Answer:
Prokaryotes do not have introns, eukaryotes have introns
Explanation:
Prokaryotes do not have introns, eukaryotes do. Introns are regions of DNA that are transcribed but not part of the final protein. They interrupt exons, which are the coding parts of the gene. These are only present in eukaryotes.
Introns need to be removed before the mRNA can be translated into the protein sequence. This occurs by a process called splicing. The splicing machinery binds the junction between introns and exons and excises the intron. The exons are then fused together to create the mRNA.
Other processing steps occur to the eukaryotic pre mRNA to prevent it from being degraded in the cell. This includes adding a cap to the 5' end of the protein, and adding a poly A tail to the 3' end. One these steps are complete, the eukaryotic mRNA is complete.
The prokaryotic mRNA undergoes transcription and translation simultaneously because it doesn't require these processing steps.
I. Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits.
F. Seeds protect and nourish plant embryos, and fruits protect the seeds.
C. In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators.
B. Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals.
A. Flowers attract animal pollinators carrying pollen from other plants of the same species.
D. Floral parts of the saprophyte protect the reduced female gametophyte from drying out and from UV radiation.
Food is chewed in the mouth because it helps you break down larger particles of food into smaller particles this well help in swallowing and digesting your food. Without being able to chew it is most likely for you to get constipated or choke
