Answer: The correct answer is C) DNA.

DNA ( deoxyribonucleic acid) is the genetic material of all life forms. It carries information in the form of nucleotide sequences. DNA is transcribed into mRNA ( messanger RNA), which is then translated into specific proteins. mRNA contains sequences in the form of codon ( a triplet code of nitrogenous base for specific amino acid)

As mRNA is transcribed from DNA. Thus, instructions for making proteins originally comes from DNA.

According to the Central Dogma, genetic information is passed in this order-

DNA→ mRNA→ Protein

30.Of the following, which component of life is the largest?
ipn [44]

Answer: 30. D. Cell

31. A. Tissue

32. D. Biome

33. A. Population

34. D. Condensation

35. B. Precipitation

Explanation:

30. A cell is a largest component of life among the options given. As it includes within it molecule, and organelles required for the functioning and metabolism of cell.

31. A tissue is the smallest component of life. It is made up of group of cells. The cells combine together in tissue to perform a specialized function in organisms.

32. Biome is the largest ecological group which includes diversity of living organisms interacting with the physical environment. The biome is characterised by abiotic factors like climate, temperature, geography, and soil and also by the biotic factors such as flora and fauna.

33. Population is the smallest group which includes the members belonging to the same species living in the same location or region. These members are capable of inbreeding among themselves and producing viable offsprings.

34. Condensation is a process in which the water vapors being in high temperature cools down in the sky to form clouds. It is the part of water cycle.

35. Precipitation is the part of the water cycle. In this the clouds formed after the condensation process, due to increase in amount of water vapors in them the water falls off under the effect of gravity. The precipitation is in the form of sleet, snow, hail, drizzle and rain.

You go for a run and breathe heavily for an extended amount of time. How is this affecting your pH levels?
monitta

You will run and breathe heavily for a long period of time. is affecting your pH levels, Lowering the pH, making it more acidic.

  • A. Lowering the pH, making it more acidic.

<h3>How does respiratory rate affect pH?</h3>

When it is respiratory, it occurs due to an increase in the amount of volatile acids in the body, which lead to an increase in pCO2. When it is metabolic, it occurs due to the accumulation of non-volatile acids, which lead to the loss (excessive consumption) of bases, mainly bicarbonate, causing a drop in pH.

With this information, we can conclude that By eliminating carbon dioxide during expiration, pulmonary ventilation reduces the acidity of the blood, helping it to maintain the desired alkalinity level.
