It was how fast it was disappearing. Once the world's fourth largest lake, the Aral Sea in Central Asia has been losing water for half a century — ever since Soviet engineers began diverting the two rivers that sustain it, the Amu Darya and Syr Darya, in order to grow cotton in the desert.
Answer:
D. a red allele present on at least one of two homologous chromosomes;
D. unplanned ecosystem interactions
Explanation:
A dominant allele or trait would always mask the expression of a recessive trait when both are present in a pair. The only way a recessive trait can express itself is when it is in a homozygous state. Since red color is dominant over white color in the beetle species, the genotype of any red color species would have a red alelle present on at least one of two homologous chromosomes. For example, if red allele is represented by R and white allele is r, the genotype of a red nettle species would be RR or Rr.
In the second question concerning the most reason for concern that some scientists recommends caution be taken regarding genetically modified plants is that in the process of introducing new genes into a population, unforseen and unplanned disruption of the ecosystem may occur as a result of interaction with the ecosystem that these process and it's product may present.
C. I, III & IV
they are all correct except for II because chloroplasts help with photosynthesis which doesn’t happen in animal cells
Answer:
10 (agouti) : 3 (black) : 3 (white)
Explanation:
Genotype AaBb can produce gametes AB, Ab, aB, ab.
The cross between Aa Bb × Aa Bb:
The phenotype ratio is 10 (agouti) : 3 (black) : 3 (white)
Genotypes for the agouti phenotype are: AABB, AABb, AaBB, AaBb
Genotypes for the black phenotype are: AAbb and Aabb
Genotypes for the white phenotype are: aaBB, aaBb and aabb
