Claudius Ptolemy is known to as a writer, mathematician, astronomer, geographer, astrologer. His hypothesis in regards to the solar system was that he used a mathematical model of the Almagest to represent the universe as a set of spheres. From there he created epicycles to calculate different dimensions in the solar system that he had created. For example, he calculated that the radius of the sun is about 20,000 times that of the earth.
In the other hand, Johannes Kepler was a German mathematician, astronomer, and astrologer. He believed that based on his religion the sun was the source of movement in the solar system. In addition, he believed that the sun caused a change in motion depending on how close a planet is to the sun.
I think it should be the lung.
Answer:
The correct answer is - each macromolecule has its own function and role in the body of an organism.
Explanation:
There are four major macromolecules that are essential for the energy and growth and development of an organism, are Proteins, carbohydrates, fat and nucleic acids. Each macromolecule is essential and found in various food sources so any specific macromolecule can not found in a healthy diet.
Proteins play various roles in the body such as support, building blocks, carriers, enzymes, and hormones. On other hand, carbohydrate provides energy for the cells, the transmission of the genetic information will be transferred by a nucleic acid. Fat also helps provide insulation, make lipid membranes.
According to the cladogram, Osteichthyes belong in group A.
Osteichthyes are a class of fish that have real bones and jaws as derived traits. These derived qualities can therefore be traced backwards from group A, with each line indicating a connection or relationship.
What is Cladogram?
- In cladistics, a cladogram is a diagram that is used to depict relationships between species.
- Cladograms reconstruct the taxa's evolutionary history (phylogeny) by showing these links. Phylogenies and trees are other names for cladograms.
- A cladogram's root, clades, and nodes are its most important components. The root is the first ancestor shared by all groups that branched off from it. The branches that represent related groups and their shared ancestors are known as clades. The points known as nodes represent the fictitious ancestors.

Most of us already know that darkness<span> is the absence of light, and that light travels at the fastest </span>speed<span>possible for a physical object. So, what does this mean? In short, it means that, the moment that light leaves, </span>darkness<span> returns. In this respect, </span>darkness<span> has the same </span>speed<span> as light</span>
