Why is it one needs more illumination when using the higher levels of magnification?

It's actually simple: The more the magnification, the smaller a "picture" of the available light you are getting - hence the more magnification, the darker the image looks. It works the same way with an astronomical telescope: The more magnification you use (assuming the objective lens doesn't change) the dimmer the object gets. To put it another way - there is a big difference between how high a magnification you are using, and how much light is reaching your eye.

What is the difference between substage and epi-illumination?
substage needs a condenser, and passes light through the tissue section from below. Epi-illumination reflects light off of the specimen from behind
What are the five levels of maslows hierarchy?
Maslow's Heirarchy consists of five different levels that are often show inside of a multi colored pyramid. The five levels are basic needs, safety needs, social needs, esteem needs, and self actualization.
Why do multicellular organisms needs levels of organization?
Learn.
Why is your basic needs more important than your higher needs?
Because without having your basic needs met you can't survive for too long.
Why are microorganisms important in ocean food chains?
Microorganisms such as algae are photosynthetic and convert energy from the sunlight into usable energy for organisms. Since organisms are inefficient at converting energy when consuming organisms, there needs to be a constant inflow of energy to sustain higher levels of the food chain. The loss of energy also explains why there are lesser numbers of organisms higher up on the food chain.

How do microscopes differ in magnification and resolution?
Microscopes differ in magnification by how much they can enlarge an image, while resolution refers to the clarity and level of detail in that image. Higher magnification allows for greater detail to be seen, but without sufficient resolution, the image may appear blurry or undefined. It's important to consider both magnification and resolution when choosing a microscope for specific scientific or research needs.
What are the four levels of Abraham Maslow's Hierarchy of Needs?
The four levels of Abraham Maslow's Hierarchy of Needs are: physiological needs (food, water, shelter), safety needs (security, stability), love and belongingness needs (relationships, connection), and esteem needs (respect, recognition). These levels must be met in sequence, starting from the basic physiological needs before progressing to higher levels of self-actualization.
Define of Maslow's hierarchy of needs?
Maslow's hierarchy of needs is a psychological theory that categorizes human needs into five levels: physiological, safety, love/belonging, esteem, and self-actualization. According to the theory, individuals prioritize fulfilling lower-level needs before moving on to higher-level needs.
What are the different levels of individual needs?
the different levels of individual needs are; -psychological needs -safety needs -social needs -esteem needs and self actualization...
What is the difference between substage and epi-illumination?
substage needs a condenser, and passes light through the tissue section from below. Epi-illumination reflects light off of the specimen from behind
The base of the Maslow hierarchy is?
The base of Maslow's hierarchy of needs is physiological needs, which include basic requirements for survival such as food, water, shelter, and rest. These needs form the foundation of the hierarchy and must be satisfied before an individual can progress to higher levels of needs.
What is a Low Illumination Camera?
The "Illumination" is measured by "foot candles." According to Engineering Tool Box: "A foot candle is actually one lumen of light density per square foot, one lux is one lumen per square meter." Engineering Tool Box also states that the recommended indoor illumination level is 500 to 1,000 lux. However, the light level may increase to 2,000 in areas where detailed work is being done, such as in a workshop or office. Classrooms and some offices may have lux levels of 250, and the areas with lux levels below 250 are considered "Low Illumination". For example, Most homes, warehouses and theaters have lux levels around 150; A working area where visual tasks are sometimes performed; like a storage closet, may have a lighting level of 100 to 150 lux. Areas where individuals spend a short amount of time and do not undertake visual tasks may have light levels of 50 to 100 lux. Public areas that have dark surroundings, like parking garages, may have lux levels of 20 to 50. Low Illumination Camera which can work in weak light condition is a kind of Hidden and (or) Security Camera, involving Moon type, Star type and IR type. Such high sensitivity cameras as Moon grade and Star grade can normally work in tiny light condition and 1~3 Lux is the general illumination. Moon type: normal work needs around 0.1 lux illumination. Star type: normal work needs below 0.01 lux illumination. IR type: IR light source, even can image Black/White picture in 0 lux condition.

How do the çalorie needs of a 16 year old female compare with those of a 16 year old male?
If the weight and activity levels are about the same a 16 year old male will usually have a higher calorie need due to higher muscle mass.
What type of needs does he call the four lowest levels on his hierarchy?
He called them "deficiency needs".
