What would happen if the sand dunes in an area were destroyed?
poizon [28]
There's a shrink to the upward thrust of a sand dune. they do no longer stay interior a similar place yet crawl downwind and are replaced by capacity of latest ones. at last, they attain the factor the place they'd be stabilized by capacity of plant existence. Barrier islands are formed a similar way, different than by capacity of water, somewhat than wind.

What are the advantages to using prokaryotic as host systems for genetic engineering? What are the limitations to genetic engine
ahrayia [7]

Answer and Explanation:

The manipulation of the gene is called genetic engineering. In genetic engineering, fragments of genes are cloned by leading the genes into the host cell. The advantage of using a prokaryotic host system in genetic engineering is that bacterial cells are used to produce commercially significant products. For example, human growth hormone helps to treat dwarfism, and human insulin production, which is used to treat diabetes. The bacterium P.putida is created by genetic engineering, which is used to break down petroleum products. Genetic engineering also carries some potential risks, such as transferring the selected gene into another speice, benefit one species can harm another speice. Therefore genetic engineering must be used in limit in prokaryotes. These limitations are also addressable in single-cell eukaryotic systems. Biologics-based therapeutic medicines such as a vaccine, gene therapies, and cell therapies known as bioproduction are produced. Medicines are so complex that they can only be formed in a living system. Biopharmaceuticals, value-added food, fuels, chemicals, antibiotics, and many other products are produced by bioproduction.

Which two processes does this diagram most directly models?
svet-max [94.6K]

The correct answer is D. Homeostasis and transport of molecules

Explanation:

The diagram presented shows the movement of glucose from outside the cell to inside it. Also, this diagram illustrates this process occurs through the cell membrane and there is a higher concentration outside the cell.

This complex process illustrates the transport of molecules in the cell, which refers to a mechanism that allows molecules and substances to move in and out of a cell. Moreover, this process implies molecules (in this case glucose) move to one area with a lower concentration to preserve equilibrium as shown by the diagram. Additionally, this equilibrium is part of homeostasis which is a set of mechanisms to main an equilibrium in the cell, including appropriate levels of glucose and other substances.
