<span>Heuristics and algorithms differ in terms of their level of indirection from the solution. That is the difference between an algorithm and a heuristic is subtle, and the two terms overlap each other. An algorithm gives you the instructions directly where as A heuristic tells you how to discover the instructions for yourself, or at least where to look for them.</span>
Answer:
exocytosis
Explanation:
“exo” means “out” or “outer”, and it appears that the red dots are moving outwards
Answer:
Explanation:
Afforestation simply refers to a campaign in favor of tree planting, against tree cutting in reserves or vegetation and the overall protection of the Forest reserve. Afforestation in the direct opposite of deforestation which is act of cutting down and destruction of forest trees. Trees are important part of our natural environment which plays economic, biological and chemical roles in the lives of the masses. Most notably, forest trees acts as carbon sink which in turn reduces depletion of the ozone layer. Even though their are economic derivatives in the cutting selling of forest planks for various purposes, tree planting culture must be legislated in other to avoid excessive use of forest reserves.
Answer:
Option A
Explanation:
As we all know, energy can never be created . Also it can never be destroyed. However, it can only be changed from one form to the other. In this case, when a pool ball is striked by a stick, the kinetic energy of stick is transferred to the ball along with release of sound. Sound is just another form of energy.
Now, when this ball strikes other balls, the same process is repeated i.e the ball strikes another ball and passes on its kinetic energy along with release of sound energy. Every time sound is released, the amount of kinetic energy transferring from one body to other reduces.
Option A is correct
Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.
In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.
Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.
