Cyanobacteria, also known as blue-green algae, are found in vast quantities in fresh and salt water. Cyanobacteria are able to conduct photosynthesis. By utilising energy from the sun, they produce carbohydrates from water and carbon dioxide. As a byproduct, they produce oxygen. So cyanobacteria provided oxygen to the atmosphere that allowed other lifeforms to develop.
Endocytosis and exocytosis are similar in that they are both forms of cell transport. They differ because in endocytosis, a cell transports molecules into a cell (think: endo - in), and in exocytosis, the cell's molecules are transported by being expelled.
Answer:
Explanation:
Polarity of amino acids affects how they interacts. Amino acids such as valine, methionine, and alanine are nonpolar while serine, threonine, and cysteine are polar which mean they are hydrophilic this determines how the react.
The structure and the shape of amino acid also determines how they react.
The bond form between amino acids also affects its interaction
Answer:
The cell has to undergo a process called Osmosis
<span>The myelin sheath allows nerve impulses to propagate very quickly along a nerve's axon to transport the signal between nerve cells. The myelin coating allows the chain reaction of impulses to jump certain distances instead of waiting for the chemical changes to happen at all points on the axon.</span>
