Why DNA synthesis is faster than RNA synthesis?is there any advantage of being faster?
Answer:
Explanation:
I read it's has to do with the amount of nucleic acid that must be synthesized. RNAs are tiny compared to DNA, so there is little selection pressure for speed. Also, multiple RNA polymerases can initiate simultaneously, effectively increasing the synthesis rate
Answer:An obstacle to the triviality of the first issue includes the fact that DNA polymerase replicates DNA at a rate of 10-15 times faster than RNA polymerase transcribes DNA so that these enzymes inevitably collide if they attempt to function concurrently and co-directionally
Explanation:
At any given instant, only a fraction of the genome (total DNA) is being transcribed. Consequently, speed is not necessary.
Which part of the cell functions to recognize other cells? (1 point)
O nucleus
O cytoplasm
O cell wall
O plasma membrane
Answer:
cell wall maybe it may be wrong also
Plasma membrane of the cell functions to recognize other cells. Thus option D is correct.
What is Plasma membrane?The plasma membrane which is an outer covering of cell present in both prokaryotic and eukaryotic cell.
It is a thin selectively semi-permeable membrane which enclose the cytoplasm along with other organelle.
Proteins and lipids are the major components of membrane, beside this carbohydrate are also present in cell membrane.
The most common lipid in membrane is phospholipid, other lipids are glycolipid, sphingolipid.
The function of cell membrane is to provide protection and maintain the integrity of the internal environment of the cell,
It act as a base of attachment for the cytoskeleton for cell-cell communication.
It involve in transport of materials like nutrients, toxic substances.
Thus option D is correct.

Polysaccharides are synthesized in plants by condensation reactions (Option A).
Dehydration synthesis, also known as condensation, is a process by which two molecules are linked together following the removal of a molecule of water (H2O).In dehydration synthesis, two small molecules are condensed to form a large molecule in a process, thereby releasing a molecule of water.Some well-known examples of dehydration synthesis reactions are the condensation of two amino acids to produce a dipeptide or the condensation of many monosaccharides to form a polysaccharide.In conclusion, polysaccharides are synthesized in plants by condensation reactions (Option A).

" 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.

A closed system can be described as
A closed system can be described as a physical system that does not exchange matter with its surroundings, but can exchange energy.
In the context of thermodynamics and physics, a closed system refers to a system that can exchange energy with its surroundings in the form of heat or work, but does not exchange matter with the external environment. This means that the total mass of the closed system remains constant over time, as no matter is entering or leaving the system. However, energy can still be exchanged between the closed system and its surroundings.
For example, a closed container of gas that can exchange heat with its surroundings while not allowing any gas molecules to escape or enter is a closed system. Similarly, a pot of boiling water with a lid on it can be considered a closed system since water vapor (matter) is not escaping, but heat energy is being transferred through the lid. Closed systems are a fundamental concept in thermodynamics and are often used as a simplified model to analyze and understand energy exchanges without the complexities of matter flow.
