Answer:
mutation in DNA
Explanation:
Mutations are changes in the genetic code that can occur in many ways. Each time a cell divides, say, DNA must be copied into two copies, one copy for each new cell. Although this copying is very precise, it is still not perfect - for about every billion accurately copied databases, one is mistranslated.
Another source is DNA damage, which can occur spontaneously through the normal life of the cell, or through external toxins or negative influences (ultraviolet radiation, for example). Through evolution, cells have developed a very complex system for repairing changes in DNA, but these systems not only have limitations but can sometimes cause additional errors themselves.
Answer:
The correct answer is - beetles ( coleoptera) that belongs to the arthropods.
Explanation:
There are maximum number of species in order coleoptera that belongs to the phylum arthropods. Almost 25% of total known types of life forms are beetles (coeleoptera).
The maximum numbers of known species in the U.S. are categorize into 4 distinct order coeloptera of the phylum of arthropods are-
Coleoptera (beetles) - 23,700
Diptera (flies) - 19,600,
Hymenoptera (ants, bees, wasps) - 17,500, and
Lepidoptera (moths and butterflies) - 11,500.
Thus, the correct answer is - beetles ( coleoptera) that belongs to the arthropods.
Insulin and glucagon are hormones that help regulate the levels of blood glucose, or sugar, in your body. Glucose, which comes from the food you eat, moves through your bloodstream to help fuel your body.
Insulin and glucagon work together to balance your blood sugar levels, keeping them in the narrow range that your body requires. These hormones are like the yin and yang of blood glucose maintenance. Read on to learn more about how they function and what can happen when they don’t work well.
