Answer:

The starch indicator will take on a color between blue and black.

Explanation:

When you put a piece of potato in a glass of water, the starch in the potato will start to come out of the potato and stay in the water. After an hour it is likely that all of the potato starch is in the water.

When the starch comes in contact with the water in the cup, it starts to occupy the spaces between the water molecules, which means that we have a solution (starch + water), when the starch indicator is added to this solution, it reacts with the starch molecules and takes on a color between blue and black.

I think the government should have a plan or procedure in place to deal with the movement of the continents so as to curb species extinction.

<h3>What is Climate?</h3>

This is referred to as the atmospheric condition of a place for a long period of time.

Drifting of continents leads to a new climate being present which will affect life forms. If they are unable to adapt they may all die out and go extinct thereby disrupting the ecosystem which is why a plan should be put in place.

Nikitich [7]

Answer:

The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.

Explanation:

To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.

A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.
