Answer:
Friction depends on the coefficient of friction which in turn depends upon the nature of the surface. Hence, this statement
is false.
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.

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.

living things are made up of cells and the product of cells. Explain what this means
Answer:
A living thing's first feature is that it is made up of cells. A cell is the basic structural unit of all organisms. It is the smallest organization structure in a living thing. They contain the organism's genetic information (DNA) and can replicate themselves in a process known as mitosis.

Explanation:
A botanist discovers a new species of plant in a tropical rainforest. Its characteristics include flagellated sperm, presence of xylem for conducting water, independent gametophyte and sporophyte stages, no seeds. This plant is most likely a
Answer:
Fern
Explanation:
The plant discovered by the botanist is most likely a fern.
Ferns are referred to as seedless vascular plants. They do not produce seeds and they possess vascular tissues in the names of xylem and phloem. The xylem conducts water/mineral salts from the roots to the body of the plant while the phloem distributes manufactured foods from their sources to other parts of the plant.
Ferns also have independent gametophyte and sporophyte stages. The sporophyte produces haploid spores through meiosis which then germinates to the gametophyte. The gametophyte produces male and female gametes - antheridium and archegonium. The antheridium is motile and swims to meet the immotile archegonium during fertilization to produce the zygote which then divides mitotically to give the sporophyte.
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.

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.
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:
Which of the following exceptions to the Fourth Amendment allow law enforcement officers to search email, telephone, medical, and financial records?
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.
