Life works at physiological pH and temperature. pH is the measure of concentration of hydrogen ion in a buffer that regulate the alkaline and acidic nature. High alkaline pH or acidic pH are not suitable for all bacteria to survive and grow. Hence we need to check the pH of any media.

Why an object with more mass requires more force to move it?

Because it is lighter.


What are the 17 parts of a microscope?

1.Eyepiece or ocular- upper optical component that further magnifies the primary images and bring the right rays into focus.2. Draw tube- it is the cylindrical structure which is used to support the eyepiece.3. Body tube- connects the ocular to the objective lenses.4. Coarse Adjustment Knob- It moves the tube up and down to magnify thespecimen.5. Fine Adjustment Knob- It adjusts the focus slightly, to make the image clear.6. Arm- basic frame to which the base, body and stage are attached and acts as aconnector between the base and the head of the microscope.7. Stage- Table of the microscope where the glass slide is placed and helps insupporting the specimen and helps you to keep the specimen on thecorrect location.8.Stage Clip- The stage clip hold the the specimen slide firmly on the stage and isneeded if the microscope is tilted.9. Glass Slide- is the place where specimen is place to view in the microscope.10. Inclination Joint- It allows one to tilt the upper part of the microscope so thatyou can view the specimen while seated.11.Base- it helps in supporting the microscope and contains the illuminator.12.Diaphragm- it controls the amount of light that passes through the stage and,consequently, through the specimen.13.Dust Shield- It protects the objectives from dust.14.Revolving Nosepiece- This is the part that holds two or more objective lensesand can be rotated to easily change power.15.Objectives- it gathers light from the sample or object under study.16.Mirror- is used to focus light up through the hole in the microscope's stage,or slide platform. The slides will contain a thin slice of materialthrough which the light can shine, to reveal the internal structure ofthe sample.17.Mirror Rack- holds the mirror in place.


Why do hot objects cool down more quicker than cool objects?

First off, it's just "quicker", never "more quicker" which is utter rubbish."Cool down" is another one of those rubber words and phrases that mean differentthings to different people as well as to the same people in different situations or atdifferent times. And "quicker" is another one as well, too.-- The rate of heat loss from an object depends on many things. One of them isalways the difference between the temperature of the object and the temperatureof its surroundings. So, if you have two identical objects that have different temperaturesand are in the same place, the one with the higher temperature will lose heat faster to thesurroundings.-- Another factor is the size and composition of the object, because they determinehow much actual heat energy the object contains. So, if two objects of differentsize and substance start out at different temperatures, there's no general way tosay which one will lose heat at a faster rate.-- The shape of the object also matters, because that involves the amount ofsurface area it has through which it can dump heat. So if you have two objects ofthe same volume, made of the same substance, and at the same temperature, theone with more lumps, bumps, wrinkles, and crinkles in its surface will lose heat at afaster rate than the smooth, spherical one. That's why auto radiators are coveredwith a structure that has millions of leaves and holes in it. It's also the main reasonwhy you try to curl up into a ball when you're cold.-- This is the story of how fast an object loses heat energy to its surroundings.That's NOT the same thing as how soon it reaches the temperature you want,which may be what you mean when you say "cool down more quicker".In general, there's no way to tell which object will reach the temperature you wantmore quicker. For example, a red hot cast iron pot off the stove may be cool enoughto handle long before a glass jug that was filled with boiling water.

How long to fall 3000 feet?

a max speed of 290kmh if you form you self lie a bullet but if you lie out 200kmhAnswer:There is no specific speed for free fall. It is dependent on many factors including the local attraction of gravity, air density, cross sectional area presented to the air flow and mass of the falling object. As a result cats can fall from tall buildings and not be hurt while people or ponies are reduced to a red mess.
