The fish is a salt water organism. Its environment is hypertonic to its cell causing water to leaves its cell via osmosis The fish release small amount of dilute urine to maintain homeostasis. The correct option is B.
What is natural aquatic environment?Oceans, lakes, rivers, streams, estuaries, and wetlands all have aquatic ecosystems. Fish, plants, and bacteria are just a few examples of the living species that can only exist in aquatic settings. Because of their vulnerability, these ecosystems are quickly upset by pollutants.
What are the benefits of aquatic environments?Aquatic habitats serve a variety of important environmental roles. They replenish groundwater, cleanse water, reduce floods, increase and maintain streamflow, offer habitat for wildlife, and provide people with recreational opportunities.

For the following please tell me if they can or cannot cross the cell membrane without help? Why or why not.
Na+, Glucose, O2, Insulin, CO2, Fructose, K+,
Na+, K+, and insulin cannot cross the cell membrane without help whereas Glucose, oxygen, carbon dioxide and Fructose can diffuse.
What type of molecules can cross cell membranes without energy?Small nonpolar molecules like oxygen and carbondioxide are soluble in the lipid bilayer and so they can easily cross cell membranes. Small molecules such as water can also diffuse through cell membranes but larger molecules such as glucose, cannot diffuse through the cell membranes. Nonpolar molecules can pass through the cell membrane easily. Some larger nonpolar molecules like steroid hormones can also pass through the cell membrane easily. Moving through the cell membrane without the need for assisting proteins is called passive diffusion.
So we can conclude that Glucose, oxygen, carbondioxide and Fructose can cross the cell membrane without energy.

layers of sand and other sediments that become sedimentary rock can contain
The particles which forms sedimentary rocks usually contains calcite or quartz.
Understanding the composition of sedimentary rocks.The composition of a substance are what the substance is made up of. Within the context of this question, before the sedimentary rocks are formed, the layers of the its constituents which when subjected to high temperature and forms sedimentary rock contains a substance known as quartz. This quartz is also known as the siliciclastic rocks.
However, the layers or substance or particles which forms sedimentary rocks also contains the carbonate rocks also known as calcite.
There are three major types of rocks:
Igneous rock: It is formed by the cooling of molten rock, either below the surface (intrusive) or on the surface (extrusive).Metamorphic rock: It consists of pre-existing rock mass in which new minerals are formed at higher temperatures and greater pressures.Sedimentary rocks: It is formed by the deposition of either the weathered remains of other rocks, the results of biological activity, or precipitation from solution.So therefore, the constituents which makes up sedimentary rocks contains calcite and quartz.

which organism has a nerve net that allows it to a stimulus in a coordinated way
The organism that has a nerve net that allows it to a stimulus in a coordinated way is called option C: Hydra.
What kind of animal is Hydra?The majority of cnidarians, including those in the genus Hydra, contain what is known as a neural net, which is an organism-wide network of distinct and individual nerve cells and fibers.
Hydra species have two nets, one attached to the gastrodermis and the other situated between the epidermis and the muscles.
Invertebrate freshwater animals of the genus Hydra belong to the class Hydrozoa. Such an organism has a thin, transparent tube for a body that can grow up to 30 millimeters long but can also contract significantly.
Therefore Hydra have nerve net that is used respond to the touch of physical contact as well as other functions.
