Answer:
B. neuroglia.
Explanation:
Neuroglia, also called glial cells are cells that support neurons structurally and functionally.
There exists two broad classes of cells in the nervous system which are:
- Neurons
- Glia
The neurons process information while the glia support the neuron mechanically and metabolically.
In general, there are three main types of cells that make up the nervous system including the above two.
Answer:
Mitochondria is known as the powerhouse of the cell as it provides energy to the cell for performing different functions.
If a toxin causes pore in the inner membrane of the mitochondria and increases the permeability of the mitochondrial membranes. The permeability of mitochondrial membranes leads to mitochondrial swelling and causes cell death through necrosis and apoptosis.
Answer:
The scientific claim that is most consistent with the findings in the question given is that: histone methylation opens up chromatin at gene R, so transcription factors can bind to DNA more easily.
Explanation:
The transcription of the R gene decreases when histone methyltransferase is inhibited, this proves that histone methylation increases the transcription of the R gene.
When the gene is in the condensed state, RNA polymerase can no longer gain access to the region so as to transcribe the R gene. Thus, in order for the gene to be transcribed, the gene has to be in the open (euchromatin) state.
Histone methylation makes the gene in the euchromatin state.
Therefore, the scientific claim that is most consistent with the findings in the question given is that: histone methylation opens up chromatin at gene R, so transcription factors can bind to DNA more easily.
