Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
Answer:
They digest without the use of teeth.
Explanation:
The food trickles from the crop into the bird's stomach (proventriculus or gizzard) where digestive enzymes are added to the mix and physical grinding of the food occurs. The gizzard is why chickens do not need teeth.
This is on account of every chromosome just has up to 50 units so when it surpassed this number it's on an alternate chromosome, along these lines it can't be connected.
One can decide whether qualities are connected or not by taking a gander at the posterity and deciding the recombination recurrence you can do this by taking the aggregate number of posterity that were recombined and partitioning it by the aggregate
Correct answer: Glycogen
Glycogen is a form of polysaccharide of glucose molecule which serve as energy storage unit in the humans. The excess glucose in the body is stored in the form of glycogen in the muscles and the liver.
The muscles can store upto 500 gram of glycogen and liver can store 100 gram of glucose. Therefore, any carbohydrate which is consumed beyond this limit are converted to and stored as fat.
Glycogen that are stored in muscle are broken down into glucose while the liver cell glycogen are broken down into glucose as a circulating energy source to be used by the body.
Answer: C. The mutation resulted in a beneficial trait that enhanced survival.
Explanation:
The bacteria was able to "evolve" and adapt to the Nylon being in its environment.
