The suns inner core is hottest part of sun

The core is the part of the star that generates all the heat, therefore the suns inner core is hottest part of sun

The sun inner core is the hottest part

Explanation:

the Sun's core can get as hot as 30 million degrees F. The photosphere, which is outside the core, is the coolest layer

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.
