The aim of this investigation is to investigate which plant will grow the tallest/actually come out of the ground (seedling),
I<span>nterneurons which are responsible for connecting one neuron to another. </span>
<span>Schwann cells are a type of glial cell that are found in the peripheral system but function similarly to Oligodendrocytes which are found in the CNS. Motor neurons carry signals from the CNS to the target or effector organ i.e. muscle or skin, while Sensory neurons carry sensory messages from receptors to the CNS. The former typically have short dendrites to receive input and long axons to carry impulses while the latter tends to have longer dendrites and shorter axons.
Hope this helps you </span>
Answer: The correct options are
--> Disinfectants are used to inhibit or destroy pathogens,
--> Disinfection can occur by physical or chemical means,
--> Endospores and viruses can resist disinfectant treatment.
Explanation:
To prevent infectious diseases from spreading or to sterilise work area surfaces during the production of drugs, chemicals known as disinfectants as used. These are chemicals that kill or inhibit the growth of pathogens. Other chemicals such as antiseptics can also kill and prevent the growth of mainly pathogenic microorganisms. However, disinfectants are stronger chemicals than antiseptics and so are often used on non-living things and surfaces.
Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores (endospores) and viruses, so it is less effective than sterilisation.
There are generally two methods of disinfection:
--> The chemical method: A typical example of a chemical disinfectant is the carbolic acid. It is used for disinfecting lavatories and floors.
--> The physical method: here, physical agents are use to disrupt and damage the pathogenic organisms on work surfaces. Some typical example include: UV irradiation, heat, sunlight exposure, sonic or hydrodynamic pressure and radiation.
Answer: Only a little colder.
Explanation: It started out much hotter, so it will stop cooling down before it reaches the same temperature as the room.
