They are predators, they can climb up and down very sleep slopes
Answer:
In human vision, the cone visual opsins are grouped into four photoreceptor protein families LWS, SWS1, SWS2, RH2
.
- SWS1: produce pigments sensitive to very short wavelengths, UV-violet, 360-450 nm.
- SWS2: produce pigments sensitive to short wavelengths, blue, 450-495 nm
- RH2: produce pigments sensitive to medium wavelengths, green, 495-560 nm
- LWS: produce pigments sensitive to long wavelengths, yellow-red, 560-770nm.
Explanation:
Photoreceptor proteins are light-sensitive proteins that mediate light-induced signal transduction, thus they are involved in the sensing and response to light in a variety of organisms.
The photoreceptor proteins are classified based on the chemical structure of the chromophores involved, the light absorption and on the protein sequence.
This photoreceptor proteins are located at the cone photoreceptor cells and are responsible of photopic vision.
For scotopic vision, rhodopsin is responsible. Rhodopsins are the visual pigments (visual purple) of the rod photoreceptor cell in the retina. They are responsible of human vision in dim light, as it contains a sensory protein that converts light into an electric signal.
Answer:
a) another living cell
Explanation:
"All living cells arise from pre-existing cells by division."
Answer:
The correct answer is - The cranial nerves and the spinal nerves.
Explanation:
The central nervous system or CNS includes the brain and the spinal cord of the nervous system where it takes sensory information, integrates, and responds accordingly. The spinal cord acts as a conduit for signals between the brain and the rest of the body.
Spinal nerves and crania; both play an essential role in taking sensory information and respond accordingly. Spinal nerves are nerves that help in sending motor, sensory, and autonomic signals between the CNS and the body. The cranial nerves supply information to the CNS and then from the CNS to the body.
Thus, the correct answer is - The cranial nerves and the spinal nerves.
