Answer:
The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
Explanation:
Each stack is called a granum (the plural is grana) which is suspended in a fluid called stroma. The light-dependent reactions occur in the grana; the light-independent reactions take place in the stroma of the chloroplasts.
Neurotransmitters can affect postsynaptic cells by causing molecular changes in the cells.
The term "chemical messengers of the body" is frequently used to describe neurotransmitters. The nervous system uses these molecules to send information between neurons or from neurons to muscles. A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.
When a stimulus is potent enough, the chemical messenger neurotransmitter is transferred into the nerve impulse. If it is powerful enough, it will reach the postsynaptic cell and affect the structure of the neuron. And when signal transduction happens, everything mentioned above is completed.

Answer:
Fully enclosed in an ovary
Explanation:
A gymnosperm is a group of a plant which can be distinguished from other groups of a plant is through the presence of seeds but they are not enclosed and are naked.
The seeds are considered naked as they are not fully enclosed in the ovary like in the angiosperms rather they are present as on modified leaves called sporophylls and the cones.
The seeds are sheltered by the sporophyll and when they mature are enclosed by the sporophytic tissues. Since they are not enclosed in the ovary, therefore, are considered the gymnosperms.
Thus, the selected option is correct.
Purines have 2 rings pyrimidines have 1 ring.
