It takes just four hours for one bacterium to become _____.
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.

Explanation:
2.004 * 1^11 is not in scientific notation as there is no power of 10 written. We note that 2.004 * 1^11 equals 2.004, which can be written as 2.004 * 10^0.
The measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane is called...
A. Osmolarity
B. Equilibrium
C. Homeostasis
D. Tonicty
The osmotic gradient, which is the concentration difference between two solutions on either side of a semipermeable membrane, is used to determine a particle's concentration in a solution. Thus, Option A is correct.
What is osmolarity of a solution?Osmolarity, which is determined by the number of osmosis of a solute per liter of solution, is a gauge of solute concentration.
According to their relative osmolarity, solutions can be broadly characterized as hypertonic, hypotonic, or isotonic.
Osmolarity is important because cells cannot survive if their environment's osmolarity is significantly different from their own.
From a lower osmolarity to a greater osmolarity, water flows over a membrane. It switches from the diluted to the concentrated side, to put it another way.
Therefore, osmolarity measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane.

does the phase of the moon follow an pattern
Answer:
Yes.
Explanation:
The most obvious patterns of the moon are the phases of the moon, which move in a month-long cycle. Because the moon reflects its light from the sun, only the part of the moon that faces the sun is visible. ... Another quarter way through the cycle, the other half of the moon is visible; this is known as the third quarter.
Which statement describes a similarity between asexual reproduction and sexual reproduction? Both processes involve fertilization. Both processes involve cell division. Both processes produce genetically identical offspring. Both processes require two parents.
Answer:
The correct answer is B. Both processes involve cell division.
Explanation:
Both asexual and sexual reproduction involve cell division; they are means of creating offspring.
Only sexual reproduction involves fertilization, so we know that choice A is incorrect. Only asexual reproduction produces genetically identical offspring, so choice C is also incorrect. Finally, only sexual reproduction requires two parents, so choice D is not correct either.
This leaves us with choice B as the correct answer.

1) A class collected water samples from a nearby pond and wants to observe the samples for
microorganisms. Which microscope would be the most appropriate for the students to use?
A. Dissecting microscope
B. Compound light microscope
I
C. Transmission electron microscope
D. Scanning electron microscope
Answer:
Compound light microscope
Explanation:
This is the ideal microscope because it requires the passage of harmless beam of light through the specimen.Since the pond contain living creatures this is best to use.
C and D both require the transmission of beam of electrons through a sample. D depends on the reflection of the electron after scanning the specimen surfaces and sent this to the lenses of the observer.(C)involved the passing of the beam of electrons through the specimen the interaction of the electrons with the atoms in the specimen(,therefore in both cases these specimens can not be wet and living.
The specimen should be dry in both cases and therefore non -living ,because the chamber for the specimen must be a vacuum,and living organism can not survive in the vacuum. Thus pond water can not be used as specimen because the specimen in the water but me be living.
