What happens when an electrical gradient and a chemical gradient are applying opposite forces to active transport?

Biology

Answer:

In a cell, there are two kinds of gradients found, that is, chemical and electrical. The electrical gradient is produced by the net charge of negative and positive charges found across the membrane. The chemical gradient is produced by the concentration of ions across the membrane. In combination, it is called the electrochemical gradient, which in general function in reverse directions.  

The procedure where pumping of ions takes place across the membrane via ion pumps against the electrochemical gradient is known as the active transport. This mode of transport sustains the balance of ions across the membranes and is dependent upon energy. The ATP is provided by the metabolic activities of the cell.

Mnenie [13.5K]

German roaches have flat bodies with six legs, two antennae projecting from their heads, and flat bodies, just like their American cousins and other cockroach species. Contrarily, American cockroaches are typically reddish-brown in appearance and develop to a length and width of around an inch and a half.

1. Why is the quadrat method useful for estimating snall populations? Explain why the same method would not be useful for counti
irga5000 [103]

Answer:

Quadrat method is used for estimating the number of individuals in an area. In this method, a large square area on the ground or water surface is marked, call it an enclave. The number of animals present in this enclave is counted. Then by assuming that the animals are less migratory and are uniformly distributed, their number for a large area is estimated by the use of unitary method of calculation. Example a 4 square feet area has 2 snails, then a 1000 square feet area will have (1000 x 2)/4, i.e, 500 snails in it. Fishes can be counted using this method only if they are confined in a small water body like a lake or a pond. Rivers are flowing so the fishes may move along its length which can give us an underestimate or an overestimate of their numbers. Sea has its depth and huge area, and fishes can be moving randomly in it. Hence this method will not work for river and sea fishes.

Hope this helps :D

What other recent hypotheses would corroborate the hypothesis that life on earth originated in space? (choose all that apply.)?
LuckyWell [14K]
The answer would be meteorites containing amino acids.  Most of the amino the amino acids revealed in the new investigation were not guaranteed up in proteins or polymers. Furthermore, the most plentiful amino acids originate in biology are those that are set up in proteins, but such "proteinogenic" amino acids signify only a small fraction of the amino acids originate in the meteorites.
