Propelling neural signals is a function of neurotransmitters. a. neutral b. excitatory c. inhibitory d. impulsory

The correct answer is option b. excitatory.

The neurotransmitters are the molecules, which transfer the neural signals from one neuron to another neuron. These excitatory neurotransmitters are those neurotransmitters, which causes the excitation of the neuron it is transmitted to or the receiving neuron. So, it helps in the propulsion of the neural signals from one nerve cell to another.

The answer is B. excitatory

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

the answer is sex-linked recessive.
