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.

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.

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.
Unlike green bacteria that produce oxygen, the purple bacteria performed a type of photosynthesis that produced sulfur. If the purple bacteria had outlived the green bacteria, how would Earth’s atmosphere be different today?
Answer:
Explanation:
About 21% of Earth's atmosphere is oxygen, and most of the rest is nitrogen. ... the evolution of Cyanobacteria, a group of single-celled, blue-green bacteria. ... Today, Cyanobacteria can be found almost everywhere on Earth — likely right ... the genetic machinery for photosynthesis that we'd expect to see if they had lost this ...

Which Image is correctly labeled prokaryotic cell? A: Image 1. B: Image 2. C: Image 3.
D: Image 4.
Answer:
Image 3
Explanation:
Prokaryotic cells are single-celled organisms that lack membrane-bound organelles, including a defined nucleus.
The only cell without membrane-bound organelles is image 3
Image 1 is a single-celled eukaryotic organism, probably a paramecium.
Image 2 is a plant cell (has a cell wall)
Image 3 is a bacterium

Why are viruses known as parasitic?
Answer:
Explanation:
All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.
Please help I do not know the answer to this question
Answer:
A
Explanation:
Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes.

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.
