The three primary mechanisms by which molecules move across the cell membrane are :
- Passive transport, the movement of molecules that does not require energy
- Diffusion,  when molecule move from higher concentration to lower concentration
- Osmosis, when molecule move to higher concentration

hope this helps

Contrast what happens to thermal energy in evaporation and condensation
Alex17521 [72]
Answer - Will try to Answer in simplest form with Reasoning. Since no one responded.

1.Solar-Thermal energy. For example the sun radiates thermal energy aka heat which then turns Liquid aka Water in gas molecules because they are escaping. (Evaporation) 

2. Condensation happens when the water molecule vapor clump together before thermal energy can be separated by it. Such as the clouds which they form tiny vapor/mist. Thats why when your on a plane and when you hit thru that cloud at hundreds of mph. Your hitting water molecules lol.

Answer:

All cells exhibit basic structural similarities. The general plan of cellular organization varies between different organisms, but despite these modifications, all cells resemble one another in certain fundamental ways. Match each description with a feature. separates contents of cell from surroundings made up of contains sugars, salts, and amino acids contains prokaryotic DNA contains eukaryotic DNA matrix?

1. Prokaryotic and eukaryotic cells both has a nucloid/nucleus, organelles, cell membrane, contains ribosomes, has cytoplasm

2. Nucleus; contains eukaryotic DNA

3; Nucloid; contains prokaryotic DNA

4; Cytoplasm; semi fluid matrix, contains sugars salt and amino acids

Explanation:

The cell from latin cella, meaning "small room" is the basic structural, functional and biological units of all known organisms. A cell is the smallest units of life and they are often called the building blocks of life the study of cell is called cytology. cells contains cytoplasm enclosed within a membrane which contains many biomolecules such as potein and nucleic acids. most plants and animal cells are only visible under a microscope with dimensions between 1 and 100 micrometers.
