Answer:

Effect of independent variable is studied on the dependent variable or subject of the experiment.

Explanation:

The independent variables are very important in an experiment. Basically the affect of an independent variable is studied on the subject or dependent variable.

Thus, it can be said that independent variable will produce the effect on the dependent variable.

Here in this case the different types of disinfectants are the independent variable and their effect will be  observed on the bacteria (subject or dependent variable)

Ipatiy [6.2K]

Answer:

tentatively group it with birds and speculate that the trait shared only with bats is a derived rather than an ancestral trait with bats.

Explanation:

The scientist after his observation should tentatively classify this organism with birds and the the second end of calculating the other morphological traits which makes it possess the likely bat traits to be ancestral.

According to scientists, most widely used modern systematic practice

depends upon the assumption that a change from character in one species

to character occurs once and once only in the evolutionary process and that this process is irreversible so that it never returns.

In this scheme, there are no independently derived parallel evolutionary changes,

nor convergences from a variety of states to a single one. Therefore, when two organisms share a

character state different from other species, it is because they are more closely related to each other through a recent common ancestor than they are to other species.

Also using the parsimony principle, a scheme of common ancestry for all the species is derived that uses all the characters that have been observed.

During dehydration synthesis is 42 water molecules were made how many monosaccharides were joined together to make the complex c
netineya [11]

Answer:

43 monosaccharides will be joined together to make the complex carbohydrate.

Explanation:

The complex carbohydrates are synthesized by the joining of monosaccharide residues by glycosidic linkages.One glycosidic linkage joins two monosaccharide residues by the elimination of one molecule of water.

  In other words it can be said that elimination of one water molecule joins two monosaccharides.By the same way elimination of 42 molecules of water will result in the joining of 43 monosaccaride residues.

amm1812

Answer:

It led to a wide range of protests by the people which brought about revolution

Explanation:

The ultimate consequences of wealth inequalities during the 18th century was wide range of protests by the people which brought about revolution.

This was because of the high poverty rate and difference between the classes in the society as the rich got richer due to policies which favored them while the poor got poorer due to the bad policies which made them register their displeasure and move for a revolution.
