Mike always has to adjust the blinds in his office because of the sunlight. what could be a solution to develop a better set of window blinds? a) install a timing mechanism and set it to open or close at a specific time b) install a sensor that monitors the amount of sunlight c) buy better window blinds d) buy darker window blinds

B

Explanation:

A sensor, usually photoelectric, that monitors the intensity of sunlight is better because, in case of high intensity, the blinds are automatically closed or almost closed allowing little sunlight to enter through and light up the office. In case of low-intensity sunlight, the blinds automatically open or are more open allowing much of the sunlight from outside. This way Mike does have to keep adjusting his blinds.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
