Answer:
Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... During meiosis, a diploid parent cell, which has two copies of each chromosome, undergoes one round of DNA replication followed by two separate cycles of nuclear division to produce four haploid cells.
Answer:
D.) repressor DNA-binding site mutation
Explanation:
lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".
The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence.
This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.

<h3><u>Answer;</u></h3>
mechanoreception
In the context of sensation and perception, the detection of pressure by sensory receptors is called <u>mechanoreception</u>.
<h3><u>Explanation</u>;</h3>
- Mechanoreception involves detection and response towards certain kinds of stimuli such as touch, sound, and changes in pressure or posture.
- Mechanoreceptors are type of sensory receptors found on the skin and on other organs that detect sensations of touch. They are called mechanoreceptors because they are designed to detect mechanical sensations or differences in pressure.
