What are some proposed disadvantages to utilizing DNA technology?
vfiekz [6]
Most of the downsides of recombinant DNA technology are ethical in nature. Some people feel that recombinant DNA technology goes against the laws of nature, or against their religious beliefs, due to how much control this technology gives humans over the most basic buildings blocks of life.

Other ethical concerns also exist. Some people worry that if companies can pay scientists to patent, buy and sell genetic material, then genetic material could become an expensive commodity. Such a system might lead to people having their genetic information stolen and used without permission. It may sound odd, but such cases have already happened. In 1951, a scientist used unique cells stolen from a woman named Henrietta Lacks to create an important cell line (the HeLa cell line) which is still used in medical research today. Her family did not know about her involuntary donation until after her death, and never received compensation, but others have profited from the use of HeLa cells.

Many people worry about the safety of modifying food and medicines using recombinant DNA technology. Although genetically modified foods seem safe in multiple studies, it is easy to see why such fears exist.
Hope this helps

2. The vasa recta is a specialized capillary that branches from the ___________ arteriole. The blood flow in the vasa recta runs
lorasvet [3.4K]
<h2>Vasa recta </h2>

Explanation:

The vasa recta is a specialized capillary that branches from the efferent arteriole; The blood flow in the vasa recta runs parallel, but in the opposite direction to the flow of tubular filtrate within the nephron loop

  • The vasa recta capillaries are long, hairpin-shaped blood vessels that run parallel to the loops of Henle
  • The hairpin turns slow the rate of blood flow, which helps maintain the osmotic gradient required for water reabsorption
  • Absorbed water is returned to the circulatory system via the vasa recta, which surrounds the tips of the loops of Henle
  • Because the blood flow through these capillaries is very slow, any solutes that are reabsorbed into the bloodstream have time to diffuse back into the interstitial fluid, which maintains the solute concentration gradient in the medulla; this passive process is known as counter-current exchange

andrey2020 [161]
The presented picture shows 4 trophic levels of the ecosystem.
The first level is made out of primary producers, plants. The second level is made out of herbivores that feed on the plants. The third level is made out of predators that eat herbivores.
The fourth trophic level is made out carnivores that eat other carnivores.
In our case, the only organism belonging to the fourth trophic level is the wolf.
