Answer:
The correct answer is : * Membrane carbohydrates function primarily in cell-cell recognition.
Explanation:
The carbohydrates (poly or oligosaccharides) associated with the plasma membrane, are covalently bound to it (to proteins or lipids). They are found in the outer part of the plasma membrane forming the glycocalix. Its main functions are:
-Cell recognition
-Support to the membrane.
Answer: Confirm the presence of alcohol in an individual.
All of the above
Determine the role that tolerance may play in a case.
Explanation:
The field sobriety test is a standard field test which is done by the police officer to determine whether the person suspected of impaired driving is intoxicated with drugs or alcohol. This confirms the presence of alcohol in an individual driver.
Metabolism is a process of conversion of complex food particles or drugs or alcohol into water soluble metabolites so that these can be excreted out from the body readily. The metabolism process deactivates the potent drug, it converts the drug into substances which can be used for producing energy for metabolic reactions. The ethyl alcohol is also converted into acetic acid which is less potent metabolite, which can be excreted out from the body.
A forensic toxicologists is a scientists who performs the laboratory based tasks for identify the origin and concentration of drugs. They also determine the conversion of drug into metabolites in the body. Such a scientists have no role in observing and determining the tolerance of drug in a particular case this is the role of forensic psychologists.
<h2>
Answer</h2>
Stimulus ➡ Touch Receptor ➡ Sensory Nerve cell ➡ Relay nerve cell ➡ Muscle ➡Response
<h2>
Explanation</h2>
- When a body touches a hot or very cold body, a stimulus is generated.
- Touch receptors convert this stimulus into a nerve impulse and transmit it to the sensory neurons located in the spinal cord (CNS) via peripheral nerves.
- The impulse travels across a synapse to relay neurons
- Relay neuron passes impulse across the second synapse to motor neurons.
- Now impulse travels along motor neuron to reach the effector (muscle)
- Muscle contract and hand is withdrawn quickly (Response)
