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.

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.

18. Lab Summary - Explain how this experiment models a cell membrane. Use the
following terms in your explanation: selectively permeable, hypertonic, diffusion, indicator.
Answer:
Cell membrane is considered as boundary of the cell.
Explanation:
Cell membrane is the boundary of the cell which is selectively permeable that allows the micro-nutrients, water and gases like oxygen and carbondioxide etc through the process of diffusion. When the water goes inside due to diffusion it is the indicator that there is less quantity of water present inside the cell as compared to the external environment, this phenomena is called hypertonic.
Water covers most of Earth’s surface. The diagram shows the structure of a water molecule.

Which part of a DNA molecule is responsible for the direct coding of specific traits in an organism?
The number of hydrogen bonds that hold the strands of DNA together.
The number of hydrogen bonds that hold the strands of DNA together.
The number of carbons in the DNA molecule.
The number of carbons in the DNA molecule.
The sequence of nucleotide bases in the DNA molecule.
The sequence of nucleotide bases in the DNA molecule.
The sequence of phosphates along each DNA strand.
The sequence of phosphates along each DNA strand.
Answer: The sequence of nucleotide bases in the DNA
Explanation: The sequence of the nucleotides directly code for each trait. The genetic code is contingent on the sequence of the bases- if the order is changed (you will learn about this in genetic mutation), it would create a different code, which could possibly create a totally different gene depending on which base is changed.
Hope this helps,

What is DNA?Every living thing has self-replicating genetic material called DNA. It is a repository for all genomic data. It contains instructions that let organisms to develop, grow, survive, and reproduce. It's a big molecule with a genetic "code" in it. The foundation of human development is this genetic code. However, external factors including diet, lifestyle, and the environment influencing human evolution may have an impact.Nucleotide molecules, which make up DNA, are its constituent parts. The carbon-sugar group, phosphate group, and nitrogen base are the three elements that make up a DNA molecule. The four other nitrogen bases are adenine (A), cytosine (C), guanosine (G), and thymine (T).3 billion base pairs make up the distinctive human DNA, which is what makes it unique. But 99.9% of them are universal to humans. What information must be coded in order to support the growth and development of the organism is determined by the order of these bases. During transcription, when DNA is copied, a substance called as RNA is produced (Ribonucleic Acid). It is this RNA's job to convert genetic information from DNA to protein, which is then read by ribosomes.To learn more about DNA, refer to https://brainly.com/question/16099437

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.

The_______system is the main transport system of the human body. it is made up of the heart,blood,and blood vessels namely_____________. _______________,And________________.These vessels bring oxygen-rich blood also.Called_____________ to the different tissues in the body and transport_____________from the tissues to the lungs,in a process called circulation
Answer:
The circulatory system is the main transport system of the human body. it is made up of the heart, blood, and blood vessels namely arteries , veins And capillaries .These vessels bring oxygen-rich blood also Called veins to the different tissues in the body and transport blood from the tissues to the lungs ,in a process called circulation
Explanation:
ABOUT CIRCULATORY SYSTEM -: Blood vessels that carry blood away from and into the heart make up the circulatory system. Blood is carried away from the heart by arteries, and blood is carried back to the heart by veins. Oxygen, nutrients, and hormones are carried to cells by the circulatory system and waste materials, such as carbon dioxide, are extracted.
THREE MAIN BLOOD VESSELS -:
ARTERIES -: The arteries (red) bring oxygen and nutrients to your body's tissues, away from your heart. The aorta, the large artery leaving the heart, begins with the arteries. They carry blood rich in oxygen away from the heart to all the tissues of the body. As they carry blood further from the heart, they branch several times, becoming smaller and smaller.VEINS -: The arteries (red) bring oxygen and nutrients to your body's tissues, away from your heart. These are vessels of the blood that carry back oxygen-poor blood to the heart. When they get closer to the heart, the veins get bigger and bigger. The superior vena cava is a large vein which carries blood from the head and arms into the heart, and the inferior vena cava carries blood from the abdomen and legs into the heart. CAPILLARIES -: Capillaries are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow the passage of oxygen, nutrients , carbon dioxide and waste products from and to the tissue cells.BLOOD -: Blood circulates through the entire body through a network of vessels to provide oxygen and nutrients to individual cells and helps to dispose of metabolic waste. The blood around the blood vessels pumps the heart. Blood and circulatory processes circulate oxygen and extract carbon dioxide.

The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. The skin is only a few millimeters thick yet is the largest organ in the body. Your skin and its accompanying structures like hair and mucus are part of the body's first line of defense against pathogens. Describe two ways that the integumentary system protects your body systems from invasion.
Answer:
Explanation:
Skin is the first line of defense against various harmful activity due to contact with grit, microbes, or harmful chemicals. Sweat produces from sweat glands deters microbes from over colonizing the skin surface by producing dermicidin, which has antibiotic properties prevention infection.
The body has Heat and cold receptors are located in the skin. When the body temperature rises, the hypothalamus in the brain sends a nerve signal to skin glands that produces sweat and they release 1-2 liters of water per hour this cools the body.
The hypothalamus also beings about dilation of the blood vessels of the skin, this allow more blood to flow into those areas with high temperature causing the heat to be convected away from the skin surface.

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.

Carlos is asked by his teacher to closely observe the pixels on a television screen with a magnifying glass. He is told that each pixel emits one color of light at a time and that the colors emitted by adjacent pixels combine to create an image on the television screen. His teacher asks him to identify which colors the pixels emit. Carlos knows that any shade of paint can be made out of red, blue, and yellow paint. So he decides not to closely observe television and concludes that television pixels must emit red, blue, or yellow light to generate an image.
How did Carlos reach his conclusion?
A. He closely observed the colors of television pixels emitted.
B. He conducted a controlled experiment.
C. He proved that the properties of light are the same as those of paint.
D. He let his prior expectations bias his investigation.
Answer:
