One activity would be logging of trees, which could be selective or clear cut. It is done to provide wood for building houses and for pulp for paper primarily. A short term effect would be loss of habitat for forest wildlife and removal of vegetation and it could result in increased erosion if in a mountainous area. Loss of old growth forest possible too. Long term effect if re-forested could be partial restoration of habitat. Another activity is open pit mining whereby the land where the orebody is is cleared and mining creates sometimes large holes in the ground and removes old lake habitats for migratory birds and fish in the short term.The purpose of the mining is partly to provide metals to society. The long term, if adequate reclamation of waste dumps is undertaken, can lead to extensive new grasslands on the dumps and forage for deer and moose and sometimes cattle. Oil production and transport on oceans can lead to oil spills such as occurred off Valdez in the 1980's or in the Gulf of Mexico recently and the short term is soaking marine animals with oil and killing many of them and contaminating beaches and shorelines. Some clean-up can be done but the long term effects of this activity may still be unknown. The oil is for fossil fuel for internal combustion engines but it will need to be replaced by say, electric cars for the future ie to clean energy. Another general effect of this time, the use of fossil fuels is from global warming is creating more and more intense hurricanes such as occurred in the Caribbean this fall in Cuba, Florida, Dominca and Puerto Rico in particular with the result of widespread damage or destruction of people's houses, flooding, loss of power and costly repairs and loss of life. Only by limiting the production of greehouse gases by mankind will there be a chance to reduce the incidence and intensity of such events.
The given question is incomplete. The complete question is:
Which statements describe transform boundaries? Select two options.
Rift valleys are formed.
Mountains are created.
Faults form in the lithosphere.
Plates move toward each other.
Plates slide in opposite directlồns.
Answer:
The correct options are that formation of faults takes place in the lithosphere and the sliding of the plates takes place in the opposite direction.
Explanation:
The transform boundaries signify towards the site where sliding of the plates takes place past each other, it is also called transform plate boundaries. In the process of the formation of the transform boundaries, neither the formation nor the destruction of the lithosphere takes place, however, in the process formation of thin rift valleys occurs.
The majority of the formation of the transform boundaries are witnessed on the floor of the sea. These boundaries possess the tendency of giving rise to earthquakes of high intensity that imparts a deleterious influence on the ecosystem. California's San Andrea is an illustration of transform boundaries.
Mitochondria are the powerhouse of the cell, they convert sugars into energy.
Answer:
A and C would result into flowering.
Explanation:
A short day plant is a plant that requires longer period of darkness (longer nights). According to the fundamental concept, these plants produce flowers when the length of darkness is equal or higher than the critical night length. In the given statement, the critical night length is 15 hours, therefore, the flowering will happen only in the A and C option whereas flowering will not take place for B.
Decomposes are biotic (non living) and the also decompose and do not eat
