Which 2 body systems work together to transport oxygen to cells?

Answers

Answer 1

Answer: The respiratory system and the circulatory system.
The respiratory is involved when you breath and intake oxygen into your body. It goes into your lungs and into alveoli located in your lungs. When the oxygen is there it gets absorbed into the bloodstream and the circulatory system transports it around your body to deliver the oxygen.

b.proteins.
c.salt.
d.water.

Answers

Answer:

b. proteins.

Explanation:

Ribosomes are cell organelles present in the cytoplasm of prokaryotic and eukaryotic cells. In prokaryotic cell ribosome is 70S (S is the Svedberg unit) type and in eukaryotes it 80S type. Besides in cytoplasm of eukaryotic cells, mitochondrial matrix and stroma of the chloroplasts have their own ribosomes similar to prokaryotic ribosomes. Ribosomes in association with endoplasmic reticulum provide platform for the synthesis of polypeptide (protein). The transcribed mRNA is translated into primary protein on ribosomes. Lipids are synthesised by smooth endoplasmic reticulum.

Which organisms utilize a one-way air flow through their lungs to maximize airflow efficiency and oxygen consumption?

Answers

The answer is birds.

Birds utilize a one-way airflow through their lungs to maximize airflow efficiency and oxygen consumption. Although they inhale and exhale through one trachea, air flows in one direction through birds lungs. This is enabled thanks to air sacks. When birds inhale, air travels through the trachea, which further divides into two bronchi. The part of the air enters the lungs, and the other part remains in posterior air sacks. After the first exhalation, the fresh air from the posterior air sacks enters the lung and displace the spent air which is moved to the trachea. In case there is fresh air in the trachea, spent air is moved to anterior air sacks and after following exhale, it flows out from the trachea.
