A student decides to set up an experiment to see if detergent affects the growth of seeds. He sets up 10 seed pots. 5 of the see

d pots will receive a small amount of detergent in the soil and will be placed in the sun. The other 5 seed pots will not receive detergent and will be placed in the shade. All 10 seed pots will receive the same amount of water, the same number of seeds, and the same type of seeds. He grows the seeds for two months and charts the growth every 2 days. What is wrong with his experiment?
A) There is no appropriate control
B) There is no way of measuring the outcome
C) More than one variable is being tested

Answer:

The correct answer is option C) "More than one variable is being tested".

Explanation:

One of the basis of scientific experimentation is to test one variable at the time in order to make sure that the response that is being obtained is the result of that variable and not another one that is not taking into account. In this case, the student is making the mistake of assessing two variables at the same time: the use of detergent and placing the plant in the sun or in the shade. At the end of the experiment the student will not know if the response is the effect of the detergent, the exposure to the sun or a combination of both.

Answer:

C) More than one variable is being tested

Explanation:

 In the experiment several variables are being studied, such as the influence of detergent on seeds and the intervention of the sun or shade on seeds with or without detergent. It should be both groups of seeds in the sun or both groups in the shade.

Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget y
Vera_Pavlovna [14]
Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario.

Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds  

Solution:
A = 45 m/s – 15m/s / 6s
A = 5m/s^2

Answer:

One difference between these cells is plant cell has chloroplast but animal cell does not have chloroplast.

Another difference between these is that plant cell has cell wall but animal cell does not have cell wall.

Explanation:

Plant cell are known to cells that possess chloroplast. These chloroplast contain chlorophyll which enables the plants to manufacture their own food. Animal cell does not possess chloroplast which makes it impossible for animals to manufacture their own food.

Plant cell actually have cell wall and a cell membrane but animal cell does not have cell wall but only possesses cell membrane. The cell wall gives mechanical strength and maintains cell shape.
