Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant.
Answer:
The correct answer is "exchange of genetic information between parental chromosomes".
Explanation:
Homologous recombination is a genetic recombination that occurs when two similar or identical molecules of DNA exchange some of its nucleotide sequences. This type of recombination is most widely used for DNA repair purposes, however this is not distinctive of eukaryotes as prokaryotes use it as well. Therefore the most significant an unique role of homologous recombination in eukaryotes is the exchange of genetic information between parental chromosomes. This particular function is known as chromosomal crossover and it is only found in eukaryotes.
Answer:
The correct answer is B transcription factors.
Explanation:
Transcription factor are specific regulatory protein also known as sequence specific DNA binding proteins which regulates the process of transcription in eukaryotic cell.
Transcription factors may either turn on or off the expression of a particular gene to ensure that they are expressed in right cell along with perfect amount and manner.
Transcription factor such as helix turn helix ,leucine zipper, zinc finger play an important role in regulating the activity of many proteins such as DNA ploymerase, helicase
Electrons can also be created through beta decay of radioactive isotopes and in high energy collisions
i hope that helps and i’m sorry if it doesn’t
Answer:
The composition of the matter stays the same.
Explanation:
I am pretty sure that this is the answer because the matter itself is not changing, it is simply changing shape. it would only be a chemical change f the composition of the matter changed.
