Which statement applies to transverse waves?

The waves have a trough.
Particles move great distances.
The waves have alternating compressions and expansions.
The energy is transferred parallel to the direction of the wave motion.

Answers

Answer:

A) The waves have trough

Explanation:

100% sure

The statement 'the waves have a trough' applies to transverse waves.

What are transverse waves?

Transverse waves are a type of wave in which their fluctuations need to be perpendicular to the wave.

Conversely, longitudinal waves are waves in which their oscillations have the same direction of the wave.

A wave can be defined as any type of disturbance capable of carrying energy but that does not involve motion.

In conclusion, the statement 'the waves have a trough' applies to transverse waves.

A sugar farm near the coast of Florida applies a nitrogen based fertilizer to their soil three times a year. When rain falls on these fields after it has been fertilized some of the fertilizer runs off into the ocean causing the nitrogen levels in the water to increase. The increase levels of nitrogen can lead to many ecological effects beginning with the rapid growth of algae. This process is known as eutrophication.

How can eutrophication affect other organisms in the water?

Group of answer choices

The algae provide food for fishes and other organisms, leading to decreased algae populations.

The oxygen in the water is used up as algae is decomposed, reducing the amount available to other organisms.

The water becomes better able to support aerobic organisms.

The extra nitrogen provides additional food for the other organisms, increasing their population.

Answers

Answer:

The algae provide food for fishes and other organisms, leading to decreased algae populations

Explanation:

Excessive nutrients lead to algal blooms and low-oxygen (hypoxic) waters that can kill fish and seagrass and reduce essential fish habitats. ... Eutrophication sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants.

A population of a certain kind of fish is introduced into a new habitat. These fish have variations in color from light to dark. Because of the lighting conditions and predators in this new habitat, light colored fish survive better near the surface and dark-colored fish survive better near the bottom. What change would likely result after many generations of these fish living in this environment

Answers

Answer:

There would be two populations of fish:

Light-colored fishes near the surface

Dark-colored fishes near the bottom.

Explanation:

After many generations, there would be two populations of fish: Light-colored fishes near the surface and Dark-colored fishes near the bottom as light-colored fish survive better near the surface and dark-colored fish survive better near the bottom due to the lighting conditions and predators in the new habitat.

The difference between biotic and abiotic factors is that abiotic means non-living and biotic means living, that is the first statement, as biotic factors refer to living organisms in an ecosystem like plants and abiotic factors include soil.

What is the difference between biotic and abiotic factors?

Biotic factors refer to the living organisms in an ecosystem, such as plants, animals, fungi, and microorganisms, and these organisms interact with each other in various ways, including through predation, competition, and mutualism, while abiotic factors refer to the non-living components of the environment, such as air, water, soil, sunlight, and temperature, which can have a significant impact on the distribution and behavior of biotic organisms within an ecosystem.

Hence, the difference between biotic and abiotic factors is that abiotic means non-living and biotic means living, which is the first statement.

A population of sea urchins in a kelp forest ecosystem is being over-fished. A team of students believe that a decline in the number of sea urchins will affect the organisms in the kelp forest ecosystem. The kelp forest food web below shows the relationships among the organisms in the kelp forest ecosystem.

Answers

Answer:

Explanation:

This response shows some understanding of the question. The ecological relationships among the otter, crab, and urchin are addressed in a very general manner (kelp crabs and sea urchins feed off of kelp, only to be eaten by the sea otter). In a further explanation, the student overstates the effect of a decrease in the populations of the organisms. (The sea urchin and crab won't get the food from the kelp and die off. The otter will starve and die off too.) The supporting details are minimally effective.

Compartmentalization and restricting enzymes to specific organelles or membranes
Secreting enzymes out of the cell
Limiting the availability of substrates
Changing the primary structure of enzymes

Answers

Answer:

compartmentalization and restricting enzymes to specific organelles or membranes

Cellular steroid gradients are produced by the compartmentalization of enzymes into various organelles of a cell, and this might impact how well the various steroid products are balanced. Thus, option A is correct.

What is Compartmentalization?

In biology, the biomembrane, or biological membrane, effectively compartmentalizes enzymes by allowing them to perform only certain functions within a limited area.

The enzymes may be located on the membrane surface or inside the defined compartments.

A percentage of the enzymes would likely not work or their ability to catalyze reactions would likely be insufficient if there was just one cellular compartment.

This is because enzymes catalyzing distinct reactions frequently have variable temperature and pH optimums.

Therefore, Compartmentalization and restricting enzymes to specific organelles or membranes.
