Golden algae are a group of protists whose color is due to carotenoid pigments: yellow and brown. Most have two flagella and all are photosynthetic. A group of students was given a sample of one of these (Dinobryon) that is colonial. Their instructions were to design two or more experiments that could be done with these organisms. The students decide that for one of their experiments, they want to see whether the organisms can photosynthesize. Which of the following is the most appropriate hypothesis for their experiment? a. If the Dinobryon are kept in the dark, then one-half will be expected to die in 5 days.
b. If the Dinobryon can live without exposure to light for > 5 days, then they must be able to photosynthesize.
c. If the Dinobryon can live > 5 days without added food, then they must be able to photosynthesize.
d. If the Dinobryon are able to photosynthesize, then they should contain photosynthetic pigments
e. If the Dinobryon photosynthesize, then they must need no other minerals or nutrients and will be able to live in distilled water and light alone.

Option-D

Step-by-step explanation:

Golden algae are the protists which can photosynthesize and possess flagella. In the given question, a hypothesis has to be proposed which could explain the photosynthesis process in the golden algae process.

A hypothesis is a predicted statement which is based on the previous knowledge and can explain the natural event in. Also, the hypothesis can be tested with the experiments.

The hypothesis shows the possibility of the natural event therefore hypothesis begins with the If the word. In the given question, the statement that if Dinobryon can photosynthesise then they should contain the photosynthetic pigments is considered correct hypothesis which can be tested through the experiments.

Thus, Option-D is the correct answer.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
