. This happens as the broken up elements of the soil start coming together and results in compaction.
Answer:
A disadvantage of a non renewable resource is that it runs out.
Explanation:
If people become reliant on a non-renewable resource then when it runs out they are screwed.
Answer:
Visibility
Explanation:
The depth at which an Emperor Penguin can dive is dependent on the extent to which sunlight can penetrate the ice water according to research. The extent of at which light can penetrate the ice water is also dependent on the degree of ice cover on the ocean. As a result of this, <em>as the depth of dive of an Emperor Penguin increases, visibility also decreases as light penetration reduces. In order words, lack of sunlight would reduce visibility as the diving depth of the Emperor Penguin increases.</em> That is why most deep dives have been found to occur in spring time when light penetration is high as a result of sunlight availability.
Answer:
NH2 group combines with COOH group to form CONH group after releasing water
Explanation:
A peptide bond is formed between two R groups of amino acids by eliminating a molecule of water. If two amino acid joins, then a dipeptide link is formed. When three amino acid joins, then a tripeptide link is formed. And in case when many amino acid joins, then a polypeptide link is formed. A protein chain usually has several amino acid residues ranging from 50 to 2000 in numbers. Since a polypeptide chain is formed after the removal of water , it is known as amino acid residues.
Generally , NH2 group combines with COOH group to form CONH group after releasing water
