Petri (the person that invented the Petri dish) invented the transparent glass lidded dishes which were meant for keeping and growing bacteria and other stuff including fungi and mosses sterilized. It dated back to the late 1800s.
Dopamine is a chemical that serves as a neurotransmitter that governs the transmission of signal between the neurons (brain cells) through binding to the receptors. This is also referred to "reward hormone" because this is excreted during activities that causes too much excitement or satisfaction.
The severe reduction in this hormone is linked primarily to disease that results from the dissociation of the breakdown of this hormone. This causes muscular paralysis, tremor, slow movement. Further this causes difficulty in movement initiation. This disease described above is the Parkinson's Disease.

Answer:
- light positioning: c. Extrinsic muscles; d. Pupil
- sensory processing: a. Photoreceptors; b. Occipital cortex; e. Bipolar cells
Explanation:
Extrinsic (extraocular) muscles are muscles that modulate both eye movement and position, whereas intrinsic (intraocular) muscles are muscles that focus the eye and control how much light enters into the eye. The pupil is the black center of the eye within the iris through which light passes before being focused onto the retina. Photoreceptors are specialized neurons located in the retina that respond to light, converting it into electrical signals that can stimulate biological processes. Photoreceptors in the retina are divided into two categories 1-rods (responsible for vision at low light levels), and 2-cones (active at higher light). Bipolar cells are neurons that transmit signals from the photoreceptors to the ganglion cells, thereby processing light signals received from rods and cones. The occipital cortex is a brain region that represents the visual processing center and contains most of the anatomical region of the visual cortex.
<span>Question: </span>the amount of compostable waste that could be generated by one individual in a week would be closest to?
Given:
Average waste generated by an American per day = 2kg
Proportion of the waste that can be composted = 60%
Solution:
Let X = the amount of compostable waste generated by one individual in a week
X = X2kg*60%*7 days
X = 2(.6)(7)
X = 8.4 kg
