What is the difference between plankton, nekton and benthos?

Biology

Archy [21]3 years ago

<span>The common difference between the three organisms is the area in which they specifically live or stay in the ocean. Planktons can’t be seen by the naked eye and they require microscopes to be detected. Planktons usually float in the water and they cannot move on their own that’s why they are dependent in the movement of the water.

Nektons are organisms that swim through the water and they live in different depths in the ocean ecosystem. Nektons are composed of fish and other mammals that propel themselves through the water.

Benthos are organisms that live in the ocean floor and many of these organisms stay in one place by attaching themselves to rocks. This adaptation protects them from crashing waves and drastic water movements. Other benthos are known to burrow in the ocean floor either for food or protection.</span>

Explain how human insulin can be produced using gene splicing.​
Margarita [4]

Answer:

The gene for human insulin is inserted into the gap in the plasmid. this is done through the use of restriction enzymes and ligase to insert and close the plasmid. This plasmid is now genetically modified. The genetically modified plasmid is introduced into a new bacteria or yeast cell. The more the cells divide, the more insulin is produced as bacteria divides into two identical daughter cells like in mitosis.

Anestetic [448]

Answer:

Codominance

Explanation:

Codominance occurs when two heterozygous allele for a trait is expressed equally in the an organism's phenotype with neither allele being dominant or recessive. In codominance, none of the allele hides the expression of the other allele. So when two alleles are crossed, the offspring carries a combination of the parents phenotype without anyone masking the other.

From the question,  the type of genetic pattern of the leopard geckos display is codominance.

Bacteria can make their own folic acid, which is required for nucleic acid synthesis, but humans cannot and instead have to inge
lidiya [134]

This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.

Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.

Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.

These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).
