The surface of the early Earth is often described as hellish by scientists. The high temperature is primarily attributed to the high levels of carbon dioxide in the atmosphere and the molten rock on the surface of the planet. However, these two aren't the only factors in play.
Another factor that contributed to the extremely high temperature of the early earth is radioactivity. Radioactive decay of the isotopes found underground plus the left over heat from the formation of our planet produced high levels of radiogenic heat.
There's also the kinetic energy from falling asteroids and meteorites. Massive amounts of energy in the form of heat and sound is produced when asteroids and meteorites hit the Earth. Also, the pressure waves that travel radially outwards the center of the impact is similar to the impact of an atom bomb. As such, dust particles envelop the atmosphere, trapping the heat from the impact.
The last factor is the gravitational contraction, it contributed to the hellish temperature of primordial Earth because the energy generated from such event is enough to trigger hydrogen fusion.
Herbivorous are the primary consumers
The primary consumers are herbivores animals sch as cows,goats,and elephants. They consume plants. Plants are the producers. To be able to extract energy from plants,herbivores must eat a large chunk of plant materials which explains why herbivores has to eat consistently.
A substance that can be used or prepared for use as food
Answer:
A molecule of mRNA is formed.
Explanation:
Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.
The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.
The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.
Note: A molecule of mRNA is formed during transcription
Answer:
The correct option is D. The average mass of plants exposed to 3 g of herbicide was 10g.
Explanation:
As the vertical axis is labelled as average plant mass, it will make the y- coordinate.
As the horizontal axis is labelled as Herbicide (g/plant), it will make the x-axis.
The coordinates for the given value are (3,10). 3 will be the value of the x- coordinate. Hence, it will show the average mass of the plant at the plotted point which will be 3 g.
10 will show the value of the y- coordinate which will be the amount of herbicide given to the plant.
Hence, Dis the correct option.
