The foreign DNA is placed in a biological vector for cloning.
The foreign DNA is inserted into the host cell genome.
The foreign DNA is isolated by restriction enzymes.
Answers
After target genes are identified and isolated, they are usually inserted into a transfer factor. In the process of creating genetically modified crops, the transfer factor is plasmid (a circular DNA molecule) from a soil bacterium Agrobacterium tumefaciens. Therefore, the transfer vector in which the foreign DNA is placed is a biological vector. It is not artificially produced but isolated from the living bacterium.

Final answer:
The structure of the stigma aids in pollination by being specifically designed to capture and trap pollen. It is sticky or feathery, allowing it to collect pollen efficiently when a pollinator visits the flower. The specific structure also helps prevent pollination from different species, thus maintaining species purity.
Explanation:
The structure of the stigma greatly aids in pollination because it is specifically designed to capture and trap pollen. The stigma is the top part of a flower's carpel, and it has a sticky or feathery surface that enables it to collect pollen efficiently. When a bee or another pollinator visits a flower, the pollen sticks to its body and is transferred to the stigma of the next flower it visits. This transfer process, facilitated by the structure of the stigma, is known as cross-pollination.
The precision of the stigma's structure in different species also aids in the prevention of unwanted pollination from different species, helping in maintaining the purity of the species. Thus, the structure of the stigma plays a crucial role in the plant reproduction process.

A reference to the Sun! The chemical reaction that results from the energy of light leads the molecules of water and carbon dioxide to disintegrate and then reassemble into molecules of glucose and oxygen gas. After the sugar is created, the mitochondria convert it into energy that can be used for growth and repair. Thus, option B is correct.
What is the source of plant's energy comes from?
Water and carbon dioxide are converted by plants into a sugar called glucose using the power of the sun. Glucose is used by plants as a fuel source and to make substances like cellulose and starch.
Cellulose is used to build cell walls. Starch is preserved in seeds and other plant parts for use as a food source.
Therefore, The sun provides the plants with the energy they need to develop and prosper. The plants would not be able to survive if it were always dark outside.

Diploid gametophytic generation alternating with haploid sporophytic generation
Diploid sporophytic generation alternating with haploid gametophytic generation
Answers
Answer
The correct answer would be "Diploid sporophytic generation alternating with haploid gametophytic generation"
Alternation of generation refers to the type of life cycle often observed in lower plants. In this life cycle, plants alternate between diploid and haploid stage.
For example, a diploid sporophyte produces haploid spores through meiosis
The spores mature into haploid gametophyte which produces haploid gametes through mitosis.
The gametes fertilize and restore the ploidy by producing a diploid zygote which matures into a diploid sporophyte.
