The correct answer is C. Lemon juice

Explanation:

The acidity of a solution depends mainly on their ph, in this way a pH from 0 to 6 indicates a substance is acid, a pH of 7 shows the substance is neutral and a higher pH shows a substance is a base which is the opposite to acids as bases accept hydrogen ions if dissolved while acids release them. Also, the lower the pH the most acidic a solution is. In this way, lemon juice has a pH of 2 and therefore is the most acidic in comparison to tomato juice with a pH of 4, water with a pH of 7 (neutral pH) and sodium hydroxide with a pH of 12 (base).

1. Name three types of evidence used to support the theory of evolution
Llana [10]

Answer:

1) Fossil evidence Support

2)Genetic evidence supports evolution.

Biological evidence supports evolution;

Explanations;

1)Fossil evidence Support evidence;

This gives the geographic information about many fossils, it gives evidence that two species with a common ancestor can have their development differently and in

different locations. The common ancestor term is crucial especially in

theory of natural selection . In this evidence there is prove that common ancestor is shared through comparison between modern plants and modern algae to fossil algae by scientist.

Examples are bones, exoskeletons, stone imprints of microbes as well as animals.

2)Genetic evidence supports evolution.

This provides the understanding of how traits are passed from one generation to another under the study of DNA, DNA which contains the information needed by all organisms need to grow and to maintain themselves.geneticmaterial are passed to offspring by parent during reproduction. There are code which is made up of different chemical sub unit known as base. posses by DNA that helps to to function properly.

represented by letter A, T, C, and G.

3)Biological evidence supports evolution;

In this evidence, details about how evolution can be observed within the physical structures of adult organisms. is provided. It is evidence that involves of structural evidence such as vestigial structure which means an organisms with organs and similar structures with different functions.

For Example, considering the bodies of whales which is an organisms,there are small leg bones that are vestigial.
