Answer:
Kartegener's disorder
Explanation:
The respiratory tract has cilia which move. Sperms also have a tail that moves. They both have the same protein in their structure called microtubules. There is a disorder in which there is the absence of a part in the microtubule. Dynein arms absent in microtubules. Because the respiratory system and sperm both contain cilia that's why these two systems have a connection and not work properly.
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.
I dont understand what is being asked
Answer: Amylose
Explanation: Which complex carbohydrate contains only a-1,4-glycosidic linkages? Amylose (Amylose is formed from a-1,4-glycosidic linkages of glucose.)
Answer:
The main difference is in the presence of a carbon atom; organic compounds will contain a carbon atom (and often a hydrogen atom, to form hydrocarbons), while almost all inorganic compounds do not contain either of those two atoms. Meanwhile, inorganic compounds include the salts, metals, and other elemental compounds.
