<span>As the pollen tube penetrates the ovule, it releases two sperm cells. As in gymnosperms, the ovule becomes a seed, encasing the embryo and endosperm in a seed coat. But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization.</span>
B. Soil Contamination
All the other answers are talking about clean and pure things while this answer is the only negative one. So B is your answer.
Classroom bioprinters can be used to print literally any biological object, whereas a chemical engineer is responsible to use chemistry to develop processes and devices.
<h3>What is a bioprinter?</h3>
A bioprinter is a device that combines cells and transcriptional growth factors, in order to generate structures similar to tissues and organs.
Moreover, a chemical engineer is aimed at exploring the chemical properties of matter to develop processes and devices.
In conclusion, classroom bioprinters can be used to print literally any biological object, whereas a chemical engineer is responsible to use chemistry to develop processes and devices.

Answer:
The Lucille’s cells need Oxygen and glucose in order to function her body properly.
Explanation:
Our body breakdown the glucose using oxygen in order to produce energy.
By respiratory system we inhale oxygen and
By digestive system we digest food into glucose.
Our circulatory system transfer the Glucose and Oxygen to the all cells of our body,
Hence we can conclude that the Lucille’s cells need Oxygen and glucose in order to function her body properly.
Answer:
Phosphodiester bonds:"It is a co-v-a-l-e-n-t bond in which a phosphate group joins adjacent carbons through ester linkages."
- The 3’-end has a free hydroxyl group at the 3’-carbon of a sugar, and the 5’end has a free hydroxyl group or phosphate group at the 5’-carbon of a sugar.
Explanation:
Option- E: Is The best option to Choose from.
The phosphodiester bond links a 3' carbon to a 5' carbon in DNA and RNA.
