1. X-ray type electromagnetic radiation has higher energy than visible light and can pass through the human body.
2. Spectroscopy can provide composition and temperature information about objects in space.
3. Visible light is electromagnetic radiation with wavelengths between 380 nm and 700 nm.
4. Radio waves and ultraviolet light are examples of non-visible light.
5. When the emission line of helium from the galaxy is red-shifted as the galaxy is moving away from the viewer
The correct options for 1, 2, 3, 4 and 5 are A, (C and D), D, B and A respectively.
X-rays are valuable in medical imaging and other uses because they have more energy than visible light and can penetrate the human body.
By examining the light emitted or absorbed by the object, which forms a characteristic spectral pattern, spectroscopy can provide details about the composition and temperature of objects in space.
The human eye can perceive visible light because its wavelengths, which range from 380 nanometers to 700 nanometers, fall within this range.
Since their wavelengths lie outside the visible spectrum, radio waves and ultraviolet light are two examples of non visible light.
A galaxy is said to be moving away from the observer when the helium emission line from that galaxy is red-shifted in its spectrum. The Doppler effect, in which light emitted from objects moving away from the observer appears to be skewed toward longer (reddish) wavelengths, is what causes this redshift. This event is an important piece of evidence for the Big Bang theory and the expansion of the universe.
Therefore, the correct options for 1, 2, 3, 4 and 5 are A, (C and D), D, B and A respectively.

emily wants to know how green, blue and red color light affects plant growth compared to natural light. (Hint: what light affects the plant the most) Form hypothesis and design an experiment. Make sure identify the control, independent (manipulated) variable and dependent (responding) variable. Be detailed
Red and blue colored lights are most effective for plant growth.
Plant Growth is the dependent variable and light color is the independent variable. The rest are control variables.
A Control variable is the part of the experiment that we keep the same throughout all of the test subjects. An independent variable does not depend on other variables and a dependent variable does.
Allow me to explain. When we perform an experiment, many factors that can change the results, For this reason, it is common practice to keep many of them the same for all test subjects (In this case for all of the plants). This way we know that if changes are measured, they were not caused by these variables. These are what we call control variables.
An independent variable does not depend on other variables to remain the same. For example, the species of plant would be an independent variable, given that a plant cannot change its species because of other factors.
A dependent variable does change according to other variables and is often what we try to measure. For this example given, the dependent variable is how much the plant will grow with each colored light.
Knowing that plants rely on light to produce the energy needed to grow, we can hypothesize that applying different colors of light will have an effect on plant growth. To test this, we can create an experiment where we use:
Soilamount of wateramount of lightspecies of plantlength of experimentAs control variables.
One group of plants will have blue light, another green, and another red. We can identify the color of light as an independent variable.
Since what we seek to measure is plant growth, we identify this as our dependent variable and measure it for each plant after a set amount of time, to compare results.
With this, you can confidently identify the control, dependent, and independent variables and how to use them in your experiment.

Explanation:
Removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat
What is Deforestation?Deforestation also known as forest clearance is defined as the removal of forest or stands of trees from land that is converted to non-forest use in which forest land is converted into farms, ranches or urban may involve converting to use. The most concentrated deforestation occurs in tropical rainforests.
It occurs when humans remove or thin forests for timber or use land where trees stand for crops, grazing, extraction such as mining, oil, or gas, or as populations grow and people move. Development takes place in the form of migration.
Wildlife habitats are fragmented due to deforestation, where native species have to live on remaining habitat islands that are surrounded by disturbed land being used for agriculture and other uses.
Thus, removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat

Answer:
Its summer, winter, darker.
Explanation:
This is the answer I hope it helps you out.
Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.
What are seasons?A season exists the year that stands determined by particular climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each includes its light, temperature, and weather designs that repeat yearly.
Summer exists the hottest of the four temperate seasons, happening after spring and before autumn. At or centered on the summer solstice, the earlier sunrise and latest sunset happen, daylight hours exist longest and dark hours exist shortest, with day length falling as the season progresses after the solstice.
Winter, the coldest season of the year, between autumn and spring; the name arrives from an old Germanic word that represents “time of water” and guides to the rain and snow of winter in middle and increased latitudes.
Hence, Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.

