B. central nervous system.
C. endocrine system.
D. lobes of the brain.
Answer: Central Nervous System
Explanation:
The emotions such as pain, happiness, trauma and other sensory things are controlled by the brain. The things that we feel like pain, heat, cold et cetera are also controlled by the brain.
The nervous system has two parts peripheral nervous system and the central nervous system. The pain signals are carried from the knees to the brain by the central nervous system.
Answer:
It was central nervous system
Explanation:
a
It is moved by the wind toward dry areas.
b
It is incorporated into the exoskeletons of flying insects that eat plants.
c
It is inhaled and exhaled by birds roosting in trees during rainstorms.
d
It is carried by rain to the soil.
Most of the nitrogen fixed by lightning is made available to plants through d. rainwater carried to the soil.
When lightning occurs, the extreme heat breaks the bonds in nitrogen molecules, allowing nitrogen to combine with oxygen and form nitrogen oxides. These nitrogen oxides are then carried by rain to the soil, where they become available for use by plants. This process is known as nitrogen fixation, and it is an important step in the nitrogen cycle.
Thus, the fixation is a biological and chemical process where atmospheric nitrogen is converted into ammonia or other nitrogen compounds usable by plants. It's crucial for the nitrogen cycle and provides a vital source of nitrogen for plant growth, facilitated by nitrogen-fixing bacteria, lightning, or industrial processes like the Haber-Bosch method.
#SPJ2
Answer:
The lower esophageal sphincter, or gastroesophageal sphincter
Explanation:
The esophagus is a structure, part of the alimentary canal (gastrointestinal tract) that connects the pharynx to the stomach and through which the food passes. The esophagus is a fibromuscular tube that is involved in the food transport via peristaltic contractions (radially symmetric muscle contractions and relaxation).
The binomial nomenclature system used in biology for the scientific naming of organisms uses two Latin words to designate each individual species. The first word represents the genus, and the second word, the species.
Binomial nomenclature, which is used in biology for the scientific naming of organisms, uses two Latin words. These words are formed from Latin or Greek roots, regardless of the language spoken by the scientist.
The first word represents the genus, and the second word, the species. For example, the human species is scientifically named Homo sapiens, where 'Homo' is the genus, and 'sapiens' is the species.

Answer: Line A is the enzyme, and Line B is the no enzyme
Explanation:
The reaction rate of a chemical reaction is greatly impacted by the presence of an enzyme. Enzymes are biological catalysts that speed up the chemical reaction by lowering the activation energy required for the reaction to occur. Without an enzyme, the reaction rate may be slow or even non-existent, whereas with an enzyme, the reaction rate can be significantly increased.
In order to compare the reaction rate with and without an enzyme, a graph can be plotted with time on the x-axis and the amount of product formed on the y-axis. The reaction without the enzyme would have a slower rate of product formation and would result in a lower slope on the graph. On the other hand, the reaction with the enzyme would have a sharper rate of product formation and would result in a steeper slope on the graph.
It is important to note that the reaction rate with an enzyme can only be increased up to a certain point, as the enzyme can become saturated with substrate molecules. At this point, the reaction rate will plateau and adding more substrate will not increase the rate of product formation.
Understanding the role of enzymes in chemical reactions is crucial in fields such as biochemistry and pharmacology, as many drugs and therapies work by targeting specific enzymes in the body. By manipulating the activity of enzymes, scientists can alter the rates of chemical reactions and ultimately impact physiological processes.
