Answers
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.

Diatoms are white, porous and soft I'm nature. When it's die, it's leave it's shells which is made of silica glass.
The silica glass is some how abrasive which is why it is use as toothpowder.
Diatoms are microscopic bit of silica glass which are use as fine abrasive in toothpaste to clean teeth.
The cell wall of a plant-like protists called diatoms helps in cleaning our teeth.
What are diatoms?Diatoms are small protists which when dead, they are incorporated into glass particles.
Toothpaste have fluoride as it's main component.
Fluoride is obtained from fluorspar.
There, the cell wall particles of the diatoms which are plant like are incorporated into toothpastes.

Which form of succession replaces
an
existing system after a calamity?
Answers
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.

Why is there a border between light and dark on the moon
Answers
Answer:
As the Moon orbits around the Earth, we are able to see more or less of the half that is illuminated. ... There is a border between light and dark on the moon because the sun illuminates the half of the moon that is facing it. Leaving the other half dark.
Explanation:
Hope this helps!
The moon is the earth's only natural satellite and it gets its light from the sun. The moon changes its phases from a new moon to a full moon.
The terminator is the dividing line that is found between the moon's lighter and darker sides. It is sometimes known as the twilight zone. It can be seen during the rising and setting of the sun. The line is there so as to indicate the difference between night and day. The sun can illuminate only that part that is facing it. As the moon also rotates around the earth only that side is visible.Hence the sunlight travels in a straight path and can't reach the other side.

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
Answers
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.

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?
Answers
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.What is the purpose of a pedigree ?

a) The intracellular domain has phosphatase domains.
b) Some RTKs are dimeric in the presence of a ligand.
c) Ligand binding is required for autophosphorylation (cross‑phosphorylation).
d) The structure includes a transmembrane helix.
e) The α subunit contains seven α helices that span the membrane.
f) A ligand binds to the extracellular domain.
Answers
Answer: B,C,D,F
Explanation:
Of the given propositions it is correct that:
B. RTKs are generally (but not always) monomeric in the absence of ligand.
The observed structure of most RTKs are monomeric, thus their structure will adapt to the needs of the organism
C. A ligand binds to the extracellular domain.
When the cell can express extracellular domains, many of the ligands that circulate through the medium will be able to find their targets and trigger reactions.
D. Ligand binding is required for autophosphorylation (cross phosphorylation).
After the ligand finds its domain, the union will generate conformational changes, including autophosphorylation. which will produce chain reaction
F. The structure includes a transmembrane helix.
it is true that the membrane has a propeller that allows its conformation
