Answer:
The correct answer would be D) tissue.
In biology, the level of organisation from simplest to complex level can be summarized as:
Organelles → cells → tissues → organs → organ systems → organisms → populations →communities → ecosystem → biosphere.
It is clear that tissue is organization level that exists between cells and organs.
When similar cells are assembled together to perform specific function, the assembly or this organization is said to be the tissue.
There can be different types of tissues such as muscle tissue, nerve tissue et cetera.
Similarly, tissues arrange themselves to carry out specific function in the form of organ.
For example, heart is made up of cardiac tissue.
The rate at which Tanya's turtle travels is 0.25mi/hr
This question is from a topic in mathematics called Rate.
<h3>Rate</h3>
This is a ratio in which different terms in different units are compared against each other.
In this question, for every 1/6 of an hour, the turtle is crawling 1/24 of mile.
Data given;
Let's express this mathematically

What this calculation shows is that the turtle travels at 0.25mi/hr
The rate at which the turtle travels is 0.25 miles in an hour or 0.25mi/hr

Answer:
Dinosaurs are the extinct organisms that belong to the class reptilia. Dinosaurs are the most advanced and bulkier reptiles at the history time and they were overspecialized in their environment.
The dinosaurs extinct rapidly due to the change in the external conditions and the volcanic eruptions that occur at the dinosaurs time. The recent searcher claims that asteroid impact and massive volcanic eruption leads to the dinosaur extinction. The fossil evidence and the presence of the specific basalt and other chemicals are found in the volcanoes and in the asteroid.
