What happens when a low air pressure system meets a high air pressure system?
A) The temperature of the air drops to below freezing.
B) The air moves to the low pressure system, creating wind.
C) The precipitation is removed from the air.
D) The air starts blowing in an easterly direction.

Answers

Answer:

High in the atmosphere, air pressure decreases. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

B) The air moves to the low pressure system, creating wind.

What is air pressure?

When a low air pressure system meets a high air pressure system, air from the high pressure system flows towards the low pressure system in an attempt to balance the pressure.

This movement of air creates wind. The stronger the difference in pressure, the stronger the wind. This is why wind speed is often stronger in areas with a large contrast in pressure, such as near fronts where a low pressure system meets a high pressure system.

Answers

Answer:

ll living things are composed of cells. This is one of the tenets of the Cell Theory, a basic theory of biology. This remarkable fact was first discovered some 300 years ago and continues to be a source of wonder and research today. Cell biology is an extremely active area of study and helps us answer such fundamental questions as how organisms function. Through an understanding of how cells function we can discover how human ailments, such as cancer and AIDS, can be possibly treated.

THE CELL THEORY

All life is composed of cells

Cells are the fundamental units which possess all the characteristics of living things

New cells can only come into existence by the division of previously existing cells

Notice that this scientific concept about life is called a theory. In science, unlike the layman’s definition, the word theory is used for a hypothesis about which there is a large body of convincing evidence. Under experimental conditions all observations have thus far confirmed the theory. The evidence that helped formulate the theory was obtained using the microscope. The microscope is of enormous importance to biology and has extended our ability to see beyond the scope of the naked eye.

When we look at cells under the microscope, our usual measurements fail to work. In science, the metric system is used to measure objects and, as you will see, is vastly superior to our antiquated English system of measurement. Here are the basic units:

Length Volume Weight

1 meter (m) 1 liter (L) 1 gram (g)

1 millimeter (mm) = 0.001 m or 10−3 m or 1/1,000 m 1 milliliter (ml) = 0.001 L or 10−3 L 1 milligram (mg) = 0.001 g or 10−3 g

1 micrometer (mm)= 0.000001 m or 10−6 m or 1/1,000,000 m 1 microliter (ml) = 0.000001 L or 10−6 L 1 microgram (mg) = 0.000001 g or 10−6 g

1 nanometer (nm)= 0.000000001 m or 10−9 m or 1/1,000,000,000 m  

There is also a different scale for temperature: Celcius.

100˚ Celcius (C) = water boiling (equivalent to 212˚ F)

0˚ C = water freezing (equivalent to 32˚ F)

Converting between units can be confusing. The most effective way to do this is by using conversion factors and canceling units. For example, if you want to know how many liters are in 425 milliliters, you can set up a simple equation that looks like this.

[latex]\displaystyle{425}\text{ ml}\times\frac{1\text{ liter}}{1000\text{ ml}}=\frac{425\text{ ml}}{1000\text{ ml}}=0.425\text{ L}[/latex]

PRACTICE

1.2 mm = ________ mm 0.224 m = ________ mm 225 nm =___________mm

0.023 L = ________ ml 750 ml = _________L 50 ml       =___________ L

Part 1: Microscope Parts

Nikon microscope with parts labelled. The compound microscope is a precision instrument. Treat it with respect. When carrying it, always use two hands, one on the base and one on the neck.

The microscope consists of a stand (base + neck), on which is mounted the stage (for holding microscope slides) and lenses. The lens that you look through is the ocular (paired in binocular scopes); the lens that focuses on the specimen is the objective.

Your microscope has four objectives of varying magnifications (4x, 10x, 40x, and 100x) mounted on a revolving nosepiece. The 100x objective is a special oil immersion objective that needs to be used with oil—we won’t use the oil immersion objective for this course.

Positioning the specimen requires that you turn the mechanical stage controls, which operate the slide bracket on the surface of the stage. One control moves the specimen in the x-direction, and the other moves the specimen in the y-direction.

Focusing on the specimen is achieved by knobs that move the stage up and down, so that it is closer or farther from the objective. There are two knobs, an outer coarse focus and an inner fine focus.

The substage condenser directs light through the slide into the objective. An iris diaphragm on the substage condenser controls the amount of light reaching the objective, and also affects the contrast of the specimen.

Part 2: Magnification

The compound microscope has two sets of lenses; the ocular lens (or eye piece) which magnifies an object 10 times its normal size, and the objective lenses located on a revolving nosepiece. Rotate the nosepiece and notice how each objective lens clicks into place. Each objective lens has a different magnification of power written on it (such as 4, 10, 40, or 100). This number is the power of magnification for each of the objective lenses. For total magnification multiply the ocular power (10x) times the objective lens that is in place. For example, if you have a 10x ocular and a 10x objective, the total magnification is: 10x × 10x = 100x.

How does the pacific ocean help explain the weather differences between San Francisco and Kansas city? If possible, discuss your answer.

Answers

The Pacific Ocean is near San Francisco, the high heat capacity of water absorbs large amounts of heat. The humidity in Kansas City is higher, water in the air absorbs heat which makes people feel more hot.

The presence of pacific ocean causes weather differences between San Francisco and Kansas city.

The pacific ocean helps in explaining the weather differences between San Francisco and Kansas city because San Francisco is located near the pacific ocean which has great effect on its climate while on the other hand, Kansas city is located far from the pacific ocean which have less or no effect on the climate of the Kansas city.

San Francisco has hot, dry summers and cool, rainy winters due to presence near the pacific ocean whereas the climate of Kansas City has cold winters and hot summers with frequent thunderstorms so we can conclude that the presence of pacific ocean causes weather differences between San Francisco and Kansas city.

False. The Calvin cycle is also known as the "light-independent reaction" because it does not require sunlight. The Calvin cycle is the process that plants use to convert carbon dioxide into glucose, and it takes place in the stroma of the chloroplasts. The light-dependent reactions, on the other hand, occur in the thylakoid membranes of the chloroplasts and require sunlight to produce energy in the form of ATP and NADPH, which are used to power the Calvin cycle.
