If the materials are sugars and gases, this process is diffusion. Water only moves through a cell membrane by osmosis.
I found the whole exercise with the options for it. Here are the options:
"A. mobility and protection of the DNA molecule during mitosis.
B. prevention of ligase enzyme action during replication.
C. Both answers regarding DNA mobility, protection and regulation in mitosis and transcription are correct.
D. regulation and protection of the DNA during transcription.
E. ensuring that sister chromatids will be attached prior to replication."
Correct answer: C.
Both A. and D. are correct reasons for what is the value in packaging DNA in tighter forms of chromatin. By having a more compact DNA it is easier to move it and protect each bit of it as it is being processed during mitosis, going from one side to the other, separating sister chromatids, etc. Also, by compacting and releasing DNA it is easier to regulate and protect DNA as it is being expressed - the parts that are being transcripted are not packed while those that are not being transcripted are packed.
<span>Recent studies strongly indicate a genetic link for schizophrenia. People with genes that don't support healthy brain synapses have shown a higher risk for becoming schizophrenic.</span>
Answer:
An experiment or trial that uses controls, usually separating the subjects into one or more control groups and experimental groups
Explanation:
The central nervous system (CNS) of the body, because the nucleus maintains and controls the functions of the cell, and the CNS does that for the body.
