Answer:

Nucleus

Explanation:

In eukaryotic cells, the nucleus is a membrane-bound structure that contains the genetic material, which is expressed in response to cell stimuli (i.e., environmental stimuli). This genetic material consists of genes that are expressed in response to cell signaling events. For example, the transcription factors that are found in the cytoplasm are activated after receiving a signal from receptors localized in the cell membrane, when these membrane receptors bind to specific signaling molecules. Subsequently, these transcription factors are translocated into the nucleus to interact with DNA promoter regions in order to activate the expression (transcription) of target genes capable of responding to an environmental stimulus.

Which level of organization is characterized by a group of cells that work together to perform a common function
Whitepunk [10]

Hey there! :D

Organization in organisms is like this:

cells => tissues => organs => organ systems => organisms

Since we are talking about a group of cells, this would be a tissue. Don't let the word 'function' confuse you. Tissues do functions as well as an entire organ or organ system.

It is helpful to use the flow chart when asked questions like these, so make sure to memorize it! It will be helpful in any level of science.

I hope this helps!

The. of earth's rotation axis stays the same as it orbits the sun​
yuradex [85]

Answer:

The tilt of earth's rotation axis stays the same as it orbits the sun​.

Explanation:

The axis of the Earth is an imaginary line around which the Earth is known to orbit. The axis of the earth is known to tilt at an angle of 66 and a half degrees. The tilt of the axis of the Earth remains the same and it does nor change as the earth orbits around the sun. The orbiting of the Earth around its axis causes day and night to occur on the planet Earth. The rotation of the Earth around its axis is slowing with time.

If you lose a finger, the somatosensory cortex that received its input will begin to pick up signals from the neighboring finger
a_sh-v [17]

If you lose a finger, the somatosensory cortex that received its input will begin to pick up signals from the neighboring fingers. this best illustrates the concept of neuroplasticity. The neurons rewire themselves to participate in the functioning of other nearby brain regions. Another consequence of this in the experience of the presence of a phantom limb or finger. The brain activates that region to signal the muscles of the absent limb and confuses itself in the absence of any feedback from it.
