Answer:
The 3 Types of Hazards
Biological hazards include bacteria, parasites, fungi and viruses. They can develop in poorly handled food or through contamination from an outside source. ... Chemical hazards are harmful substances such as pesticides or machine oils. These hazards are present at every stage of food handling.(brought to you by online)
- Bacteria
- Parasites
- Fungi
- Viruses
- Salmonella (meat poisoning)
Inhibitory postsynaptic potentials differ from excitatory postsynaptic potentials most significantly in their direction of membrane polarization.
<h3>Electrical propagation in neurons</h3>
Neurons are the basic unit of the nervous system. it's transmits electrical impulses from one cell to another in form of action potentials.
The temporal change in the electric polarization of the membrane of a nerve cell (neuron) is called postsynaptic potentials. There are two types which include:
- Inhibitory postsynaptic potentials: the charge across the membrane is further from the firing threshold.
- Excitatory postsynaptic potentials: the charge across the membrane is nearer to the firing threshold.
Therefore, Inhibitory postsynaptic potentials differ from excitatory postsynaptic potentials most significantly in their direction of membrane polarization.

Answer:
Energy can usually be conserved by reducing wastage and losses. Energy is like the capacity or power to do work
It is Convergent evolution
Answer:
Reptiles and amphibians share many traits which shows that they shared a common ancestor in the past. Some of the traits that are similar in reptilia and amphibia are:
1. Both are ectoderms: Reptiles and amphibians are cold-blooded animals and they can not regulate their body temperature on their own so they take heat from surrounding to warm their body and become active.
2. Both have four legs: Both reptile and amphibians have four legs for locomotion except some animals their group.
3. Both are vertebrates: Reptiles and amphibians have vertebral column, therefore, they both come under vertebrates.
