love history [14]

Answer:

Option (4)

Explanation:

The earth is comprised of numerous lithospheric plates. This lithosphere is comprised of dozens of major plates and a few minor plates. These plates are constantly in motion over the less dense asthenosphere layer where the rocks tend to flow during deformation. This plate motion takes place due to the creation of convection current in the mantle region as a result of which the plates move under the influence of uprising magma. These currents are formed because of the heat supplied from the core of the earth.

Some of the major plates are Indo-Australian plate, North American Plate, South American plate and the Pacific plate.

Some of the minor plates include the Cocos plate, Nazca plate, and Caribbean plate.

Thus, the correct answer is option (4).

What is the function of the nervous system? What is the basic unit of the nervous system?
Sidana [21]

Answer:

Illustration of the architecture of a neuron, including the cell body, nucleus, dendrites, axon, myelin sheath, node of Ranvier, synapses, and axon terminal. ( the photo with the answer )  

The nervous system has two main parts:

The central nervous system is made up of the brain and spinal cord.

The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

The nervous system transmits signals between the brain and the rest of the body, including internal organs. In this way, the nervous system’s activity controls the ability to move, breathe, see, think, and more.

The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons. A neuron has a cell body, which includes the cell nucleus, and special extensions called axons and dendrites. Bundles of axons, called nerves, are found throughout the body. Axons and dendrites allow neurons to communicate, even across long distances.

Different types of neurons control or perform different activities. For instance, motor neurons transmit messages from the brain to the muscles to generate movement. Sensory neurons detect light, sound, odor, taste, pressure, and heat and send messages about those things to the brain. Other parts of the nervous system control involuntary processes. These include keeping a regular heartbeat, releasing hormones like adrenaline, opening the pupil in response to light, and regulating the digestive system.

When a neuron sends a message to another neuron, it sends an electrical signal down the length of its axon. At the end of the axon, the electrical signal changes to a chemical signal. The axon then releases the chemical signal with chemical messengers called neurotransmitters into the synapse     the space between the end of an axon and the tip of a dendrite from another neuron. The neurotransmitters move the signal through the synapse to the neighboring dendrite, which converts the chemical signal back into an electrical signal. The electrical signal then travels through the neuron and goes through the same conversion processes as it moves to neighboring neurons.

The nervous system also includes non-neuron cells, called glia . Glia perform many important functions that keep the nervous system working properly. For example, glia:

1-  Help support and hold neurons in place

2- Protect neurons

3- Create insulation called myelin, which helps move nerve impulses

4- Repair neurons and help restore neuron function

5- Trim out dead neurons

6- Regulate neurotransmitters

The brain is made up of many networks of communicating neurons and glia. These networks allow different parts of the brain to “talk” to each other and work together to control body functions, emotions, thinking, behavior, and other activities.

A scientist investigated whether giving plants different quantities of magnesium affected their growth. He
liberstina [14]

The hypothesis that the scientist could test in his investigation is as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.

<h3>What is an hypothesis?</h3>

Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation.

An hypothesis is commonly referred to as an educated guess because it tends to provide a temporary explanation for a phenomenon.

According to this question, a scientist investigated whether giving plants different quantities of magnesium affected their growth. He measured growth by counting the number of new leaves produced.

The hypothesis of the scientist regarding the above experiment could be as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.
