Answer:
The correct answer is a. absent spinal reflexes below the level of injury.
Explanation:
Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.
Water is essential to life because it creates us humans, plants, animals, etc. So, if we find water on Mars it would be important because water is essential to life, meaning we would know that there would be some kind of life on Mars because water makes up anything.
The dead organisms are recycled back by the activity of decomposing or decomposition. I hope this helps!
The answer is B) Weathering occurs when rocks are subjected to the movement of wind and/ or water.
Explanation:
A) Cannot be A) because there’s actually 5 different types of weathering. Physical, chemical and biological.
Cannot be C) because weathering is caused by nature.
Cannot be D) because that would be Erosion.
The processes and their reactions are discussed below.
<h3><u>
Explanation</u>:</h3>
<u>Carbon dioxide</u>:
In case of plants the carbon dioxide is needed to produce glucose in the process of photosynthesis. This step is very crucial for the survival of each and every organisms in the living world. The energy for this process of photosynthesis is found from sun's rays.
In case of humans, carbon dioxide is produced through respiration. This produces energy that helps the organism to sustain living.
Oxygen:
It is produced by plants from photosynthesis through splitting of water. The energy for this process comes from Sun's energy.
In case of animals, the oxygen is needed for respiration. This is required to accept the electron in the last step of aerobic respiration. This produces the energy that helps to sustain the living.
Water:
Both plants and animals require the water for performing their metabolic works. The water is obtained by plants from soil through roots and conducted to leaves by vascular tissues xylem. Similarly the animals obtain water from drinking. They need the water to perform digestion, and each and every metabolic process.
Glucose:
Glucose is produced by plants from photosynthesis. It is produced absorbing the energy of Sun's rays.
In case of animals, the animals obtain glucose from food and they digest the glucose through respiration and produce energy that helps them to sustain life.
