<h2>Monosaccharides</h2>

Explanation:

Monosaccharides are the simplest form of sugars found in innumerable common food items such as honey, cane sugar, fruits

Monosaccharides are divided into two groups depending on the presence of functional groups,if aldehyde group is present then it is known aldoses and if ketone group is present then it is known as ketoses

On the basis of carbon atoms they can be classified as: triose(3),tetrose(4),pentose(5),hexose(6) and so on

a. erythrose : tetrose ketose-It is not correctly paired because erythrose is a tetrose monosaccharide which has one aldehyde group hence is an aldose

b. dihydroxyacetone : triose ketose-It is correctly paired;it is an aldose-ketose pair

c. erythrulose : tetrose aldose-It is not correctly paired because erythrulose is a tetrose monosaccharide having ketone as functional group hence is a ketose

d. fructose : hexose ketose-it is correctly paired;It is an anomer because in D-fructose carbonyl group is at C-2 hence C-2 is the anomeric carbon

e. ribose : hexose aldose-it is not correctly paired because ribose is an aldo pentose not hexose;ribose is an aldo-ketose pair

f. glyceraldehyde : triose aldose-it is correctly paired;an aldo group

Expiratory reserve volume (ERV) You ask your lab partner to inspire a normal tidal inspiration, and breathe out a normal tidal e
Bumek [7]

The average expiratory reserve volume or ERV is 810.

<h3>What is expiratory reserve volume?</h3>
  • Expiratory reserve volume or ERV is the amount of air that is exhaled forcibly.
  • This can be measured using a spirometer and is used to detect restrictive lung diseases.
  • It is the maximum amount of air that can be exhaled after normal tidal volume is exhaled.
  • Respiratory volume is the volume of air which is either inhaled, exhaled or stored in your lungs.
  • The doctors estimate the reserve volume with the help of spirometer to determine some lung diseases.
  • Once diagnosed with a lung disease, spirometry is used to monitor it.
  • Here, 3 readings of ERV are taken, calculate the sum of the these and divide by 3 to calculate the average ERV.
  • ERV= (800+ 850+ 780)/ 3= 810

What is the function of the subplate neurons? Choose the correct option.
Semmy [17]

Answer: C) The subplate neurons attract the appropriate thalamic axons to the different parts.

Explanation:

Subplate neurons are the first developed neurons can be found in the cortex of mammals. These neurons disappear during the process of postnatal development and due to functional maturation.

These neurons are sensitive to the injury, when the humans experience cognitive and motor defects.

These neurons attract the thalamic axons and receive the synaptic inputs through the thalamic axons thus helps in establishing the link between the thalamic axons and the target layer IV. The signals are distributed from the thalamic axons to different parts of the body.
