The majority of water molecules moving across plasma membranes by osmosis do so via a process that is most similar to simple diffusion. The process of osmosis involves the moment of water molecules across a semipermeable membrane like the cell membrane from a region of high water concentration to a region of low water concentration. This process is similar to the process of simple diffusion where the solute particles move across in a similar fashion.
Parallel circuits are circuits when placed in a parallel
position. Meaning that for each device, they have their own branch. The voltage
that is received in the circuit is equal to the individual devices. The total
current is equal to the current of each device. The resistance is the reciprocal
of the resistances of each device combined.
Given:
Device 1 = 12 ohms
Device 2 = 4 ohms
Voltage total = 40V
Required:
Current at 12 ohms
Solution:
40V = V1 =V2
Since V =IR
I1 = V1/R1
I1 = (40V)/(12 ohms)

Answer:
True
Explanation:
Oogenesis includes the formation of one egg cell from a single oocyte or egg mother cell. The diploid primary oocytes in the ovaries enter into the first meiotic division and form a haploid secondary oocyte and a haploid first polar body. After fertilization, the secondary oocytes complete the meiosis-II and forms one large ovum and a second polar body. The ovum formed by meiosis-II is much larger than the second polar body due to the unequal distribution of cytoplasm during meiosis-II. This imparts enough amount of cytoplasm in the zygote to support the mitosis without any cell growth.
This is because if the two metabolic processes were to be active at at the same time;
Two molecules of<u> ATPs</u> and <u>Guanosine triphophate </u>(sometimes used for energy transport) <u>will be expended per each cycle, with no compensatory rate of replacements present at the moment in the cell,this affects cell metabolism for energy availability</u>
<u>2</u> Both<u> Glycolysis and Gluconeogensis </u>are both<u> exergonic processes in cells. </u> The heat energy liberated from these Calorinogenic effects will be higher than what the natural thermodynamic barrier of cells can withstand. Consequently; the heat will raise temperature of the cells affecting metabolic activities of hormones and enzymes which are (proteins) ,and easily denature by high temperatures.
However, in muscles cells,gluconeogeneis is a compensasory process of Glycolysis. This because during active exercise with high metabolic demand in muscles cells, glucose is rapidly metabolise to to pyruvate,(but not at the rate that the Citric acid cycle can metabolise) for Lactic acid production by muscles cells for energy production. Pyruvate must be broken down rapidly so that NAD+ will be available for Glycolysis to continue. Therefore to sustain Glycolysis at this rate continuous supply of glucose is supplied from Gluconeogenesis.
Lost phosphorus is actually recycled through the processes of mineralization, reabsorption, dissolving, and precipitation.
