The correct answer is a.
Even-aged practices remove larger groups of trees than uneven-aged management practices. Uneven-aged management is termed as the forest management whereby trees of different species are maintained for many sizes and ages to allow continuation of natural regeneration.
If the inducer [allolactose] is present in the negative control then it will bind to the repressor decreasing its ability to bind to the operator due to which the transcription begins again and the operon is turned on.
Lac Operon is a set of three genes z, y & a which are regulated under the same promoter which regulates the amount of lactose production in the cell.
An inducer is a molecule that has the ability to induce or activate the operon. ex- in the case of the lac operon, allolactose acts as an inducer.
A repressor is a molecule that will repress or restricts the transcription of the genes of the operon, as a result, the operon will be switched off.
When the lac operon is under negative control, with no CAP [catabolite repressor protein] binding activity, the repressor remains active and thus binds to the operator region of the operon, as a result, no transcription takes place and the operon will be switched off.
But if the inducer will be present even in the negative control then the transcription takes place and the operon will be on.

Answer:
It is consider less sequentisl because
- It is accidental death of cells whereas Apoptosis is a programmed death.
- It is caused due to injuries or damage but Apoptisis is caused due to the breakdown of cytoskeleton by enzymes.
- It damages other cells when died due to harmful chemicals whereas when cell dies by Apoptosis the other cells it it up..
Answer:
Here's an example
Explanation:
Imprinting allows baby birds to understand appropriate behaviors and vocalizations for their species, and also helps birds to visually identify with other members of their species so they may choose appropriate mates later in life.
