Answer:
The correct answer is "the S layer may play a role in protecting cells from viruses and predatory bacteria found in nature but not in laboratory cultures".
Explanation:
The S-layer (surface layer) is a part of the cell's envelope comprised of of identical proteins or glycoproteins that could be found in archaes and some bacterias in nature. The function of the S-layer is unknown, however the fact that is only seen in nature suggest that it may play a role in protecting cells from viruses and predatory bacteria found in nature but not in laboratory cultures. It is likely that archaes and bacteria synthesize the S-layer when they recognize viruses and predatory bacteria in nature, the S-layer is not synthesized in laboratory cultures because these pathogens are not present.
<h2>e) option is correct </h2>
Explanation:
Traveler's diarrhea is an intestinal infection that occurs as a result of eating or drinking contaminated food or water, food handlers who do not wash their hands after they use the bathroom can transmit the infection to people who consume the contaminated food
Due to diarrhea, kidney don't work properly and level of urea increases in blood
Due to the low carbohydrate intake, ketosis occurs in which stored fat is metabolized which results in build up of acids called ketones
If the body starts to use energy sources other than carbohydrates then it means it is using the stored energy, gluconeogenesis fulfills glucose requirement of cell by synthesis of glucose from non carbohydrate material
To supply with energy lipid metabolism occurs, fatty acids are oxidized and energy in the form of ATP is produced
Answer:
The Sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
