The given question is incomplete. The complete question is:
All of the flower mechanisms would help prevent pollination by a foreign species except __________.
A. A pollen tube grows in the style of its own species.
B. The stigma is sticky mainly to its own species of pollen.
C. The timing of flowering keeps pollinators moving among a limited number of species.
D. Flowers attract a small number of specialized pollinators, and therefore pollen is not spread equally to all available species of flowers.
E. Flowers of different species are the same color and attract similar pollinators.
Answer:
E. Flowers of different species are the same color and attract similar pollinators.
Explanation:
Plants of different species develop various morphological, physiological and behavioral strategies to ensure that the flowers of one species are not pollinated by pollens from any other species. One such structural adaptation is the production of flowers of a different color, size and shape.
These structural distinctions allow specific pollinators to visit the flowers of the particular species only. It ensures pollens from a different plant species do not land on the flowers of some other species. Production of flowers of the same color by different plant species would attract same pollinators and may result in pollination by a foreign species.
Nucleic acids provide the blueprint for the construction of proteins, the third statement best describe the relationship between proteins and nucleic acids.
The primary information-carrying molecules in the cell are Nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two main forms of nucleic acids. DNA is the genetic substance of all free-living creatures and the majority of viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays a crucial part in activities such as proteinsynthesis.
The mRNA (messenger RNA) receives the genetic information of the proteins from the DNA (Deoxyribonucleic acid) and gives it to the ribosome (which generates proteins), so that the ribosome may produce proteins based on the 'blueprints' that came from the DNA.
Thus, the third statement best describes the relationship between proteins and nucleic acids.
