A. Green

Explanation:

A green green house shade will be best to suit this purpose because green shades are best for nursery stock, pot plants, caladiums, lettuce and plants that require partial shade.

b) Blue

Explanation:

The color of light reflecting on plants tend to to affect photosynthesis (how the plants produce their food). Plants needs all visible colors of light except green. Plants react in different ways to different colours of light they are exposed to. The red light helps plants but only helps then to grow flowers, the yellow colour is not ideal because it will do little to protect from heat due to too much light. But the blue colour helps in good vegitative growth of the leaves and it also does a good job in absorbing heat.

Since the gardner wants to shade her plants with coloured transluscent plastic sheets, the ideal plastic sheet colour will be blue, because blue is a good absorber of heat and it also does tremendously well in the vegetation of plants.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
