The life of a red blood cell is one of repetition and of enrichment. We begin at the heart, as an un-enrichied blood cell, we travel through the ventricles and into the lungs, we travel along the lung sack and become enriched with oxygen, the arteries are slow and calm as the human is not moving too often, we travel to the legs where we enrich the muscles through the capillaries and enter the veins which will bring us back to the heart and continue the cycle again.
Explain why light traveling through an eyeglass lens refracts.
Answer:
Explanation:
Since the light ray is passing from a medium in which it travels relatively slow (more optically dense) to a medium in which it travels fast (less optically dense), it will bend away from the normal line. ... Rather, these incident rays diverge upon refracting through the lens.
Light traveling through an eyeglass lens refracts because of the difference in the refractive index of the lens material and the air that is present surrounding it, as light bends differently in different mediums.
What is the significance of the light refraction?Light traveling through an eyeglass lens refracts because of the difference in the refractive index of the lens and the air, so when light enters something with a different refractive index, such as an eyeglass lens, it slows down and changes direction, and the difference in thickness in the eyeglass causes light rays entering the lens from different angles to be bent differently.
Hence, light traveling through an eyeglass lens refracts because of the difference in the refractive index of the lens material and the air that is present surrounding it, as light bends differently in different mediums.

What do vehicles that run on hydrogen fuel cells emit?
Answer:
Hydrogen-powered fuel cell electric vehicles emit none of these harmful substances—only water (H2O) and warm air
Explanation:
transportation sector accounts for about one-third of U.S. carbon dioxide emissions, using these sources to produce hydrogen for transportation can cut greenhouse gas emissions
Answer:
"Apart from fumes, there is also no air pollution from hydrogen fuel cell cars at all. Conventional cars emit gases that contribute to ozone layer depletion and also to the development of acid rain. Thus, there are many issues to the use of conventional gas that use fossil fuels which could be avoided by using hydrogen cars instead."

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.
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.

The pressure zone that separates the Westerlies and Easterlies in the northern and southern hemisphere is called the___________
Answer:
intertropical convergence zone
Explanation:
At the intertropical convergence zone near the equator, where the trade winds from the northern and southern hemispheres converge, the air rises, producing a belt of weak, light, shifting winds called the doldrums.
The pressure zone that separates the Westerlies and Easterlies in the northern and southern hemispheres is called the Subpolar lows.
In the Subpolar regions (60° to 65° lat North/South), the rotation of the earth creates a low-pressure belt in this area.The subpolar low is a region of winds that circles the Earth at the subpolar low-pressure belt.In conclusion, the pressure zone that separates the Westerlies and Easterlies in the northern and southern hemispheres is called the Subpolar lows.Learn more in:

Mammals
Abiotic factors
Heterotrophs
Biotic Factors
All of the trees in an ecosystem are examples of the biotic factors in an ecosystem (Option D).
What are biotic factors?Biotic factors refer to the living components of an ecosystem, including all of the organisms that live within it. This can include plants, animals, fungi, and microorganisms. These living components interact with each other and with the non-living components of the ecosystem, known as the abiotic factors, to shape the ecosystem and maintain its balance.
For example, plants play a crucial role in the ecosystem by producing oxygen through photosynthesis and providing food and habitat for other organisms. Similarly, predators play an important role in maintaining the balance of populations of prey species. Biotic factors can also influence the physical environment, such as through the creation of soil through the decomposition of organic matter by microbes and other organisms.

The diatoms below are magnified 400x. To find the total magnification while looking under a microscope, you must multiply the power of the eyepiece lens by the power of the ? *
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]

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.
