Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
Active transport uses ATP and does not require a carrier protein; facilitated diffusion does neither.
Facilitated diffusion uses ATP and requires a carrier protein; active transport does not.
Answer:
Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
Explanation:
Active transports moves against the concentration gradient (hence why it needs energy or ATP to do so, its going "against the grain"). Facilitated diffusion does not require ATP but does something require carrier proteins during passive transport.
Halley — the traditional pronunciation of the name usually rhymes with valley — was born Nov. 8, 1656, in Haggerston, Shoreditch, London, England. His father was a prosperous soapmaker and property owner. Halley was tutored privately at home before entering St. Paul's School, where he excelled in mathematics and astronomy.
Halley entered Queen's College, Oxford, in 1673, when he was 17 years old. He brought with him a fine collection of astronomical instruments purchased by his father. While still an undergrad, he became a protégée of John Flamsteed, the Astronomer Royal. Halley made important observations at Oxford, including an occultation of Mars by the moon, and published papers on the solar system and on suns
The statement that the testing for the Alu elements on chromosome 9 or 11 can be utilized by an individual for a paternity test is true.
It should be noted that testing for the Alu elements on chromosome 9 or 11 canbe used as a simple paternity test. This is because they're transposable elements that can act as markers.
Also, the polymorphism in it can be used for the paternity test. The genotype of an Alu element can be determined based on the width and the intensity upon which it's compared. When there's an insertion, there'll be an increase in the intensity of the band.

Plants use their leaves to capture light energy during photosynthesis, water and carbon dioxide are converted by plants into sugar, hence option a is correct.
Plants use glucose as a source of energy and to create other compounds like cellulose and starch and cell walls are constructed using cellulose.
In a process known as photosynthesis, plants use carbon dioxide, water, and sunshine to create sugar and oxygen.
Chloroplasts, tiny compartments found inside plant cells, are where photosynthesis takes place.
Therefore, the removal of carbon dioxide from the atmosphere and utilize water in the production of food make this a significant process for the planet, hence option a is correct.
