Answer #1

we will consider these characteristics ..

1.Bryophytes--if it has a thallus like plant body ,rhizoids present or sporophyte differentiated into foot seta capsule and plant body may differentiated into root like,stem like,leaf like structures which aren't true structures . Plant body will be fragile .. body is not cutinised ..

And there won't be no vascular system in plant body ...

2.Fern-- ferns belong to a very old group of plants in middle Devonian era 360 million years ago .. vascular system not well developed ..seedless plants (seed absent ) .They have true root stem and leaves ..

3..gymnosperms -- naked seed may present ..there will be no flowers .. vascular system developed and vessel absent in most of gymno sperms ..vascular system developed ..sporophylls present ..gametophyte reduced ..

You are researching what you are hoping is a new rare native plant species found in a newly-restored habitat. You are anxious to understand what kind of plant it is and help it become established and grow well. Your colleague shares her observations: the plant has a sizeable taproot, leaves with branched veins, and flowers with five petals. When transplanting to a new location, you notice that some of the plants have knobby growths on the roots. The plants with...

Imagine you discovered the fossil shown reconstructed to the left, Rodhocetus kasrani. The area where the fossil was found was coastal with large, shallow seas at the time the fossil was dated to. Rodhocetus kasranihad short limbs,long finger bones, a streamlined body, an unfused sacrum, and a long tail(these are all also features of modern whales). It was likely semi-aquatic, spending a lot of time in water, but its limbs could also support itself on land. 3) As a paleontologist,...

Imagine that you have the DNA sequences from the intron of a gene in three species called A, B, and C. Species A and B are most closely related, while C is more distantly related. The sequences of A and B differ by 18 base pairs, A and C differ by 26 base pairs, and B and C differ by 28 base pairs. Fossils show that species A and B diverged about 1.2 Mya, but there is no fossil evidence...

Suppose your research team found a brand new gene that may be involved in the early stages of embryonic development. In studying this gene, your team manages to identify the promoter region and one enhancer region that is 1,000 kilobases upstream of the promoter region. To study this gene’s expression during embryonic development, would you choose to fuse a reporter gene, like GFP, with the promoter region or the enhancer of your gene of interest? Why would you choose that...
