In salt water fish, chloride cells in the gills: a. actively transport Cl- from the plasma to the ECF. b. actively transport Cl-
lord [1]

Answer:

b. actively transport Cl- from the ECF to the external environment.

Explanation:

Chloride cells are cells that are found in the gills of teleost fishes which pump large amount of sodium and chloride ions out from the extracellular fluid (ECF) into the sea or environment against a concentration gradient in marine fish.

The opposite of this process occurs in freshwater fishes where the gills of freshwater teleost fish, cause an influx of sodium and chloride ions into the fish from the environment, also against a concentration gradient.

Mechanism of action

Salt water teleost fishes take in large amounts of seawater to decrease osmotic dehydration. The excess of ions derived from seawater is thrown out of the teleost fishes through the chloride cells. These cells employs active transport on the basolateral (internal) surface to diffuse in chloride, which then is pumped out of the apical (external) surface, straight into the surrounding environment. Such mitochondria-rich cells are located in the region of the gill lamellae and filaments of teleost fish.

A biochemist isolated and purified molecules needed for dna replication. Whne she added some dna, replictation occursd but the d
liberstina [14]

Answer:

She left Ligase enzyme out of the mixture.

Explanation:

DNA replication is the process of formation of new molecules of DNA from the existing one. This process occurs in semiconservative way i.e each new strand consist of one newly synthesised strand and one old parent strand that act as template for the formation of new strand. replication on one strand occurs continuously from 5 prime to 3 prime but on other strands it occurs discontinuously from 5 prime to 3 prime because DNA polymerase moves only in one direction from 5 prime to 3 prime. Hence in discontinuous strands gaps remained. These gaps are filled by Ligase enzyme.

Requirements for DNA replication:

DNA replications needs

Primers

DNA Polymerase enzyme

DNA helicase enzyme

Single nucleotide binding protein

dNTPs

and Ligase enzyme.

Correct choice:

She left Ligase enzyme out of the mixture.
