The base pairing rules<span> for </span>DNA<span> are governed by the complementary </span>base pairs<span>: adenine (A) with thymine (T) in an A-T </span>pairing<span> and cytosine (C) with guanine (G) in a C-G </span>pairing<span>. Conversely, thymine only binds with adenine in a T-A </span>pairing<span> and guanine only binds with cytosine in a G-C </span>pairing<span>.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
Answer: Mutualism
Explanation: The definition of mutualism states " interaction between two or more species where each species has a benefit". The bird is getting food from the insects and the horse is getting the insects removed. Both are benefited.
D. Homeostasis- naturally selected function
The correct answer is: 2)The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions
The light-dependent reactions is one of the two successive phases that occur during photosynthesis (other is light-independent reactions). The light-dependent reactions use sunlight energy to make the energy storage molecule ATP and the reduced electron carrier NADPH. In the light-independent reactions (also called Calvin cycle), CO2 is absorbed and fixed in order to build three-carbon sugars (glyceraldehyde-3-phosphate) and this process is fueled by, ATP and NADPH from the light reactions.
