Answers

1. The correct answer is B. Conservation tillage practices help the soil erosion and also maintains soil nutrient levels.

Conservation tillage is termed as the tillage system which helps to conserve energy, soil, water through retention of crop residue and reduction of tillage intensity.

2. Correct answer is A. Aquifers 1 and 3 may result in a reduced river flow. Aquifer is termed as the underground layer of rock fractures, water-bearing permeable rock.

Hydrogeology is termed as study of water flow which is found in aquifers.

3. Correct answer is A. Recycling materials helps decrease the amount of new material which are taken from environment.

Most household can be recycled. Some other examples which are recycled include textiles, plastics, organics, and metals. Metals such as drinking bottles and food cans which are made from steel and aluminium can be recycled.

The ______ is the nerve tissue at the back of the eye, which receives the image that has been formed by the cornea, the pupil, and the crystalline lens.

Answers

The correct answer is that the retina is the nerve tissue at the back of the eye, which receives the image that has been formed by the cornea, the pupil, and the crystalline lens. The retina is a delicate tissue that it important to check on in the case of eye-strain, so that general eye health can be maintained.

Retina and crystalline lens

The lens concentrates on light through the transparent humor, a transparent gel-like material that permeates the back of the eye and controls the retina. The retina sustains the image that the cornea concentrates through the eye's inner lens and converts this image into electrical vibrations that are transported by the optic nerve to the brain.

The crystalline lens is the title given to the original lens that people are born with. Small muscles connected to the lens can make the lens to change its shape, which enables the eyes to concentrate on near or far objects.
