The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.
<h3>What are homeotic genes?</h3>
- Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
- These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
- Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
- Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
- The loss of function of any of the gene changes the body pattern and affects the development.

Answer:
D. norepinephrine- botulism
Explanation:
Botulism does not effect the neurotransmitter 'norepinephrine'. Rather, botulism occurs due to toxic consequences on the neurotransmitter 'acetylcholine'. Acetylcholine is produced by the motor neurons so that the muscles can operate properly. Botulism blocks the discharge of this neurotransmitter, acetylcholine, not the neurotransmitter, 'norepinephrine'.
Botulism occurs due to the production of a very harmful neurotoxin, Botulinum, which is made by the bacteria. The inhibition of acetylcholine which occurs due to this harmful toxin causes paralysis.

Answer:
A stable condition
Explanation:
Dictionary Definition- a tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes
I don't know if they're supposed to be a list, but the interaction would be parasitic because the parasite feeds off the host and the host suffers.
