According to evolutionary theory and the fossil record, which type of plant appeared just after this gymnosperm?

angiosperm

Explanation:

It was during the Devonian Period when gymnosperms evolved from the seed ferns

However, gymnosperm are plant species whose seeds are not confined in an ovary. For example - conifer

In the period of Mesozoic era , the scorpionflies ( species feeding on pollination drops) carried out pollination of gymnosperm and led to the coevolution of insects feeding on nectar which later on drove the evolution of angiosperms and also themselves.

Thus, it can be said the flowers and its pollinators evolved simultaneously.

hence, the answer is angiosperm.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

hi there!

answer: b. nucleolus

explanation: nucleolus is a structure in the nucleus are ribosomes are made.

hope this you!

have a nice day! : )
