Biology

Zolol [24]3 years ago

Answer:

Gills are evaginations of the body surface. Some open directly to the environment; others, as in fishes, are enclosed in a cavity. In contrast, lungs represent invaginations of the body surface. Many invertebrates use gills as a major means of gas exchange; a few, such as the pulmonate land snail, use lungs.

Explanation:

They're just their to help the fish breath

Answer:

Basically, gills filter the water around the animal and take in the small amount of oxegen mixed in the water. Lungs take in all of the air and almost half of it is oxgen and they can't go underwater for long. But since lungs are more efficient, animals with lungs can grow bigger than animals with gills

Consider a cell in which Cl- distributes passively across the membrane according to the membrane potential. The resting membrane
UNO [17]

Answer:

1000 mM

Explanation:

Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM

So, V = -60 mV㏒₁₀[K/K']

-60  mV = -60 mV㏒₁₀[K/K']

dividing both sides by -60mV, we have

-60  mV/-60 mV = ㏒₁₀[K/K']

㏒₁₀[K/K'] = 1

taking antilogarithm of both sides, we have

[K/K']  = 10¹

multiplying both sides by K', we have

K = 10K'

K = 10 × 100 mM

K = 1000 mM

So, the intracellular Cl- concentration is 1000 mM
