Answer:
The correct answer is- activation synthesis theory
Explanation:
The activation-synthesis theory tells us about the role of neuron in dream production during sleep. It was first proposed in 1977 by Allan Hobson and Robert McCarley which was psychiatrists at Harvard University.
This theory says that in REM sleep some neurons in the lower brains for example in the brain stem randomly activates due to change in neural signals and dream occurs when the cerebral cortex tries to interpret the meaning of these neuron signal changes.
So the correct answer to this question is- activation-synthesis theory.
Answer:
D) A = T; G = C
Explanation:
Chargaff's rules state that "DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine".
This pattern is noticed in the DNA strands.
Answer:

Answer:difference:
1)mango root system
Mango is having a well-defined Tap root system which can extend up to 20 feet (6 meters ). Taproots are the roots consists of one thick, cylindrical main root, known as the primary root, from which further branches of roots arises known as the secondary and the tertiary roots.
2)maize root system
Maize forms a complex root system comprising embryonic and post‐embryonic roots. Later in development the post‐embryonic shoot‐borne root system becomes dominant and is responsible together with its lateral roots for the major portion of water and nutrient uptake.
