In which of the following relationships is one organism always benefited while the other organism is always harmed
marusya05 [52]

Answer:

Parasitism

Explanation:

Parasitism is the form of mutual relationship between two organisms which occurs in such a way that one organism always get benefit and the other always gets harm. The one getting harm may or may not be killed due to it.

There are many common parasitic relationships we see in eco system.For example, when a tick sucks blood out of a dog. it is causing harm to dog by decreasing the content of blood however getting benefit for itself since blood is its food and the nutrients present in blood are source of energy for tick.

Similarly, Malaria is caused in human by a parasite called plasmodium. It enters into the blood and causes a disease called Malaria which can even lead to the death of affected individual,the parasite itself stays healthy and gets benefit.

Hope it help!

1-The correct answers is C- evolutionary classification.
Evolutionary classification/taxonomy is a branch of biological classification. The objective is to classify organisms and group them based on their shared descent, progenitor-descendant relationship and degree of evolutionary change. Now this classification can be done by comparing DNA sequences of the organisms and seeing how many they have in common

2- The correct answer is A-cladistic analysis.
A cladistic analysis is focused on categorizing the organisms based on their derived characters. And what is that? that means they are getting categorized
according to their evolutionary relationships( from ancestral characters).
So, species are going to be classified according to how recent their common ancestor is. If two species have a more recent ancestor they will end up in the same group
If the common ancestor between them is far, the distance between the respective taxa will be bigger.

3- The correct answers is C.
A derived character is a characteristic that appeared throughout evolution, still remains in a lot of different taxonomic groups and allows us to identify those groups.
From the options given, C is the only correct one because the presence of hair (a derived character)  only exists in mammals( the group). Other animals don't share that trait.


4-The answer is A.
In each node, a taxon was only one but then was divided into two taxa. Therefore, each node will represent a common ancestor of the taxon.
The correct option is A because the last node or terminal node is the hypothetical last common ancestor of the taxon on the cladogram.

5-  The correct answer is A.-DNA can solve evolutionary puzzles.
Dna has been helping understand how an organism is similar to more than one species, and that way, we can classify the organism the best way possible.
This can be achieved by comparing the nucleotides of the organism we want to classify, with other species. There are databases that have all the DNA sequenced so, what's left to do is count the common nucleotides and their positions.

How many times stronger is a pH of 14 vs. a pH of 8?<br> 6<br> 1,000,000<br> 600<br> 60
nirvana33 [79]

Answer:

B. 1,000,000

Explanation:

A pH of 14 is 1 x 10^-14 while a pH of 8 is 1 x 10^-8.

So, all we have to do is subtract 8 from 14 and then solve it.

14 - 8 = 6

1 x 10^6 = 1,000,000
