Arthropods grow by partial shedding of their exoskeleton.

Explanation:

Arthropods grow by a process called molting or ecdysis which is shedding of their exoskeleton periodically and replacement of new bigger skeleton. Molting process usually happens along the posterior end at the tail region leading to elongation of the body.

The exoskeleton is made up of proteinaceous thin layer, epicuticle, and procuticile or inner chitin layer. This exoskeleton contains protein and minerals which makes it hard.

Although, the exoskeleton provides good protection, it becomes tough for an arthropod to grow along with the tough exoskeletion.

So, an arthropod’s body actually grows inside the exoskeleton, and as the body grows, the exoskeleton sheds off and replaced with newer ones. Molting is controlled by growth hormones like ecdysone present in their blood.

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.

Natali [406]

We can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

<h3>Why would this cause a decline in the population of coyotes?</h3>

The wolf, in most ecosystems, is considered to be the top predator. This means that it will also hunt and consume the coyotes. This alone would cause a decline in the coyote population as they now have an additional predator hunting them. Also, the wolves would be competing with the coyotes for food sources, furthering the impact on the coyote population.

Therefore, we can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

andre [41]

Answer is the phylum is Pteridophyta. Pteridophytes are first land plants, examples ferns, <em>Lycopodium, Selaginella. </em>Members have liginified cells and developed conducting tissues called vascular system to conduct water and synthesized food. They reproduce through spores, seeds do not develop in pteridophytes.
