19. Use a Punnett Square to simulate a Bb x Bb cross between two flowers.
What is the probability that one of the offspring from that cross will have only the b factor:
a. 50%
b. 75%
c. 100%
d. 25%
Answers
25 % is the probability that one of the offspring from that cross will have only the b factor. So, the correct option is (D).
What is Punnett Square?
A Punnett square is defined as a specialized tool derived from the laws of probability that is used to predict the likely offspring from a cross or mating between two parents.
An example of a Punnett square which is shown in the attached image shows the results of a cross between two purple flowers, each with a dominant factor and a recessive factor.
Only one in four plants or 25% of the plants had white flowers (bb) containing only b while The other 75% have purple flowers (Bb, Bb), because the purple factor (B) is the dominant factor. This shows that purple color is the dominant trait in the plant.
Thus, 25 % is the probability that one of the offspring from that cross will have only the b factor. So, the correct option is (D).

Explain how nitrate ions help plants to grow.
Answers
Answer:
Explanation:
Both nitrate ions and ammonium ions can be taken up by plants (some prefer one to the other). These ions provide nitrogen for the plant to make its own amino acids for protein synthesis. Except in very high nitrogen soils, the addition of extra nitrate will stimulate plant growth.
Nitrogen is an essential macronutrient that is a component of many essential molecules, such as amino acids, proteins, nucleic acids, and chlorophyll.
What are the roles of nitrate in the growth of plants?Nitrate ions are essential nutrients for plant growth and development. Nitrogen is the fourth most abundant element in plants and is crucial for the growth of leaves, stems, and roots.
Plants require nitrogen in the form of nitrate because it is the most oxidized. It is an easily available form of nitrogen for plants to take up from the soil. Nitrate is absorbed by plants through their roots and transported to the plant cells, where it is used to synthesize amino acids, proteins, and other essential molecules.
Nitrate plays a crucial role in the process of photosynthesis, which is the process by which plants convert sunlight into energy.
