Complete the equation for photosynthesis.
lesya [120]

Answer: Equation for photosynthesis is carbon dioxide + water + sunlight→ Glucose + oxygen

In light dependent reactions, energy in form of solar energy is absorbed and converted to chemical energy.

Explanation: During photosynthesis, sunlight is absorbed by the light absorbing pigment called chlorophyll. The absorbed solar energy is converted into chemical energy using carbon dioxide and water as the starting materials with the release of oxygen. The equation is 6 CO2 + 6 H2O + solar energy --> C6H12O6 + 6O2.

Photosynthetic reactions are made up of two parts: the light dependent reactions and the carbon fixation reactions. In the light dependent reactions, chlorophyll and other photosynthetic pigments absorb light energy from the sun and conserve it as ATP and NADPH with a simultaneous release of oxygen. The carbon fixation reactions are driven by the products of the light dependent reactions.

The mosquito Aedes aegypti has a diploid number of 6 chromosomes. How many DNA molecules and Chromosomes are found per cell when
zubka84 [21]

Answer:

Option C, 12, 6

Explanation:

The number of chromosome and DNA molecule are interpreted through the number of functional centromere and chromatids respectively at each phase of the cell division.  

However, the DNA number only changes in the S phase of the cell division as replication occurs in this phase only.  

Hence, after meiosis I two daughter cells will be formed with half the chromosome number i.e 3 and number of DNA is equal to 12.  

Now, till metaphase II no change occurs. Now at anaphase II DNA remains same while the chromosome number increases to 6

Thus, the correct answer is option C
