Calcium channel blockers inhibit the movement of calcium ions from the interstitial fluid into cardiac and smooth muscle cells. This would cause a decrease in heart rate, stroke volume, and cardiac output. These in turn would lower blood pressure. In addition, the calcium channel blockers would also inhibit contraction of the smooth muscle in the wall of blood vessels, causing them to get wider and thus also lower blood pressure. Because both heart and smooth muscle cells are inhibited by verapamil, its effects on blood pressure are particularly potent.
Rhizomes are involved in the production of stems and “reproduction” of new plant parts. It has been theorized that rhizomes, when removed, can grow into completely new (but genetically identical) plants! It’s kind of like budding, so it’s pretty cool.
I hope I helped!
Answer:
D
Explanation:
The side not facing the sun is experiencing night because it is not receiving any light from the sun
Answer:
The correct answer will be option- three RNA polymerase
Explanation:
The RNA polymerase is the enzyme which helps the process of formation of RNA from DNA during transcription.
Prokaryotes possess only one type of RNA polymerase which form all type of RNA whereas the eukaryotes possess three types of RNA called RNA polymerase I RNA, polymerase II and RNA polymerase III.
These RNA polymerases catalyse the synthesis of different RNA in eukaryotes as RNA polymerase I help in the synthesis of rRNA, RNA polymerase II in miRNA, mRNA, snoRNA and RNA polymerase III in 5S rRNA and tRNA.
Thus, three RNA polymerase is the correct answer.
