Each parent contributes one allele for this trait.
Answer:
Both facilitated diffusion and active transport are selective processes. Only selective molecules are allowed to cross the membrane. They utilize carrier proteins to move across the membrane.
Explanation:
Diffusion is the process by which molecules move across a membrane respective of the concentration gradient. The plasma membrane is a <em>selectively permeable membrane</em> which allows specific molecules to move across the concentration gradient.
Molecules migrate from a region of higher concentration to a lower concentration in case of diffusion. It can be classified into simple diffusion and facilitated diffusion. These are examples of <em>passive transport</em>.
In facilitated diffusion molecules move across the concentration gradient with the help of <em>carrier proteins or channel proteins</em>. The carrier proteins bind to the molecule which has to be transported and change conformation to allow it to cross the membrane. For example glucose molecule is carried across through <em>GLUT transporter</em>. <em>Channel proteins</em> open a channel inside the membrane and molecules get transported across the gradient.
Active transport carries molecules against the concentration gradient with the assist of energy. ATP hydrolysis is utilized to generate energy. As a result of active transport, the molecules are aggregated on one side of the membrane.
The material or substance on which an enzyme acts upon is known as the substrate, they are nothing but reacting molecules and or substances that are able to ultimately be converted to product substances. By the aid of biological enzymes, that lower the energy of activation needed for a chemical reaction to proceed.
<u>Explanation:</u>
Note, Telangana is known to be an area whose climate is usually semi-arid, that is, it is an area that is dry and receives some small amount of rain.
Thus, plants in the Telangana region would usually possess the following adaptive features;
- ability to survive under extreme heat
- growing longer roots than normal in other to find water in the soil
- efficient water conservation especially in their stems.
