A model of pluripotent vs differentiated cellular gene expression is shown. Pluipotency is found in stem cells that have the ability to become multiple types of cells. Differentiation is the process where a cell becomes specialized and cannot return to its pluripotent state. What explanation best supports the model of pluripotency and differentiation shown above?A) Differentiated cells have different DNA sequences that pluripotent cells and can produce different protein products. EliminateB) Differentiated cells have fewer gene sequences that pluripotent cells and can only produce limited numbers of proteins. C) Pluripotent cells recruit molecules from nearby cells to increase gene expression while differentiated cells use only internal transcription factors. D) Differentiated cells and pluripotent cells have different types of activator or repressor proteins present that positively and negatively regulate gene expression in the cell.

Identify three of the seven common neurotransmitters and the functions of each. Then describe what each neurotransmitters controls or regulates in the body.

Answers

Answer:

One common neurotransmitter is dopamine. It is an excitatory neurotransmitter that is involved in movement, learning, attention, and emotion. GABA is another common neurotransmitter, and it is a major inhibitory neurotransmitter. It is involved in anxiety, arousal, and sleep. Glutamate is a major excitatory neurotransmitter, and it is involved in learning and memory.

Acetylcholine: Serves as a messenger between each motor neuron and skeletal muscles, which accounts for its role in helping to control skeletal muscles.

Serotonin: Affects sleep, hunger, mood, and arousal; connected to aggression and abnormal behavior

Norepinephrine: Helps control arousal and alertness; helps in regulating mood

Endorphins: Major excitatory neurotransmitter; linked to memory and learning processes; released in response to pain and intense exercise

Explanation:

:) have a good day

Answer:

Dopamine, Acetylcholine, Serotonin

When (Blank) travels through the space it is called radiation

Answers

heat waves or waves........

Final answer:

Radiation occurs when energy moves through space, such as heat or light from the sun. There are multiple types of radiation, but all involve energy travelling away from a source.

Explanation:

When energy travels through space, it is known as radiation. There are different types of radiation, but they all involve forms of energy moving through space. For instance, light and heat from the sun travel through the vacuum of space to reach the earth. This is an example of electromagnetic radiation. Other forms include alpha, beta, and gamma radiation. These all entail particles or waves moving away from a source and travelling through space.

Which explains how the moon causes low tides on the earth? A.
The moon exerts a gravitational pull on the earth. The pull stretches the earth's watery envelope and creates tidal bulges. Where the water bulges out is low tide.

B.
The moon's gravity pushes on the earth. The push indents the earth's watery envelope and creates tidal bulges. Where the water is pushed in is low tide.

C.
The moon exerts pull on the earth. The pull stretches the earth's watery envelope and creates tidal bulges. Where the water is thinnest is low tide.

D.
The moon's gravity pushes on the earth. The push indents the earth's watery envelope and creates tidal bulges. Where the water is pushed out is low tide.
