Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.
Answer:
The high yielding property of a plant species would be most useful for meeting the scientists’ goal.
Explanation:
In selective breeding, we develop a new variety by crossing a wild specie with the domestic growing variety in order to achieve the characteristic which is present only in wild specie. So with the help of selective breeding, this characteristics is transferred to the offspring. The main goal of scientist is to produce such variety which produces maximum yield and also good quality seeds.
Answer: Option C.
C)the tails of plant lipids cannot pack as tightly together as animal ones
Explanation:
The tails of plant lipids cannot pack as tightly together as animal ones because the double bond in plant lipids make the hydrocarbon chains to bend making them no to pack tightly together which cause a reduction in van der Waals interaction between the fatty acids. The length of the double bond also affect the melting point of fatty acids . If the hydrocarbon chain is long, melting point will be high .
