<span>the correct answer is B. the information that decides the characteristics of all organisms are contained in their nucleic acids. Nucleics acids are DNA and RNA. DNA have genes that code for proteins which are responsible for the structural and functional characteristics of organisms. DNA is transcribed into RNA and RNA is translated to proteins. Therefore information that is in these nucleic acids determines all the characteristics of organisms</span>
Answer:
The endocrine system assists in maintaining and regulating different functions of the body by producing and discharging hormones. It comprises glands situated throughout the body, which produce chemicals known as hormones directly into the blood. The levels of hormones in the blood are monitored by a highly unique homeostatic mechanism known as feedback.
The two kinds of feedback are common, that is, negative and positive feedback, of this positive feedback, is the rare mechanism. It augments the changes done rather than opposing them. For example, the discharging of oxytocin from the posterior pituitary gland at the time of labor is an illustration of a positive feedback mechanism.
The stimulation of the muscle contractions, which pushes the baby via the birth canal is done by oxytocin. This discharging of oxytocin leads to an augmented or stronger contraction at the time of labor. This contraction is enhanced and intensify until the baby comes out of the birth canal. However, when the stimulus to the pressure receptor terminates, the generation of oxytocin ceases, which eventually results in the stopping of labor contractions.
