A population cannot continue to increase forever because each population has a carrying capacity, which is the max number of organisms that can live in an environment with the available resources. At some point, each population will hit their carrying capacity when they run out of resources.
Answer:
c) receptor; control center; effector.
Explanation:
Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.
For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.
hi! producers are the main source of energy for consumers because they turn sunlight into chemical energy. without producers, no ecosystem would be able to survive because consumers would no longer have energy needed to live. hope this helps!
Answer:
The correct answer is (d)modified guanine nucleotide.
Explanation:
When the transcription process is finished, the guanine cap is added to the 5' end of the RNAm so it can be recognized in the cytosol and not scrapped. On the other hand, a long strand of adenines or Poly A tail is also added but to the 3' end, for the same purpose.
The difference is how much each can transport and how much the accelerated gene pools resuscitate.
