No more than five trophic levels are present in an ecosystem, most have only 4.
Answer and Explanation:
Yes, a single molecule can work through all three effector route. Cells commonly lead independent lives, and they might influence and communicate with other cells for sexual mating. For example, yeast cells communicate with one another for mating. On the other hand, animal cells communicate by different kinds of signal molecules. These molecules include amino acids, nucleotides, proteins, small peptides, retinoid, and derivatives of fatty acids and also includes dissolved gases such as carbon monoxide and nitric oxide. In the extracellular spaces, most signal molecules are secreted by the signaling cells. Some signal molecules are exposed to the extracellular spaces, while others are released by diffusion. Target cells respond by a specific protein called receptors. Receptors bind the signal molecules and start response in the target cell. On the surface of target cells, receptors are transmembrane proteins. When receptors bind extracellular signal molecules, they stimulated and produced a flow of intracellular signals that initiate the cells' behavior.
Answer:
Explanation:
Researchers can use molecular homologies to reveal the number of mutations in a particular sequence that has occurred in each species since they diverged from a common ancestor
Answer:
Thought Blocking Syndrome
Explanation:
Thought blocking AKA Sperrung. or simply blocking is a phenomenon that occurs in people with psychiatric illnesses (usually schizophrenia), occurs when a person's speech is suddenly interrupted by silences that may last a few seconds to a minute or longer.
When the person begins speaking again, after the block, they will often speak about a subject unrelated to what was being discussed when blocking occurred. It is described as being experienced as an unanticipated, quick and total emptying of the mind. People with schizophrenia commonly experience thought blocking and may comprehend the experience in peculiar ways. A person with schizophrenia might swy that another person has removed their thoughts from their brain.
