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.
The first law of thermodynamics states that heat is a form of energy and thermodynamics processes are therefore subject to the principles of conservation of energy. The principle of conservation of energy on the other hand states that energy can neither be created nor destroyed, it can only be changed from one form to another.
The mathematical equation for the first law of thermodynamic states that
E = Q - W,
Where E = change in internal energy
Q = Heat added to the system and
W = Work done by the system.
This equation shows that, energy is conserved in the system, that is, the change internal energy of a system is a function of the heat added to the system minus the work done by the system. Thus, all the energy supply to the system has been accounted for and nothing is lost; this is in agreement with the principle of conservation of energy.
I want to say environment but Im not sure. I hope this was helpful though.
Answer:I'm pretty sure the answer is a or c for asexual reproduction.
Explanation:Because these are all types of asexual reproduction.
May be eukaryotic. I hope this helps!
