Answer:
Repolarization
Explanation:
Complete repolarization is achieved by the sodium pump. This actively pumps all the Na+ ti the outside and all the K+ to the inside. The pump requires energy in the form of ATP and is inhibited by metabolic poisons. Entry of Na+ is immediately followed by an increase in the permeability of the membrane to K+. These diffuse rapidly to the outside due to the concentration gradient. Being positively charged, the K+ reverses the polarity of the membrane making the outside positive.
Answer:
1. D. Only DNA contains genetic information
2. D. Nitrogen and Phosphorus
Explanation:
1. Lipids are insoluble in water unlike other molecules. It stores energy within the fat tissues and cushion internal organs against trauma.
Carbohydrates are sugar units such as monosaccharides, disaccharides molecules which makes up starch that is fuel to your cells.
DNA is a type of nucleic acid that contains genetic information which influences your personal characteristics.
2. The family Rhopalodiaceae has the ability to perform nitrogen fixation, which allows diatoms to fix atmospheric nitrogen. And phosphorus has been found in some diatom species in the Black sea region which does not affect its reproduction rate and also helps in carbon cycle.
Answer: Here you go!
Explanation:
Doubling the amount of grass would definitely increase the rabbit population since there is more food/resources for it to produce. Since the food chain has a domino effect everything else would go up as well because of the increase of food/resources that will help sustain the population of all. so for the first line it would be increase for rabbit snake and hawk. Halving the amount of grass would effect the population of all animals as well. But in a more negative way. It would decrease because the rabbits wouldn't have enough food to produce and thrive. With the decline of rabbits less snakes will live because of the low amount of their main food source. Same with the eagles. So therefore it would be decrease in all the bottom lines.
