why is the skin known to be the body's most important nonspecific defense ?
Answer:
Explanation:
The body's most important nonspecific defense is the skin, because it acts as a physical barrier to keep pathogens out. Even openings in the skin (such as the mouth and eyes) are protected by saliva, mucus, and tears, which contain an enzyme that breaks down bacterial cell walls.

Answer:
Robert Hooke
I hope this helps you :)
Roobert Hooke first scientist to observe cells using a microscope.
Thus, Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.
Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.
The microscope can produce a static image, similar to a traditional scanning electron microscope, or a dynamic image, like traditional optical devices.
Thus, Roobert Hooke first scientist to observe cells using a microscope.

A researcher wanted to know if attractive people are more likely to receive help when in need, compared to unattractive people. if the investigator randomly assigned participants to groups that involved an attractive confederate versus an unattractive confederate, such a study would involve 'imdependent' variable.
What is the factor on which physical activities depend?Physically attractive defendants will receive shorter prison sentences than physically unattractive defendants. In an experiment, the hypothesis is an assumption that the researcher makes and that will be tested during the execution of the experiment. This assumption is created from the researcher's observation about a certain situation or element.
In the case of the experiment presented in the question above, we can see that the researcher observed that physically attractive or unattractive defendants have different sentences after the trial. From this, this researcher created a hypothesis, he assumed, that physically attractive defendants will receive lower sentences than defendants who are not physically attractive.
Therefore, A researcher wanted to know if attractive people are more likely to receive help when in need, compared to unattractive people. if the investigator randomly assigned participants to groups that involved an attractive confederate versus an unattractive confederate, such a study would involve 'imdependent' variable.

What is respiration?
Answer:
Respiration is the act of respiring; inhalation and exhalation of air; breathing. the sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off.
in other words
a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

1) What is the proper way to carry a microscope? 2) What is the typical magnification of an ocular lens? What other magnifications are possible? 3) What are the magnification abilities of each of the objective lenses? What is the total magnification with each objective? a) Scanning (small lens), red ring = b) Low-power (medium lens), yellow ring = c) High-power (large lens), blue ring = d) Oil immersion (largest lens), white ring = 4) Why do you use immersion oil with 100% objective lens? 5) What is the total magnification of a sample with an ocular lens power of 15X and using a 40X objective lens? 6) What is a diaphragm? What does it do?
the objective and ocular lenses are responsible for magnifying the image.
so for 10x objective and 10x ocular
total magnification= 10x10= 100x(this means that the image being viewed will appear to be 100 times its actual size)
a)scanning(small lens),red ring=4x or 5x
b)low power (medium lens), yellow ring = 10x
c) high power (large lens),blue ring = 40x
d)oil immersion (largest lens),white ring = 100-250x
4.immersion oil helps to focus on lighting
5. total magnification=15x40 =600x
6. diaphragm controls the amount of light reaching the specimen.
They control both the focus and quantity of light applied to the specimen.

What type of cells have a high concentration of mitochondria?
Answer:
It is important to point out that muscle cells have a very high concentration of mitochondria that produce ATP. Your muscle cells need a lot of energy to keep your body moving. When your cells don't get enough oxygen, they do not make a lot of ATP.
Explanation:
Muscle cells have a high concentration of mitochondria.
Regulation of metabolic enzymes in skeletal muscle occurs in response to changes in ATP demand, substrate availability, and in response to hormonal and neural stimulation.
The muscle fiber is an elongated cell whose length can reach several centimeters.
The sarcoplasm of a muscle fiber contains many mitochondria.
They are those that produce energy (ATP) directly usable by the muscle fiber to contract its myofibrils, which are the contractile elements of skeletal muscle cells.
Therefore, we can conclude that adenosine triphosphate (ATP) is the basic source of energy for muscle contraction is ATP and muscle cells have a high concentration of mitochondria.
