<span>False. The plasma membrane is the outer layer of the membrane and its primary purpose is to protect the cell from its surroundings. It is selectively permeable to allow ions and other organic molecules to pass through and regulates which molecules are allowed in and out of the cell. It is a phospholipid bilayer that are placed back-to-back.</span>
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.
The answer is D I just took the test
Answer:
Option A, unique hair cells located anywhere along the basilar membrane
Explanation:
When ever a high frequency sound wave is perceived by the Organ of Corti, it magnifies. In the magnification process of Organ of Corti, basilar membrane and along with Organ of Corti moves up and down. On the top of Organ of Corti, the hair cells protrudes. With the movement of basilar and tectorial membranes up and down, the hair cells also move laterally.
Hence, option A is correct
A eukaryotic cell has a nucleus and a prokaryotic cell does not
