The answer is D. Chordata.

There are three domains of life - Archaea, Bacteria, and Eukarya. All organisms that belong to the domains Archaea or Bacteria have cell walls. In the domain Eukarya, there are some groups that have cell walls and others that do not.

Chordata is phylum of the kingdom Animalia which belongs to the domain Eukarya. So, Chordata cannot be a domain.

Which of the following is an example of an adaptation that allows similar species to live in the same environment?
Andrei [34K]

Answer:

B. Both mussels and barnacles live in the tidal ecosystems.

Explanation:

Mussels are <u>small bivalve molluscs that are adapted to both marine and freshwater ecosystems</u>. Barnacles, on the other hand, <u>are arthropods that are adapted to marine ecosystems. However, both are adapted to shallow and </u><u>tidal</u><u> zones</u>.

Both organisms are small and have the capacity to live in tidal ecosystems where they thrive and play important ecological roles. For instance, barnacles are filtering organisms, which is extremely important for the food chain, and mussels filter out significant amounts of excess nutrients and metals, that is, they make the water more suitable and clean for organisms to live.

As they are both adapted to tidal ecosystems, this would be an example of an adaptation that allows similar species, in this case mussels and barnacles, to live in the same environment.

The interdependence of body systems is essential because
Zinaida [17]
The answer is letter C.
<span>
The interdependence of body systems is essential because all systems work together to maintain homeostasis. Homeostasis in body systems refers the regulation of internal conditions keeping it stable and relatively constant. In humans this refers to its ability to maintain stability in its internal environment while responding to changes in external conditions. It serves as a sensor that detects changes in the conditions that need to be regulated to meet the demands of the condition and give the necessary feedback. Regulation of body temperature and the balance between acidity and alkalinity are examples of homeostasis in the human body.</span>

Cells in humans use energy from what?
vladimir1956 [14]
The liver primarily uses fatty acid oxidation for energy. Muscle cells use fatty acids, glucose, and amino acids as energy sources. Most cells use glucose for ATP synthesis, but there are other fuel molecules equally important for maintaining the body's equilibrium or homeostasis.
