The picture is not comming up
If the membrane of a cell were no longer selectively permeable then "<span>The cell would die as it would not be able to regulate which substances could enter and leave", since a selectively permeable membrane allows both things to enter and leave for the cell's survival. </span>
Answer:
the claim, evidence, and rationale
Explanation:
Answer: Option A.
Explanation:
Feathers are the epidermal growths which form the distinctive outer covering, or plumage of birds and several other vertebrates.
The major function of feather is to provide heat to the body which is possible by two ways light insulation (radiation) and conduction. In light insulation, feather of birds have the property of light scattering that allows to diffuse thermal radiation to keep the body of birds warm, results in heat conservation while in conduction, layer of air is trapped in the furs of feather which slowly heated the bodies of animals or birds.
Hence, the correct option is A.
Answer: transcription
Explanation: Transcription is a process by which an mRNA is synthesized using a DNA template. It is the process of copying the genetic message encoded in a DNA into an RNA. This process is catalyzed by an enzyme known as RNA polymerase. The RNA polymerase requires a DNA template, four oligonucleotides (ATP, UTP, CTP, and GTP) as precursors for RNA synthesis. The newly synthesized mRNA is complementary to the template strand of DNA in the sense that wherever adenine is found in the DNA template strand uracil occurs in the mRNA strand, wherever thymine occurs in the DNA template strand, adenine is found in the mRNA strand and wherever guanine occurs in the DNA template, cytosine occurs in the mRNA strand.
