- Question
Which statement fits the Frontier Ethic?
Options- A. Recycle plastic
- B. Help those in need
- C. He who has more toys wins
- D. Walk lightly on Earth
- Correct Answer
- He who has more toys wins
ExplanationFrontier Ethic is Spending Earth's assets at the cost of losing resource capital. A frontier ethic assumes that the earth has an unlimited supply of resources. It is the notion of disregarding the Earth for the benefit or gain of man.
If resources run out in one area, more can be found elsewhere or alternatively human ingenuity will find substitutes. This attitude sees humans as masters who manage the planet. It is completely Anthropocentric.

Correct Answer: Matter
Explanation:
Anything that has Mass and takes up Space is called Matter.
Matter has some mass and occupies some space. Mass means the amount of matter in an object. Space occupied by an object is called its Volume.
The Study of Matter and and how matter changes is called Chemistry.
Correct Answer: Distillation
Explanation:
The first step in the refining of petroleum is distillation i.e, the fractionation of crude oil in atmospheric and vacuum distillation towers.
The first process petroleum refinery is known as distillation. In this process, crude oil is heated and fed into a distillation column. As the temperature of the crude oil in the distillation column rises, the crude oil separates itself into different components, called "fractions." The fractions are then captured separately. Each fraction corresponds to a different type of petroleum product, depending on the temperature at which that fraction boils off the crude oil mixture.
Correct Answer: O
Correct Answer: An ozone molecule contains one single bond and one double bond
Explanation:
Ozone molecule has one single bond and one double bond.
Correct Answer: AB
Explanation:
In transfusions of packed red blood cells, individuals with type O Rh D negative blood are often called universal donors. Those with type AB Rh D positive blood are called universal recipients.
The immune system of a person with AB blood will accept blood from all possible donors, whether they have O, A, B, or AB blood. Since both A and B antigens are present in a person with AB blood, the recipient won't reject the blood. The body identifies that blood as "self" rather than "foreign."
Correct Answer: The Study of Blood is called as Hematology which involves treating diseases that affect the production of blood and its components, such as bloodcells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation
Correct Answer: Rich in Beta-Carotene
Explanation:
Golden Rice (Oryza sativa) denotes a genetically modified rice capable of biosynthesizing and accumulating ?-carotene (provitamin A) in the endosperm, yielding a characteristic yellow color in the polished grains. Golden rice was developed to help cope with vitamin A deficiency, a problem that prevails in developing countries, affecting millions (Underwood, 2000; UNICEF, 2000). Vitamin A deficiency causes mortality and growth retardation in children and frequently impairs vision, leading to blindness. It also contributes indirectly to anemia by interfering with iron bioavailability.
The endosperm of Golden Rice (Oryza sativa) is yellow due to the accumulation of ?-carotene (provitamin A) and xanthophylls. The product of the two carotenoid biosynthesis transgenes used in Golden Rice results in Pale Yellow color.
Correct Answer: 1901
Correct Answer: Anemophily
Explanation:
Pollination by wind is called Anemophily or Wind pollination. The process of the transfer of pollen from one individual plant to another, whereby the pollen is carried by air currents is called Anemophily.
Almost all gymnosperms (Non-flowering plants) are anemophilous, as are many plants in the order Poales, including grasses, sedges and rushes.
