Which form of succession replaces
an
existing system after a calamity?
Answer:
Secondary succession
Explanation:
Ecological succession is the term used to describe any series of change in the composition of an ecosystem over a particular period of time. Ecological succession is made up of two types viz: primary succession and secondary succession.
Primary succession involves the formation of a brand new ecosystem by the colonization of a barren area of land e.g bare rock, where no life existed. Secondary succession, on the other hand, is the recolonization of an area by a new set of organisms because the previously existing organisms have been wiped out by certain disasters e.g fire outbreak, hurricanes etc. In secondary succession, there is soil, which makes it possible for new organisms to sprout quickly after the calamity.
Example of secondary succession is when a fire outbreak burns the organisms in a community, allowing the root of grasses to sprout after.

Which of the following best explains how a hurricane can increase an area’s susceptibility to future storms? a. Storm surges cause massive damage to buildings along coastlines. b. Hurricanes often flood coastal communities. c. Hurricane strength winds cause large amounts of property damage. d. Erosion caused by hurricanes can leave coasts more exposed to storms. Please select the best answer from the choices provided A B C D
Correct answer choice is:
d. Erosion caused by hurricanes can leave coasts more exposed to storms.
Explanation:
Important erosion, rapture, and removal of solids happen through storms. Beach erosion is a typical consequence of the high waves that transpire when hurricanes pass onto land. The decline of sand makes the beach to grow narrower and deeper in elevation. Storm loops take the sand offshore, keeping and depositing the sediment in great sandbars.

HELP Using your knowledge of nonrenewable energy sources, choose the answer that BEST describes the environmental impact (s) associated with these energy sources.
Non renewable energy sources such as coal, oil and natural gas contribute to air pollution and cost more money.
Non renewable energy sources do not really have any major impacts on the environment.
Solar energy is the best type of energy for the environment.
Non renewable resources such as coal, oil and natural gas contribute to air pollution, water pollution and global warming.
Answer:
Non renewable resources such as coal, oil and natural gas contribute to air pollution, water pollution and global warming.
Explanation:
Non-renewable energy sources are the energy sources that do not naturally replenish themselves. At some points in the nearest future, their sources would be become depleted.
Non-renewable energy sources such as coal, crude oil and natural gas contribute to the pollution of the environment in varying degrees. They require burning and this process leads to the release of gases such as carbon dioxide, carbon monoxide, oxides of sulfur and nitrogen,methane, water vapor, etc.
The released gases often posses different threats to organisms in the environment at certain level, constituting what is known as environmental pollution. Some of them dissolve in rain water to cause acid rain, some are directly poisonous when inhaled by living organisms, while a host of the pollutants absorb radiation from the sun and cause the warming of the planet, a phenomenon known as global warming.
Crude oil spillage or that of the any of its derivatives cause various environmental problems. They are poisonous to aquatic lives and render water useless for humans.

What is the definition of the length constant? What does the length constant tell you in terms of the electrical signal? Neurons are designed to maximize the length constant – why? What aspect of a neuron’s cable properties are manipulated to maximize the length constant? How are neurons modified (i.e. what is done to the structure of the neuron) to maximize the length constant?
Answer:
The overview of the given problem is outlined in the following section mostly on explanation.
Explanation:
The constant length seems to be a constant value which used to measure the distance between the grade electron density and the neurite through passive electron flow. The larger the quality of the distance constant, the faster the potential goes, throughout consideration of the electronic current.
The electronic replacement through one potential from neighboring areas including its cell will lead with the spatial description by a broad constant of length. This length decreases with either the size of that same neuron rising.The length constant, means of characterizing how much continuous current that flows extends until it bursts out from the axon, despite constants of limited period meaning leakier axons. The resistance of that same membranes should be just as efficient as possible as well as the tolerance of its axoplasm or extracellular media must be weak to enhance the efficient movement of current via an axon. Which of the following best describes a process that helps a cell maintain homeostasis without requiring energy to be used?
1. Channel proteins provide a passage for molecules to cross the membrane via facilitated diffusion.
2. Membrane carrier proteins help substances enter the cell against a concentration gradient.
3. Pieces of the cell membrane for vesicles circulate around extracellular materials during endocytosis.
4.Protons are pumped out of the cell to create a voltage across the cell membrane.
