The group of organisms that survived mass extinctions that marked the ends of both the Paleozoic Era and the Mesozoic Era is the gastropods. Gastropods are one of the most diverse groups of animals, both in form, habitat, and habit. They are by far the largest group of molluscs, they include snails and slugs of all kinds and all sizes from microscopic to Achatina achatina.

Which events can cause an ecological disturbance? Select the three correct answers.

kvasek [131]

A, B and C are the events that will cause an ecological disturbance.

Rationale:

A. Introduction of a new species: When a new specie is introduced, it increases the competition in ecosystem with the native species for food, water, space and shelter. This affects the reproductive success of the native species and thus the dynamics of ecosystem.

B. Climate change: Climate change is different from a simple change of weather. The best example would be of Antarctica where the ice is melting fast due to the global warming. The native species find it harder to adapt to the warm temperatures.

C. Late spring snowstorm: Spring is the season where the plants grow and animals shed their fur. When snowstorms occur in this season they harm these plants and animals that live there.

During bacterial translation, initiation occurs in three steps. Which step is last?.

Olegator [25]

Bacterial translation is initiated in three steps. In the final step, the large ribosomal subunit binds to the mRNA.

The ribosome's translation of an mRNA molecule occurs in three stages: initiation, elongation, and termination. The small ribosomal subunit binds to the beginning of the mRNA sequence during initiation. Most eukaryotic mRNAs initiate translation by binding Met-tRNAiMet to a 40S subunit, followed by ribosomal attachment at the 5′ end of an mRNA, scanning to the initiation codon, and joining with a 60S subunit to form an 80S ribosome. The stages of translation should be completed in the following order: Initiation, Elongation, and Termination.
