Answer:
Passive Transport , Diffusion, Osmosis
Explanation:
Active Transport requires energy. Endocytosis, exocytosis and facilitated diffusion are types of Active Transport.
Passive Transport does not require energy. Diffusion and osmosis are types of Passive Transport.
Answer:
a. are acid participants in, or by-products of, cellular metabolism
Explanation:
cellular metabolism is the process in which several chemical recation stakes place in body. there aretwo type of cellular metabolism - catabolism and anabolsim, which serves for several body functions.
During the chemical reaction of cellular metabolism, many acids are produced which are called metabolic acids. Several metabolic pathways produces different acids such as carboxylic acid, citric acid and amino acid. All the metabolic acid maintains body's functional activities,if any case acid formation increases it causes metabloic acidosis.
Hence, the correct option is a. "Metabolic acids are the acid participants of celular metablosim".
1) The answer is <span>bluegreen algae
</span>
Bluegreen algae or cyanobacteria <span>are thought to have started life on earth because they converted the atmosphere that didn't have a lot of oxygen, into an atosphere with enough oxygen to exist life. That </span>oxygen was a product of their photosynthesis.
2) The answer is lightning.
<span>By Primordial Soup Theory, life began as a result of the combination of chemicals from the atmosphere and lighning (a form of energy) to make amino acids. Aminoacids are necessary to build proteins, and proteins are necessary for all the organisms.</span>
