What must be true of the concentration of potassium and sodium inside the neuron?
Answer: The sodium/potassium (Na+/K+) pump introduces two potassium ions that were outside and expels three sodium ions that were inside the neuron. After that, the sodium ions cannot re-enter the neuron, because the membrane is not permeable to it. This means 3 positive charges are lost every time the pump works and this makes that in the outside there are more positive loads that in the interior, creating a difference of potential. When the nervous impulse reaches a neuron in a state of rest, the membrane is depolarized, and this opens the channels for sodium, thereby the polarity is inverted. At the end, the neuron must return to the initial rest potential and the membrane is repolarized, closing the channels for sodium.
Explanation:
A neuron is a type of cell found in the central nervous system that is able to receive, process, decode and send information in the form of electrical or chemical signals through the process of synapses. This allows the transmition of information to other cells in the form of nerve impulses, which translates into "instructions" for the rest of the organism. So during the synapse, this process can be of two types:
Chemical synapse: neurons release and receive neurotransmitters, which are small molecules that carry information.Electrical synapse: it is faster and bidirectional, characterized by the transmission of ions between neurons through protein connections, called gap joints or cleft joints, without the intervention of a neurotransmitter.The information between neurons is transmitted by changes in the polarity of the cell membranes, due to the presence of neurotransmitters that alter this ionic concentration inside the cell. So they are responsible for depolarizing the membrane of the neuron that receives the nerve impulse, opening the channels for sodium that remained closed before. The difference in ion concentration produces a difference in the potential between the exterior of the membrane and the interior of the cell, and it is achieved by the action of the sodium/potassium (Na+/K+) pump which introduces two potassium ions that were outside and expels three sodium ions that were inside the neuron. After that, the sodium ions cannot re-enter the neuron, because the membrane is not permeable to it. This means 3 positive charges are lost every time the pump works and this makes that in the outside there are more positive loads that in the interior, creating a difference of potential. It is said that the neuron is in rest potential, ready to receive a nervous impulse.
When the nervous impulse reaches a neuron which is in a state of rest, its membrane is depolarized, and this opens the channels for sodium, thereby the polarity is inverted. After this, the interior of the neuron reaches an electropositive value, with respect to the exterior. Initally, the value is about -70 millivolts (negative the interior with respect to the outside). When there is a change of potential of 120 millivolts more than the interior, the action potential has been reached and there is a transmission of the nervous impulse to the next neuron.
At the end, the neuron must return to the initial rest potential and the membrane is repolarized, closing the channels for sodium. Enzymes destroy neurotransmitters and the rest potential is reached when the sodium is expelled by the Na+/K+ pump.

Trieste was the name given to a Bathyscaphe which was designed by the Swiss and built by the Italians. A Bathyscaphe is a deep-sea vehicle or submersible that is able to propel its self and will require the presence of a crew cabin. Jacques Piccard and Don Walsh jointly achieved the goals of Project Nekton one of which was to get to the bottom of the challenger deep. The challenger deep is the deepest point in the earth's sea bed. Auguste Piccard is an Italian and the son of the man who designed the boat: August Piccard whilst Don Walsh is a US Navy Lieutenant.Edward Forbes is considered the pioneer of oceanography and his area of specialty was the biological components of the ocean. Matthew Maury, on the other hand, is considered the father of oceanography because he focused on the physical components of the ocean such as currents, waves and temperature fluctuations.Echo sounding is a special sonar that is used to calculate the exact depth of water. The device does this by transmitting sound waves into water the speed is calculated. Sofar station was finished on the 4th of July, 1946. The full meaning of SOFAR is Sound Fixing And Ranging. It was designed or built to be able to locate stranded paramilitary such as Navy and Airforce survivors at sea.The continental shelf is estimated by some to be approximately 30 miles wide. The continental shelf is a space beneath the ocean that speads out like a plateau and which holds a lot of biotic elements.Waves are generated when wind flows over a water body in one direction for a protracted period. The Fetch is the oceanographic term for that area in the ocean where this phenomenon is prevalent.Alvin is another name for DSV-2 - a deep ocean submersible owned by the United States which has made a deep dive at least 5000.Cheers

are human nails exoskeleton
Answer:
no, the nails are not an exoskeleton
Explanation:
Humans don't have an exoskeleton. Invertebrates have an exoskeleton and vertebrates have an endoskeleton.
Hence, the nails are not exoskeleton, the nails are derivates of the skin. We don't need our nails to survive, but they do support the tips of our fingers and toes, protect them from injury, and help us pick up small objects

Between 1955 and 1977, groundwater was used to irrigate crops in the San Joaquin Valley. Which of these was a consequence? A. An increase in ground altitude B. Wetland sprawl C. A decrease in soil salinity D. Groundwater depletion
Answer:
D. Groundwater depletion
Explanation:
Groundwater is the water that is found just under the surface of the earth.
The effect of using groundwater to irrigate crops between 1955 and 1977 in the San Joaquin Valley was that there was groundwater depletion as there was scarcity of groundwater, even as the irrigation brought increase in yield.
If humans cannot see ultraviolet waves, how can ultraviolet light be used to gather evidence of a crime? Ultraviolet light detects the presence of radioactive substances. Ultraviolet light shows cold areas as blue and warm areas as red. Ultraviolet light causes substances to fluoresce and give off visible light. Ultraviolet light transmits information to AM and FM radio receivers.

The illustration shows one of the ways resources are removed from the deep sea. Describe what type of resources these are, including if they are renewable or non-renewable. Predict two consequences to the seafloor life if this process is not regulated.
Answer:
Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.
Explanation:
The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.
The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.
Two possible consequences of not regulating marine mining are:
Destruction of the habitat of life forms present on the sea floor, which endangers many species and even forces migration to more stable areas, with consequences on the food chains. Extinction of marine species that inhabit the seabed. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.

Correct answers are:
a - 1.
b - 2.
c - 4.

Answer:
a is 1, b is 2, c is 4, and d is 3.
Explanation:
organisms passing on genes to their offspring (the next generation) is what we call hereditory genes.
giraffe offsprings having different spots than their parents is variation. each giraffe has a variety of different spots.
fish having more offspring and having limited resources means competition for the limited resources.
lastly, individuals who are stronger/faster strive to survive so the can reproduce.
