Answer: 256 bacterium.
Explanation:
suppose a bacterium would divide once in every half an hour, this means it would be double in half an hour.
therefore, a number of the bacterium after half an hour will be 1 x 2 = 2.
After one hour, we would have doubled the number of bacterium =2 x 2
= 4.
Also, in one and a half hours, it would become 4 x 2
= 8.
In 2 hours, it would be 8 x 2 = 16.
Also in two and half hours, it would be 16 x 2
= 32.
In three hours, it would be 32 x 2
= 64.
In three and a half hours, it would be 64 x 2
= 128.
Funally, in four hours, the number of bacterium would have been multiplied to 128 x 2
= 256.
It takes just four hours for one bacterium to become 256 bacteria.
It should be noted that a bacterium will divide once in every half an hour. This implies that it'll be double in every half hour. Therefore, for an hour, there'll be 2 bacterium.
Since it doubles every half hour, in 2 hours, the value will be 16 bacteria. Therefore, the value in four hours will simply be:
= 16 × 16 = 256 bacterium.
Therefore, it takes just four hours for one bacterium to become 256 bacteria.

SCIENCEEEEEEEEE Frieda makes a pyramid of oranges for a display at the grocery store. A few minutes later, Corwin bumps into the display and the oranges spill down. Which change of state does the motion of the oranges most closely model?
The correct answer is A. Melting
Explanation:
Melting occurs in solids as these change their state to liquid state, usually due to high temperatures. For example, if one cube of ice is exposed to heat it melts. This physical change implies the solid loss its defined shape and particles in it are not as organized as before.
This process is exemplified by the situation of the oranges because the pyramid of oranges had a defined shape and the oranges were arranged in a defined pattern; however, in the end, this shape changes, and the particles (oranges) are no longer organized in a strict pattern. Also, the distance between particles increases, which also happens when solids become liquids.
Sabella works for an environmental safety group. Her group wants to answer the question "To what lengths must we go to protect plants and animals?" Why is her group's research question flawed?
Answer:
Explanation:
The main reason why the group's research question is flawed is because it steers more towards ethicality than science. It tries to find where the ethical line is and what "humans" are not willing to do even if it means protecting plants and animals. In order to focus on the scientific aspect the question should instead be rephrased as "How must we go about protecting plants and animals?"

Are flowers naturally rainbow colored? Please describe how the store can
have a rainbow colored plant (using the terms xylem or phloem.)
Answer:
Answer in explanation
Explanation:
Capillary action: Inside the stem, there are tube-like transport tissue, called xylem, that brings water and nutrient to different parts of the plant. Water molecules are attracted to the surface of the xylem cells by weak electrical attractions. This sticky property is called adhesion. Water automatically moves up the xylem due to adhesion and the resulting movement is called capillary action1.
Cohesion: Water molecules are not only attracted to the surface of xylem (adhesion), but they are also attracted to one another. This property is called cohesion. Because of cohesion, water molecules fill the column in the xylem as they move up and act as a continuous stream of water.
Transpiration: Water evaporates from the plant through transpiration. As water evaporates in the petals or any part of the plant exposed to air, a negative pressure is created in the xylem, resulting in suction pulling the water upward just like you draw water upward when you suck on a straw.
