No I have not completed it but, I'd be happy to help you with any other questions you might have.
Water, sunlight, and carbon dioxide
The P wave of the electrocardiogram is considered as a signal from the DEPOLARIZATION of the atria in the heart. This depolarization drives the contraction of the atrial musculature.
An electrocardiogram (ECG) is a device that records the electrical activity of the heart. This record can then be used to diagnose different heart conditions.
The P waves occur when the sinoatrial node generates an action potential which is capable of depolarizing the atria.
This depolarization is then followed by atrial contraction and an increase of the pressure in the atria.

Answer:
C
Explanation:
Green Plants are the main producers of starch as carbohydrate.In order to carry out this special organelle Chloroplast are specially adapted for this purpose,
Green plant are made up of Chlorophyll which are the green pigments that for trapping sunlight for the synthesis of starch to occur.
Photosynthesis is the process of synthesis of the starch.It involves the reaction of C02 with water in the presence of sunlight and enzymes to give oxygen as the byproduct, and Starch( carbohydrate) as the main product.
This process occur in two pathways the light dependent pathways and the light independent pathways,
Green plant and some organisms phytoplankons,algea are capable of producing starch through photosynthesis because of the green pigment they possess.Therefore they are said to be Autothrophic.
