Answer:
Produce multiple polypeptide sequences from a single primary transcript.
Explanation:
Some genes produce more than one type of protein since the primary transcript encoded by these genes undergoes alternative splicing. These genes mostly have one segment that can serve either as intron or exon. Also called differential splicing, alternative splicing removes the segment as intron but retains it as an exon.
Splicing of the single primary transcript in different ways produces more than one version of mRNA from a single primary transcript encoded by a single gene. The alternative splicing allows the cells to produce multiple types of troponin proteins from single genes. These different troponin regulation muscle contraction in different muscles
Answer:
To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata. Extreme examples are plants with leaves that resemble spiky thorns or spines.
Answer:Morphology and Physiology
Explanation:Morphology studies the form,structure and features of an organism this could include the shape,height,color etc while physiology help study the underlaying factor that gives rise to the ways its functions.
This two are key for a Biology to group an organism for when the morphology is know it is possible to classify such organism.
Well oxygen has 6 electrons in its outer shell and mg has 2. Oxygen need two to complete it's outer shell and mg needs to lose 2 to gain a complete out we shell.
The correct answer is option (B) It supports the anti-drilling argument.
Deepwater drilling refers to the process of drilling holes in the deep sea, below the seabeds for the purpose of mining petroleum compounds. Deepwater horizon blowout was an explosion causing a huge oil offshore oilspill in the Gulf of Mexico, making it the largest accidental marine oil spill disaster in the world. It has a numerous negative effects on the marine life.
The toxic oil and its compounds released into the water during the deepwater horizon blowout has contaminated the water and affected the marine life including the phytoplanktons, zooplanktons, invertebrates, fishes and other mammals of the sea. Highly toxic chemical components such as benzene and polycyclic aromatic compounds have even caused DNA damage and mutations in the marine life. Apart from their mortality, it has also been responsible for reduced growth, diseases, impaired reproduction in the sea fauna. Thus, ingestion of such contaminated seafood grown in contaminated water can be held responsible for the rise in cancer rates. Thereby supporting the anti-drilling arguement.
