Acertain type of plant is damaged by cold weather. the amount of damage gets worse as the weather gets colder.

a) in a cold winter, the phylem cells are damaged. how is the role of phloem affected in this type of weather?

b) in extreme weather, the xylem cells are damaged as well. describe how the plant is affected if the xylem is unable to function correctly?

a) The phloem is accountable for conducting food from the leaves to the rest parts of the plant, thus, in the absence of phloem, the plant will die.  

b) Xylem tissue plays an essential role in the transportation of minerals and water from the roots to the leaves of the plant. It is this water, which is utilized in the process of photosynthesis and also plays a role in the process of transpirational pull. In case, due to the destruction of xylem tissues wilting of plants takes place as it loses turgidity and dies as water is not able to reach the leaves for the process of photosynthesis.  

fabric is silk wool ext. paper isnt

explanation:

u cant make fabric out of paper cause paper comes from wood while fabric comes from animals

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
