Answer:
Vesicle
Explanation:
Vesicles are organelles which are found in cells and are involved during the process of exocytosis, endocytosis or movement of materials within the cell.
In the question , The leaves absorb the nutrients in the fertilizer and look healthy. If a cell is compared to a plant, the organelle which would help transport fertilizer from the soil to the leaf would most likely be the vesicles.
Resultant force = mass × acceleration, therefore acceleration = resultant force ÷ mass
Resultant force = 19 - 1.7 = 17.3 N
acceleration = 17.3÷2= 8.65 ms-2
Answer:
antibodies being produced to fight off a pathogen inside the body
Explanation:
Specific immune responses, also known as the adaptive immune system are ways the body fights against pathogens. The body is able to identify cells that are unique to it. When pathogens bearing an unknown identity enter the body, antibodies are released to attack the antigens on the surface of these pathogens.
The body usually develops this immunity after a previous attack by the pathogen. Lymphocytes known as the B and T cells are released by the immune system t engulf the pathogens.
