Final answer:

Filter feeders and fluid feeders both rely on filtration to consume nutrients, but they do so in distinct ways. Filter feeders sift their nutrients from water, whereas fluid feeders consume liquid food.

Explanation:

The main similarity between filter feeders and fluid feeders is that they both rely on the process of filtration to consume nutrients. Filter feeders, such as whales and clams, sift their food from the water by filtering it through their specialized bodily structures. On the other hand, fluid feeders like mosquitoes and butterflies, consume liquid food, usually by sucking it up, but also use a form of filtration to separate food particles from the liquid.

Both types of feeders obtain their nutrients indirectly and have adapted to their unique feeding methods through evolution. They are both part of the broader category of indirect feeders in the animal kingdom.

Glycogen provides long-term energy storage.

Glycogen is an example of a carbohydrate which is a polysaccharide that acts as a long-term energy storage compound in animals.

Further Explanation

• Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
• Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.  

Energy source in animals

• Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
• These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
• When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
• Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.

Energy source in plants

• In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.  

Why other Choices are incorrect:

Glucagon  

• Glucagon is the hormone that increases the blood glucose level to avoid it from dropping below optimum level.
• The hormone acts on the liver to stimulate the breakdown of glycogen to glucose, a process called glycogenolysis, and the glucose is released to the blood stream.

Glucose

• Glucose is a simple carbohydrate classified as monosaccharides. It acts as the short term source of energy in both plants and animals.
• It is readily broken down during the process of cellular respiration to yield energy in the form of ATP, which is then used to drive cellular processes.

Cellulose

• Cellulose is an example of a complex carbohydrates known as polysaccharides.
• It is found in plants cells lining the cell wall of all plant cells which is one of the key distinguishing feature between plant cells and animal cells.

Glycogen serves as a long-term energy storage molecule in animals, including humans. Therefore option A is correct.

It is a complex carbohydrate made up of glucose units linked together in a branched structure. When dietary glucose levels are high, excess glucose is converted into glycogen and stored primarily in the liver and muscles.

This stored glycogen can be broken down into glucose when energy is needed during periods of fasting, exercise, or other metabolic demands.

Glucose, on the other hand, is a simple sugar that serves as an immediate energy source, while glucagon is a hormone involved in regulating blood glucose levels. Cellulose, a structural polysaccharide, is not used for energy storage in animals.

Question options:

A new scientific law would be established and proven by the findings. A new scientific theory would be established and proven by the findings. A current scientific law would be revised based on the new findings. A current scientific theory would be revised based on the new findings.

Answer:

A current scientific theory would be revised based on the new findings.

Explanation:

If new findings came about and challenged the current theory of natural selection so that Darwin's theory didn't look like it was true at all, the initial theory(darwin's theory of natural selection) would not be entirely discarded but revised according to these new findings and then form a sort of backbone to this new theory which would be based on findings of many independent researchers and not just one. Example: how some of Sigmund Freud's theories or Aristotle's may not be entirely valid today but still works as a fundamental for understanding other theories.
