The right answers are B, C and D.
An enzyme is a protein with catalytic properties. Virtually all biomolecules capable of catalyzing chemical reactions in cells are enzymes; some catalytic biomolecules, however, consist of RNA and are therefore distinct enzymes: they are ribozymes.
An enzyme acts by lowering the activation energy of a chemical reaction, which increases the rate of reaction.

<u>-The Retina</u>
<u></u>
The retina is a thin, transparent layer at the periphery of the eye's interior. Light enters the eye and is detected by specialized neural cells. The light is converted into an electrical impulse, by photosensitive rods and cones. This impulse is transmitted and interpreted by the central nervous system or CNS.
Further Explanation:
The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.
The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system;

Answer: The statement is TRUE.
Explanation:
Gram negative bacteria is a type of bacteria that possesses, from the interior to the exterior, a cytoplasmic membrane, a thin peptidoglycan layer, and an outer membrane containing lipopolysaccharide. The lipid portion of the lipopolysaccharide complex of the outer layer acts as an ENDOTOXIN.
The endotoxin of the gram negative bacteria can be detected in research or biomedical laboratories through a technique called LIMULUS AMEBOCYTE LYSATE test.
The test procedure follows a principle that the endotoxin of these gram negative bacteria are capable of forming gel clots (coagulation) of blood cell (amoebocytes) lysates of the Limulus polyphemus crab.
Therefore, If LAL (limulus amebocyte lysate) turns into a gel when exposed to a sample, it
means the sample is contaminated with endotoxins of gram-negative bacteria.
They have little things at the ends that are almost like sensors that detect and analyze what you're supposed to feel and they send a signal to you brain to tell you how to react.
