Explanation:
Photosynthesis is a process taking place in the green plants which are involved in the formation of the glucose molecule using Carbon dioxide and water in the presence of sunlight.
The process of photosynthesis takes place in two phases:
1. Light-dependent phase
2. Light independent phase
<u>Light-dependent phase
</u>
Light-dependent phase takes place in the thylakoid membrane where the Photosystem I and II are present.
The photosystem II absorbs the sunlight of 680 nm wavelength which excites the electron of the chlorophyll. The electron moves in the photosystem and through the reaction center-exit the photosystem and enters the electron transport chain.
The electron is then transferred via the electron carriers like plastoquinone, cytochrome, and plastocyanin and is transferred to photosystem I which absorbs the light at 700 nm. From here the electron is taken by ferrodoxin and form NADH.
The electron then reaches the ATP synthase and forms the ATP molecules thus ATP and NADPH are formed in the reaction but the loss of electron in chlorophyll is fulfilled by the water molecule which on hydrolysis provides the electrons and stabilize the structure.
<u> Light independent phase
</u>
The phase during which the Rubisco enzyme binds with the carbon dioxide and forms 3-PGA. This 3 PGA is then reduced to G3P which requires the 6 ATP molecules. The G3P molecule then forms 1 molecule of glucose and the Rubp is again regenerated.

Answer: Systolic pressure.
Explanation:
Every time the heart beats, it pumps blood into the arteries, which are vessels through which blood circulates from your heart to your tissues with the oxygen and nutrients they need. Blood pressure is the force of the blood pushing against the walls of the arteries, and is highest when the heart beats, pumping blood, which is measured as systolic pressure (i.e., when the heart contracts). On the other hand, diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats (i.e., when the heart relaxes). Since there are two types of pressures, blood pressure readings are given in two numbers, with the top number being the systolic pressure and the bottom number being the diastolic pressure.
For example, if the systolic pressure measured in a person is 125 millimeters of mercury (mm Hg) and the diastolic pressure is 85 mm Hg, the blood pressure is recorded as 125/85.
So, <u>the systolic blood pressure is registered with the stethoscope when the cuff is deflated.</u> When two heartbeats are heard, the pressure gauge reading is recorded. <u>When the heartbeat ceases, the cuff pressure is released and the diastolic pressure is measured at this time.</u>
