Colour in water can be measured by eye. This process involves comparing a sample to a series of slides or tubes of various hues. However, this method is cumbersome and not suitable for certain types of contamination such as that resulting from industrial waste.

Answer: The aluminum atom  loses   electrons to form an ion.

                The ion that is formed is  <u>positive</u>

<u></u>

<u>Second Part of the question:</u>  What is the name of the aluminum ion?

<u> </u>Answer : <u>Al+3</u>

Explanation: <em>An aluminum ion has a charge of +3. It is not a neutral atom. It has a + charge, the electrons must have been taken away (electrons have a negative charge). Since the atomic number is 13, the number of protons is thirteen. In a neutral atom, there would be thirteen electrons. You take away 3. There is 10 electrons in Aluminum Ion. </em>

kodGreya [7K]

Answer:

Sedimentation.

Explanation:

The process that is responsible for the movement of carbon atoms from the biosphere to the geosphere is called sedimentation. Carbon enters the geosphere or lithosphere through the biosphere when dead organic matter becomes incorporated into the soil that turns the shells of calcium carbonate to become limestone through the process which is called sedimentation. This sedimentation process is very necessary for the formation of different types of minerals such as limestone, fossil fuels etc.

andrezito [222]

A phylogenetic tree<u> uses only 1 and 2 </u> whereas a cladogram does not. The group of answer choices includes the dimension of time indicates ancestral-descendant relationships use analogous character traits all of these.

A phylogenetic tree is a bifurcation diagram used to explain scientists' hypotheses about how branching between evolutionary lines occurred.

The most recent common ancestor of two taxa is the node that represents the fork between those taxa. In this case, the letter b represents the turning point between the gorilla and the human.

A phylogenetic tree is a bifurcation diagram showing putative relationships between different species based on similarities and differences in physical and/or genetic characteristics.
