Answer: 25% of the children will have both anirida and migraine headache
Explanation: The man has a dominant gene for anirida and normal headache with a mom with no blindness. Therefore, the man gene is (Nn) for heterozygous anirida and (mm) for normal headaches and his wife has heterozygous gene for migraine (Mm) 'cause her dad has normal headache and homozygous gene for normal vision(nn) .
Therefore
Nnmm × Mmnn= NnMm Nnmm Nnmm nnmm.
The crossing would give birth to Offspring with nirida and migraine (NnMm) =1/4 ×100= 25%
Answer:
lateral inhibition in the retina
Explanation:
Horizontal cells are in contact with photoreceptor cells through the synapse. One photoreceptor forms an excitatory synapse with horizontal cell in the adjacent regions of the retina while the horizontal cell forms an inhibitory synapse with another photoreceptor.
Hence, as one photoreceptor activates the horizontal cell, the horizontal cell, in turn, inhibits the other photoreceptor cell and thereby reduces the quantity of neurotransmitter released at the bipolar cell. In this way, horizontal cells transmit lateral inhibitory stimulus to the photoreceptor which in turn improves the contrast at the edges of the object.
organisms descended from more than one ancestor since algae has association with multiple other organism.
Explanation:
<span>Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation.</span>
A virus is basically a shell of DNA. It floats around until it finds a cell to latch onto. It then tricks the cell into absorbing the virus and the virus unleashes the DNA its carrying telling the cell to quit doing its job, and make more of the virus. <span />
