Geologists have divided the earth history into time units that are largely based on the earth's biotic composition. The modern geological time scale includes both relative and absolute age dating and represents the most up-to-date assessment of the earth's history.
In the modern geological time scale, the eras in earth's history when the planet was populated with advanced life forms are referred to as the Paleozoic (meaning ancient life), the Mesozoic (meaning middle life), and the Cenozoic (meaning recent life).
Some ways that plants are transported around include seeds, insects, people, and animals.
The subtrate will no longer fit within the enzyme because the heat will cause the enzyme to denature (deform).
<h3>Enzyme </h3>
Proteins called enzymes serve as biological catalysts (biocatalysts). Chemical reactions are sped up by catalysts. Substrates are the molecules that enzymes can interact with, and the enzyme changes the substrates into new molecules known as products. Almost all cellular metabolic activities require enzyme catalysis in order to proceed at speeds quick enough to maintain life. Enzymes are necessary to catalyze specific steps in metabolic pathways. Enzymology, the study of enzymes, and the pseudoenzyme analysis area acknowledge that some enzymes have lost the capacity to perform biological catalysis during evolution, which is frequently reflected in their amino acid sequences and peculiar "pseudocatalytic" capabilities.

Answer:
C: If crossed with another heterozygous plant, the majority of progeny will have the dominant flower color.
Explanation:
Assuming the gene is represented an allele A, purple colour can be AA or Aa while white colour will be aa.
If a heterozygous plant Aa is crossed with another heterozygous Aa, the genotype of the progeny will be AA, Aa, Aa and aa.
Since allele A is dominant over a, it thus means that the phenotype of the progeny will be 3 purple and 1 white flowered plant.
<em>Hence, the majority of the progeny will have the dominant (75%) flower colour.</em>
The correct option is C.
