11 year solar cycle |
About every 11 years, the sun goes through a period where it emits more energy than normal through solar flares and electromagnetic storms. What do you call to this activity? |
|
|
Precession of the Equinoxes/Wobble |
One of Milankovitch cycle in which it refers to the changes in the Earth's wobble or changes in the position of the earth in it's orbit around the sun are the moment of the equinoxes and solstices. |
|
|
Ecosystem services |
Biodiversity and ecosystems produce a rich array of benefits that people depend on, including fisheries, drinking water, fertile soils for growing crops, climate regulation, inspiration, and aesthetic and cultural values. These benefits are called? |
|
|
Renewable Energy Resources |
These are energy resources that can reproduce themselves in nature over relatively short period of time and can be harvested continuously through a sustained proper planning and management. |
|
|
El Niño |
It is a large scale oceanographic/meteorological phenomenon that develops in the Pacific Ocean, and is associated with extreme climate variability i.e., devastating rains, winds, drought, etc. |
|
|
Possible Answers: -Greenhouse gases -Deforestation -Coal mining -Industrial Processes -Hydrofluorocarbons -Burning of fossil fuels -Carbon dioxide -Methane -Water Vapor -Nitrous Oxide |
Give atleast 5 anthropogenic causes of climate change.
|
|
|
Possible Answers: * It occurs int he Pacific Basin every 2 to 9 yrs * Usually starts during Northern winter (dec to feb) * Once established,it lasts until the first half of the ff yr, although at time, it stays longer (1939-1941 and 1989 -1992) * It exhibits phase-locking at annual cycles (El Nino and rainfall fluctuations with it tend to recur at the same time of the yr) * Usually has a biennial cycle (El nino will be preceded by La nina) |
Give one characteristic of El Nino
|
|
|
Temperature Trend |
It is the average rate of increase or decrease at the grid point over the time period of interest. |
|
|
Global Warming |
It is the slow increase in the average temperature of the earth's atmosphere because an increased amount of the energy ( heat ) striking the earth from the sun is being trapped in the atmosphere and not radiated out into space. |
|
|
Possible Answers: -Volcanic Eruption -Ocean Currents -Solar Radiation -Earth's orbital changes *Eccentricity *Obliquity *Precession |
Give atleast 3 natural causes of climate change.
|
|
|
Genetic modification is deliberately altering an organisms genome while hybrid undergoes cross-pollination of two different plant varieties. |
What is the difference between genetically modified organisms and hybrids? |
|
|
BT Corn |
What is the first genetically modified crop in the Philippines? |
|
|
Genetic Engineering |
It is also called recombinant DNA technology, a process that alters the genetic structure of an organism by either removing or introducing DNA. |
|
|
Paul Berg |
He is the Father of Genetic Engineering. |
|
|
Gene Therapy |
It is the modification of an organism’s gene. |
|
|
Stem Cells |
It provides the patient with a therapeutic technique that potentially lasts for a lifetime because of its ability to self-renew and to mature into specialized cells of each tissue. |
|
|
Cell Potency |
It is the cell’s capability to differentiate into various cell types. |
|
|
Extrinsic |
It is the issues connected to the application of genetic engineering. |
|
|
Insect Resistant |
One of the characteristics of a genetically modified crop that either naturally or through genetic engineering are able to resist insect damage. |
|
|
In Vivo |
Latin meaning “within the living,” administering the gene therapy inside the body of the patient. |
