Answer:
The answer to this question is given below in this explanation section.
Explanation:
"advantages of interconnecting air sacs for birds"
The air sacs permit a unidirectional flow of air through the lungs.Unidirectional flow means that air moving through birds lungs is largely fresh air and has a higher oxygen content.In contrast air flow is bidirectional in mammals moving back and forth into and out of the lungs.As a result air coming into a mammals lung is mixed with old air has less oxygen. so in bird lungs,more oxygen is available to diffuse into the blood(avian respiratory system).
- The air sacs are thin membrane structures connected to the primary or secondary bronchi via ostia and they comprise most of the volume of the respiratory system.
- Air sacs are poorly vascularized by the systemic circulation and do not directly participate in significant gas exchange but act as a bellows to ventilate the lungs.In most species,there are nine air sacs which can be considered in cranial and caudal functional groups.
- The cranial group consists of the paired cervical air sacs,the unpaired clavicular air sacs and the paired cranial thoracic air sacs.
Answer: They use enzymes.
Explanation:
Cells employ enzymes to drive and speed up their chemical reactions without being used up themselves. They are the only macromolecular biological catalysts that can start a reaction using the smallest available heat energy, thus overcoming the issue of needing high activation energy. Enzymes work by converting specific substrates to required product by binding them to their active site.
Because of translation, the RNA strands is able to become a protein, so RNA makes the protein
Answer: the camel
Explanation:
because of its adaptation to the desert
The metabolic pathway based on products produced is ;
- 4 ATP and 4 Hydrogen ions
The product 4 ATP + 4 Hydrogen ions is formed through a metabolic pathway ( glycolysis ) whereby glucose is oxidized to obtain ATP.
A metabolic pathway is series/chain of chemical reactions feeding each other and occurring mostly in living organisms. A common example of a metabolic pathway is the breaking down of glucose in human body ( glycolysis ).
Hence we can conclude that the metabolic pathway based on products produced is 4 ATP + 4 Hydrogen ions.
