Diversification Rates Increase With Population Size and Resource Concentration in an Unstructured Habitat
Answer:
The reactants and enzymes required for a particular biological process are concentrated in a particular organelle.
Slower
Explanation:
Enzymes are usually localized in organelles to make it easier for cellular processes to occur. Enzymes are NOT randomly distributed in the cell. Each organelle is capable of a specific function and uses specific enzymes to do these processes. Enzymes are very specific and only work for certain organelles, so they are appropriately distributed throughout cells to ensure biological processes can proceed appropriately. This is also why processes would run slower if they were just in the cytoplasm, because organelles have reactant-specific enzymes to do certain biological processes, which cannot be effectively done in the cytoplasm in the cell.
D. Artificial selection means that it doesn’t happen naturally, many dogs breeds exist because of artificial selection
Answer:
B) astrocytes
Explanation:
Cells other than neurons that play an important role in the normal functioning of nervous system are called Neuroglia or glial cells.
Satellite cells, astrocytes, schwann cells and oligodendrocytes are all examples of glial cells.
⇒Satellite cells provide protection and nutrition to cells in peripheral nervous system ( peripheral nerves and ganglia).
⇒<em><u>Astrocytes</u></em> play an important role in central nervous system (brain and spinal cord). They provide protection to neurons, scavenge ions, form the blood-brain barrier and also maintain extracellular environment suitable for neuronal functioning.
⇒Schwann cells are found in the peripheral nervous system and myelinate the axons of neurons.
⇒Oligodendrocytes are found in central nervous system and produce myelin sheath which myelinates (insulates) axons of neurons. Their function is similar to schwann cells but in the central nervous system.
From the above discussion it is clear that the answer is B) Astrocytes as these maintain a suitable chemical environment for the neurons.
