Answer:
Option (B).
Explanation:
Genetic diversity may be defined as the number of total genetic characteristics of a species. Genetic diversity helps the population to adapt in the changing environment. Crossing over provides a source of genetic diversity.
Crossing over is the process of exchange of genetic material during the process of meiosis. Thus, crossing over increases the variation of genetic characteristic in the haploid gamete cells.
Thus, the correct answer is option (b).
Photosynthesis is the process of creating or producing energy from sunlight. This is a unique process employed by plants and oxygenic bacteria like Cyanophyta or Cyanobacteria. It is the chlorophyll, the green pigment in plants, that is primarily responsible for this process.
On the other hand, respiration occurs in most other living beings. The body's respiratory system allows it to obtain oxygen from the surrounding air.
The difference is that plants need sunlight to photosynthesize while other living creatures do not need it for respiration.
Also, plants take in carbon dioxide and expel oxygen in photosynthesis. Meanwhile, other living creatures take in oxygen and expel carbon dioxide. Thus, establishing an important mutual relationship between the two processes.
Answer:
The balance form of the equation is given below.
Pb(NO3)2+2KI ——-> 2KNO3 + PbI2
Explanation:
In this equation lead nitrate and potassium iodide are reactants while potassium nitrate and lead iodide are the products. In the unbalanced form of equation, two molecule of iodine are formed in the product whereas there is only one molecule of iodine is present in the reactant. So for balancing this, 2 value is put in front of potassium iodide but by putting 2, potassium is also double in the reactant so 2 is also placed in front of potassium nitrate in the product and the equation is balanced.
