<h3>{Differences in Physical Characteristics}</h3>
Vertebrates have a skeletal structure with a spinal column or backbone.Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.
Explanation:
<h3>{Invertebrates}</h3>
•Invertebrates do not possess a backbone not an internal skeleton.
•Invertebrates have an exoskeleton.
•Body size varies but most are generally smaller than vertebrates. However, some invertebrates grow to gigantic proportions – such as the colossal squid (46 feet in length).
<h3>{Vertebrates}</h3>
•Vertebrates possess a backbone and an internal skeleton.
•Vertebrates do not possess an exoskeleton.
•Generally, vertebrates are comparatively larger than invertebrates
Answer:
The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".
Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.
They show alternation of generation in which sporophyte is the dominant stage.
The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.
The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.
The gametes fertilize to produce a diploid zygote.
The zygote divides mitotically and matures into the diploid sporophyte.
During electrophoresis, the fragment that travelled the furthest will be the smallest one. So if it's coming from top to bottom, then the band closest to the bottom will be the smallest one.
