Economists often use an economic model that reflects the total amount of goods and services required at all possible price level
pshichka [43]
The answer is letter D.
<span>
Economists often use the aggregate supply and demand model to reflect the total amount of goods and services required at all possible price levels during a specific period. It reflects the overall price of foods and services in an economy for a given period and is often illustrated with the supply-demand curve. This shows the relationship between price levels and quantity of output that a particular firm is willing to provide to the general public.</span>

High Energy electrons are transported from the chlorophyll to other molecules in the chloroplast by?
Reil [10]

Explanation:

High-energy electrons are transported from the chlorophyll to other molecules by electron carriers beginning with pheophytin, P0 (a form of chlorophyll), then A1 phylloquinone etc.

The chloroplast is an organelle attached to the membrane found in plants. This comprises many plasma membrane invaginations called the thylakoid membrane. It contains chlorophyll pigments, called granum in rows, while the organelle's internal areas are called the lumen. Water fills the granum and the stroma is created.

Further Explanation:

<em>During the light reaction: </em>

  • Photosystem II  (PSII) contains pigments which consume light energy. This energy is exchanged between pigments until it enters the reaction core and is moved to P680; this transfers an electron to a higher level of energy where it then travels to a molecule of acceptors.
  • For those removed from photosystem II, water supplies the chlorophyll in plant cell with substitute electrons. Additionally, water (H2O) divided into H+ and OH-by light during photolysis acts as a source of oxygen along with functioning as a reducer.
  • The electron moves down the electron transport chain via several electron carriers
  • The e- is delivered (to PS I) where it has a continuous loss of energy. Such energy drives the drainage of H+ from the stroma to the thykaloid, which results in a gradient creation. The H+ pass down their curve, passing into the stroma by ATP synthase.
  • ATP synthase converts ADP and Pi to the ATP molecule, which stores energy.
  • The electron enters Photosystem I where it heads to P700 pigments. It's. This consumes light energy, transfers the electron to a higher energy level, and moves it on to an acceptor electron. This leaves room for another electron which is then replaced by a photosystem II electron.
  • In the ETC the NADP molecule is reduced to NADPH by supplying H+ ions. NADP and NADPH are vital to the Calvin cycle, in which monosaccharides or glucose-like sugars are produced after several molecules have been modified.

A patient's HDL, LDL, and triglyceride levels are 62, 77, and 60, respectively. What is the patient's total cholesterol score? S
Len [333]

Answer:

Total cholesterol score is 199

199 is high cholesterol score especially as it very close to 200. The patient should adopt diets that do not include high cholesterol food

Explanation:

a. Firstly, we want to calculate the patient’s total cholesterol score.

To get this, we use a mathematical approach.

Mathematically;

the total cholesterol score = HDL + TDL + Triglyceride = 62 + 77 + 60 = 199

The patient’s total cholesterol score is 199

b. As a doctor, I will advice the patient on the status of these measurements. Using the scale of cholesterol level, a measurement of total cholesterol = 200 represents a high cholesterol level. Since 199 is very close to 200, the patient is at a risk of high cholesterol levels and thus needs a dietary change.
