please help asap ill give that brain thing if you have a correct answer tysm:)

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.

Explanation:

goodluck yall

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.

Answer:

b.synthetic;oil

Explanation:

oil makes plastic

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.

Answer:

B.  preservation of advantageous genetic mutations

Explanation:

The process of natural selection involves the preservation of advantageous genetic mutation in a given population.

Natural selection is one of the key factors that ensures the evolution of organisms.

Merry Christmas and Happy Holidays!

Answer: The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP. The electron transport chain works as a proton pump: it pumps hydrogen ions (protons) through the membrane, and only allows them back through a protein (ATP synthase) which makes ATP.

Hope this helps......... Stay safe and have a Merry Christmas!!!!!!!

I just want to say something... My account got deleted yesterday and i'm very upset because i had over 600 friends, 7,00 points, and 38 brainiest answer... I would love it if i got at least 15-20 friends by Christmas.

Answer:

Explanation:

I really dont know, but I think its correct

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.

Answer:

recombination resulting in replacement of the wild type with the mutated gene

Explanation:

Recombination is a process of the formation of new alleles when the original ones are broken down into bits and then ‘recombined’.

When mutation of a cloned gene occurs and the mutated gene is reinserted into a cell, the mutated sequence gene function will have to be disabled which involves recombination resulting in replacement of the wild type with the mutated gene.

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.
