Spicules are structural elements found in most sponges. They provide structural support and deter predators. Large spicules that are visible to the naked eye are referred to as megascleres, while smaller, microscopic ones are termed microscleres.
I think it's made up of 2 or more of the <em>same type</em> of atom.
<u>Answer</u>:
In an ideal intercuspal position, the mesiofacial groove of a mandibular first molar opposes "A triangular ridge of the mesiofacial cusp" of the maxillary first molar
<u>Explanation</u>:
Triangular ridges are those which arises from the cusp guidelines of premolar and molars near the central groove. Transverse ridges are designed by the grouping of two triangular ridges on the posterior teeth. The connection of the buccal and lingual triangular ridges is frequently termed as an example. Being a non-functional cusp it is a mandibular tooth. The crown touches into lingually. The cusp has four cusp edges they are mesiobuccal, distobuccal, mesiolingual and distolingual. The buccal and lingual triangular edges will lead to the establishment of the transverse edge in the central groove part.
Answer:
<em>The correct option is D. Theory</em>
Explanation:
The scientific method of research begins with a question.
To answer this question, a hypothesis is made. A hypothesis can be described as a tentative statement which is testable.
To test the validity of a hypothesis, observations and experiments are made. Based on the results from the observations and experiments, results are drawn and conclusions are made.
A scientific theory is a wide description for a hypothesis which is well tested again and again by observations and experiments. However, with time a scientific theory might change if new researchers are made.
These are all types of cake.
