the opposite make an attraction like positive and negative , and negative and positive. if it was negative and negative or positive and positive it wouldn't make an attraction.
The process occurring at the sensory receptors that convert physical energy into a coded neural activity that the nervous system can process is called c. sensory transduction
The ability of the sensory receptors, present inside the body of an organism, to interpret changes in the external stimuli and generate a neural activity is known as sensory transduction. The sensory receptors can interpret any change in the environment as a result of which the physical energy of the resting neurons is changed into electrical energy to transmit signals. This electrical energy is referred to as the action potential that passes along the neurons.
The CNS interprets this action potential brought by the nervous system and an action response is sent through the effector neurons.

The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
- Transcription
- Translation
During transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

Answer:
Since the sperm and egg each contribute 50% of the nuclear genetic material to the zygote that becomes the embryo, mitochondria and plastids that become chloroplasts are passed primarily from the female parent, due to a characteristic of the female gametophyte is be larger and formed from one surviving megaspore (option c).
Explanation:
The megaspore is the product of the meiosis of a megasporangio, the cula produces four structures of which only one is transformed into a megaspore.
The female gametophyte is formed from the megaspore which, being large and having a greater quantity of cytoplasm, contains the mitochondria and plastids that will originate the chloroplasts in the embryo.
