art 1 Table 1 contains data from two bacterial growth curves. You will plot the data from each bacteria, using virtual graph paper. To do so, go to the following link: mvi- au. vlabs. ac. in/micro-biology-1/Bacterial_Growth _Curve/experiment. html A virtual graph sheet will come up on your screen. You will produce two graphs (one for each set of bacterial data) (5 marks for each graph). Graph each data point by placing your mouse at the point on the graph where the data point should go, and then click on the mouse button. Graph the rest of the data. Once you have finished the graph, take a screen shot of the graph and insert it into the powerpoint (one graph per slide). Follow the same step for the second graph. You need to label each graph as Graph One and Graph Two. Use the graphs to answer the following questions. Put your answers on additional slides of the powerpoint document. 1. label the growth phases of each graph (4 marks) Table 2. Bacterial growth data. Page 6 of 9 FOOD*2420 2. Which has the greater lag phase? Why? (2 marks) 3. Which bacteria has the greater death phase? Why? (2 marks) 4. Calculate the generation time for each bacteria. Be sure to show your work. (8 mark

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
