Meiosis increases genetic variation due to random segregation which occurs.
In anaphase I of meiosis, the homologous pairs (one maternal and one paternal chromosome) are moved apart to opposite ends of the cell and this process occurs random. This allows the formation of gametes with different sets of homologues. In this phase sister chromatids remain attached at their centromeres (not segragated as in mitosis).
Plants changing sun energy to food
Answer:
The process is termed as sequence assembly.
Explanation:
The aligning and merging fragments from a longer sequence of DNA so that the original sequence can be redeveloped is termed sequence assembly in bioinformatics. The process of sequence assembly is essential as the DNA sequence technology fails to read the complete sequence of genomes in one go, and apart from that, it reads small fragments of DNA sequences between the sizes of 20 to 30000 base pairs.
The finches on the Galapagos Islands are a good example of adaptation because they all trace their ancestry into a small group of finches that inhabited these islands, but diversified in accordance to the environment. On the Galapagos Islands, there are finches that have numerous types of different beak shapes and sizes, despite them all being derived from a single group of finches that had the same characteristics. The reason for this is that once they got to these islands, there were multiple niches int the food chain that were free for taking. Some finches started to feed on plants, some on seeds, some became insect-eaters etc. Every food type needs special adaptation so that the finches can eat it more easily, or even be able to get to its nutritional part, thus their beaks started to change in accordance to their food preference.
The correct answer is AMDR or Acceptable Macronutrient Distribution Ranges.
DRI or Dietary Reference Intakes is defined as recommendent amount of energy, nutrients and other food components for healthy people to stay healthy and to prevent chronic disease risk, and deficiencies. DRI is set for each gender and age.
