What do cellular respiration and fermentation have in common? They both occur in the mitochondria, they both Harvest energy from sugars, they both require oxygen to occur, they both end up with pyruvic acid.
Answer:
Fermentation and cellular respiration are alike in that they both begin with a series or reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes ATP is produced for the cell to use.
Hope it helps.
Answer:
They both harvest energy from sugars.
Explanation:
Cellular respiration and fermentation are reactions of the energy metabolism of organisms, which aims to obtain energy for metabolic reactions from the breakdown of glucose (sugar) in ATP. ATP keeps in its phosphate bonds energy that will be used in metabolism. This nucleotide is the energy currency of the cell.

2. Scientists often work together with other scientists. If you were working in a scientific laboratory, how could you help people in your laboratory work together in a way that is effective, and help make sure that people got fair credit for their work? What is needed for people to work together in an effective way? (10 points) APEX
Hi
I think a very important thing while working in a scientific laboratory is to have cooperation along with a sense of individual responsibility. There are many times when you are not expert in one scientific technique but your senior or fellow worker is because of his/her prior experience. At that point, the people of laboratory should cooperate with each other in giving some tips regarding performing a specific technique and getting the results with minimum time wastage. This does not mean that you take help from some one without giving them credit.
There should be a lab attendant in every lab who should be consulted for every problem so that he can assign some relevant worker to help you in the work. After you get the help, the attendant should confirm from both persons and keep a log about it which they should appreciate and give a fair credit about inquiries of higher authorities like supervisors.
Another important factor that is important for people is to have a sense of respect for each other. This is important to listen to others without just thinking about our own perspective and our own understanding. This also enables to understand a point from larger view and can help to bring a point in mind which we otherwise might skip.
This simulation shows only the changes in energy that cause the motion of the skateboarder what energy transformations are going on with in the skateboarders body during this process. Please help ASAP
Answer:
Plato Answer
Explanation:
Some of the skateboarder’s stored chemical energy is being used to fuel muscle movement. This movement would also involve a release of thermal energy by the skateboarder.
Answer:
Potential energy will transform into kinetic energy. Potential energy will become kinetic energy and both energies can release thermal energy.
Explanation:
Let' suppose a physics simulation similar to the attached file.
We have a skateboarder moving on the surface.
The skateboarder varies his position. The highest point of the trajectory will have the highest potential energy and the lowest kinetic energy.The lowest point of the trajectory will have the lowest potential energy, all the potential energy will become kinetic energy. So, the lowest point of the trajectory will have the highest kinetic energy value.
As a consequence of friction force, part of both energies could convert in thermal energy.
Finally, we can conclude that Potential energy will transform into kinetic energy. Potential energy will become kinetic energy and both energies can release thermal energy.

How are photosynthesis and cellular respiration related?
O
O
O
A. They are both performed by animals.
B. They are both performed by plants.
c. They both produce glucose molecules.
D. They both require energy from the sun.
O
Answer:
B
Explanation:
Photosynthesis requires sunlight and produces glucose but animals do not carry out photosynthesis and animal cells do not have the chloroplasts to absorb sunlight. Therefore A is false as is C and D as respiration uses glucose and does not produce it. And respiration transfers energy to cells that needs it therefore sunlight energy is not required.
Hope this helps.
Photosynthesis and cellular respiration are interrelated processes where photosynthesis creates glucose and oxygen, which are then used in cellular respiration to produce energy, carbon dioxide, and water. They function as opposite halves of a cycle that facilitates the energy flow within ecosystems and helps regulate the levels of carbon dioxide and oxygen in the atmosphere.
Explanation:Photosynthesis and cellular respiration are related in that they are essentially opposite processes that work together to facilitate the flow of energy through living organisms. Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy from the sun into chemical energy stored in glucose, releasing oxygen as a byproduct. Cellular respiration is a process that all living organisms perform, in which oxygen and glucose, produced by photosynthesis, are used to generate ATP, the energy currency of the cell, with carbon dioxide and water being released as byproducts.
To sum up, while photosynthesis converts carbon dioxide and water into glucose and oxygen using the sun's energy, cellular respiration converts glucose and oxygen back into carbon dioxide and water while releasing usable energy stored in ATP. This cyclical relationship is critical for the energy flow and the constant recycling of carbon dioxide and oxygen in the Earth's atmosphere. It forms part of the larger carbon and energy cycle of our planet.
what are the physiological reactions to stress in the alarm stage
Answer:
Physiological reactions to stress in the alarm stage include: increased heart rate and blood pressure, dilated pupils, rapid and shallow breath, and increased cortisol levels.
Explanation:
Hans Seyle, a medical doctor proposed a model called the General Adaptation Syndrome (GAS) to explain the effects and stages of coping with the stress. The GAS model has three stages, known as:
1. Alarm stage
2. Resistance stage
3. Exhaustion stage
The alarm stage is the first stage of responding to stress. During this stage, the fight-or-flight response is activated when an individual is experiencing stress. This stage involves the following physiological reactions:
1. Increased heart rate
2. Increased blood pressure
3. Dilated pupils
4. Rapid and shallow breath
5. Increased cortisol levels
HELP!! Decomposers are important to the biogeochemical cycle because they break down organic matter and make the nutrients available to other organisms. What is the process of breaking down organic nitrogen to ammonia known as?
Answer:
Ammonification
Explanation:
The ammonification is part of the nitrogen cycle. This process occurs when the plants and animals die. The dead plants and animals start to decompose because of the organisms like the fungi and bacteria that manage to decompose them. As they are decomposed, the nitrogen is converted into ammonium by the decomposers. The ammonium is returned into the soil, thus becoming available for the living organisms that can extract it from it, and in that manner continuing the nitrogen cycle.

Conifer needles have
A. a thick cuticle.
B. sunken stomates.
C. a reduced surface area.
D. all of the above
Answer:
D. all of the above
Explanation:
Conifers are a group of trees which belong to the class of gymnosperms. They are cone bearing plants which means that the seeds are formed in a beautiful cone shaped structure. Some of the trees belonging to this class are shrubs while majority of them are trees.
Some significant features of the leaves of conifers are those mentioned in the question. They have a very heavy cuticle in the region of epidermis for protection of leaves. The stomata are deeply sunken in leaves and are present in the form of layers. Moreover, the leaves are very thin like those of grasses and therefore they have very less surface area as compared to the leaves of other plants like roses.
Please see the conifer leaves in attached picture for better understanding.

How do paleontologist learn about evolution ?
Paleontologists study fossils to learn about evolution by analyzing their structure, age, and distribution. Fossil records help determine relationships between species and the influence of events like mass extinctions. Various dating techniques are used to determine the age of fossils and the sequence of evolutionary changes.
Explanation:**Paleontologists** study fossils to learn about evolution. They analyze the structure, age, and distribution of fossils to understand how species have changed over time. By examining fossilized bones, teeth, and other preserved remains, paleontologists can trace the evolutionary history of different organisms.
For example, the fossil record shows a progression of horse evolution from small, multi-toed ancestors to the larger, single-toed horses we see today. Patterns in the fossil record also help paleontologists determine the relationships between different animal groups, and how major events like mass extinctions have influenced evolutionary pathways.
Furthermore, paleontologists use various dating techniques, such as radiometric dating and relative dating, to determine the age of fossils and the sequence of evolutionary changes. By combining different lines of evidence, including fossil records, genetics, and anatomical comparisons, paleontologists can gain a comprehensive understanding of how evolution has occurred.
