Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.

Denser materials sank to the earths center and less dense materials were forced to the outer layers, forming a thin crust. Atmosphere: Less dense molecules rose to the surface. Oceans: As earth cooled, water vapor condensed to form rain which lead to the formation of oceans.

Blababa [14]

Answer:

Single-cell organisms

Explanation:

In 1735, Linnaeus introduced a classification system with only two kingdoms: animals and plants. Linnaeus published this system for naming, ranking, and classifying organisms in the book "Systema Naturae". In the epoch that Linnaeus created this system, single-cell organisms such as bacteria and protists were almost unknown. In 1866, E. Haeckel added a category including both bacteria and protozoa, thereby adding a category formed by single-cell organisms (different from animals and plants). During the 1900-1920 period, bacteria were classified as a separated kingdom named 'prokaryotes'. The current three-domain classification system was introduced by C. Woese in 1990. In this system, all forms of life are divided into three different domains: archaea, bacteria, and eukaryote domains (this last composed of protists, fungi, plants and animals).

Which of the following correctly describes how nerve impulses move throughout the body?

ikadub [295]

The correct options are as follows:
1. ELECTRICAL TRANSMISSION THROUGH NEURONS AND CHEMICAL TRANSMISSION BETWEEN NEURONS [D].
Neurons, which are the nerve cells that carry nerve impulses are made up of cell body and dendrites. Electrical events propagate signals within a neuron and chemical processes transmit the signals from one neuron to the other.
2. SENSORY NEURON - BRAIN - SPINAL CORD - MOTOR NEURONS [B].
Waking up from sleep involves sensory neurons. Hearing of a strange sound is made possible by the activity of the brain. The man become alarm as a result of the message to the body from the brain via the spinal cord and running involves motor neurons.
3. MOTOR NEURONS AND SENSORY NEURONS [A].
The peripheral nervous system is one of the two components of the nervous system and is made up of the nerves and the ganglia outside the brain and the spinal cord. The neurons of the peripheral nervous system is made up of sensory and motor neurons. The sensory neurons bring signals to the central nervous system while the motor neurons carry signals out of the central nervous system.
