By seeing how much the tectonic plates move
Explanation:
three new organisms ,x,y and z were discovered by a group of zoologists they observed that organisms x and y depend on organisms z for food . organisms z does not depend on oraganisms for food . oraganisms x is the . only one that can move on its own
Answer:
Evolutionary ideas do not contradict the thermodynamic laws, these ideas explain how descent with modification enables the organisms to have enhanced metabolic responses to fight against entropy
Explanation:
Organisms fight against entropy to maintain order within their cells and thus continue life. The debate about the association between the Second Law of Thermodynamics and evolutionary ideas emerged in 1900. During this period, it has been proposed that both ideas were contradictory, since evolution decreases entropy, while the second law states that systems increase entropy over time. However, the evolution does not contradict this law, because evolutionary ideas indicate the mode by which the organisms evolve to fight against entropy (for example, by enhancing enzymes responsible for protein degradation), while the Second Law of Thermodynamics literally states that the total amount of entropy of the whole system increases over time.
Answer:
B) Prokaryotic DNA is much smaller than eukaryotic DNA.
Explanation:
In biology, one event is correlated with the other event or structure like observed in the DNA. The genetic material of a eukaryote and a prokaryote differ from the other in many ways:
1. The prokaryote possesses only one chromosome which is double-stranded and circular.
2. The eukaryotic organism exhibits more than one chromosome which is not circular.
Since the prokaryotes possess very less amount of DNA then the eukaryotes therefore during DNA replication, the DNA of prokaryote require only one origin of replication from where the replication will start.
Thus, Option-B is correct.
The best answer is pneumatophores.
In the environment where mangroves grow, oxygen is very limited. This necessitates mangrove root system to take up oxygen from the atmosphere. For this purpose, mangrove species have specialized above ground roots called pneumatophores or breathing roots.
In some species, these roots are pencil sized and peg-like while in others they look like a knee. These roots have numerous pores through which oxygen enters into the underground tissues. In some plants, buttress roots function as breathing roots and also provide mechanical support.
