Insect hormones and their receptors are a focus in pest control and research. Hence, Option B is correct.
Some of the insect hormones such as ecdysone (molting hormone), JH (juvenile hormone) and their analogs can be used for biological control of pests.
Option A: Hormone receptors are proteins that bind hormones and form hormone receptor complex to maintain cellular activities.
So Option A is incorrect.
Option B: Some of the peptide hormones used in pest control and research. So Option B is correct.
Option C: Peptide hormones interact with only cell surface whereas aminoacid derivatives and thyroid hormones directly interact with nucleus. so Option C is incorrect.
option D is incorrect.

The reason why the AIDs virus which contains RNA, to insert into the DNA of a host of T-cells after the AIDs virus enters the cell is because of receptor proteins located on the surface of the virus.
The organism that lacks the ability to maintain their own metabolic pathways and can only reproduce inside of a host cell are the viruses.

The protective covering of the brain
that provides passageways for cerebrospinal fluid (CSF) to drain into the
superior sagittal sinus is called the arachnoid mater.
To add, the arachnoid mater is the middle
of three layers that make up the meninges, or membranes, that surround the spinal
cord and brain.
Answer:
<h2>In all flies,on the same Locus, on chromosome 2 at the same place you find the gene for antenna length.</h2>
Explanation:
In all fruit flies ,on the same Locus, on chromosome 2 at the same place you find the gene for antenna length
All fruit flies contain same amount of gene and chromosomes, so the location of all gene in all fruit flies found at the same location.
A gene for antenna length in all fruit flies on chromosome 2 is present on same the location.
