Answer:
HYDRA
Explanation:
The nerve cells are scattered in each layer of the body wall and these neurons send information from sensory organs. Based on the given choices above, the organism that has a nerve net that allows it to respond to a stimulus in a coordinated way is the HYDRA.
The structure of DNA is called a double helix because DNA is made up of two strands of nucleotides wound together in a spiral.
DNA has two strands that run opposite of each other and twist together much like a twisted ladder. Each backbone of the ladder is made up of alternating groups of sugar and phosphate groups.

Explanation:
Symbol Representation
I- laci mutant cannot bind to the operator
Is laci mutant always bind to the operator
OC Operator mutant that prevent repressors binding
F’ the wild type operator, O+, and laci gene on a plasmid
L lacZYA genes
I+ O+ L+ Inducible
I+ OC L+ Constitutive
I+ OC L+, F’ Constitutive
I- O+ L+, F’ Inducible
Is O+ L+ no transcription
Is O+ L+, F’ no transcription
Conventional genetic analyses of prions involving rrna sequences are impossible because Prions do not contain nucleic acids
The name "prions" refers to aberrant, pathogenic agents that are transmissible and capable of inducing improper folding of specific normal cellular proteins known as prion proteins, which are abundant in the brain.
Prions are virus-like creatures that contain a prion protein. These elongated fibrils (green) are thought to be protein aggregations from the infectious prion. Prions cause neurodegenerative brain illness by attacking nerve cells. Symptoms of "mad cow" include glassy eyes and uncontrollable bodily trembling.
Prion disorders develop when normal prion protein, which is found on the surface of many cells, becomes aberrant and clumps in the brain, causing harm to the brain.
