Answer:
0.900 Jg^-1℃^-1
Explanation:
Given that;
H = mcθ
H = heat added
m = mass of aluminium
c = specific heat of aluminum
θ = increase in temperature
Making c the subject of the formula;
c = H/mθ
c = 207 J/28.4 g * 8.1oC
c = 0.900 Jg^-1℃^-1
The answer is 3. Adaptations help the organism survive in their environment
Answer:
Explanation:
A circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours.It can refer to any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These 24-hour rhythms are driven by a circadian clock, and they have been widely observed in plants, animals, fungi, and cyanobacteria.
Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To find out how it works, imagine a population of beetles: There is variation in traits.
I would not take my word on this but i do think that, that is TRUE.
