Explanation:
Yeasts are unicellular microorganisms of the fungi kingdom that can digest sugars using both aerobic and anaerobic cellular respiration. In the below experiment, what by-product of this reaction causes the balloons to expand?
Answer:
This question is incomplete as it does not contain the representation of the experiment, however, based on general understanding, the answer is:
Carbon dioxide (CO2)
Explanation:
Yeasts, as stated in this question, are living unicellular organisms that belong to the KINGDOM FUNGI. They employ both the aerobic (with oxygen) and anaerobic respiration (without oxygen) in breaking down sugars. However, both methods of cellular respiration gives off CARBON DIOXIDE (CO2) as a byproduct.
Therefore, when a yeast is placed in a balloon in accordance to this experiment and is allowed to perform respiration either aerobically or anaerobically, it gives off CO2 gas, which causes the balloon to expand.

what is produced from covalent bonding
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability

How does carbon not get lost when it moves through the carbon cycle
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels. This extra carbon dioxide is lowering the ocean’s pH, through a process called ocean acidification. Ocean acidification interferes with the ability of marine organisms (including corals, Dungeness crabs, and snails) to build their shells and skeletons.
HELP ASAP PLEASE!! DUE IN 10 MINUTES !!! based on these results which statement correctly predicts what will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells
A:the red blood cells will absorb water and increase in size
B:the red blood cells will lose water and decrease in size
C:red blood cells will of first absorb water than lose water and maintain their normal size
D:the red blood cells will first lose water then absorb water and finally double in size
Answer:
The correct answer is - option B. the red blood cells will lose water and decrease in size.
Explanation:
The movement of the water takes place always from the high concentration region of solute to the low concentration of solute through a semi-permeable membrane. In this case, the representation is showing that placing the cell inside a solution with low concentration solute than the cell makes the cell increase the size, and placing it in a solution high concentration of solute makes it decrease in size due to the transfer of water from more water to the low water area.
Now placing the RBC in a solution with more salt concentration than the cell makes the solution hypertonic which means the solution has more solute concentration and less water so the water move from cell to the solution and cell will shrink and decrease in size.
What is the melting point of a substance
depending on what it is for water it is 32°F
steel is 2500°F
aluminum 1,221°F
zinc is 787.2°F
sorry i cant put all the melting points
unless u mean
Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.

Do you think tress could reduce the negative effects of climate change? why or why not
Answer:
Hi there, Here is what I think
Trees can't reduce the negative effects of climate change because climate change throws off their functions (ex. Trees' leaves fall during the fall season but if its a lot warmer close to summer weather during fall season) it can mess up the way they function at a certain point in the seasons with that trees won't be able to function properly if the weather changes all of a sudden from scorching hot summer to a blizzard all of a sudden which can kill trees. Trees can hibernate in the Winter and bloom around Spring/Summer time but if you have wintery weather during summer it will kill them. So no trees can't reduce the negative effects of climate changes hence why people are scared over climate change because if the trees die we can die too without the oxygen trees and other plants provide for us.

Main idea or the topic of finding the epicenter of an earthquake.
Answer:
Main Concept Seismology is the study of earthquakes, their effects, and seismic waves.
Explanation:
The earthquake epicenter is a point on the Earth's surface directly above an earthquake. Scientists determine the epicenter by studying the P waves and S waves produced by all earthquakes. P waves are compression waves and travel faster through the Earth than S waves.
