Efforts to restore wetlands and forests along the coast will most likely _______. a. benefit the economy by providing jobs b. improve wildlife populations c. reduce soil erosion and flooding in coastal areas d. all of the above

Answers

The right answer is D. all of the above.

The restoration and rehabilitation of wetlands are today major challenges to maintain a fabric of natural spaces with high heritage value. The ecological engineering that has developed over many years, inspired by methods of renaturation of coastal, alluvial, grassland and forest natural areas has specificities that it is necessary to share to allow access to the greatest number. This knowledge is built on the basis of feedback and scientific knowledge, which is itself constantly evolving. They constitute a base for conducting sustainable operations that are consistent with the maintenance of ecological trajectories as close as possible to the natural model in balance with human activities.

option d. all of the above

all the option have positive outcomes; benefit the economy by providing jobs, specifically it contributes welfare to the society. Improve wildlife populations, when you say improvement there is an additional change that makes something better or valuable. Reduce soil erosion and flooding in coastal areas; we cannot avoid it but we can prevent the destructive effect of this in our lives. Being prepared from those sudden change can restore wetlands and forests not just along the coast as well as to other areas.

Count the number of neutrons in Cesium-130/55 (Cs) A. 55 B. 75 C. 130 D. 185

Answers

The answer to the question is letter B which is 75. Cesium or also called as cesium is a chemical element with the symbol Cs. It is a silvery-gold element which is soft alkalai metal with melting point of 28.5 C.

the given element is

¹³⁰₅₅Cs

the superscript - 130 is the atomic mass / mass number

mass number is the sum of protons and neutrons

subscript - 55 is the atomic number

atomic number is the number of protons

therefore we can write the following equations

protons = 55

protons + neutrons = 130

so neutrons = 130 - protons

nuetrons = 130 - 55 = 75

number of neutrons = 75
