all plants give out oxygen during day and carbon dioxide during night. Do you agree with this statement. Give reason
Citrus2011 [14]

This statement is incomplete.

"All plants give out oxygen during day and carbon dioxide during night"

Explanation :

Photosynthesis occurs only during day time.

During this time oxygen is produced . Some oxygen is used for respiration and rest of oxygen is diffused out into air.

Carbon dioxide produced during day time by respiration is used in photosynthesis.

But at night time, no photosynthesis occurs  and hence no oxygen is produced oxygen from air diffuses into leaves to carry out respiration and carbon dioxide produced by respiration diffuses out into air.

Hence Respiration occurs day and night .. Hence Carbon dioxide  is emitted  all the time....

leonid [27]

Answer:

T and B cells.

Explanation:

Adaptive immunity is the kind of immunity that you acquire after exposure to an antigen (pathogen or vaccine), it involves memory in order to facilitate a quick response if there's a reinfection with the same pathogen.<em> T cells are responsible for the cell-mediated response while the B cells are responsible for the humoral response.</em> Both of these cells are specific to the pathogen's structure, therefore they can kill it directly.

I hope you find this information useful and interesting! Good luck!
