Scientists used gene therapy to restore the sight of the dogs who suffer from inherited blindness.
Inherited blindness is identified as retinitis pigmentosa. It is the <span>progressive loss of both the rods and the cones photoreceptors in the retina from the edge of the retina to the centre, leading to worsening tunnel vision caused by the loss of peripheral sight
</span>A human gene that enabled cells in the retina to become sensitive to light is added into the retina cells. The scientists then inject a chemical called "photoswitch" in the eye. It attaches itself to the <span>ion channel protein and enables the full conversion of light into an electrical signal relayed to the brain.</span>
Answer:
mineral resources like the Zinc, copper, gold and silver.
Explanation:
- The hydrothermal process usually includes the movement s of the subsurface hot waters and the upwelling of the magma from the earth mantel. This process leads to the formation of deposits such as those of the iron, zinc and gold and silver.
D) egg in Kayro syrup
Explanation:
An egg in Kayro syrup will experience plasmolysis. During the process of plasmolysis a body loses water to another one at a higher concentration. Fresh water organisms suffers plasmolysis because in salt water, the concentration of dissolved salt in the water is high and this makes the water hypertonic to their body.
- In a hypertonic solution, the egg will lose water and begins to shrink in the Kayro syrup.
- The Kayro syrup is hypertonic to the egg and by so doing, it will lose water to it.
