The barnacles are only able to attach them selfs to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
Enzymes are not used in the reaction so usually the enzyme will sort of reset and be ready to use in another reaction . this is because enzymes are proteins and their shape is what they use in a chemical reaction so when the reaction is done the product is released (the reaction) and the enzyme can relax and go back to its normal shape
prophase
Further genetic variation comes from crossing over, which may occur during prophase I of meiosis. In prophase I of meiosis, the replicated homologous pair of chromosomes comes together in the process called synapsis, and sections of the chromosomes are exchanged.
Hope it helps!
They are accepted as true until they are proven false. Once a theory has been tested and it is wrong, then it is no longer true.
The central nervous system is made up of mainly the brain and the spinal cord while the peripheral nervous system is divided into two types which are sensory and motor neurons. The somatic nervous system is associated with voluntary nerves while the autonomic nervous system is also known as involuntary nervous system. The sympathetic nervous system increases or speeds up a process while the parasympathetic nervous system decreases or slows down a process.
