<h3>Duplication requires the separation of complementary DNA strands to allow for DNA replication. </h3>
Explanation:
Several interacting forces such as Vanderwaal's forces, hydrophobic interaction and hydrogen bonds stabilize the DNA double helix structure.The strands of DNA double helix are held together by the hydrogen bond between the corresponding nucleotide bases. The separation of complimentary strands occur during replication because breaking the hydrogen bonds are comparatively easier than breaking any other bond stabilizing the DNA double helix.
Quinine is used to treat malaria and its symptoms (B). It works by killing the organisms that cause malaria (Plasmodium falcipartum). Keep in mind its only used to treat malaria, but not to prevent it.
Answer:
An absorption spectrum illustrates the spectrum of light or electromagnetic radiation absorbed by the plant. This relies upon the molecular and cellular build-up of the plant. An action spectrum illustrates the spectrum of electromagnetic radiation most efficient for photosynthesis.
The action spectrum of photosynthesis monitors the absorption spectrum of chlorophyll. The absorption spectrum suggests that how much of each wavelength chlorophyll will captivate, while the action potential can indicate to us about the wavelengths that are most operative for photosynthesis.
In case of Jamaal's task, the memory system which is most important is WORKING MEMORY SYSTEM or SHORT-TERM MEMORY SYSTEM.
In case of humans, there are 3 typed of memories:
1. Sensory memory
2. Short-term memory (Working memory)
3. Long-term memory (Life time memory)
Since in the above question, Jamaal needs to memorize the phone numbers for a short period of time, it is an example of short-term memory.
