Answer:
YELLOW
Explanation:
Phenol red is a biological indicator used to monitor changes in pH. The phenol red indicator changes color ranging from yellow to pink with respect to changes in pH. In an acidic pH i.e. <7, the phenol red changes to a YELLOW color while in an alkaline pH i.e. >7, the phenol red changes to a PINK pH.
The presence of carbon dioxide (CO2) increases the hydrogen ion concentration (H+) of a solution (lowering its pH or making it acidic).
Therefore, in a reaction where CO2 is created as a product, it means the CO2 content of that solution increases. Hence, the phenol red solution will be shifting towards the YELLOW color in response to a decreasee in pH (acidic).
Families I think, pretty sure
Bacteria have been the very first organisms to live on Earth
Angiosperms are the most diverse
and successful plant group. It has double fertilization which leads to the
formation of an endosperm. It also has a stamen with two pollen sacs. It has a
phloem tissue that is composed of sieve tubes and companion cells.
Las especies invasoras son animales, plantas u otros organismos que se desarrollan fuera de su área de distribución natural, en hábitats que no le son propios o con una abundancia inusual, produciendo alteraciones en la riqueza y diversidad de los ecosistemas. Cuando son transportados e introducidos por el ser humano en lugares fuera de su área de distribución natural, consiguiendo establecerse y dispersarse en la nueva región se les denomina especies exóticas invasoras resultando normalmente muy dañinas
