b. ecological footprint
c. agriculture
Answer:
Biodiversity
Explanation:
The three options given don't seem to be correct...
Sustainability is how biological systems remain diverse and productive.
Ecological Footprint is the impact of human activities measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.
Agriculture is the science of raising plants and/or animals for food, clothing or other useful products or the practice of cultivating the land or raising stock.
Biodiversity is a term that describes the number and variety of species that live in an area. It contributes to the stability and balance of ecosystems and provides ecosystem services.
Biodiversity is a term that describes the number and variety of species that live in an area. It refers to the variety of life on Earth, including plants, animals, and microorganisms. Biodiversity is important because it contributes to the stability and balance of ecosystems, and provides ecosystem services such as pollination, nutrient recycling, and water purification.

B. Helicase attaches new nitrogen bases to the ends of old DNA strands, while DNA polymerase breaks down unused DNA strands
C . DNA polymerase breaks down the old strand of DNA after a new one has been replicated, while helicase connects the two DNA strands together
D. Helicase "unzips" the DNA strand, while DNA polymerase brings in new strands of DNA to match the old strands
'Helicase "unzips" the DNA strand, while DNA polymerase brings in new strands of DNA to match the old strands.' best describes the role of helicase and DNA polymerase in DNA replication. The correct option is d.
Helicase is essential for DNA replication because it "unzips" the double-stranded DNA molecule. In order to separate the two strands and create a replication fork this process involves severing hydrogen bonds between the base pairs. On the other hand, DNA polymerase is charged with the vital task of creating new DNA strands.
It does this by incorporating complementary nucleotides into the template strands already present. This maintains genetic fidelity by ensuring that the newly formed strands mirror the original ones. The precise duplication of genetic information which is necessary for cell division and inheritance, depends on the interaction between the unwinding action of the helicase and the strand-building activity of DNA polymerase.

B) plants evolved alternation of generations independently of green algae.
C) alternation of generations cannot be beneficial to charophytes.
D) land plants evolved directly from the green algae that perform alternation of generations.
E) scientists have no evidence to indicate whether or not land plants evolved from any kind of alga.
Recent molecular evidence suggests that land plants evolved directly from the type of green algae that performs alternation of generations. This trait was likely beneficial and thus retained in all land plants.
The correct interpretation of the given observations is D) land plants evolved directly from the green algae that perform alternation of generations. Molecular systematics evidence suggests a close relationship between charophytes (a type of green algae) and land plants, however, charophytes do not exhibit alternation of generations. This implies that the trait arose after the divergence of charophytes and the lineage that led to land plants. Once land plants appeared, all of them possessed the capacity to undergo alternation of generations, suggesting this trait was beneficial and retained in the subsequent evolution.

Taking into account recent molecular systematics evidence, it is inferred that land plants evolved from the type of green algae that execute alternation of generations.
Based on the given information and considering the latest evidence from molecular systematics, it can be inferred that land plants evolved directly from the green algae that perform alternation of generations. This conclusion is drawn from the fact that both green algae (some species) and all land plants show the alternation of generations, a complex lifecycle involving two distinct multicellular stages. Charophytes, despite being a group of green algae, don’t display this trait, suggesting a different evolutionary pathway.
