What is simulation in research ?Simulation is the re-enactment of real-world situation for different reason as it cannot be done in real due to several reasons.
This is completely conducted in a controlled environment which also the modification or addition of variable factor if needed.
The primary aim of this technique is to teach people with the appropriate steps to take in the event.
It is mostly used in cardiopulmonary resuscitation (CPR), science experiments, movies, sports, and video games.
It is used to identify what type of situation needs to be recreated and assess will be feasible, the goal for doing simulation should be decided, the device, model or parts need to be executed during simulation.

Answer:
I believe that the answer would be: Evolution of the fruit fly over time (A)
Explanation:
As we can see, the fruit fly shown is the only fruit fly we are observing. Therefore, we need to determine how it has different cells among other cells. This is where evolution would come into the picture. The reason this fruit fly has different cell structures and functions is because, over time, their bodies and makeup have changed, leaving behind these "older" cells that are now dominated by the newer ones. So, evolution is the reason why the fruit fly has different cell structures and functions.
Just like how us humans have wisdom teeth in our mouths that are not necessary because our mouths have evolved to be smaller; there isn't enough room for them to grow, in some cases.

What can a scientist
learn by observing the
behaviors of a particular
animal?
Answer: Sense food, Predators
Explanation: They can observe the animals odor and they can also observe the animals predators.
Scientists are inspired to the survey of animal behavior for a variety of reasons, and the ground is pretty varied, ranging from feeding behavior and habitat selection research to mating behavior and social organizations.
What is animal behavior?Animal behavior encompasses all of the ways in which animals interact with other organisms and their physical surroundings.
Behavior can also be defined as a change in an organism's activity in response to a stimulus, an external or internal cue, or a combination of cues.
Animal behavior connects the molecular and physiological aspects of biology to the ecological.
Behavior is the link between organisms and their surroundings, as well as between the nervous system and the ecosystem. One of the most important aspects of animal life is behavior.
Animal research helps scientists understand how living creatures, both human and animal, function.
Animal research allows us to get a close-up look at living organisms and how their physical, chemical, and functional life systems function.
Thus, this way, a scientist can learn many varied things regarding organisms by learning animal behavior.

How do eukaryotic cells carry out the processes they need to live?
Answer:
Unlike prokaryotes, eukaryotic cells compartmentalize various metabolic processes inside membrane-bound organelles. For example, the breakdown of certain food molecules to provide energy takes place in the mitochondrion, and photosynthesis takes place in a chloroplast.
Answer:Eukaryotic cells generally use aerobic respiration – requiring oxygen – to produce usable energy called ATP from glucose molecules. ... This type of respiration mostly takes place in specialized organelles called mitochondria. Prokaryotic cells, on the other hand, tend to use anaerobic respiration – not requiring oxygen.

1) What was the rationale behind introducing wolves to the Greater Yellowstone Ecosystem (GYE)?
Answer: was to increase the population of wolves
Explanation: The reasoning behind introducing these gray wolves (Canis Lupus) to the Greater Yellowstone Ecosystem was to increase the population of wolves there since they were once scattered because of people killing these animals off with the assumption that they were predators and were viewed as dangerous animals.
The rationale behind introducing wolves to the Greater Yellowstone Ecosystem is that it is considered a way of increasing the population of wolves.
What is an Ecosystem?An ecosystem may be defined as the place or area where members of different species live together and interact with one another for the purpose of food, space, and mating partner.
It may be thought that in the past time people were significantly killing wolves with the supposition that they belongs to the category of predators and were typically observed as dangerous animals. Now, if they were introduced again in this environment, the rationale behind this introduction is only for improving the population of wolves.
Therefore, the rationale behind introducing wolves to the Greater Yellowstone Ecosystem is that it is considered a way of increasing the population of wolves.

Chlorophyll is the green pigment needed for photosynthesis and precipitation is the water released into the atmosphere through stomata.
What is the role of chlorophyll?Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Chlorophyll molecules are specifically arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts.
Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and is used for the synthesis of food in all green plants. Produces NADPH and molecular oxygen (O2) by photolysis of water.
Chlorophyll absorbs the light energy required to convert carbon dioxide and water into glucose. It is found within chloroplasts in cells exposed to light. Chlorophyll is green - so absorbs the red and blue parts of the electromagnetic spectrum.

Two different types of flood hazard assessment methods were tested: (i) a ... elongation ratio and roughness index can be used to explain the flash flood types.
Answer:
Flooding is an overflowing of water onto land that is normally dry. Floods can happen during heavy rains, when ocean waves come on shore, when snow melts quickly, or when dams or levees break. Damaging flooding may happen with only a few inches of water, or it may cover a house to the rooftop. A flash flood is = A flood caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours. Flash floods are usually characterized by raging torrents after heavy rains that rip through river beds, urban streets, or mountain canyons sweeping everything before them.
