13-22 Aquaculturists (people who farm marine resources, typically in semi-enclosed areas off the coast) have development methods of growing various invertebrates as food sources, such as clams, mussels, and oysters. Other widely consumed species, such as squid, have never been successfully grown in controlled marine environments, and so they remain wild caught. Why

Answers

Answer: There are several problems associated with handling of the squid.

Explanation:

Squid is a deep sea creature which becomes enormously big in size and difficult in handling in artificial water body or aquaculture.

It consumes and requires huge amount of food in the pre-larval stages typically phytoplankton and it becomes difficult to provide such food to them.

The maintenance of temperature, and salinity for the squid in aquaculture is difficult.

The sticky arms of the squid adhere to the surface of tub or human handler making it difficult to handle and can be poisonous to humans too.

Because of reflection of light away from the marking

Explanation:

It is because the light from a vehicle falls on the road and its markings which then gets illuminated as light is reflected only in one direction.

But in case when the road is wet, light of vehicle reflects in different directions away from the markings on the road and hence they do not illuminate.

The reason why the given phenomenon about the effect of light and while driving is; Due to total internal reflection of light away from the marking.

What is reflection of light?

Reflection of light is simply defined as the phenomenon where light is sent back after being incident on a surface.

Now, in this question, the light from a vehicle falls on the road and its markings and then gets illuminated as light is reflected only in one direction.

However, when the road is wet, the headlight of vehicles tend to reflect away from the markings on the road in different directions which make them not to illuminate.

Thus, we conclude that reason why the given phenomenon about the effect of light and water on driving is due to total internal reflection of light away from the marking.

Which wave interaction is shown by the diagram? o absorption o diffraction o reflection o refraction ​

Answers

Answer:I agree

Explanation:

Diffraction wave interaction is shown by the diagram.

What do you mean by diffraction?

Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.

The most common example of diffraction occurs with water waves which bend around a fixed object. Light bends similarly around the edge of an object. The animation shows wave fronts passing through two small openings.

Diffraction results from the interference of an infinite number of waves emitted by a continuous distribution of source points. According to Huygens' principle every point on a wave front of light can be considered to be a secondary source of spherical wavelets.

Fish or mammals? Argumentation

Answers

the answer I would have to go with is mammals

While mammals are better suited for life on land due to several advantages, fish have several adaptations that make them suitable for life in water.

Write the argumentation between fish and mammals?

Both fish and mammals are diverse groups with their own specialized adaptations and traits, making direct comparisons between them challenging. Here are some arguments for and against each, though:

Fish:

Argument for: Fish have streamlined bodies that make swimming more effective and gills that allow them to extract oxygen from the water, making them well adapted to living in water.

Argument against: Fishes often have less complex and intellectual anatomy and behavior than mammals.

Mammals:

Arguments in favor of mammals: Mammals have a greater range of body size and form than fish and adaptations for movement, such as the ability to run, jump, or climb.

Arguments Against: Due to their low buoyancy and inefficient swimming bodies, mammals are less adapted to living in water than fish.

The ultimate determination of which is "better" - fish or mammals - depends on the context and standards being used. Both groups have evolved to occupy a wide variety of ecological regions, but each has its own distinct advantages and disadvantages.

Therefore, while mammals are better suited for life on land due to several advantages, fish have several adaptations that make them suitable for life in water.
