The plant cell use the energy to maintain and establish a proton gradient.

The electrons flow through the elecron transport chain in the inner mitochondrial membrane producing a build-up of proton in the inner membrane space. This proton gradient is the direct source of energy for generating ATP.

object forms when a supergiant runs out of fuel?a red giant a black hole a white dwarf a neutron star
LenKa [72]

<u>ANSWER:</u>

When a supergiant runs out of fuel, the object formed is either a black hole or a neutron star.

<u>EXPLANATION:</u>

  • Supergiant are very large stars in the galaxy that end their lives very quickly.
  • When a supergiant star loses its fuel, it blows itself by a supernove explosion.
  • When supernove explosion happens, the supernova outshines other stars in the galaxy and then slowly faded away leaving a dense object called black hole or neutron star.
  • This black hole or neutron star is surrounded by a mass of very hot gas and the elements of the supergiant star get scattered into the space.

Restriction enzyme HinfI cleaves a five nucleotide DNA sequence GA(A/T)TC. The ambiguity in the central position - (A/T) - means
Afina-wow [57]

Answer:

C) 2.0 kb

Explanation:

It is given that out of the 4 nucleotides A, T, C & G each one has equal probability to occur at any position on the DNA molecule which simply means that the probability of occurrence of any nucleotide at a position is 1/4.

Also, it is given that probability of occurrence of either A or T at 3rd position is equal which means that the probability at that particular position will be 2/4 = 1/2.

Now, GA(A/T)TC is the DNA sequence where Restriction enzyme HinfI cleaves so the total probability of an average HinfI cleavage fragment will be = 1/4 x 1/4 x 1/2 x 1/4 x 1/4 = 0.00195 = 0.2 i.e. 2 kb.
