Topic: Biology, Excretory Products and their Elimination, NEET
Select the incorrect statement.

Options:
A Every 100 ml of deoxygenated blood, delivers approximately 4 ml of CO2 to the alveoli.
B Carbonic anhydrase is present in very high concentration in RBC.
C High pCO2 and low pO2 in tissue help in binding of carbon dioxide.
D CO2 is carried in haemoglobin as carboxyhemoglobin.

The correct answer is:
CO2 is carried in haemoglobin as carboxyhemoglobin.

Solution:
CO2 is carried by haemoglobin as carbamino-haemoglobin (about 20-25%). This binding is related to the partial pressure of CO2. pO2 is a major factor which could affect this binding. When pCO2 is high and pO2 is low as in the tissues, more binding of carbon dioxide occurs whereas, when the pCO2 is low and pO2 is high as in the alveoli, dissociation of CO2 from carbamino-haemoglobin takes place, i.e., CO2 which is bound to haemoglobin from the tissues is delivered at the alveoli.

RBCs contain a very high concentration of the enzyme, carbonic anhydrase and minute quantities of this enzyme is present in the plasma also and every 100 ml of deoxygenated blood delivers approximately 4 ml of CO2 to the alveoli.

Topic: Biology, Respiration in Plants, NEET
Select the incorrect statement.

Options:
A Linkage is inversely proportional to independent assortment.
B Persons affected by PKU do not show mental disorders.
C The F2 phenotypic and genotypic ratio is the same in incomplete dominance.
D In dihybrid, cross each character inheritance resemble a monohybrid cross.

The correct answer is:
Persons affected by PKU do not show mental disorders.

Solution:
Phenylketonuria:
Cause: This inborn error of metabolism is also inherited as the autosomal recessive trait. The affected individual lacks a liver enzyme called phenylalanine hydroxylase that converts the amino acid phenylalanine into tyrosine. The genes for the disease are located on chromosome no. 12.
Symptoms: Since phenylalanine is not converted, phenylalanine is accumulated and converted into phenylpyruvic acid (keto derivative) and other derivatives. Accumulation of these in the brain results in mental retardation. These are also excreted through urine because of its poor absorption by the kidney.
Treatment: Diet rich in tyrosine and lacking phenylalanine.

B Insertional inactivation of Î²- galactosidase leads to the formation of colourless colonies.
C Insertional inactivation of Î²- galactosidase leads to the formation of blue color colonies.
D In insertional inactivation, the rDNA is inserted within the coding sequence of an enzyme Î²- galactosidase.

The correct answer is:
Insertional inactivation of β- galactosidase leads to the formation of blue color colonies.

Solution:
Selection of recombinants due to inactivation of antibiotics is a cumbersome procedure. Therefore, alternative selectable markers have been developed, which differentiate recombinants from non-recombinants on the basis of their ability to produce colour. A recombinant DNA is inserted within the coding sequence of enzyme β-galactosidase. This results in insertational inactivation, and the colonies do not produces any colour.

Select the incorrect statement.

Options:
A Digestive system is complete in Aschelminthes and Echinodermata but not in Platyhelminthes.
B Segmentation is present in Annelida and Arthropoda but absent in Chordata.
C Organ system level of organisation is found in Aschelminthes and Annelida but not in Ctenophora.
D Circulatory system is absent in Platyhelminthes and Aschelminthes but present in Hemichordata.

The correct answer is:
Segmentation is present in Annelida and Arthropoda but absent in Chordata.

Solution:
Metameric segmentation is found in annelids, arthropods and chordates. In metameric segmentation, there is a linear repetition of body parts where each repeated unit is called somite (metamere).
In earthworms, the successive somites are essentially similar, but they are dissimilar in different body regions of a crayfish or insect. Metamerism is conspicuous both externally in annelids. It is mostly external in arthropods and internal in humans and in other chordates (vertebrate, body muscles, some blood vessels and nerves).

Options:
A Algin is obtained from Algae.
B Cyanobacteria form mycorrhizae which helps in the absorption of phosphate
C Salvinia, Selaginella and Azolla show heterospory.
D The genome of TMV is RNA.

The correct answer is:
Cyanobacteria form mycorrhizae which helps in the absorption of phosphate

Solution:
"Myco" - "rhiza" literally means "fungus" - "root" and describes the mutually beneficial relationship between the plant and root fungus. These specialized fungi colonize plant roots in a symbiotic manner and extend far into the soil. Mycorrhizal fungal filaments in the soil are truly extensions of root systems and are more effective in nutrient and water absorption than the roots themselves. Cyanobacteria on the other hand is not a fungus.
