The answer is C. These structures are vacuoles and are found in plants cell (you can tell it’s a plant cell because of the outer cell wall in the picture). Vacuoles have a variety of other functions storage of waste products, maintain turgor pressure for plants support.
C. decomposer
C. from other organisms
Macroevolution can cause significant changes in the frequencies of alleles, that can ultimately result in speciation (forming of new species).
Various large-scale events like climate change and continental drift can greatly influence the distribution of species and adaptive radiation of different groups that can fill vacant ecological niches.
The changes in gene regulation and genetic mutations can also contribute to macroevolution by producing novel traits and adaptations.
All vertebrates are, by nature, in two classes : the male class and the female class. Only some invertebrates like the earthworm, water snail etc are in single class with both male and female organs in the same body.
If two recessive alleles are present the Recessive trait will be expressed.
