Let's hear it this way...

Manny Pacquiao lost a fight and people are blaming his change in religious out look for it. i just heard someone on the TV say that Pacquiao lost because he stopped wearing his rosary and doing the sign of the cross on his fights ever since his challenge with Bradley. well let me sort this out,.. by this, you guys are implying that wearing a rosary is and has always been his path way to victory. so, if wearing a rosary+sign of the cross=victory, and considering the fact that marquez and bradley eventually won, please ask this to yourselves ; did Bradley and Marquez wear a rosary on their victory?
Manny eventually fought as if his only goal was to erase people's disappointment to him due to his performance during his previous fight, particularly being slow enough to deliver less hits on Bradley. He fought hoping he would bring back the smile on people's face by showing that he regained his vast speed which people thought was already gone. He did it for the sake of everyone's entertainment and he did it in exchange for the fatal blow on his face.
Manny lost because he was meant to lose, the creator have probably decided a better plan for this event and of course Manny's life proves that he is being prepared for something better in life other than boxing.

Pacquiao, on the hands of defeat, still showed a positive outlook on his fight and
appreciated Marquez's drastic improvement in boxing skills.
his sportsmanship and attitude never failed to surprise many. this is what his new religious outlook made him.One heck of a boxer I still salute!

:-) Long Live Filipinos!

Online Assignment in Nat. Sci. 2 (BS ArchTech-1)

Hello Children...this will be your first online assignment in my subject..let me first assess how far have you gone in Biology as far as your knowledge is concerned...Your GUESS is welcome... Good Luck!! :)

1. Leafy sea dragons have leaf-like appendages that mimic the fronds of the sea kelp beds in which they inhabit.

b. adaptation
c. growth and development
d. maintenance of internal constancy

c. Male pheasants, painted a drab color, were ignored by the females during mating season.
d. In an experiment, it was found that male pheasants were attracted to the drab-colored female pheasants.
e. If female pheasants were more brightly colored, then they will be "sitting ducks," especially during the hunting season.

5. What are the two primary environmental factors determining the distribution of biomes in different regions of our planet?
a. latitude and elevation
b. temperature and precipitation
c. the tilt of the Earth and relative distance from the sun
d. global air circulation and ocean currents
e. El NiƱo and global warming

6. "Seasons" on the planet Mars are characterized by variation in the size of its polar ice cap and the severity of its dust storms over the course of the Martian year. What causes these "seasons" of Mars?
a. topographical differences, such as its great channels and tall volcanoes
b. gravitational forces from other bodies in the solar system
c. rising and falling air masses
d. its relative distance from the Sun at different times of the Martian year
e. the tilt of the planet and relative changes in the angle of incidence of sunlight

7. Why can many different species coexist in an ecosystem when they are competing for limited resources?
a. each species is found in a different biome
b. each species occurs in a slightly different habitat
c. each species occupies a different niche
d. each species comprises a different population
