Answer:
paracrine signaling.
Explanation:
Chemical signaling between cells is one of the most important ways that activities of tissues and organs are coordinated. The nervous system is the other major coordinating system in animals, but even here chemical signaling is used between adjacent neurons. The mechanisms involved are described as either being paracrine, autocrine, intracrine, endocrine, neuroendocrine or pheromones. Paracrine signals diffuse locally and act on neighboring cells.
Answer:
The correct answer is option C- "Sublingual space".
Explanation:
If an infection perforate from he mandibular first premolars through the lingual cortex, it is very likely that it continues is way into the sublingual space. The infections located at the sublingual space are often bacterial infections that comes precisely from the floor of the mouth. If an infection goes into the lingual cortex, it will often go to the tissue under the tongue at the sublingual space.

Answer:
Ego
Explanation:
In 1923, Sigmund Freud's personality theory was structured into three different parts viz: Id, ego and superego
The id is the instinctive and unconscious part of the personality which responds directly to urges, needs and desires. The id operates on the pleasure principle that every wishful impulse should be satiated instantly regardless of the resulting effect.
The ego is the part that mediates between the unreasonable id and societal beliefs. It is the reasoning and decision-making component of the psyche.
The superego is the part that acts as a self critical conscience, reflecting the social standards that has been learnt
In this scenario involving Cecil, the id part of his personality is responsible for the sexual attraction to his English teacher but the ego part of his personality is making him realize that is socially unreasonable for his teacher to respond to his sexual advances. His ego, which operates with the reality principle is restraining him from acting from his feelings in consideration of social realities.
Therefore, his ego is restraining him from expressing his feelings of sexual attraction (Id) considering societal consequences.
1. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a tRNA.
tRNA are molecules involved in protein synthesis (translation) and those molecules connect codons from mRNA with the amino acids they encode.tRNA has anticodone that binds to mRNA codone.
2. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called translation.
Translation is a process of gene expression in which proteins are synthesized (translated from the codons on mRNA).
3. Initiation of translation always happens at the start codon of the mRNA.
Translation process can be divided into three stages: initiation (starting off), elongation (adding amino acids to peptide chain that is going to become protein) and termination (finishing up).
4. Amino acids are attached to tRNA by enzymes called aminoacyl-tRNA synthetase.
These enzymes are part of the elongation stage of translation and they catalyze the adding of amino acids.
5. Termination of translation happens when the ribosome hits a stop codon on the mRNA.
Termination is the stage in which the finished polypeptide chain (future protein) is released from the ribosome.