Which of the following does NOT secrete hormones?
A. Ovaries
B. Skin
C. Adrenals
D. Pancreas
Answer:
skin acts as a protective barrier, therefore it does not secrete hormones
Skin does not secrete hormones. Thus, the correct option is B.
What are Hormones?Hormones may be defined as chemical substances that are produced by the organ system of an organism and transported at the site of action via the bloodstream. Hormones act as messenger molecules in the body.
Skin acts as the primary or first line of defense for the immune system. It does not secrete any hormones. It plays an important role in innate immunity. Ovaries are responsible for the secretion of hormones like estrogen and progesterone in females and regulate all the prospective consequences in the body of females.
The adrenal gland secretes hormones like cortisol and aldosterone which are steroid hormones. Such hormones are important in regulating metabolism, inflammation, immune functions, etc. The Pancreas secretes insulin and glucagon which play an active role in regulating the level of glucose in the blood.
Therefore, the skin does not secrete hormones. Thus, the correct option is B.

what process takes place at the boundary between the capillaries and the alveoli?
Answer:
Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Explanation:
This describes the exchange of gases in the lungs. When blood from the rest of the body gets to the lungs through the capillaries, oxygen flows from the alveoli which are tiny air sacs in the lungs, into the blood in the capillaries.
Carbon dioxide from the blood brought to the lungs will then flow into the alveoli which will then expel it through the nose. This repeated process ensures that the body keeps getting oxygen and expelling carbon dioxide.
Answer:
Exchange of Gas takes place in lungs between the alveoli and capillaries which are tiny blood vessels, placed at the walls of alveoli. The rate of diffusion depends on the thickness of the biological membrane which forms the boundary between the external environment and organisms.

Well this isn’t biology this is earth science but it doesn’t have the option.... 1. What geologic processes must have occurred for fossil ammonites (relatives to the nautilus that dominated oceans hundreds of years ago) to now be found in rocks at the highest mountains on Earth??
2. What would our planet look like if it contained no radioactive isotopes within it? What would it look like if radioactivity were producing twice as much heat within Earth’s interior?
The answers are that the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. With no radioactive isotopes, the Earth's geography would be vastly different and void of life. If radioactivity produced twice as much heat the earth would become unstable.
The discovery of fossil ammonites within rocks at the highest mountains on Earth is due to orogenic plate tectonics. Plate tectonics is the name we use to describe a process in which pieces of the earth's crust move and often slam into each other, causing one of these to pile onto the other.
This can lead to the formation of mountains and mountain ranges. This process helps to explain why fossils of ammonites known to dwell in the ocean can be found in mountains.
Radioactive isotopes, or better yet, the decaying of radioactive isotopes, are responsible for generating most of the Earth's internal heat. The internal heat of the earth is the driving force of plate tectonics and without it, much of the geological activities responsible for the earth's current geography would not have happened.
Mountain ranges would not have formedPlate tectonics would not have caused the formation of the continents we know todayThe earth would lack a magnetic field to defend against ionizing radiation from the sunLife would likely not have evolved.Radioactive isotopes were vital in allowing for the conditions of the earth at the time that life evolved, and the heat they produce allows the earth to have a molten core and thus generate a magnetic field for protection.
Now, if the heat produced by radioactive isotopes were to double, the Earth's internal temperature would nearly double. Since this heat is the driving force for plate tectonics, we can expect a sharp increase in the number of earthquakes and volcanic eruptions. These can, in turn, cause tsunamis and changes to the earth's global temperature. Mountains would form continuously and continents may break apart. This instability would make life on earth's surface improbable.
Therefore, the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. Without radioactive isotopes, the Earth's geography would be vastly different and void of life. Radioactivity producing twice as much heat would make the earth very unstable.
