Answer:
To achieve precipitation of the DNA.
Explanation:
Isopropyl alcohol makes the DNA sediment. The DNA, once out of the solution, becomes visible, as it clumps.
The result of adding isopropyl alcohol is the precipitation or sedimentation of DNA when DNA becomes like a visible thread with the help of alcohol and salt. The precipitation of DNA is important because it removes the dirt from DNA.
The a and b alleles when present together as ab is, both alleles are expressed so it is co-dominant alleles.
Answer:
Cacti
Explanation:
The well know desert plant Cacti have been a very interesting speciman in terms of survival and its adaptation to its enviornment in order to succeed in the game of survival.
- In order to maintain the moisture within the plant, its leaves are in the shape of needles which can lead to less water evoporating from the plant.
- The inners of Cacti have been modified to store water for prolonged periods of time in order to survive the long periods of drought and lack of water.
- The structure and outer skin of the Cactus has been able to help them once again maintain water levels within itself as traits such as waxy and thick skin cover the entirety of the plant.
Answer:
Fat molecules contain more energy-containing bonds than simple sugars.
Explanation:
Lipids are a large group of mostly non-polar hydrophobic hydrocarbons. They include fats and oils, waxes, phospholipids and steroids. They serve many functions in living organisms such as energy storage molecules, information molecules, insulation against cold in some animals etc.
From the information provided above, lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. When energy provided per gram by lipids is compared with that of either glucose or glycogen, lipids provide more than twice the energy of that of glucose or glycogen. Similarly, the energy storage capacity of lipids over 1000 times that of glucose and 50 times that of glycogen. Therefore, fat molecules (an example of lipids) contain more energy-containing bonds than simple sugars (e.g. glucose)
Answer:
Secondary succession in healthy ecosystems following natural disturbances often reproduces the original community, however ecosystems may not recover from human-caused disturbances. Ecological succession is a series of more-or-less predictable changes that occur in a community over time.
