The statement "<span>A strand of DNA serves as a model of the synthesis of RNA molecules" is totally a false statement. Each and every DNA strand only serves as a template or a model for the formation of other DNA molecule which was called as the process of replication.</span>
Answer: it is working out by doing exercises that quickly accelerate your heart rate
Explanation:
A good example is running on a treadmill or jump and jacks
Two factors contributed to the success of the pteridophytes: the extreme miniaturization of the gametophytic generation and an important development of the sporophytic generation (development of the tree forms).
Pteridophytes are a group of plants that peaked in the Carboniferous (-300 million years). It is the first great terrestrial plant civilization. These plants would have appeared in the Devonian -400 million years ago, perhaps from certain primitive terrestrial plants which, unlike bryophytes, would have favored the diploid generation on the haploid generation.
Particularly well adapted to terrestrial life, they have created, thanks to the development of tree forms, immense forests whose fossilization is at the origin of coal deposits.
Pteridophytes are at the origin of an evolutionary lineage based on the extreme miniaturization of gametophytic generation and an important development of sporophytic generation, leading to all tracheophytes including current flowering plants. Pteridophytes are well adapted to terrestrial life, however fertilization still requires the presence of water since male gametes are swimmers.
The correct sequence of these events (origin of mitochondria, origin of multicellular eukaryotes, origin of chloroplasts, origin of cyanobacteria, origin of fungal-plant symbioses), from earliest to most recent, in the evolution of life on earth is 4, 3, 1, 2, 5.
The transition to eukaryotic cells seems to have taken place in the Proterozoic Era, around 1.2 to 1.5 billion years ago. Nevertheless, the latest genetic studies propose the divergence of eukaryotes from prokaryotes nearer to 2 billion years ago.
Margulis suggested the mechanism of endosymbiosis, to describe the origin of mitochondria as well as chloroplasts from persistent living prokaryotes. In accordance with this idea, a bigger prokaryote engulfed or enveloped a smaller prokaryote around 1.5 billion to 700 million years ago.

Answer: What stage of succession is taking place in the forest?
The first stage of forest succession is the grass, or plant stage, which occurs after land has been cleared due to natural events or otherwise. The sudden clearing floods the ground with sunlight; very shade-intolerant pioneer species like longleaf pine, aspen, or cottonwood begin to compete with grasses.
What three major processes contribute to succession?
Causes of succession
Three major causes have been identified for the process of succession. a. Initiating causes - These include biotic and climatic factors which destroy the existing populations of the area. Climatic factors include wind, fire, natural disasters, erosionWhat are the 4 stages of succession?
There are five main elements to ecological succession: primary succession, secondary succession, pioneer and niche species, climax communities and sub-climax communities.
