it gets energy from the body fat cells
Answer:
B. some individuals are better adapted to exist in their enviornment than others are
Explanation:
The correct response is,
the sequences within the promoter region at -10 and -35 are the most important for recognition by the sigma subunit.
Promoter region is the DNA sequence located upstream of the corresponding gene. Promoters for genes are essential as RNA polymerase recognizes the promoter region and binds to it forming the holoenzyme complex which can inititate transcription of the gene located downstream.
Sigma factor is the transcription factor found in bacteria, RNA polymerase has a subunit for the sigma factor, this factor only can recognise the sequences in the promoter region and bind to it thus initiating transcription.
Promoters usually have 2 parts of conserved regions, -10 element and -35 elements. Both these regions have conserved sequences.
The sigma factor is capable of identifying these conserved sequences at these particular locations of the promoter and can bind to these sequences.
once the sigma factor binds to these regions, RNA polymerase too binds and forms a transcription initiation complex and then transcription of the downstream gene is initiated.
Therefore promoters need not have identical sequences for the sigma factor to bind, as long as the -10 and -35 regions have conserved sequences the sigma factor can bind and transcription initiation will be followed.
Answer:
A pedigree
Explanation:
A pedigree is the record of descent of an animal, showing it to be purebred. With a pedigree, a dog breeder would easily have proof of his purebred dogs' heritage.

Answer:
The old hyphae was left underground and a new mushroom will regrow from it.
Explanation:
Mushrooms is the fleshy part of a fungus that bears spores. Is found above the ground. It is comprised of parts such as the cap which is the top part.
Underneath the cap are the gills and the stalk or the stem is where the cap and gills are attached.
A part from the seen features, underneath the ground is where the hyphae which can give rise to another fruiting body or the mushroom.
