The cell is hypotonic, when the cell over-expands breaks.

The cell will be in a hypotonic condition.  

In this condition, where a cell is placed in a hypo tonic solution, the solvent outside the cell wall starts moving into the cell and the cell will swell. This will continue untill the turgor pressure stops  preventing influx and after this the cell will burst due to increase internal pressure.

Before replication can take place.(1) A. DNA polymerases must add complementary nucleotides to DNA. B. the two strands of DNA mu
andriy [413]

Answer:

The correct answer is B. the two strands of DNA must separate.

Explanation:

DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.

The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.  

After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.

Describe ONE similarity in the interaction between receptor: hormone , antibody: antigen, enzyme: substrate ? PLEASE HELP
nlexa [21]
All mentioned complexes (receptor-hormone, antibody-antigen, enzyme-substate) are involved in a molecular recognition.The molecular recognition involves <span>non-covalent </span> interaction between molecules. To form complex, molecules must be complementary in shape and charges, and usually, they are compared to key and lock. This way, the selectivity and specificity of recognition between molecules are assured.

GalinKa [24]

Answer:

It's an alarming situation about the decline of commercial fish population and we must need to develop the policy solution to this dangerous fisheries problem.

We can develop more fish by fish hatcheries to increase the population of fish and release large number of fish into the ocean.

We should give the awareness to the general public related to decrease the recreational fishing impact.

Commercial fishing must be ban until we reaches the sustainable level of fish.

There must be place international limits to every country related to limited number of fish they can take.
