AI Thread Summary
DNA bases pair due to complementary bonding, where adenine pairs with thymine and cytosine pairs with guanine, ensuring accurate replication. A defining feature shared by living organisms and viruses is the presence of genetic material, either DNA or RNA. However, a key feature exclusive to living organisms is the ability to reproduce independently, which viruses cannot do without a host. Engaging with textbooks and research can clarify these concepts and facilitate understanding. Exploring these foundational biological principles enhances comprehension of life’s characteristics.

1. Why do DNA bases pair the way they do?

2. What is one defining feature of a living organism that is also found in a virus?

3. What is one feature shared by all living organisms but not by viruses?

You have to attempt a solution - there is no point in us just telling you the answer.
 
These seem like things you could glean from your textbook. Try looking up the structure and definitions of these things first and revisiting the questions. You'll find they seem much easier. :)
 
Thread 'Confusion regarding a chemical kinetics problem'
TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
