In a heat wave in June 2017, temperatures in some southwestern U. S. states reached 49⁰C (120⁰F). To help cope with these high temperatures, some residents wrapped their outside metal door handles in cloth. How did this help the situation?

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

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.

you know they are heterozygous for a trait because they have it as jj or jj.

your answer is going to be physical weathering
