They produce many fish with food which is positive, but the negative impact they can have is when there are too many nutrients available phytoplankton can grow out of control, in which they will produce harmful algae blooms that are toxic and can harm sea life.
The options for this question are:
A. Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
B. All sensory cells and sensory neurons fire action potentials when they bind a signaling molecule.
C. Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
The best answer choices are:
A & C
Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
Explanation:
Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.
For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction. Sensory receptors located in the dermis or epidermises of the skin are called cutaneous receptors. These include nociceptors and thermoreceptors.

Asexual reproduction = Binary Fission = Mitosis
The cell at the end of asexual reproduction compare to the original cell: at the end is called daughter cell, at beginning is parent cell; both have same number of chromosomes (2n = diploid).
Answer:
As a result of the zebra mussels' huge appetite, populations of plankton in the Hudson River have fallen sharply. Microzooplankton, like the rotifer pictured below, have declined by 70%, while phytoplankton have decreased by 80%.
