Answer:
The pieces can be represented by genes
Explanation:
It has been shown that the human genome contains more than 30 thousand protein‐coding genes, as well as transposable elements, repetitive and non-coding RNA sequences. These protein-coding genes are in turn composed of coding regions (exons) separated by non-coding regions (introns). The analysis of the human genome enables the scientists to identify genes associated with specific signaling network pathways and diseases.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

Can this graph help you explain why the amount of carbon dioxide in the air of the biodome decreased?
Answer:
The ecosystem helps with the different chemical energy that needs to be broken up so that it can help with cellular respiration and the (EMS) also helps with it as well. The carbon dioxide helps the plants to keep growing to get big and strong. Photosynthesis also helps let them know what they are doing while they are growing. They can have high or low carbon and the color can be green-yellow or blue. The biotic matter can help with many different things with the material of clothing and abiotic matter is what soil is made of. The system is being taken care of by many different things and they are soil. The consumer is helping keep the environment for the producer plants to keep growing. The decomposer plants are helping keep the plants that die and try to get them to live again. The abiotic matter and carbon dioxide were decreasing the cellular respiration and it also decreases the carbon dioxide overall it also helped the (EMS) to produce the many different types of things that they might have needed to keep growing so that they would get everything that they needed to keep the growing so that they can compose more of what they would need to keep them growing. What causes the carbon dioxide to collapse or decrease was all of the plants release energy during the process of growing and it also helps the produce (EMS) and many other things. That also means that they can increase or decrease. the carbon dioxide decreased because all of the decomposers decreased so that somewhere there was a decrease somewhere with the cellular respiration.
Explanation:
Yes, it can be explained by biodome population data. As there is a decrease in the carbon dioxide there is a decrease in the decomposers.
What is a biodome poulation?A biodome population is a self-sustaining human-made environment that is self-contained. It can also be said that it is a man-made built ecosystem. This ecosystem consists of forms of life. Fungi, bacteria, plants, insects, fishes, and animals are put together.
The biodome can be humid, temperate, or tropical biodome. This is also known as man-made habitat. The presence of water bodies is also mandatory for the biodome. Examples of biodomes are maple forests and tropical forests. These biodomes can be visited and studied.
Therefore, the biodome is similar to the natural habitat.

Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen windows, and one on the mantel in the living room. Each plant has the same pot and the same soil, and Lauren gives each plant the same amount of water. Which is the independent variable?
Answer:
First, before determining which variable is which, we go over the definition of each. The independent variable is the one which is intentionally changed in order to investigate its effect on the dependent variable. The dependent variable is monitored and changes occur in it due to the changing conditions of the independent variable. In this case, the location of the African violets is the independent variable as it is intentionally changed, while the rate of growth of the African violets is the dependent variable as it is being measured.
Why do you think the Arecibo message and the beacon in the Galaxy were broadcast in binary code?
Answer:
Hi!
The Arecibo message and the beacon in the galaxy were broadcast in binary code because binary is a universal language that can be easily understood by any intelligent beings, regardless of their language or culture. Binary code consists of only two symbols, 0 and 1, which can be used to represent any information, including letters, numbers, and instructions. This makes binary an ideal choice for transmitting messages over vast distances, as it is less prone to errors and can be decoded with a high degree of accuracy.

Explain how deep currents form and move in the ocean.
Use complete sentences.
This is science 6th grade. Amplify.
Deep ocean currents are formed by differences in water density, which are usually caused by differences in temperature and salinity. The density of seawater increases as the temperature decreases and the salinity increases. This means that colder and saltier water is denser and sinks to the bottom of the ocean, while warmer and less salty water is less dense and rises to the surface.
These differences in water density set up a circulation pattern in the ocean known as thermohaline circulation. In this circulation, cold and dense water sinks in the polar regions and flows towards the equator, where it slowly rises to the surface. This creates a global conveyor belt of deep ocean currents that circulate water around the world's oceans.
The movement of deep ocean currents is also influenced by the Earth's rotation and the shape of the ocean basins. The Coriolis effect, which is caused by the Earth's rotation, deflects deep ocean currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The shape of the ocean basins also influences the movement of deep ocean currents, as currents tend to flow around the edges of the basins and are deflected by land masses and underwater ridges.
Overall, deep ocean currents are an important part of the global ocean circulation system and play a crucial role in regulating Earth's climate by transporting heat and nutrients around the world's oceans.

Peptic ulcers are sores in the lining of the stomach, they are cause by bacterial infection. The bacteria increases the acid in the stomach and ears away at the stomach linings, which makes sores. When this happens, what tissue does the acid remove?
Answer:
Peptic ulcer disease occurs when open sores, or ulcers, form in the stomach or first part of the small intestine. Many cases of peptic ulcer disease develop because a bacterial infection eats away the protective lining of the digestive system. People who frequently take pain relievers are more likely to develop ulcers.
Explanation:
Answer:
The acid in peptic ulcers can damage stomach tissue.
Explanation:
Ulcers form when the intestine or stomach's protective layer is broken down. When this happens, digestive juices - which contain hydrochloric acid an anzyme called pepsin - can damage the intestine or stomach tissue.

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.
