Answer:
true
Explanation:
When your eyes are not covered and you are in an area with good lighting, then opening your eyes would certainly be a necessary thing to do to be able to see and this makes your vision to be normal.
According to Leo Gross, you can have a normal vision if you are 20 feet away from a particular spot and you see what a normal person sees on that same spot. There is the Snellen chart one is also expected to read in that position, so maintaining a normal vision means someone has 20/20 vision.
Answer:
<h2>Postsynaptic </h2>
Explanation:
Acetylcholine receptor is a kind of integral membrane protein that has a very important role in the binding of neurotransmitters such as acetylcholine and some other. Generally, these receptors are present on the postsynaptic cells to receive acetylcholine neurotransmitter to initiate the signal in the neurons cells and some other.
Acetylcholinesterase is a kind of important enzyme that has many important functions in the dissociation of acetylcholine and some other that function as neurotransmitters. This enzyme is also present in the postsynaptic cells.
Domain of unicellular prokaryotes that have cell walls containing peptidoglycan; corresponds to the kingdom Eubacteria. Domain consisting of unicellular prokaryotes that have cell walls that do not contain peptidoglycan; corresponds to the kingdom Archaebacteria.
Answer:
NADH, pyruvate.
Explanation:
The fermentation process occurs in the cytoplasmic matrix.
Thanks to the H+ that are recovered from the oxidation of NADH to NAD +, they bind to pyruvic acid to change its conformation and transform it into lactic acid.
Two types of fermentation occur:
- Lactic
- Alcoholic, which releases ethanol + CO2
This is the reaction:
C6H12O6 + 2 Pi + 2 ADP + 2 NAD → 2 CH3-CH2OH + 2 CO2 + 2 ATP + 2 NAD
Answer:
a. autoclaving
Explanation:
The autoclave is a device designed to sterilize contaminated material and media, in order to reliably eliminate microorganisms that would otherwise be present in objects that are used in diagnostic, treatment or research activities in hospitals and laboratories health institutions . This sterilization is usually carried out with moist heat in devices called autoclaves. It is also a widely used equipment in the food industries and in the pharmaceutical industry.
For sterilization of culture media to be effective, the selected temperature and time must be achieved throughout the liquid. Since the transmission of heat in the liquid of the vessels is carried out from the outside inwards, it is evident that the efficiency of the process will depend on the volume of liquid.
In general, it is not convenient to sterilize large and small containers together. In any case, the temperature and time will be selected according to the volume of the containers.
Hermetically sealed containers must be introduced into the autoclave without completely closing the cap, to facilitate the entry of steam during the process. When emptying the autoclave after sterilization we will proceed to completely close these containers.
Empty containers require a longer sterilization time than containers with liquid inside.
The autoclaves are available in many sizes, the small ones are desktop and the larger ones are complex equipment that require a large amount of pre-installation for their operation. In order to measure its size, the volume of the sterilization chamber is usually taken as a reference, which is measured in cubic centimeters or liters. Depending on their operation they are semi-automatic or automatic.
