you have two bean burritos with the same ingredients. One burrito weighs 0.3 pounds, while the other weighs 0.5 pounds. After microwaving each of them for one minute, which burrito will be hotter? Explain your answer.
Answers
Answer:
the one that weighs less
Explanation:
the one that weighs less has less of the amount of ingredients in it which takes less long to cook and heats up faster
Answer:
0.3 pounds
Explanation:
I say that because since there is less weight on one of them, it doesn’t have to be cooked as long, or else it may get cooked TOO uh since it weighs less, while the other one may be cooked perfectly since there is more to cook.

Answer:
true
Explanation:
False. At the freezing point, the particles in an object have some kinetic energy.
False. On the Celsius temperature scale, there are negative numbers.
True. The more particles an object has at a given temperature, the more thermal energy it has.
False. Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
False. When heat is absorbed by an object, the speed of the particles in the object is changed.
Explanation:
The temperature is defined as the measure of hotness and coldness.It is measured in terms of degrees Celsius, Kelvins, degrees Fahrenheit.There are negative numbers on the Celsius temperature scale and Fahrenheits temperature scale but not on the Kelvin temperature scale.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature. The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.The object with more mass will have more particles and more will be the kinetic energy associated with the particles.When heat is added to an object to raise its temperature the kinetic energy of the particles increases. As kinetic energy is directly linked with speed or velocity.So from this, we can conclude that :
At the freezing point, the particles in an object have some kinetic energy.
On the Celsius temperature scale, there are negative numbers.
The more particles an object has at a given temperature, the more thermal energy it has.
Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
When heat is absorbed by an object, the speed of the particles in the object is changed.

Which three organs are part of the digestive tract?
A) salivary glands, gall bladder, appendix
B)teeth, tongue, mouth
C)esophagus, stomach, small intestine
D)esophagus, liver, pancreas
Answers
Answer:
C
Explanation:
Due to the stomach and small intestine being part of the digestive tract and the esophagus allowing food, liquids and air to enter the torso
Esophagus, stomach, small intestine are part of the digestive tract. Therefore option C is correct.
The digestive tract, also known as the gastrointestinal tract, is responsible for the process of digestion in the human body. It consists of a series of organs that work together to break down food and absorb nutrients.
The three organs that are part of the digestive tract are the esophagus, stomach, and small intestine.
The esophagus is a muscular tube that connects the mouth to the stomach and helps in the transportation of food. The stomach is a sac-like organ that mixes and churns food with digestive enzymes and acids.
The small intestine is a long tube where the majority of digestion and absorption of nutrients occurs.
Therefore option C esophagus, stomach, small intestine is correct.

How do cells obtain energy?
Answers
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cells have an organelle known as 'mitochondria' which has ATP molecules in it. These ATP molecules generates energy for the cell to function properly.
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.
This process is called 'cellular respiration'.
The process is happens in all the cells in our body.
Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

3. If a cell could perform both cellular respiration and fermentation, which process would benefit the cell more?
Answers
Answer:
1.NADPH2 and FADH2 , and O2
Explanation:
NADPH2 and FADH2 get oxidized in the electro transport chain into NADP+ and FAD+ and water and oxygen and yield 3 ATP molecules and 2 ATP molecules per each molecule respectively
Following are the answers:
The two reactants that enter the mitochondrion are pyruvate, the end product of glycolysis, and oxygen.In the mitochondria, pyruvate and oxygen undergo a series of reactions called cellular respiration, which produces energy in the form of ATP. This process is more efficient than glycolysis, which only produces a small amount of ATP.A cell obtains energy through a variety of processes, including cellular respiration and fermentation.Fermentation occurs in a cell when there is a lack of oxygen, such as in anaerobic conditions.In general, cellular respiration is more efficient than fermentation in producing ATP, but fermentation is a useful process for cells to produce ATP when oxygen is not available.What is mitochondria?Mitochondria are organelles found in the cells of most eukaryotic organisms, including plants, animals, and fungi. They are often referred to as the "powerhouses" of the cell because they are responsible for producing the majority of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy.
Mitochondria are membrane-bound structures that contain their own genetic material, separate from the cell's nucleus, and are responsible for their own replication. They have unique characteristics that allow them to produce energy through the process of cellular respiration, a series of reactions that convert the energy from food molecules, such as glucose, into ATP. This process is one of the most important biological processes in living organisms, as it allows cells to perform their functions and sustain life.
