Answer:
K+-coupled.
Explanation:
The transport of the solutes may occur along the concentration gradient or against the concentration gradient. Two main types of transport that occur in living organism are active process and passive process.
The passive transport do not require the energy for its transport whereas the active transport require energy. The K+ coupled transport do not require any energy molecule for its transport and easily transfer by the leaky channel. Hence, the K+-coupled transport is not the common active transport.
Thus, the correct answer is option (C).
Hi there! I hope I'm not late. The answer is D and E. I just got it right. Hope this helps ;)
The Y chromosome likely contains 70 to 200 genes that provide instructions for making proteins. Because only males have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and development.
<h3>What is a chromosome?</h3>
A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule. These chromosomes exhibit a complicated three-dimensional structure that is crucial for controlling transcription.
Under a light microscope, chromosomes are typically only discernible during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form).
Prior to this, each chromosome undergoes a process known as chromosome duplication (S phase), during which a centromere connects both copies, forming either the X-shaped structure (if the centromere is situated equatorially) or a two-arm structure (if it is situated distally) depending on where it is situated.

Formamide molecules are added to an electrophoresis buffer for the purpose of denaturing DNA.
<h3>What is the purpose of the buffer during electrophoresis?</h3>
A laboratory procedure called electrophoresis is used to divide DNA, RNA, or protein molecules according to their size and electrical charge. The molecules are moved by an electric current through a gel or other matrix. In the case of Denaturing Gradient Gel Electrophoresis (DGGE), the gradient can be an electrical field or a denaturant such as a solution of urea and formamide.
Size, charge, and other characteristics are used in electrophoresis to separate macromolecules like protein and nucleic acids. Scientists utilize buffer to transport the charge through the gel for electrophoresis that separates by charge. Additionally, the buffer keeps the gel's pH steady, reducing alterations that would take place in the protein or nucleic acid if the pH were to become unstable.
