Which Type Of Sentence Is This? Humans Breathe In Before They Dive Underwater, But Harbor Seals Exhale And Then Use Stored Oxygen For Breathing. (2023)

FAQs

Do humans breathe in before they dive underwater but harbor seals exhale and then use stored oxygen for breathing? ›

All mammals breathe in basically the same way, but some store oxygen more efficiently. Seals store oxygen in their blood and muscles, not necessarily in their lungs. They breathe out before they dive -- not holding their breath like humans do -- and rely on stored oxygen reserves to sustain them underwater.

A simple sentence uses just one clause, whereas a compound sentence uses two or more independent clauses. A complex sentence features at least a single independent clause as well as at least one dependent clause.

Simple, Compound and Complex Sentences

A simple sentence is a sentence that consists of just one independent clause. A complex sentence is a sentence that contains an independent clause and one or more dependent clauses. A compound-complex sentence combines the two.

They take a deep breath when they're on the surface of water and hold their breath for a very long time when they dive into the water. Human beings cannot hold that much air in their lungs so we only stay under water for short periods before we have to come back out to breathe air.

Oxygen from our gills would keep us from blacking out as we moved deeper, but below 200 meters or so we'd reach the bathyal zone, where it's dark and the water is 59 degrees Fahrenheit or colder [source: Britannica]. Living underwater in the shallows without some pressurized airspace wouldn't be an option either.

An example of a compound sentence is, 'This house is too expensive, and that house is too small. ' This sentence is a compound sentence because it has two independent clauses, 'This house is too expensive' and 'that house is too small' separated by a comma and the conjunction 'and.

Simple Sentences - He studied hard. He wanted to go to medical school. He suffered from arthritis. Complex Sentence - He studied hard because he wanted to go to medical school as he suffered from arthritis.

A complex sentence is made up of a main clause and a subordinate clause connected to each other with a subordinating conjunction. Subordinating conjunctions are common in academic writing, and they are extremely useful for indicating sophisticated connections between ideas.

A complex sentence is a sentence that contains an independent clause and one or more dependent clauses. An independent clause can stand alone as a sentence, but a dependent clause even though it has a subject and a verb cannot stand alone.

What are 5 examples of compound sentences? ›

There are four types of sentences: simple, compound, complex, and compound-complex. Each sentence is defined by the use of independent and dependent clauses, conjunctions, and subordinators. Simple sentences: A simple sentence is an independent clause with no conjunction or dependent clause.

A compound sentence has two (or more) independent clauses. A complex sentence has one independent clause and one or more dependent clauses. A compound-complex sentence has two (or more) independent clauses and one (or more) dependent clauses.

Unlike humans, harbor seals breathe out before diving. They use oxygen already in their blood and muscles while under water, and their heartbeat slows from about 100 beats per minute to 10. In one breath a seal can exchange 90% of the air in its lungs. Humans can only change 20% of our air per breath.

Prior to diving, phocid (true) seals generally exhale, a behaviour thought to assist with the prevention of decompression sickness. Otariid seals (fur seals and sea lions) have a greater reliance on their lung oxygen stores, and inhale prior to diving.

Harbor seals have a grater volume of blood than other land mammals their size. More blood means more oxygen storage. In addition to this, the muscles contain high levels of a protein called myoglobin. Myoglobin holds onto the oxygen molecules until they are needed by the muscles.
