Your sex given at birth is a major factor that can determine your growth
Selective permeable means it selects what goes out and comes into the cell. If the cell membrane wasnt selective then things could enter the cell and destroy it.
-Seth
Answer:
The correct answer is - Physics
Explanation:
Physics is the branch of science that is an organized study of matter, motion, light, energy, and its behavior in time and space. All these states in the observable universe and their effect is studied in detail in physics.
Physics is one of the basic and fundamental disciplines of science like biology, chemistry. Many other streams or filed of science are based on physics such as chemistry, oceanography, seismology, and astronomy.
Thus, the correct answer is - Physics
A transport system that moves one solute into the cell and another one out of the cell during a single cycle accompanied by the expenditure of energy through ATP hydrolysis could be called a(n) active transport.
<h3><u>
Explanation:</u></h3>
A system of transport that helps in the movement of one solute in a cell and the other out of the cell with a release of energy through ATP hydrolysis is an active transport. Active transport refers to the process that facilitates the molecules or ions to move across a cell membrane. This process requires enzymes and energy.
The movement of the ions or molecules inside a cell or out of the cell occurs across they cell membrane from the lower concentration region to the higher concentration region is the active transport process. It is always related to the accumulation process of ions, amino acids glucose which are higher concentration molecules.

Explanation:
Microtubules are polymers of tubulin and they are part of the cytoskeleton. The roles of the microtubules are to maintain the shape and structure of the cell, intracellular transport, they are structural part of the cilia an flagella, they are involved in cell division etc.
Tubulin that is the basic unit of microtubules is composed of two globular proteins, alpha and beta tubulin. Alpha and beta subunits spontaneously form dimers which then assemble into oligomers, then in chains (protofilaments); that can form a variety of intermediate structures such as single and double rings or spirals. Protofilaments that associate side-by-side form sheets of protofilaments which then curle to form a tube or cylinder (closing of microtubule). Continued growth of microtubules occurs by the direct addition of more dimers on + side.
