Choose the answer that places the following events of protein synthesis in the proper order.
Fofino [41]

A) 3,5,1,6,2,4 is the correct order for the  events of protein synthesis.

<h3>What is protein synthesis?</h3>

Protein synthesis (translation) is the process of creating a polymer of an amino acid chain that results in the production of a functional protein. It entails reading information from mRNA (messenger RNA) and assembling an amino acid chain. Ribosomes are the structures responsible for protein chain synthesis.

Protein synthesis is an important process because we rely on our bodies to build the proteins we require to perform important functions. Without protein synthesis, our bodies will be unable to produce hormones, enzymes, and even new muscle.

Select all of the following statements that represent examples of predation. Check All That Apply Deer eat the leaves of a tree.
Fantom [35]

Answer:

A snail eats a clam.

Explanation:

Interactions always occur between organisms in an ecosystem. An interaction between two organisms is called SYMBIOSIS. Symbiosis consists other types which includes PREDATION. Predation is a kind of symbiotic relationship between two organisms in which one kills and feeds on the other in order to obtain energy. The organism that kills is called the PREDATOR while the organism that is killed is called PREY.

In this example, a snail feeding on a clam best represents the example because the snail (PREDATOR) is obtaining energy by killing the clam (PREY). In other options, no organism is killed.
