Sunspots are storms on the Earth's surface.
WHAT ARE SUNSPOTS?Sunspots are darker and cooler areas on the surface of the sun in a region called the photosphere.
Sunspots form on the surface of the sun due to strong magnetic field coming up from the sun core.
Sunspots appear visibly as dark spots compared to their surroundings. Therefore, sunspots are storms on the Earth's surface.

I am doing the test as I answer this, these are some answers I checked.
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.

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.
UV light can be used to gather evidence of a crime because Ultraviolet light causes substances to fluoresce and give off visible light.
What is Ultraviolet Light?Ultraviolet light refers to one of the components of the electromagnetic spectrum between visible light and X-ray.
Visible light is the only electromagnetic wave that can be seen by humans, hence, UV radiation cannot be seen by humans but can be used to detect crimes.
Ultraviolet light causes substances to fluoresce and hence, give off visible light that can then be seen by humans.

First off, radioactive materials that may have been utilised to commit a crime are frequently found using ultraviolet light. For instance, radioactive materials may have been used in a bombing to cause the explosion.
What is the region for radioactive substances ?Even though they are invisible to the eye, these radioactive substances can be found using ultraviolet light. This can assist detectives in proving a crime was committed and locating the offenders. Second, you may use ultraviolet light to spot cool and warm spots at a crime scene.
Warm zones will show as red and cold areas as blue. This can help identify if a weapon was used or whether a fire was ignited. Additionally, it can It can also be employed to locate bodies or trace a bullet's course.
Finally, compounds that fluoresce and emit visible light when exposed to UV radiation can be found using this technology. This may be used to find biological evidence, including blood, semen, and other substances.
Additionally, it can be used to find chemical substances that might have been involved in criminal activity. Finally, ultraviolet light is a potent tool for obtaining criminal evidence. It can make things glow and emit visible light, reveal cold and warm zones, and detect radioactive materials.

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.
