Explanation:

-The increased light intensity increased the rate of photosynthesis.

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.  Since photosynthesis is rate limited, the rate of energy intake can be increased in order to speed up photosynthesis, by speeding up photolysis.

  • 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

These end products, namely O2 and glucose are then used in respiration...

  • C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

The CO2 and H2O produced as waste in respiration can then be incorporated at the beginning of photosynthesis. Thus the reactions are cyclic- they feed into each other.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Respiration and photorespiration both utilize oxygen for;

  • the production of ATP via the oxidization of pyruvate;
  • and the oxygenation of the molecule Ribulose 1,5-bisphosphate (RuBP), an organic molecule also used in photosynthesis, to form 3-PGA + phosphoglycolic acid,

∴ the rate of CO2 usage for photosynthesis where O2 is produced, outpaces the rate of O2 use in respiration and photorespiration.

sergey [27]

Answer: Option B) Photosynthesis

Explanation:

It is impossible for plants to release energy from glucose using photosynthesis because photosynthesis results in the formation of sugar molecules such as glucose.

6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy

From the equation, photosynthesis is seen to as a biosynthethic reaction not a catabolic one.

Thus, it produces energy-rich compounds like glucose not otherwise

What is intramembranous ossification? a. the formation of bone from preexisting hyaline cartilage models b. the formation of bon
Stolb23 [73]

Answer:

c. the formation of bone from within fibrous membranes

Explanation:

On the basis of formation ossification process is divided into two types:

1) Endochondral ossification : The process by which bone is formed from haline cartilage.

2) Intramembranous ossification : The process by which bone is formed by replacing a fibrous membrane and not from cartilage. This type of ossification occurs as follows :

  • An ossification center appears in the fibrous connective tissue membrane.
  • Bone matrix is secreted within fibrous membrane
  • Woven bone and periosteum forms.
  • Bone collar of compact bone forms and red marrow appears.

Hence option c. the formation of bone from within fibrous membranes is the right option

PtichkaEL [24]

Answer:

d

Explanation:

<em>The correct answer would be increasing heart rate to compensate for low cardiac output.</em>

The negative feedback loop is the mechanism that is utilized in the maintenance of homeostasis. They work by opposing the processes that bring about a deviation away from setpoints, that is, the normal range of operation of physiological processes in the body.

<u>For example, when the heart rate goes below the setpoint, the negative feedback loop swings into action through the sensor, the control center, and the effector to return the heart rate to the normal operating range.</u>

Correct option: d
