Answer:
The sternum, thoracic vertebrae, and ribs protect the heart and lungs.
Explanation:
The skeleton can be divided into the <em>axial skeleton</em> (the skull and the vertebral column), <em>visceral skeleton</em> (ribs and sternum) and the <em>appendicular skeleton</em> (extremities).
The function of the <em><u>visceral skeleton</u></em> is to <em>support and protect</em> the first portion of the digestive and cardio-breathing apparatus.
In mammals, the second part of the vertebral column (thoracic vertebrae), the ribs and the sternum delimitate a protective box for lungs and heart.
Answer:
The eukaryotic cell is 10 to 100 times larger than the prokaryotic cells.
Explanation:
The eukaryotic cell is 10 to 100 times larger than the prokaryotic cells. The prokaryotic cells are primitive, simpler in structure. The eukaryotic cells are complex in structure and have different adaptation for various cellular activities.
All the cells have cytoplasm, cell membrane, nucleus. In prokaryotes, the nucleus is not well defined and no other membrane-bound organelles.
e.g. bacteria, archaea.
The diameter of prokaryotic cells is smaller than the eukaryotic cells. Because the transport of ions and cell division is faster in it. Its diameter ranges from 0.1 micrometers to 5.0 micrometers. While eukaryotic cell diameter is 10 to 100 micrometers.
The small size of the prokaryotes is an advantage to its cellular processes whereas the eukaryotic cells are larger. Because it has to adapt to the function of different cell organelles present in it.
I believe the answer is D.
The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.
Hope this helps! Sorry if incorrect
The answer is 'sensory adaptation'. This happens when your sensory system senses a constant stimulus. After a short while, your sensory system will respond less, and then won't respond at all. This is to allow adaption to your environment. For example, if you live above a subway system, you will eventually become used to the sound of underground trains and vibration, and eventually you won't notice it at all..
