Answer:
If you tap your knee, the signal to act is carried via your somatic nervous system to the muscles in your knee. In contrast, the signals that pass via the autonomic nervous system are involuntary and act primarily to regulate your body's internal environment. This involuntary nerve system is further organized into three divisions. If you need a sudden burst of energy, your sympathetic nervous system is activated to help you act quickly. In contrast, if you are relaxing and conserving energy, then it is your parasympathetic nervous system that is primarily in action. The third division is your enteric nervous system which helps control the components of the digestive system.
Explanation:
Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:
- somatic (voluntary) nervous system-controls the movements of the skeletal muscles
- autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
- sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions)
- parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
- enteric nervous system-controls the function of the gastrointestinal tract.
Answer:DNA is antiparallel.
Explanation: DNA is a double stranded helix in which the two strands are antiparallel. Being antiparallel means that as one strand runs from 5'->3' direction, the other strand runs from 3'->5' direction. During DNA each of the two strands serves as a template for a new complementary strand. The synthesis of a new DNA strand is always in the 5'->3' direction, therefore one strand is synthesized continuously in the direction of the replication fork while the other strand is synthesized discontinuously in the direction opposite to the replication fork in short fragments called the Okazaki fragments. The strand that is synthesized continuously is called the leading strand while the strand that is synthesized discontinuously in Okazaki fragments is called the lagging strand.
Answer:
Some animals weather rocks by scraping them as they feed. Other animals change Earth's surface by burrowing into it and moving material. Too many animals in one place can destroy most of the plants, leading to faster erosion.
If too many animals graze the same land area, the animals’ hooves pull plants out by their roots. A land is overgrazed if too many animals are living there. Grazing animals can cause erosion if they are allowed to overgraze and remove too much or all of the vegetation in a pasture.

This is an inference because it’s not an observation
The correct answer is C) carboxysomes
Carboxysomes are polyhedral inclusion bodies that contain enzyme ribulose- 1,5-bisphosphate carboxylase/oxygenase (RuBisCO). This is responsible for the fixation of carbon dioxide in cyanobacteria. Carboxysomes have evolved as a consequence of the increase in oxygen concentration in the ancient atmosphere.
Thus, <em>carboxysomes are not energy reserves</em>, unlike another offered answers.
