Answer 1
Answer: A person who has allergies has them because his or her body over reacts to a material that would otherwise be ignored. It is an overreaction of the immune system triggering a immune attack response that is unneeded. For instance, A person with a peanut allergy has a body whose immune system flags the peanut protein as an intruder and attacks it. It produces antibodies and causes growning reactions that can be life threatening and cause anaphylaxis.

Which aquatic biome forms where freshwater streams or rivers merge with the ocean? form where freshwater streams or rivers merge with the ocean.

Answers

Estuaries, aquatic biome, forms where freshwater streams or rivers merge with the ocean.

What is estuaries?

Estuaries are a transitionalzone between river environments and ocean environments.

They are impacted by both riverine and marine factors, including flows of freshwater and sediment as well as marine factors like tides, waves, and the inflow of salt water.

In addition to lagoons, river mouths, and tidal creeks, this wide definition encompasses them.

An estuary is a dynamic ecosystem that connects to the open sea and allows seawater to enter in accordance with the tide cycle. The fresh water flowing from rivers and streams dilutes the seawater that enters the estuary.

Therefore, where freshwater rivers meet saltwater seas is where estuary biomes typically occur.

4. dolphins

Thank you for posting your question here at brainly. I hope the answer will help you. 

Answer:

The correct answer is - humpback whales →sea turtles→humans→dolphins.

Explanation:

The hearing of sound is measured in hertz which is the unit of the sound that depends on the different frequencies of individual produce. The range of hearing sound is different in different animals.

Humpback whales produce sound between 30 to 8000 Hz however whales sense the vibration made by their song or sound by another whale. Sea turtles are able to hear in between the 20 to 1000 Hz whereas humans are able to hear 20 to 20000 Hz.

The highest hearing range of the sound is by dolphins from giving options as they are able to hear sound between 40 to 130000.

Thus, the correct answer is- humpback whales →sea turtles→humans→dolphins.
