What conclusion can be drawn about the number of elements the make up the majority of the world in which we live and the total number of elements identified on the Periodic Table?
Answers
Answer
Hey there
There are many elements in the universe, However, the universe is 98% hydrogen and hellium and only 2% other elements. This is due to the fact that hydrogen and helium and the easiest to make, it requires little energy. But in the universe, there are many potential elements some of which are not naturally occurring.
Hope it helped!
Answer: Greyfeatherlove has already posted a good answer. I'll add a few remarks.
Explanation: As noted by Greyfeatherlove, the universe is made up of lots of hydrogen and helium. Suns produce their light and energy when these two elements fusion in the hot cores of suns. The fusion releases energy and forms larger elements such as berylium, lithium, boron, carbon, nitrogen, and oxygen. Larger elements come from more energetic suns, while cataclysmic events such as supernovas have the energy to form the larger elelemnts found on the periodic table. Our sun is not large by univere standards, and is is thus more limited to making the smaller elements.
While I'm not sure what conclusion can be drawn withourt more data, it does make sense that life evolved around the more common elements manufactured by our own sun. This poses a great question that will surely be explored by George Lucas: what will evolve on planets around a more energictic sun thyat produced larger elements in abundance. Istead of carbon-based (atomic mass units: 12 AMU) life, should we expect silicon- (28 AMU) or tin-(119 AMU) based life instead?
We should also remember that many of the largest elements on the periodic table are either synthetic (man-made) or and/or very unstable. I wouldn't be surprised to find a real rockbiter (The Endless Story) pounding the mountains of a distant planet near a large star.

The toucan uses its long beak to reach fruits and berries growing on trees in the forest. The energy stored in the fruit and berries is passed on to the toucan when it is eaten. What is the source of energy for the fruits and berries growing on the trees in the tropical forest?
A: Soil
B. Sunlight
C. Heat
D. Water
Answers
Answer:
The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive. The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.
Plants use photosynthesis to convert light into cellular energy, which allows them to make “food” out of the water and nutrients from the soil.

Step 5: Set Up for Viewing. ...
Step 6: Set the Light Control. ...
Step 7: Focus the Microscope. ...
Step 8: Increase Magnification.
Answer:
Keep in mind this changes from microscope to microscope.
Explanation:
On most classroom microscopes, there will be two knobs on either side of the scope. These will increase or decrease the height of the "stage", which is how you "focus" the microscope. The larger knob will move the stage the most, and thus, is called the coarse focus. The smaller knob is called the fine focus, and, you guessed it, will move the stage the least. There are usually three "objective lenses". Each will have a different magnification and will be listed on the lens itself. It rotates around the "revolving nosepiece". MAKE SURE THAT THE SLIDE IS LOWERED BEFORE ROTATING THE LENSES!!!! If you don't you WILL break the slide and you WILL get death looks from the teacher.
On the stage, there are two clips. They move NOT up and down, but they spin. what you want to do is to move the slide into the clips. They will not break if you do not bend them more than what the slide will bend them to.
The technique for focusing the microscope is really easy once you do it a few times. After making sure that the microscope is plugged in and the light on and the slide and lens in the lowest position/magnification (!) move the coarse focus knob so that the object in the slide is just visible. Once you do that, from there use the fine focus knob to make the object most visible.
These instructions vary slightly from model to model of microscope, but the picture below is very accurate and everything I warned you about is for all microscopes.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
Answers
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
