Chapter 01: Cellular Biology MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus, the nucleus should be observed. A single circular chromosome ca...

Acute and Critical Care Medicine- Background When a patient is sick enough to require an advanced level of care, they are assessed for risk and admitted to either the general hospital unit (acute care) or the critical care/intensive care units (ICU). If their illness has a high probability of imminent or life-threatening deterioration, treatment in the ICU is needed. The goal of critical care treatment is stabilization. If the illness is not as imminent, treatment in a general medical (acute) c...

Note the various forms of N -:- 1. Ammonium (NH4+) cation in the soil solution and fixed in secondary clays 2. Nitrate (NO3-) anion in the soil solution 3. Organic N in the soil 4. Ammonia (NH3) gas (released to atmosphere) 5. NO, N2O, N2 gases (released to atmosphere) anion- nitrogen -:- it is not held by soil colloids and can be lost from the soil through leaching. However in well aerated soils (plenty of oxygen), most of the NH4+-N (applied for example as fertilizer) changes to the...
