The correct answer is foot.
Mollusks have more diverse forms in comparison to any other animal phylum. They comprise, the slugs, snails, and other gastropods; squids and other cephalopods; clams and other bivalves; and other lesser known but identically different subgroups.
The cephalopods like octopuses and squids possess the head, which is prominent and the foot that has been amended into tentacles. The cephalopods have an absent or diminished shell and exhibit the most advanced nervous system of the invertebrates.
So given the suggested food chain of algae-snail-sunfish-heron we can conclude that this food chain is heavily dependent on the process of photosynthesis.
The algae is the only of the organism that are directly dependent of the photosynthesis for their survival, while the snail, sunfish, and heron, and indirectly dependent on it.
Since we are talking about a food chain, in essence it means that all organism are connected through one another. So the algae perform photosynthesis for its own survival, the snail is using the algae is a food source, the snail is later eaten by the sunfish, and the sunfish goes on the menu of the heron.
If the algae, by some scenario, are not able to perform photosynthesis, than they will die off, and if they die off, than the snail will die off because of lack of food, if the snail dies off, along with it dies off the sunfish because of lack of food, and if the sunfish is out of the scene, the heron goes as well.
So we can conclude that the process of photosynthesis is of crucial importance for the survival of all four species, be it directly or indirectly.
The knowledge gained will lead to further experimentation that could potentially result in a new use for the drug.
Our perception of the brightness of a color is affected mainly by: the amplitude of light waves.
Night and peripheral vision depend mainly on rods, while daylight and acute vision depend mainly on cones.
The amount of light entering the eye is regulated by changes in the size of the pupil.
If you project a red, a green, and a blue light into space, the point at which the three lights cross will lead to the perception of white light.
eric has been wearing red welding goggles for the past 30 minutes. Based on the opponent-process theory of color vision, when Eric takes off the red goggles, he should expect that objects will temporarily appear to be green.
Answer:
A biologist studying ponds in Alaska wants to determine if the temperature of a pond affects the length of the fish in that pond. He traps and measures fish in each pond, gathering the following data:
Choose a way to represent this data using either a bar graph or a scatter plot. Then write a summary of the data to answer the question as to whether temperature is related to the size of fish.
Explanation:
