Answer:
Biological contamination is the leading cause of food-borne illness and food poisoning*, and a common cause of food spoilage and food waste. There are six types of microorganisms that can cause food-borne illness: bacteria, viruses, parasites, protozoa, fungi and prions.
Answer:
O. Living will.
Explanation:
A living will is a will made by a person stating his/ her choice of care or medication if or when the person becomes so sick and unable to communicate. In simple terms, it is a statement or directive written by a person stating his/ her desire on what type of medication or care he/she must be given when the person gets too sick and dying.
These types of will are written by individuals to give instructions or wishes to be carried out regarding end-of-life medical care and treatments that must be administered to that person. And as such, living will override other authorization papers such as organ donor cards, physician's directives, or even the power of attorneys.
Thus, the correct answer is the first option.
Answer:
Weird question but here you go lol!
Explanation:
If he is showing that he is curious to get to know you and learn more about you, this might mean that he is interested in you more than just a friend. This isn't just about him asking questions, but more so about whether or not he is listening to the things you share with him and showing that he cares about your needs.
Axons are long nerve processes which carry nerve impulses from the Soma to other neurons, they vary in length but can become almost as long as half of the human body.
The soma (body) of the neuron contains the nucleus which acts as the cell's control centre, these contain many small neurofibrils which project from the nucleus into the dendrites.
Dendrites are short, thick processes which branch out of the soma in a tree like manor. They conduct nerve impulses to the soma.
The three categories of neurons:
Afferent (Sensory) Neurons have the dendrites connected to receptors such as the eyes, ears etc. These receptors change the information they receive into electrical impulses that are transmitted to other neurons. In sensory neurons the axons are connected to other neurons.
Efferent (Motor) Neurons have the dendrites connected to other neurons, the axons are connected to effectors. Effectors are either glands or a muscle cell that is the receiving end of the nerve impulse. The nerve, when excited will cause the effector to react (move, contract, or secrete etc).
Internuncial Neurons have both the dendrites and the axons are connected to other neurons. They are sometimes referred to as connector neurons.
Internuncial neurons are found throughout the body, but especially in the spinal cord and brain.
Properties and characteristics of Neurons:
Normally the electrical impulses (messages) travel through a neuron in only one direction.
The axon may be surrounded by a 'coat' of lipids (fats) and proteins known as the myelin sheath which acts as an insulator.
Neurons are specialist cells that have lost the ability to reproduce themselves. Once the soma of a neuron has died the entire neuron dies, and can never be replaced.
Repair of damaged neurons only occurs in myelinated neurons.
white matter are coloured by myelin, consisting of many neurons supported by neuroglia.
grey matter is soma and dendrites or bundles of unmyelinated axons and neuralgia.
