Answer:
Explanation:
Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.
Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.
Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.
Lysosomes
They store waste in the cell until it is ready to be disposed
Answer:
maintain homeostasis
Explanation:
Lizards are poikilothermic organisms, it means that their body temperature varies over the course of the day. There are poikilothermic organisms including lizards that bask in the sun during the morning and evening hours, and thus they can increase the body temperature
The gases present at the origin of the earth were believed to be nitrogen (N2), Carbon dioxide (CO2), water vapor (H20), and maybe some carbon monoxide (CO).
<h3>Origin of the earth</h3>
The earth is believed to have originated in what scientists have referred to as the big bang in which several gases were formed.
The gases present at the origin of the earth were believed to be nitrogen (N2), Carbon dioxide (CO2), water vapor (H20), and maybe some carbon monoxide (CO). The gases aggregated to form amino acids hence the origin of the initial life forms.
