Five major reasons why gymnosperms are more advanced than pteridophytes are highlighted below:
WHAT ARE GYMNOSPERMS AND PTERIDOPHYTES?
Gymnosperms are a group of higher plants that produce naked seeds i.e. seeds not cased by a fruit. Pteridophytes are a group of lower plants that have vascular bundles.

" The role of oxygen in the regulation of respiratory rhythm is quite significant"
Answer:
Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre. Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. A chemosensltive area is situated adjacent to the rhythm centre to make necessary adjustments in the respiratory process. Receptors associated with aortic arch and carotid artery also can recognise changes in CO
2
and H+ concentration and send necessary signals to the rhythm centre for remedial actions. The role of oxygen in the regulation of respiratory rhythm is quite insignificant.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
Explanation:
Answer:
this means that the oxygen is maintained by the respiratory rhythm.

Which of the following shows the correct energy flow during aerobic respiration?
A. Lipids, Glucose, ATP, cells
B. ATP, Glucose, cells
C. Carbohydrates, Glucose, ATP, cells
D. Carbohydrates, Glucose, Lactic acid, ATP
The correct energy flow during aerobic respiration is ATP, Glucose, and cells. Thus, the correct option is B.
What is Aerobic respiration?Aerobic respiration may be defined as the process of conversion of glucose into carbon dioxide, water, and energy via the intermediate product of pyruvate in presence of air.
The release of energy in aerobic respiration is found to be greater as compared to anaerobic respiration.
This released energy is immediately used to synthesize a molecule called ATP via glucose that fuels the cells for metabolic activities.
Therefore, the correct option for this question is B.
