Answer:
The cells of the visual cortex are neurons in the brain's visual system that respond to particular features of a stimulus.
Explanation:
These neurons respond to stimuli presented to both eyes. Simple cells receive innervation directly from thalamic cells and respond to light stimuli with defined orientation and with specific configuration and location in the visual field. Complex cells also respond to the orientation parameter.
These cells trigger action potentials when the visual stimulus appears within their receptive field.
<span>4 molecules of oxygen. Haemoglobin is a protein found in the red blood cells, which carries oxygen to the cells to perform cellular respiration. Each red blood cell carries around 250 million haemoglobin. So the entire capacity of an RBC is around 1 billion oxygen molecules.</span>
The tissues found within the vein if I must say are xylem and phloem. Glad I can help.
Answer:
a biological community of interacting organisms and their physical environment.
Explanation:
Mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides. All cells possess DNA-repair enzymes that attempt to minimize the number of mutations that occur
