It introduces a diverse array of bacteria, algae, and invertebrates to the closed marine environment and functions as a superior biological filter
Length: The most common units that we use to measure length in the metric system are the millimeter, centimeter, meter, and kilometer. The millimeter is the smallest commonly used unit in the metric system
Mass: Kilogram.
Liquid volume: The basis of fluid volume units for the metric system is the liter. A liter is about the same as one quart.
- The independent variable in an experiment is the variable whose value the scientist systematically changes in order to see what effect the changes have.
- A dependent variable is what the experimenter observes to find the effect of systematically varying the independent variable.
- Experimental constants are values that do not change either during or between experiments.
- A controlled variable is a variable that could change, but that the experimenter intentionally keeps constant in order to more clearly isolate the relationship between the independent variable and the dependent variable.

Answer:
using higher concentration of the nucleophile
Explanation:
In SN2 reaction, the attack of the nucleophile on the substrate occurs simultaneously as the leaving group departs. The entering group normally attacks through the back side of the molecule. The reaction is concerted and bimolecular. This implies that the concentration of the nucleophile is important in the rate equation for the reaction. Hence increasing the concentration of the nucleophile will increase the rate of SN2 reaction.
Halogens. Ex. fluorine can be the gas,bromine can be the liquid, and iodine could a solid all under room conditions.
The density of a glass helps determine the weight of the optical assembly and, along with lens diameter, becomes critical for weight sensitive applications.
