Images are focused by the lens onto the retina which is a face at the back of the eye upon which light sensitive cells (rods and cones) convert the incident light into electrical signals that are transmitted to the brain.
The fovea is a pit directly behind the lens on the retina that contains a concentration of light sensitive, closely packed cones (colour sensitive cells) and is responsible for sharp central vision.

b and e kills organisms, so it doesn't evolve the diseases. genetic modification causes the plants to be resistant, and doesnt target diseases, so the disease isnt evolved. only antibiotics make diseases evolve, overuse of it causes the disease to develop resistance if it isnt completely killed off.

Answer:
D) High-technology recycling provides many more jobs than low-technology recycling
Explanation:
High technology means that less labor is required for manual tasks. All manual tasks would be catered through technology which means that a lower number of labor would be required.
Therefore the statement that high-technology recycling provides many more jobs than low-technology recycling is false because it actually takes away jobs rather than providing jobs.
I hope the answer is helpful.
Thanks for asking.
Answer:
James Carter enacted strict laws that limited the exploitation of natural resources, limited the use of non-renewable energies and increased the size of environmental reserves.
Explanation:
In the early 1980s James Carter turned his administration over to a policy with a strong environmental bias. He started by hiring influential environmentalists to hold some government positions, in addition to asking them for constant advice on nature, its exploitation and the degradation that could occur.
As a result, he enacted numerous laws that exercised serious environmental protection regulations, limiting their exploitation, the use of non-renewable energy, the burning of fossil fuels, in addition to doubling the areas of environmental reserves and areas of environmental protection. This had a bad effect on businessmen, who claimed that these regulations reduced the factors of production necessary for the manufacture of goods and services and, therefore, hurt the economy.
