Answer:After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build food in the form of carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms. Where does the carbon come from? The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.
Explanation:The Interworkings of the Calvin Cycle
In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 5.14).
This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
Answer:
The correct option is b
Explanation:
Phospholipids are lipids that contains a phosphate group, which forms the "head" of the molecule and is hydrophilic (water loving). The "tail" of phospholipids is made of two fatty acids which are hydrophobic (water fearing). The phospholipid in the cell membrane acts as a selectively permeable barrier that regulates what goes in and out of the cell <u>thereby protecting the cell from some external molecules and ions</u>.
An electrocardiogram (ECG) provides information about B) the rhythm of heart contractions
The rhythm of heart contractions can be known by an electrocardiogram (ECG).
An ECG or Electrocardiogram is a method to diagnose the heart conditions to check the normal functioning of the heart.
The process to measure the electrical signals of the heart can be done by using this machine.
In this technique, three leads are attached to both the wrist and the left ankle to measure the electrical activity of Heart. The rhythm of the heart contraction and relaxation can be used to find out any heart abnormality.
It is used to investigate the heart problems associated due to bad health or some chronic inflammation affecting the functioning the body. Shortness of breath or nausea is investigated by using an ECG machine to help the patient and doctor to find out the cause.
It consists of QRS complex which measures the heart beat.

Answer:
The correct answer is movement; structure.
The muscular system helps with <u>movement</u> and the skeletal system helps with <u>structure</u>.
Explanation:
The human muscular system constitutes 40% of the total weight of our body and is made up of three types of muscles, which, together with different tendons and thanks to their contraction capacities, allow us to move. The muscular system and the function of the muscles allow the movement of our body and it is the one that works in tune with other systems of our body to guarantee normal general functioning..The skeletal system is the set of organs that support, shape, structure and protect the body. The skeleton is a dynamic structure, specifically the axial skeleton, it is to serve as a support or as a scaffold that supports the organs and structures of the body. This is how bones together with muscles work as a team to allow the mobility of the human body.
