Carbon is the main constituent of living organisms. Carbon atoms bond with other atoms to form chains such as proteins, fats and carbohydrates.
Answer:
<h2>Catabolite repression
</h2>
Explanation:
1. Catabolite repression: it is the positive control of the lac operon.
2. It results in an increase in the rate of transcription. Here, the CAP protein is activated by cAMP which then bind to the lac operon and facilitate the binding of RNA polymerase to the promoter to transcribe the genes for lactose utilization.
3. Role of glucose in catabolite repression is that It stimulates transcription from the lac operon, causing an increase in cAMP levels in the cell. Glucose decreases the levels of cAMP in the cell, result in repressing transcription from the lac operon.
1- bald eagle eats lizards
2- the tree is the Robin's home not sure what else it would be
3- maybe the Robin and the lizard compeat to not get eaten by the bald eagle
4- competition keeps everything in balance so one species or ecosystem doesn't take over
