Patsy is explaining about the phylum Arthropoda to her daughter. Her daughter is wondering how they grow in size. What should be Patsy’s reply? A. that they grow by splitting into two halves B. that they grow by complete shedding of their appendages C. that they grow by partial shedding of their exoskeleton D. that they grow by increasing the length of their appendages E. that they grow by secreting more chitin

C. That they grow by partial shedding of their exoskeleton is the right answer.

Explanation:

Arthropoda are invertebrates. They have an external skeleton called as exoskeleton.

The exoskeleton is made up of chitin.

It can be hard or brittle and is waterproof. The exoskeleton protects the plant from drying and gives ability to live on both land and water.

The exoskeleton has great importance in arthropod growth because as they grow in size their exoskeleton is shed off and new one is formed by the process called molting.

Arthropods keep increasing layers to existing exoskeleton.

The process of ecdysis ( growth in arthropods) is necessary because the rigid and hard exoskeleton will not grow like skin and in metamorphosis when external eyes lenses are formed the hard exoskeleton will make it difficult.

located offshore, in the arctic and pacific oceans

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
