Explain the connection between the oxidation of water in photosystem II of the light-dependent reactions and the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions.

Answers

Answer 1
Answer:

Answer:

Please find the explanation below

Explanation:

This question is describing the processes involved in photosynthesis. In the light-dependent stage of photosynthesis, specifically photosystem II (PSII), water is oxidized in a process called PHOTOLYSIS OF WATER. This process produces electrons and Hydrogen ions (H+). The electrons produced via this process is accepted by NAD+ to yield NADH.

The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).

Answer 2
Answer:

Final answer:

The oxidation of water in photosystem II of the light-dependent reactions is connected to the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions.

Explanation:

In photosynthesis, the oxidation of water in photosystem II of the light-dependent reactions is connected to the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions. In the light-dependent reactions, photons of light strike photosystem II and excite electrons, which then pass through an electron transport chain, leading to the production of ATP and NADPH. The ATP and NADPH generated in the light-dependent reactions are then used in the Calvin cycle to power the synthesis of glyceraldehyde-3-phosphate from CO₂.

Answers

"Nationalism in the Balkans" is the one among the following choices given in the question that has been mentioned by historians as a cause of World War I. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer has come to your help.

Answer:

Option A, nationalism in the Balkans

Explanation:

Eastern Europe cluster of nations lying between the Austro-Hungarian and Ottoman empires was known as Balkans. Due to its strategic location, all the Europeans powers focused on Balkans’ event. Also,  the Balkans were  politically active as they had both national ethnicity and tension with in its national territories.  

In 1912, several Balkan nations  became part of military alliances as influenced by the Russians which later on led to the  formation of the Balkan League. This Balkan league waged several wars against the Ottomans in order to remove them from eastern Europe. After fighting for eight months, Balkan won this battle but they were disrupted and thus Serbian nationalist groups and led to World War I

A 21-year-old female was lost in the woods for several hours. The ambient temperature is 25 degrees Fahrenheit. She is lethargic and confused. The skin on her hands is waxy and white. What should you do

Answers

The female should be gently wrapped with dry blankets due to exposure of temperature of about 25 degrees Fahrenheit.

Explanation:

Prolonged exposure to extreme heat or cold conditions can impair the body’s temperature control system.  

In the above case the patient is exposed to extreme cold condition in a wood with a freezing temperature of 25 degrees Fahrenheit (-3 degrees Celsius) which leads to hypothermia and frostbite.

Extreme cold conditions can freeze the tissue layers of the parts of the skin exposed like those of the face, hands and feet especially. Due to this the skin becomes white (even grayish yellow or blue) and waxy, cold and numb, and the outer surface may become hard and blistered. There will also be extreme pain, stinging and tingling sensation in the exposed areas.  

These changes are mainly due to impaired blood circulation and hypothermia. Hypothermia which is lowering of body temperature causes confusion and lethargy.

The first-aid given for frostbite primarily includes warming the body. The affected person’s body should be covered with warm and dry blankets gently and loosely and any wet clothes should be removed.  

So when the body is warmed, the body temperature also will increase and correct the hypothermic symptoms like lethargy and confusion.

Which of the following statements is NOT true about metabolism?a. Basal metabolism is the amount of energy needed for sustaining life.
b. Basal metabolism is measured by the amount of calories burned when your body is inactive.
c. Metabolism is influenced by numerous factors, such as heredity and age.
d. Younger people generally have a slower metabolism than adults.

Answers

Answer;

D. Younger people generally have a slower metabolism than adults.

Explanation;

Basal metabolism is the amount of energy needed for sustaining life. It is the basic, or least, amount of energy the body needs to survive when at rest. It does not include additional energy required to support even a small amount of activity.

Basal metabolism is measured by the amount of calories burned when your body is inactive. Factors, such as, gender, heredity and age influence metabolism of an individual.

Final answer:

The statement, 'Younger people generally have a slower metabolism than adults' is not true. Younger individuals often have a higher metabolism than adults because metabolism usually decreases with age. Metabolism is also influenced by many factors and basal metabolism refers to the energy needed for basic bodily functions.

Explanation:

All the statements about metabolism are true except for:

  • d. Younger people generally have a slower metabolism than adults.

The opposite is true. Younger individuals often have a higher metabolism than adults. This is because metabolism often decreases with age due to factors such as a decrease in muscle mass and physical activity.

Metabolism refers to the chemical processes that occur within a living organism in order to maintain life, and it is influenced by numerous factors such as genetics, age, diet, physical activity, and even the environment.

Basal metabolism is the amount of energy (measured in calories) your body needs to maintain basic bodily functions, such as breathing and circulation, when at rest. It accounts for about 60-75% of the calories burned each day.
