quester [9]3 years ago
3 0

Answer: The correct answer is- Archaea and Eukarya.

As per the information about the (phylogenetic tree) given in the question,

the last branch of the phylogenetic tree begins with the line of Eukarya and then holds the species of the Archaea division, which includes those prokaryotic organisms that live in extremely harsh environmental conditions ( such as Methanobacterium, and extreme halophiles).  

As this last branch holds species of two domains ( from 3 domain system of classification that includes Bacteria, Archaea, and Eukarya) , which are Archaea and Eukarya as it begins with Eukarya and later on holds the species of Archaea.

Thus, it shows that Archaea and Eukarya are more genetically related.

Is the water we drink today the same as the water that dinosaurs drank? Why or why not?
lesya692 [45]

Answer:

Yes and no

Explanation:

The water we drink today is the same the dinosaurs drank because no new water has been created since. However, the cycling of water in the planet requires for it to travel from one sink to another in a process that may last millions of years. For example, the water the dinosaurs drank may have sank to the bottom of the ocean and remain there for millions of years and thus would technically not be the same that we drink today.

In the antarctic region, biologists noticed a sudden drop in the death rate of penguins. How will this affect their population?
frez [133]
So, a sudden drop in the death rate means that while everything stays the same, less penguins are dying: the penguins are living longer! This means that the population will increase: there will be more penguins at all times!

disa [49]

The most accurate statement about stress is that prolonged stress can harm the hippocampus. A significant portion of the brains of humans and other vertebrates includes the hippocampus.

Two hippocampus, one on each side of the brain, are present in mammals like humans. The hippocampus, which is a component of the limbic system, is crucial for the consolidation of information from short-term memory into long-term memory as well as for spatial memory, which is essential for navigation.

All animals fall under this class, with the exception of the subphylum vertebrates. This group of creatures lacks a backbone and can be found anywhere on the surface of the planet. These animal species can be found in the wettest rainforest canopy, the highest altitudes, and the driest deserts. called vertebrates.
