Answer:
Ptolemy included epicycles in his orbits.
Explanation:
Ptolomy's model of the solar system was geocentric, where the sun, moon, planets, and stars all orbit the earth in perfectly circular orbits. The problem with perfectly circular orbit around the Earth is that they do not explain the occasional backward motion, or retrograde motion, of the planets.
The Greeks insisted that the motion of the planets be perfectly circular. Ptolemy modeled the planets making small circles around a point that orbited the Earth. These smaller circles were called epicycles, and they allowed the planets to move backward relative to the background stars.
Answer:
The sequence of amino acids
Explanation:
The asters function in cell division is to separate the sister chromatid away from each other to process the Telophase
Answer:
Nucleus
:
Holds DNA and all the components of proteins.
All Eukaryotic cells have a nucleus and the rest of the membrane-bound organelles
Prokaryotic cells have no nucleus
Ribosomes
:
Take the amino acids and package them into protein chains.
Ribosomes are on the outside of the endoplasmic reticulum
Endoplasmic Reticulum
:
Organelle that transports the completed protein within the cell
Golgi Apparatus
Transports the completed protein from the ER to the outside of the cell. Vesicles carrying the proteins break off the Golgi apparatus moving the proteins outside of the cell
Plasma Membrane
Selectively permeable membrane that allows passage of many materials into and out of the cell.
Transport proteins on the surface help send out messenger proteins to other cells.
Explanation:
Once proteins leave the cell they will be received by another cell. In this way, cells are able to communicate with each other. All cells have protein receptors on them which recognize specific proteins.
Answer: 4 It will have a high tide because the greatest gravitational pull of the moon is experienced when the coastline is aligned with the sun and moon.
