Answer:
A) hypovolemic
Explanation:
When there is extensive bleeding, the volume of blood in the entire circulatory system decreases considerably. Therefore, the patient usually goes into hypovolemic shock.
In this type of shock the heart is unable to pump enough blood due to the large decrease in venous return. As a consequence, arterial blood pressure drops.
Answer:
Correct answer is c. It is the final electron acceptor in the aerobic respiration.
Explanation:
Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.
Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.
Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.
Answer:
The correct answer will be option D- Sensory (afferent) neurons
Explanation:
Afferent neurons are the sensory neurons which transmit the impulse from the sensory receptors of the body to the central nervous system- brain or spinal cord.
The afferent neuron receives the stimulus which generates the impulse. this impulse travels down to the interneuron where the stimulus is interpreted and response is sent through efferent neuron or motor neuron to muscle
Thus, option D- Sensory (afferent) neurons are the correct answer.
Answer:
Adequacy
Explanation:
There are four aspects of a healthy and nutritious diet, which are, balance, variety, moderation, adequacy
Adequacy in nutrition can be defined as the consumption of the needed nutrients, to reach the required amount of nutrients for attaining the best health possible. A given nutrient may be required to be taken more or less depending on the adequacy criteria.
The adequacy criteria are;
Deficiency disease prevention
Reduction or prevention of chronic diseases
Diseases associated with poor diet reduction
Maintaining physiological balance requirement.
