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.
A. archaea because lack a nucleus and cell organelles ·cell walls do not contain peptidoglycan
No solo seria natural porque son differentes y asy creses pero solo si isiste todo igual
Answer:
a. Anabolic pathways build molecules, require energy, and are endergonic.
Explanation:
<em>Anabolic pathway </em>describes the metabolic reactions that<em> </em><em>build up</em><em> complex molecules from simpler ones</em>, typically via condensation (monomers covalently joined producing water as a by-product).<em> It </em><em>requires energy </em><em>to construct new bonds, this means is </em><em>endergonic</em><em>.</em>
The catabolic pathway, on the other hand, describes metabolic reactions that<em> </em><em>break complex molecules down </em><em>into simple ones</em>, typically via hydrolysis (consumption of water to break bonds within the polymer). <em>It </em><em>releases energy </em><em>when these bonds are broken, this means it is </em><em>exergonic</em><em>.</em>
Considering this information we can conclude that the correct answer is a. Anabolic pathways build molecules, require energy, and are endergonic.
I hope you find this information useful and interesting! Good luck!
Answer:
The traits were linked
Explanation:
Gregor Mendel often called the father of genetics was a priest as well as scientist. He conducted many science experiments and determined the law of independent assortment and segregation. He did however noticed that there were some traits seen in the parents that were passed to the offspring in the same combination. These were termed "linked-traits" and were the first indications that genes may be linked.
