In the 18th century, Carolus Linnaeus classified organisms based on their structural similarities. Modern classification determi

nes relationships more accurately because it is based on genetic and other biochemical similarities. This change in classification method best illustrates that____________.(1) multiple trials are required to increase thevalidity of a scientific explanation(2) scientific explanations are subject to theethical view of the scientist proposing them(3) peer review is required to validate the resultsof scientific investigations(4) all scientific explanations are tentative andsubject to change and improvement

Answer:

(4) all scientific explanations are tentative and subject to change and improvement

Explanation:

<em>As new facts or findings emerge about a topic, previous explanations about the topic change or are improved on. That is why findings from researches do not become a theory overnight until they have been tested by several independent researchers.</em>

Even when findings become theories, emergence of overwhelming counterclaims concerning the findings often result in change of the theory. A good example is found in Dalton's atomic theory which claimed that atoms are the smallest indivisible particle of elements. The theory was later disproved by the emergence of the fact that atoms contain proton, neutrons and electrons.

Hence, it is concluded that all scientific explanations are tentative and subject to change and improvement as new facts emerge.

MaRussiya [10]

Answer:

Generally, a seismograph consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage. The electrical voltage is recorded on paper, magnetic tape, or another recording medium.

Answer:

1. It serves as the functional unit of the nervous system. <em>b. neurons</em>

2. It collects information from the sense organ such as the eyes and the nose. <em>c. peripheral nervous  system</em>

3. It serves as the primary organ of the  central nervous system. f. spinal cord​  

4. It controls or regulates the body's internal brain environment, including the body temperature,  pulse and respiration rate, and bood pressure. <em>e. autonomic nervous  system</em>

5. It is one of the systems that is directly involved in maintaining the normal functions of cells. <em>d. nervous system</em>  

Explanation:

Neuron: Neurons are the structural and functional units in the nervous system.  Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli from other cells, and an axon that is a long formation capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis.

Peripheral nervous  system: Sense information is received by the peripheral nervous system and processed by neurons and synapses in the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons.

Spinal cord: The nervous system might be divided into the central nervous system and peripheral nervous system. There are two organs involved in the central nervous system that funtion as control centers. One of them is the brain, and the other organ is the spinal cord, surrounded by the vertebral column.  

Autonomic nervous  system: The autonomic nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system. It has too many functions in the organisms, controlling pressure, heart bitting, body temperature, sexual responses, urination, digestion, general metabolism, among others. It controls and regulates the whole organism.  

The nervous system: Homeostasis refers to stability, balance, or equilibrium. The organism needs to maintain homeostasis to guarantee the correct functioning of cells, tissues, organs, and so on. The homeostatic regulation is controlled by the endocrine system and by the nervous system, which acts as the control center.
