Answer:when visiting the Channel Islands, you can't help but be amazed by creatures such as the island fox, night lizard, deer mouse, island scrub jay, and ashy storm-petrel, just to name a few of the endemic species. The Channel Islands were also once home to the pygmy mammoth, a now extinct dwarf elephant that evolved in this insular environment.
Along with these endemic species are many of what biologists call invasive species, species that originated from elsewhere but have found a home in the Channel Islands. These include sweet fennel, olive trees, and Australian blue gum trees. For a time, elk and deer could also be found here as well.

True
Explanation:
Lewis structures are diagrams that represent the valence electrons of atoms within a molecule. These lewis structures help visualize the valence electrons of atoms and molecules, whether they exist as lone pairs or within bonds.
Answer:
The correct answer is "All of these are fixed patterns".
Explanation:
Fixed action patterns are instinctive programmed responses in different species that are triggered by a specific external sensory stimulus. These stimuli are called <u>sign stimuli</u>. When the sign occurs, the animal starts a sequence of acts in response to the stimulus and continuous until the series of actions is completed. If the animal is interrupted for some reason, it continues its job from where it was interrupted; either the original stimulus is or is not present.
- A <u>chick’s gaping mouth</u> induces a feeding response in a parent bird: <em>The stimulus is the gaping mouth</em>, which <em>makes the parents</em> to instinctually respond f<em>oraging</em> more and <em>feeding</em> the chick.
- A male fruit fly <u>waves his wings</u> at a female fruit fly during courtship: In courtship, the <em>original stimulus is the presence of the female</em>. One of the <em>male´s responses actions is the wave of its wings</em>.
- A baby garter <u>snake captures and eats a slug</u>: For the baby snake, the <em>sign stimulus is the slug scent</em>. The snake then <em>responses</em> by <em>capturing and eating the slug</em>.
- A European <u>cuckoo hatchling pushes the host bird's egg</u> out of the nest: The <em>stimulus</em> for the cuckoo chick <em>is the presence of the host bird´s egg</em>. When the cuckoo bird emerges from its egg, even before it opens its eyes, it <em>pushes the host out of the nest.</em>
The respiratory system brings oxygen into the lungs when you breathe. The digestive system breaks food down into nutrients such as glucose. Now the circulatory system enters the picture. ... The circulatory system also transports carbon dioxide waste from the cells to the lungs of the respiratory system
