Answer:
We live in an era of unprecedented road and highway expansion — an era in which many of the world’s last tropical wildernesses, from the Amazon to Borneo to the Congo Basin, have been penetrated by roads. This surge in road building is being driven not only by national plans for infrastructure expansion, but by industrial timber, oil, gas, and mineral projects in the tropics.
Few areas are unaffected. Brazil is currently building 7,500 kilometers of new paved highways that crisscross the Amazon basin. Three major new highways are cutting across the towering Andes mountains, providing a direct link for timber and agricultural exports from the Amazon to resource-hungry Pacific Rim nations, such as China. And in the Congo basin, a recent satellite study found a burgeoning network of more than 50,000 kilometers of new logging roads. These are but a small sample of the vast number of new tropical roads, which inevitably open up previously intact tropical forests to a host of extractive and economic activities.
Explanation:
The answer is a because that’s the right one
Answer: This is an opinion question so I will give you the facts so you can form your own opinion for this answer.
Explanation:
<u>PRO GMO:</u>
Manufacturers use genetic modification to give foods desirable traits. For example, they have designed two new varieties of apple that turn less brown when cut or bruised.
The reasoning usually involves making crops more resistant to diseases as they grow. Manufacturers also engineer produce to be more nutritious or tolerant of herbicides.
Crop protection is the main rationale behind this type of genetic modification. Plants that are more resistant to diseases spread by insects or viruses result in higher yields for farmers and a more attractive product.
Genetically modification can also increase nutritional value or enhance flavor.
All of these factors contribute to lower costs for the consumer. They can also ensure that more people have access to quality food.
<u>CONS of GMO</u>
Because genetically engineering foods is a relatively new practice, little is known about the long-term effects and safety.
There are many purported downsides, but the evidence varies, and the main health issues associated with GMO foods are hotly debated. Research is ongoing.
Some of the cons include: Allergies, Cancer, antibacterial resistance, and outcrossing which refers to the risk of genes from certain GMO plants mixing with those of conventional crops.
Answer:
RFLP analysis.
Explanation:
RFLP (Restriction fragment length polymorphism ) may be defined as a molecular technique used to determine the location of a particular gene in the DNA sequences. The individuals among the population can be easily identified by RFLP analysis.
The restriction enzyme is used for the digestion of DNA sample. The restriction fragments are then visualized by running the fragments on gel electrophoresis. The hybridization between single stranded nucleic acid is not involved in the RFLP.
Thus, the correct answer is option (1).
Electrolyte imbalance can affect the normal function of the brain. Sodium is an important electrolyte maintains homeostasis in the body. Its primary function is to regulate water retention. Low sodium usually decreases serum osmolality. This combination of deficiencies is called Hypotonic hyponatremia.
A sudden drop in sodium and plasma osmolality can cause seizures. Brain function is affected because the water in the body, because start to flow from the extracellular spaces into the intercellular spaces. This causes the brain cells to swell and thus affecting its normal function.
Therapy for this type is IV therapy, particularly hypertonic saline to replace the sodium in the body and normalize plasma osmolality and diuretics are given to aid in water excretion. Therapy should be done slowly and should be closely monitored. More swelling can developed when it is done too quickly.
