what is the correct formula for photosynthesis? [A. C6H12O6+6O2+6H2O->6CO2+12H2O] [B. 6CO2+12H2O->C6H12O6+6H2O+6O2] [C. 12H2O+C6H12O6->6CO2+3O2+3H2O] [D. 6CO2+12H2O->C6H12O6+3H2O+6O2]

Answers

Answer: The correct answer is B. 6CO2 + 12H2O → C6H12O6 + 6H2O + 6O2

Photosynthesis is a process of synthesis of food in green plants and algae. In this process, energy from sunlight is absorbed by chlorophyll pigment in the presence of CO₂ and H₂O and it is used for the formation of food, which is a carbohydrate ( glucose).

Thus, CO₂ and H₂O are used as reactants and glucose ( C₆H₁₂O₆) is synthesized as a final product of the process along with O₂ ( oxygen).

Option B) is the correct balanced equation for this process.

Answer:

B. 6CO2 + 12H2O → C6H12O6 + 6H2O + 6O2

What is the name of the valve that is located between the right ventricle and right atrium? A) bicuspid B) tricuspid C) aortic D) pulmonary

Answers

B. Tricuspid Valve is located

Final answer:

The valve between the right atrium and right ventricle is the tricuspid valve, which helps prevent backflow of blood.

Therefore , the correct answer is (b).

Explanation:

The valve that is located between the right atrium and the right ventricle of the heart is referred to as the tricuspid valve. This valve's job is to prevent the backflow of blood into the right atrium when the right ventricle contracts. The tricuspid valve has three flaps or cusps, which is where its name comes from. The other options listed, such as the bicuspid, aortic and pulmonary valves, are located in other parts of the heart.Therefore , the correct answer is (b).

The chaparral biome is generally characterized by its terrain.

True or False?

Answers

I believe this would be false. Chaparral biomes can have many different types of terrains. The land in a chaparral biome can be mountainous, rocky, or flat. Chaparral biomes are generally defined by their temperature and climate. They are very hot and dry, and have mild winters and extreme summers. Hope this helps.

Which of the bonding examples below is NOT possible?(A) a DNA adenine to a DNA thymine
(B) a DNA adenine to an RNA thymine
(C) a DNA guanine to an RNA cytosine
(D) a DNA adenine to an RNA uracil
(E) a DNA guanine to a DNA cytosine

Answers

B is not possible. RNA contains only adenine, cytosine, guanine and Uracil instead of Thymine. The rest are correct because Adenine pairs with either uracil (RNA) or thymine (DNA) and cytosine pairs with Guanine
