Answer: B. reforestation
Reforestation is the process of growing plants and trees in an area on large scale in order to create land a forest reserve which can allow the growth and abundance of floral and faunal species in future. Reforestation is the biodiversity restoration method that the biologist should use to meet their goals like : recreation of habitats for wildlife in a particular area, help against climate change as plants are the fixers of atmospheric carbon utilize this for photosynthesis and prevents the raising of atmospheric temperature.
Answer:D) increased predation and fatalities at the edge of the habitats adjacent to the road
Explanation:just did it
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.
Answer:
If an mRNA strand is 6399 nucleotides long, it will code for 2132 amino acids, as the last triplet is the terminating codon.
Explanation:
Codons are found in the RNA chain and are made up of nucleotides trios, whose specific sequence determines the genetic code.
There are 4 nitrogenous bases in RNA - Adenine, Guanine, Cytosine and Uracil - which when combined in trios give rise to 64 possible codon combinations that code for 20 amino acids, so an amino acid can be formed by more than one codon.
Determining how many amino acids are encoded according to the amount of nucleotides in the mRNA would be as easy as <u>dividing the number of nucleotids in the chain by 3</u>, but considering that the last codon is not taken into account, since it is the termination codon.
- Amino acids = (amount of nitrogenous bases in mRNA / 3) - 1
- Amino acids = (6399 / 3) - 1
- Amino acids = 2133 - 1 = 2132
