The correct answer is B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife.
Explanation:
In the last decades, the creation of agricultural technology has increased the efficiency of growing crops. This means now, all the process is more efficient, which leads to more products to be sold and an increase in profit. However, the possibility of large scale agriculture has caused more land is used for this purpose. This often implies natural ecosystems such as forests are destroyed and the land of these ecosystems, which is usually rich in minerals, is used for extensive agriculture. This is a negative consequence of agricultural technology as natural areas important for wildlife are taken for human profit.
The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).
For example:
If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>

Answer:
Answer B. Endosymbiosis
Explanation:
Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.
