What is a list of some of the disadvantages of genetic engineering?

The main disadvantage of genetic engineering is the risk it poses to health. Some detractors claim that genetically engineered crops are inherently unsafe, but this can't really be verified because much of the data on health impacts is controlled by the genetic engineering industry. What scientists do know is that health hazards are present. In 1996 in Brazil, and in 1990 in America, there were documented cases of engineered food causing allergic reactions, the passing of diseases and even death.\nAnother disadvantage to genetic engineering is the problems it causes the environment. Engin..

What types of artificial satellites has India launched into space?

The agency that officially oversees India's space program is the Indian Space Research Organization, a project of the government's Department of Space. Since its inception, ISRO has launched more than 70 artificial satellites. These man-made objects have a variety of applications, including weather forecasting, news gathering, television signal transmission, global positional charting, Earth imaging, remote sensing, payload development and recovery technology. In 2014, India became the fourth nation to successfully launch a satellite into Mars orbit with Mangalyaan.

How do you use an L-square ruler?

An L-square (or tailor’s square) is a two-armed ruler used to make reduced scale patterns in pattern drafting. It eliminates the need for math when figuring scale measurements. The short arm has halves, 4ths, 8ths and 16ths. The long arm has two-thirds, 3rds, 6ths and 12ths. The tailor first determines which scale to use, then draws a line from the zero point at the corner of the ruler to the number on the desired scale corresponding to the original full-scale measurement. For example, if the full scale pattern calls for a measurement of 16 inches and the tailor wants to make a half scale pa..

What is Jupiter's atmosphere made up of?

Jupiter's diameter at the equator is approximately 89,000 miles. Clouds cover Jupiter's surface, and a prominent feature is the Great Red Spot, which is a massive hurricane-like storm. This storm has lasted about 350 years. Jupiter has strong winds that are between 192 to 400 miles per hour. It has a very strong magnetic field.The temperature on Jupiter is about -108 degrees Celsius. It takes Jupiter 11.8 Earth years to rotate about the sun. It has a fast rotation about its axis. Jupiter has three known rings and over 60 moons or satellites. Some moons are Io, Europa and Ganymede. Wi..

When did the first tree appear on Earth?

This tree species was among the first to be able to deliver nutrients and water to its leaves and roots. Scientists believe that the litter from this tree was a major contributing factor to the emergence of freshwater fish species that would go on to influence sea life. As many as 90 percent of forests were home to this species, although other trees would arise and then go extinct during the period in which the tree thrived.

What causes ice storms?

Ice storms form when a layer of warmer air becomes sandwiched between two layers of cold air. Snow or hail falls from the top cold layer, then it melts when it hits the middle warmer layer of air. As the precipitation hits the bottom colder layer, it refreezes. However, because of its journey through the warmer layer, the precipitation does not become snow again. Instead, it becomes freezing rain.\nIce storms are very dangerous because of the slick roads they create. Because ice is heavy, accumulations of ice can weigh down power lines, often causing severe power outages. An ice accumulation o..

What is the importance of gram staining in microbiology?

Gram staining requires a sample, which can be blood, sputum or mucus, states Healthline. The process of identifying bacteria in the sample involves using different agents, such as crystal violet dye, iodine mordant, decolorant and safranin. After staining, bacteria differentiation is possible because gram-positive bacteria have a purple color while gram-negative bacteria have a pink color when viewed under a light microscope. A basic difference between these two types of bacteria is their cell walls.

How does the digestive system of a cnidaria work?

The smell of fluids from the wounded prey causes the tentacles in cnidarians to fold inward toward the opening of the digestive cavity where the prey is deposited. When the food enters the gastrovascular cavity, glands release enzymes that turn the prey to slurry within a few hours depending on the size. The slurry circulates through the digestive cavity as gastroderm cells on the inner walls absorb the nutrients. Absorption takes a few more hours, and it takes a few days for the cells to fully process the nutrients. The circulation of nutrients is propelled by currents created by cilia in the..

What does 100 degrees Celsius equal in Fahrenheit degrees?

Converting between different temperature scales is important when performing certain calculations in subjects such as physics and chemistry. Although there are online temperature conversion calculators that can give this information, it is often necessary for students to learn how to use a formula to make a manual calculation.The formula used to convert from Celsius to Fahrenheit degrees is F = 9/5(C) + 32, where F stands for Fahrenheit and C is Celsius. To convert from Fahrenheit to Celsius, the formula is C = 5/9(F - 32). In addition to the Celsius and Fahrenheit temperature scales, the Kelv..

What are the different types of roots?

A plant's primary root is the first root that grows directly from the stem of the plant. The branches of this root are secondary roots, and the branches of the secondary roots are tertiary roots. If these roots are more or less the same size, the plant is considered to have a fibrous root system. Taproots are primary roots that are much bigger than the other branches. Adventitious roots may or may not penetrate the soil. Examples are the banyan tree, which has many prop roots, and epiphytes, which have aerial roots.
