What is the difference between small, controlled lab experiments versus an ecosystem-scale experiment?
Answers
Answer: the number of variables
Explanation:
The difference between small, controlled lab experiments versus an ecosystem-scale experiment is the number of variables.
What is an experiment?A technique used in science to create a discovery, test a hypothesis or prove a known fact.
Lab experiments are done in the lab with a limited amount of variables as there is limited space available.
The ecosystem-scale experiment is performed on large scale and with many variables.
Thus, the difference is the number of variables.

why do you think are the reasons why only few seeds germinate
Answers
Answer:
The germination of a seed can eventually be affected by temperature, humidity and oxygen. Generally, the seeds remain viable longer at low temperatures, a humidity range of 3% to 20% and an environment with low partial pressure of oxygen. If some of these factors are not met, the seed can age or eventually germinate.
Explanation:
Seeds are the main reproductive organ of the vast majority of higher terrestrial and aquatic plants. They play a key role in the renewal, persistence and dispersal of plant populations, the regeneration of forests and ecological succession. In nature the seed is a staple food source for many animals. Seed germination often takes place on the surface of the soil, so the balance between the gain of soil moisture and its loss by transpiration to the atmosphere determines when the seed becomes saturated with moisture and begins to germinate.
The reasons why only few seeds germinate are as a result of some factors such as temperature, availability of water, depth of plant, presence of plant hormone (Gibberellin) in the seed. etc
Seed Germination is a process after seed dormancy where seeds sprout and develop into a new young plant. The reason why some seeds germinate and others do not are some of the following:
Temperature: For the germination of seed to occurs, seed needs to undergo a moderate amount of soil temperature. The cotyledon of the seedling gets destroyed when the seeds are being exposed to an extreme soil temperature. This is why most seed doesn't thrive in the deserts.
Availability of water: The soil in which seeds need to be planted must be moist and contain have a moderate amount of water holding capacity for the survival of the seed plant. The moderate amount of water holding capacity can be seen in humus soil.
Presence of plant hormone: The presence of Gibberellin in seeds helps the activation of the cotyledon to begin the germination process after the seed has absorbed water from the soil. In seeds where the enzymes are absent, such seeds do not germinate.

Answer:
chlorophyll
Explanation:

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.
Before the widespread use of antibiotics, there were very low levels of antibacterial resistance. As antibiotic use has grown, so has the number of antibiotic resistant bacteria. WHY do you think this has occurred?
Answers
Answer:
This is because antibiotic resistance can be caused by bacteria getting the ability to be unaffected by the antibiotics Also, people not taking their medication for the entire duration exposes the bacteria to the antibiotic and makes it stronger. Also, when people overuse antibiotics and mutations occur, the bacteria becomes antibiotic resistant.

1. How does a cell obtain energy?
2. Under what conditions does fermentation occur in a cell?
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.
