It would depend. 
The weather might be different form mine. I can give you the four main types of clouds there are to help you identify them.
Cirrus clouds are wispy, feather like clouds. They are higher than the other types of clouds.
Stratus clouds are low level clouds that are light gray. They might cause fog. 
Cumulus clouds are puffy, white clouds. 
Cumulonimbus could are very tall clouds that produce T-Storms. They are a very dark gray. 
There are other types of clouds, but these were the four I learned. 
 
        
                    
             
        
        
        
<span>The sequence of alternation of generation is; gametes->zygote->sporophyte->spores->gametophyte->gametes.
The attached diagram shows clearly this looped cycle. Alternation of generation
occurs in a more advanced land plant that
has distinct
haploid and diploid phases in their life
cycle. The diploid phase usually involves
the sporophyte while the haploid phase involves the gametophyte</span>
        
             
        
        
        
Endocrine signaling is hormone based signaling that travels through the blood stream. Many of the sensors and integrating sensors of the endocrine system are located in the brain. The brain barrier contributes to endocrine signalling, such that the brain barrier does not factor in with endocrine signalling. The answer is A
