Alveolar gas partial pressures change as Oxygen partial pressure increases in the lungs and the partial pressure of carbon dioxide decreases.
Because the artery is blocked, you will not be able to effectively exchange O2 and CO2; consequently, you will have greater partial pressure of O2 in the lungs than you normally would, and artery cannot effectively supply the CO2 that was produced to get expired, resulting in a decrease in CO2 partial pressure. Ventilation is unaffected, meaning that you are still breathing normally (no problem with inspiration or expiration).

What is used as a template for the construction of a new RNA molecule?
DNA strands
The process of Transcription begins with the opening and unwinding of a small portion of the DNA double helix to expose the bases on each DNA strand. One of the two strands of the DNA double helix then acts as a template for the synthesis of an RNA molecule. Transcription is the process by which DNA sequences in genes are copied to make RNA.the process ends in the process called termination which is dependent on the sequence of the RNA created.Three different types of RNA polymerase exist in eukaryotic cells, whereas bacteria have only one. In eukaryotes, RNA pol I transcribes the genes that encode most of the ribosomal RNAs (rRNAs), and RNA pol III transcribes the genes for one small rRNA, plus the transfer RNAs that play a key role in the translation process, as well as other small regulatory RNA molecules. Thus, it is RNA pol II that transcribes the messenger RNAs, which serve as the templates for production of protein molecules

Which type of reproduction produces offspring that are clones with the exact same DNA as the parents?
Asexual reproduction produces offspring that are clones with the exact same DNA as the parents.
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in number of chromosomes. Asexual reproduction involves mitosis instead of meiosis. This type of reproduction is observed in both multicellular and unicellular organisms.
In the process, of asexual reproduction, only one parent is involved and there is no fusion of male and female gametes. Thus, the offspring produced are morphologically and genetically similar to parents. Therefore, they are called clones.
In asexual reproduction, the offspring are produced which are exact copies of their parent. Animals reproduce in two ways, sexually i.e., two parents are involved and asexually i.e., only one individual contributes genetic material.

What is a silent mutagen?
Silent mutagens are substances that can cause silent mutations.
Mutations are changes in genetic material both at the gene and chromosome levels during DNA replication that can be passed on to their offspring. Mutations can be caused by internal or external factors that cause changes in the protein produced.
Silent mutagens are materials or factors that resemble nitrogenous bases that can cause silent mutations. Silent mutations occur due to codon changes caused by mutagens that do not cause amino acid changes. This mutation occurs due to a change in the base pair of the gene at position 3 of the codon resulting in a change in one genetic code but does not result in a change in the amino acid.

you wish to obtain a pure mitochondria sample from lysed cells. the best way to obtain this sample would be
The best way to obtain a pure mitochondria sample from lysed cells is to perform differential centrifugation.
This is a multi-step process in which the lysed cells are first spun at a low speed to remove large cellular debris. The supernatant is then spun at a higher speed, which causes the mitochondria to pellet due to their heavier weight.
The resulting pellet can then be washed and re-suspended in a suitable buffer to obtain a pure mitochondria sample. Additionally, other purification methods such as sucrose gradient centrifugation or sucrose cushion centrifugation can also be used to obtain a pure mitochondria sample, but differential centrifugation is the most commonly used method.
It is important to obtain a pure mitochondria sample for downstream experiments such as enzymatic assays, protein analysis, and gene expression analysis, as contaminants from other cellular components can interfere with the results.
