Diabetes is caused bymultifactorial disordersdestruction of erythrocytemonogenic disordersabsence of melaninmonogenic disorderRequired |
|
Answer» Answer: Monogenic diabetes is caused by mutations, or changes, in a single gene. These changes are usually passed through families, but sometimes the gene mutation happens on its own. Most of these gene mutations cause diabetes by making the pancreas less able to make insulin. The most common types of monogenic diabetes are neonatal diabetes and maturity-onset diabetes of the young (MODY). Neonatal diabetes occurs in the first 6 months of life. Doctors usually DIAGNOSE MODY during adolescence or early adulthood, but sometimes the disease is not diagnosed until LATER in life.Cystic fibrosis NIH external link produces thick mucus that causes scarring in the pancreas. This scarring can prevent the pancreas from making ENOUGH insulin.Hemochromatosis causes the body to STORE too much iron. If the disease is not treated, iron can build up in and damage the pancreas and other organs. |

Answer» Answer: Parallel RLC Circuit Analysis The Parallel RLC Circuit is the exact opposite to the series circuit we looked at in the previous tutorial although some of the previous concepts and equations still APPLY.
However, the analysis of a parallel RLC circuits can be a little more mathematically difficult than for series RLC circuits so in this tutorial about parallel RLC circuits only pure components are assumed in this tutorial to keep things simple. This time instead of the current being common to the circuit components, the applied voltage is now common to all so we need to find the individual branch currents through each element. The total IMPEDANCE, Z of a parallel RLC circuit is calculated using the current of the circuit similar to that for a DC parallel circuit, the difference this time is that admittance is used instead of impedance. Consider the parallel RLC circuit below. Parallel RLC Circuit parallel rlc circuit
In the above parallel RLC circuit, we can see that the supply voltage, VS is common to all three components whilst the supply current IS consists of three parts. The current flowing through the resistor, IR, the current flowing through the inductor, IL and the current through the capacitor, IC. But the current flowing through each branch and therefore each component will be different to each other and also to the supply current, IS. The total current drawn from the supply will not be the mathematical sum of the three individual branch currents but their vector sum. Like the series RLC circuit, we can solve this circuit using the phasor or vector method but this time the vector diagram will have the voltage as its reference with the three current vectors plotted with respect to the voltage. The phasor diagram for a parallel RLC circuit is produced by combining together the three individual phasors for each component and adding the currents vectorially. Since the voltage across the circuit is common to all three circuit elements we can use this as the reference vector with the three current vectors drawn relative to this at their corresponding angles. The resulting vector current IS is obtained by adding together two of the vectors, IL and IC and then adding this sum to the remaining vector IR. The resulting angle obtained between V and IS will be the circuits phase angle as shown below. Phasor Diagram for a Parallel RLC Circuit parallel rlc circuit phasor diagram
We can see from the phasor diagram on the right hand side above that the current vectors produce a rectangular TRIANGLE, comprising of hypotenuse IS, horizontal axis IR and vertical axis IL – IC Hopefully you will notice then, that this forms a Current Triangle. We can therefore use Pythagoras’s theorem on this current triangle to mathematically obtain the individual magnitudes of the branch currents along the x-axis and y-axis which will determine the total supply current IS of these components as shown. Current Triangle for a Parallel RLC Circuit Current Triangle for a Parallel RLC Circuit
Since the voltage across the circuit is common to all three circuit elements, the current through each branch can be found using Kirchhoff’s Current Law, (KCL). Rember that Kirchhoff’s current law or junction law states that “the total current entering a junction or node is exactly equal to the current leaving that node”. Thus the currents entering and leaving node “A” above are given as: kirchoffs current law
Taking the derivative, dividing through the above equation by C and then re-arranging gives us the FOLLOWING Second-order equation for the circuit current. It becomes a second-order equation because there are two reactive elements in the circuit, the inductor and the capacitor. |

Write the structures of alkenes, ethene and propene. What are they called?(1) Draw the structures of (1) diamond (ii) graphite.(c) What are hydrocarbons ? Write the structures of hydrocarbons with two carbon atomscontaining (1) carbon-carbon single bond (in) carbon-carbon double bond (ii) carbon carbontriple bond. |
|
Answer» Answer: As noted before, alkenes are HYDROCARBONS with carbon-to-carbon DOUBLE bonds (R2C=CR2) and alkynes are hydrocarbons with carbon-to-carbon triple bonds (R–C≡C–R). Collectively, they are called unsaturated hydrocarbons because they have fewer hydrogen ATOMS than does an alkane with the same number of carbon atoms, as is indicated in the following GENERAL FORMULAS |

18. i. Define work done and its SI unit.ii. Express work mathematically.iii. State the conditions for Zero work done.iv. Name the term used for the sum of kinetic energy and potential energy |
|
Answer» Answer: i) "WORK done is defined as the amount of force required to move one N (NEWTON) through the displacement of 1 M (metre). The SI unit of work is Joule which is denoted by the abbreviation ""J." Work is the measure that defines most of the things that is related to physics. ii) To express this CONCEPT mathematically, the work W is equal to the force f times the distance d, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is. W = fd cos θ. iii) ZERO work is done when the displacement of a body is zero or perpendicular (θ=900,cosθ=0) to the direction of force applied, then work done is zero. For example, if a person tries to push a wall, he is applying force yet the wall does not move, so the displacement of the wall is zero, and hence work done is zero. iv) The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy. This sum is simply referred to as the total mechanical energy (abbreviated TME). DO MARK ME THE BRAINLIEST AND FOLLOW PLEASE |

Answer» Answer: 1) A gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that enco'des the synthesis of a gene PRODUCT, either RNA or protein. During gene expression, the DNA is first copied into RNA. 2)Analogous organs are the opposite of homologous organs, which have similar functions but different origins. An example of an analogous trait WOULD be the wings of insects, bats and BIRDS that EVOLVED independently in each lineage separately after diverging from an ancestor without wings. 3)Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... Individuals that are poorly adapted to their environment are less likely to survive and reproduce. |
