Answer: Higher concentration; Lower concentration.
Explanation: The food that we eat undergoes digestion and breaks down into smaller components.
These small components of the food needs to be absorbed first by the process of diffusion.
The water molecules along with the electrolytes are absorbed from an area of its higher concentration in the lumen is transported to area where its concentration is very low.
Hence, the correct answer is diffusion, which is responsible for the transportation of products from one place (higher concentration) to another parts (lower concentration)in the body.
Molecules are defined as the smallest particles of a chemical compound or an element, and are made up of atoms. Cells are made up of semi permiable membranes that only allow selected materials to move in or out of the cell, therefore due to the big size of molecules compared to atoms the membrane doesn't allow their passage in the cell. Therefore the cell doesn't allow most molecules to diffuse passively to the cell. Secondly, molecules that can enter the cell requires specific carriers carriers that will enable entry of small molecules in the cell.
Answer:
The correct answer would be B. thrombocytes.
Thrombocytes, also called platelets are the components of the blood which play important role in the process of hemostasis.
Hemostasis is the process of preventing the flow of blood from the damaged site or damaged blood vessel. It is the first stage involved in the healing of the wound.
Platelets form the platelet-plug at the site of damage which in turn activates another blood clotting factor fibrinogen.
Fibrinogen gets converted into an active fibrin (insoluble) which forms the meshwork like structure to trap more and more platelets and red blood cells. It results in the formation of a clot which completely seals the cut or damaged site.
No because they wouldnt be able to move on land to find food and i think they cant breath either
It goes from high to low. It is explained as it is trying to spread out or it is trying to be equal across a space.
