Scientists have debated the evolution of three life forms: reptiles, birds and dinosaurs. After many years of reviewing fossil r

ecords scientists proposed the evolutionary relationship seen above in the cladogram. Using radiometric dating scientists added a time frame for the evolution of the animals within the model.

Answer:

Turtles were the first group of animals to branch off in this tree of animals.

Explanation:

Turtles were the first group of animals to branch off in this tree of animals. According to the tree, the animals share a common ancestor. The first branch shows that what we call a speciation event occurred, resulting in two lineages. The first group of animals to result were the turtles. All the other animals are on the other branch. This does not indicate that any group is more highly evolved than the other.

Answer:

Question 1

D

Question 2

C

Question 3

D

Explanation:

1. An ecosystem is MOST likely to return to its original condition after Tall prairie grass burns after being struck by lightning.

Here is a research paper in which they explained how this happened. (Komarek, E. V. (1971). Lightning and fire ecology in Africa. In Tall Timbers Fire Ecology Conference (Vol. 11, pp. 473-509).)

2. In some national parks, controlled fires are maintained by firefighters. The major reasons for using controlled burns to maintain certain ecosystems is to give nonnative plants a chance to colonize the region.

A recent article provided the insight of this situation (Xanthopoulos, G., Delogu, G. M., Leone, V., Correia, F. J., & Magalhães, C. G. (2020). Firefighting approaches and extreme wildfires. In Extreme Wildfire Events and Disasters (pp. 117-132). Elsevier.)

3. One reason for the change in the Galápagos ecosystem has been the introduction of species that were not on the island before, such as donkeys, goats, cats, dogs, and insects. The introduction of nonnative species MOST likely disrupt the balance of life on the islands due to greater competition for limited food sources.

Scientist said that food competition is actually a struggle to survive in any ecosystem here is the reference paper (Eckhardt, R. C. (1972). Introduced plants and animals in the Galapagos Islands. Bioscience, 22(10), 585-590.)

Receptors that are especially important for helping a person maintain balance are located in the (A) gyrus cinguli (B) inner ear
Lera25 [3.4K]

The receptors that aid in allowing a person to maintain balance are located within the inner ear.

The human ability to walk upright without falling, and a wide variety of other tasks that we perform as all thanks to our ability to maintain balance. This ability is given to us by structures located deep within the inner ear.

The inner ear is located deep within the lateral side of the head. This ear contains 3 semicircular canals or ducts, which are tiny structures filled with liquid. Each of these canals has an expansion at its end known as the ampulla, which holds within it the very small cellular balance receptors called crista.
