The question is incomplete. The complete question is - A student poured a solution of bromthymol blue indicator into three test tubes. Then, he placed and aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Brothymol blue turns from blue to yellow in the presence of CO2.
Which process would you expect the organisms in the test tubes to carry out-- cell respiration, photosynthesis or both? When would you expect each process to occur?
Answer:
Photosynthesis is the process of the formation of the food in case of plants in the presence of sunlight with the help of carbon dioxide, water and soil. The light energy is converted into the chemical energy.
The beaker is blue because plants uses carbon dioxide for their food preparation. When the beakers are kept in the dark place, instead of photosynthesis cellular respiration occur that made energy from the food for their survival.
Answer:
The correct answer is "The common ancestor of coyotes and domestic dogs is more recent than the common ancestor of red foxes and domestic dogs".
Explanation:
One of the fastest way to known if two species have recent common ancestors is to look if they have common taxonomic ranks. In this case we can conclude that The common ancestor of coyotes and domestic dogs is more recent than the common ancestor of red foxes and domestic dogs, because the coyotes (Canis latrans) and the domestic dogs (Canis familiaris) share the same genus (Canis). The common ancestor of foxes and domestic dogs is more ancient because red foxes (Vulpes fulva) do not share the same genus has domestic dogs (Canis familiaris).

Answer:
C, bacterial cells dividing
Explanation:
because these are simple, one celled organism, they don't reproduce with male and female, instead they go through mitosis which is when a cell divides into two to reproduce. while A does include this, since skin belongs to a bigger organism it doesn't count as reproduction. B talks about development/growth, and D talks about something completely different to reproduction. hope it helped
