Answer:

Regulatory sites e.g enhancers and silencers

Explanation:

Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.

Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.

Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.

mestny [16]
There should not be any changes in the gene pool.

In Hardy-Weinberg equilibrium, the gene pool should have a constant rate. The equilibrium can be achieved if there is no factor that favors one gene more than the others. Since the genes have the equal chance to survive and mating, the ratio of the gene pool should not change dramatically.

HELP ASAP!!!! All life on earth has descended from a common ancestor this theory was accepted when
kap26 [50]

Answer:

A. A majority of scientists agreed with it

Explanation:

The famous theory called the theory of common descent, states that all the living organisms of the earth have arisen from a common ancestor. This notion was first proposed by a French mathematician,Louis Maupertuis duirng 1740s who was of the view that all organisms had a single ancestor and evolutionary process with the passage of time resulted in the specie diversification.

After that, in 1790s another philosopher Immanuel Kant, suggested that all organisms seem to have a common ancestor. In the same period of 1790s, another scientist , Erasmus Darwin who was the grandfather of Charles Darwin also suggested that all the organisms might have a single ancestor who went through the process of evolution to bring all the majesty into life.

Charles Darwin was the first scientist who worked on this notion for alot of time and proposed the theory of common descent,in his book, On the Origin of Species.

After it, many scientists got agree with this theory such as,  Vernon Kellogg in 1907 and T. Ryan Gregory in 2008 and many others explain that no reliable observations exists which contradicts the theory of common descent.

Therefore, option A is the best option.

Hope it helps!

Arlecino [84]

Answer:

Fatty acid chains

Explanation:

A Triglyceride molecule is made up of 3 fatty acid chains and 1 glycerol molecule held together by ester bonds.

Digestion of lipids using lipases hydrolysed the ester bonds to release 1 molecule of glycerol and 3 molecules of fatty acid chains.
