What are barrier islands? What protects the barrier islands?
Answer:
Barrier islands form in three ways. They can form from spits, from drowned dune ridges or from sand bars. Longshore drift is the movement of sand parallel to the shore caused by the angle of the waves breaking on the beach. When a storm such as a hurricane digs an inlet through the spit a barrier island is formed. Barrier islands are a specific type of island that lie parallel to the coastline of a larger mainland. They are separated from shore by a bay, lagoon or sound and because of where they are situated, they protect the coast from being directly impacted by storm waves or winds.
Explanation:
1.what did magnesium and oxygen atoms had to do to bond ?
2. why did the oxygen atom needed two sodium atoms to bond ?
3. why did the magnesium atom needed two fluorine atoms to bond ?
please put the numbers in order so i know which answer is for the questions thanks <3
Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

Main idea or the topic of finding the epicenter of an earthquake.
Answer:
Main Concept Seismology is the study of earthquakes, their effects, and seismic waves.
Explanation:
The earthquake epicenter is a point on the Earth's surface directly above an earthquake. Scientists determine the epicenter by studying the P waves and S waves produced by all earthquakes. P waves are compression waves and travel faster through the Earth than S waves.
i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answer:
1.0 mol per dm^3 sodium chloride solution
Explanation:
The idea behind this question is that the water inside the potato stick would move into the surrounding liquid naturally if the density outside the stick is greater than it is inside. Therefore, the liquid that would most encourage the flow of water from the potato stick would be the moet dense liquid- which in this case, is 1.0 mol per dm^3 sodium chloride solution.

Does the fossil of Archaeopteryx support Darwin's idea? Explain your answer.
(look at picture and read)
Answer:
yes
Explanation:
An analysis of fossil traits indicates that Archaeopteryx is not a bird at all. ... Archaeopteryx seemed to confirm Darwin's theories and has since become a key piece of evidence for the origin of birds, the transitional fossils debate, and confirmation of evolution.
The key aspect of receptor-gating in the associative induction of hippocampal LTP is that Group of answer choices the NMDA receptor acts as a molecular coincidence detector. both the NMDA and AMPA channels must be open in order for the cell to depolarize. The NMDA receptor allows the flow of magnesium into the cell. all glutamate receptors open automatically whenever glutamate is in the synaptic cleft. the AMPA receptor allows calcium into the cell only after the NMDA receptor is activated.
Answer:
The correct answer is NMDA receptor acts as a molecular coincidence detector.
Explanation:
The hippocampus works entirely for memory processes (especially new learning). Lasting depression (LTD) is also considered as another form of expression of synaptic plasticity. Long-term potential occurs when pyramidal neurons are depolarized and stimulated by excitatory input. The neurophysiological basis for LTP is certainly related to a subtype of NMDA of the glutamate receptor. This receptor behaves as a coincidence detector between pre- and post-synaptic activity, with an increase in glutamate release at the presynaptic level coinciding with a Postsynaptic depolarization that allows the entry of ca2 +. The NMDA receptor has been proposed as the basic mechanism of learning, because it has the ability to associate different signals, for all this it is necessary to know what neurotransmitters are, their function and what is the role of the receivers in them.

A.
voluntary consent
B.
hot pursuit
C.
the USA PATRIOT Act
D.
exigent circumstances
E.
Miranda exclusion
Answer:
C. USA PATRIOT Act.
Explanation:
The USA PATRIOT Act of 2001 enables law enforcement officers to search emails, telephonic conversations, medical, library and financial records. The USA PATRIOT Act stands for Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act. This act was enforced into the law after the terrorist attack on the World Trade Center and the Pentagon on September 11, 2001.
The Fourth Amendment of the Constitution protects the rights to privacy of it's citizen but with exceptions. The USA PATRIOT Act is one of those exceptions. Under this exception the police officers have permission to search email, telephonic conversations, medical, library and financial records without warrant, if there's any hint of possible threat.
Therefore, option C is correct.

In 3–5 sentences, describe how carbon dioxide levels can be reduced in the atmosphere.
Answer:
Walk to places as much as possible to reduce co2 emissions from cars.
Explanation:
The levels of carbon dioxide is higher in the atmosphere than it was before because of the human activities, which is eventually leading to global warming. Carbon dioxide being one of the most important greenhouse gases is present in abundant concentrations in the atmosphere and there is a need to reduce the levels to have some relief from global warming.
Some of the ways of reducing the levels of carbon dioxide in the atmosphere are:
• Planting more trees as trees are mainly good at storing carbon by the process of photosynthesis.
• Another way to use photosynthesis to fight against climate change is the use of bio-energy with carbon capture and storage technique. It is the process of utilizing biomass as the source of energy in the power sector.
• Another way to capture carbon dioxide directly from the air is by chemically scrubbing carbon dioxide directly from the ambient air, and then storing it either in the long-lived products or underground.
Thus, there are some techniques, which can be implemented to reduce the concentration of carbon dioxide from the atmosphere.
