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.

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. All of these characteristics can aid investigators in establishing the existence of a crime and locating the offenders.

In the two-hybrid screening technique, what type of protein is separated into two different domains to determine if two other proteins attached to these domains will interact
Answer: Transcription factor
Explanation:
In the two-hybrid screening technique, the type of protein that is separated into two different domains to determine if two other proteins attached to these domains will interact is called the transcription factor.
Transcription factors are the proteins that helps in the conversion of DNA into RNA or their transcription. Transcription factors simply consist of a large number of proteins, that initiate are used in regulating gene transcription. It should be noted that a characteristics of the transcription factors is the possession of DNA-binding domains.

What is the purpose of having leak and gated channels for the neuron?
Answer:
Explanation:
The purpose of having leak and gated channels for the neuron is that the leak channels will allow the movement of sodium and potassium across the cell membrane downward from high concentration gradient to low concentration gradient. With the leakage of ions across the cell membrane, there is maintainence of a stable resting potential of cells.
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.
