The Energetics of Coupled Transport
andrezito [222]

Answer:

Explanation:

A. False - A symporter system requires that one of the molecules to be transported using passive transport.

B. True - The Na+ will move down the established concentration gradient releasing energy to facilitate movement of sucrose against its concentration gradient. This is known as secondary active transport.

C.  False -  sucrose moves through ion channels not by diffusion to better control its movement across the membrane.

D. True - Movement of molecules against their concentration gradient thus requiring energy input is known as active transport.

E. False - One of the molecules needs to be moving against its concentration gradient.

F. False - A Uniporter system allows the binding and transport of a single molecule at a time. A symporter allows simultaneous binding and transport of Na+ and sucrose molecules.

1. Which blood types are dominant?
marishachu [46]

Answer: 1). A and B are both dominant (because A and B are codominant to one another)

2). E. All of the above

Explanation:

1). From the image above, A and B are both dominant because they are equally expressed when they occur in a pair (when they occur as blood type AB), also they are dominant because each of them expressed itself when it occurs in a pair with a recessive allele (IAi and IBi).

2). The children of a father with A blood and a mother with B blood will have all the four blood types: A, B, AB, and O. If each parent has a recessive allele, that is if each parent is heterozygous for his/her blood type (IAi for the father and IBi for the mother), the cross between them will produce all the four possible blood types.

See the attached punnet square for more information.

Suppose that a portion of double-stranded DNA in the middle of a large gene is being transcribed by an RNA polymerase. As the po
babunello [35]

<u>Answer:</u>

CCGAGU

<u>Explanation:</u>

DNA transcription:

DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.

During transcription two strands of DNA are named differently i.e Template strand and coding strand.

Template strand:

Strand from which RNA is producing is known as template strand while

Coding strand:

The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.

Correct Answer:

Template strand from 5' to 3' reads GGCTCA. and

In this question CCGAGT is coding strand.

RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes
