Lichens are among the slowest-growing organisms, but their tolerance of environmental extremes enables them to colonize habitats

where few other macroscopic organisms can grow. They grow where neither the fungal partner (mycobiont) or the photosynthetic partner (photobiont) could survive alone, because they benefit from their unique symbiotic association. What mutualistic behaviors aid in the survival of both organisms?
A) The photobiont processes and provides nitrogen and carbon products to the mycobiont.
B) The photobionts are protected and able to grow in conditions in which they could not grow alone and in return release glucose in some form to the mycobiont.
C) The photobionts absorb mineral nutrients from the underlying surface or from minute traces of atmospheric contaminants while the mycobionts synthesize organic nutrients from carbon dioxide.
D) The photobionts produce ammonium and organic sodium compounds from N2 gas by sodium fixation; that in turn, aids the mycobionts in producing enzymes to decompose the substrate on which they live.

Answer:

The correct option is B.

Explanation:

Lichens  is regarded as a mutual relationship between a mycobiont and photobiont, the relationship is targeted at enhancing their survival in extreme environments. The mycobiont is a fungal while the photobiont is usually a green alga or a mycobacterium. Each of the organism has their specific tasks; the mycobiont provides suitable habitat for the photobiont while the photobiont provide energy for the whole system.

Answer:

The photobionts are protected and able to grow in conditions in which they could not grow alone and in return release glucose in some form to the mycobiont

Explanation:

The mycobionts help retain moisture for the algae. The algae undergo photosynthesis to produce-carbon based compounds, such as glucose, which is shared with the fungus.

Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which _____. see concept 44.2 (page 980)
Bas_tet [7]
Forms solid that are relatively insoluble and nontoxic

Uric acid is  product of the metabolic breakdown of the purine nucleotides. It is considered as a normal component of urine. In birds and reptiles the evolved the ability to convert toxic ammonia into uric acid or guanine rather than urea. These organisms are called as uricothelic organism because they have the ability to convert toxic ammnonia to uric acid instead of urea. Uric acid is less toxic than ammonia.
