Answers
Answer:
Cytochrome C is a protein found in all species, and functions in energy metabolism. The more closely related two different species are,
C. the greater the number of differences there are in their amino acid sequences in cytochrome C.
Explanation:
Cytochrome c, unlike other cytochromes, is highly water-soluble. It is an essential component of the electron transport chain, where it transfers electrons between complex III and complex IV of the respiratory chain. It undergoes oxidation and reduction when its iron atom converts between the ferrous forms to the ferric forms, but it does not bind to oxygen.
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.
Answers
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.

What must be true of the concentration of potassium and sodium inside the neuron?
Answers
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.
