antiseptic1488 [7]

Answer:

IV, VI, III, I

Explanation:

Translation is the process of synthesis of protein from with the help of messenger RNA (mRNA).

The process of translation include initiation, elongation and termination.

  • Initiation: In this step mRNA binds to ribososomes and tRNA, carrying start codon or methionine binds to mRNA.
  • Elongation: In this step, the tRNA molecules carrying several amino acid bind to mRNA based on the sequence of mRNA codon and then moves (translocates) to the next mRNA codon which leads to amino acid chain.
  • Termination: At the end, when a stop codon (UGA) identified, polypeptide is released.

So, the correct chronological order is IV, VI, III, I.

Stels [109]

:

A flea and dog are an example of parasitism, because the flea irritates the dog's skin and feeds on its blood.

In a parasitic interaction, one organism benefits whereby the other one harmed. It is a positive - negative relationship. This interaction involves the interaction between the host and the parasite. The host is the bigger organism, here, the dog that is being harmed. The parasite is the flea causing the harm and benefiting from the relationship.

Certain bacteria live in the digestive tract of humans, and their relationship is an example of because mutualism the bacteria help humans to break down the food they eat.

In mutualism, the interaction is based on both organism deriving benefit from one another. Here, the bacteria gets its nourishment by breaking down human food. Human beings are able to digest the food better and are also nourished. A win-win situation is established.

Cattle egrets eat insects off the back of an elephant, which is an example of commensalism because the cattle egrets benefit without either harming or helping the elephants.

This relationship is known as commensalism in which one organism derives benefit. The other one derives no benefit and it is also not harmed in the process. The egrets feeds on the insects that are not harming the cattle.

Which would be an adaptation in a rain forest, but not in a desert?
yanalaym [24]

<u>ANSWER:</u>

The correct option is C: Skin that blends with green plants. Most animals in rain forests are green so that they can camouflage and appear like plants.

<u>EXPLANATION:</u>

  • Adaptation is the way in which animals survive in different climatic conditions and different regions. In rain forests, to protect themselves and to find food, most animals are green in colour.
  • This prevents the animals from being spotted easily and therefore they are protected from hunters and other animals that eat them. This way, the animals can also find their prey and catch it easily.
