The Normal Cell Cycle - -The cell cycle refers to the ordered series of processes of DNA replication and mitosis, or cell division -Cell nucleus regulates these processes by gathering and processing complexes molecular information Interphase and Mitotic Phase - Cell division produces two identical cells through these two major phases During interphase: - Cell grows and DNA is replicated through the following three steps: 1: First growth phase (G1 or first gap) 2: Synthesis phase (...

What happens when an object falls and there's no air resistance? - Energy lost from the g.p.e store = energy gained in the kinetic energy store What does air resistance do when acting against falling objects? - It causes some energy to be transferred to other energy stores e.g. the thermal energy stores of the object and the surroundings Elastic potential energy formula - E=1/2ke² E.P.E(J) = 0.5 x spring constant(N/m) x extension²(m) What is SHC? - The amount of energy needed to r...

Equilibrium Price - The price that balances quantity supplied and quantity demanded Equilibrium Quantity - The quantity supplied and the quantity demanded at the equilibrium price Equilibrium - A situation in which the market price has reached the level at which quantity supplied equals quantity demanded Equality - Those benefits are distributed among society's members Efficiency - Society that is getting the maximum benefits from its scarce resources "The cost of something ...

Accuracy - describes how close the samples are to the true value of the population. Dependent variable - the outcome variable and is the variable that is not manipulated by the experimenter One tailed test - you test the hypothesis in one direction (the parameter is larger/smaller than the parameter specified in the null hypothesis) Accuracy can be improved - through randomization (random sampling). Precision - describes how disperse the individual observations are from each other....

According to the WHO, prevention of mental health disorders is a public health priority. Explain why a focus on prevention is needed to reduce the burden of mental health disorders - The burden of disease is high. High psychological, economic and social burden. You can only avert part of the burden with treatment. Current limitation in treatment, only sustainable method is prevention. There are also new and cheaper options Give an example of a universal, a selective and an indicated preventiv...

X-ray locks in NOMAD Pro 2 automatically engage after 2 hours of inactivity. - False Because NOMAD Pro 2 shielding limits the exposure, it is permissible to have other people In the exam room during exposures without any precautions. - False The NOMAD Pro 2 should be routinely cleaned using disinfectant wipes, or some other non- acetone cleaner to maintain cleanliness. - True The backscatter shield is adjustable to accommodate positioning devices and other special needs but if the back...
