Answer:
The correct answer is energy. Other organisms are not necessary, just like offsprings since there are many organisms that never have offsprings. Light is also not necessary with numerous organisms, especially those like the ones that live deep in the sea where light never reaches. Some form of energy is necessary for everyone.

You did an experiment where you want to test if a special kind of fertilizer will actually help your apple tree produce a lot of apples. To do the experiment you went to your local nursery and purchased two of the same kind of apple trees. You planted both trees in your sunny backyard , gave both of them the same amount of waterbut you gave one tree the special fertilizer and the other tree with the regular old fertilizer you've used before . After about a month , you noticed that the tree that got the special fertilizer grew over 100 apples than the other tree that grew about 40 apples . From this experiment , which of the following is considered the dependent variable ?
Answer:
Dependent variable: number of apples
Explanation:
In an experiment, the independent variable is the variable that isn't modified by the other variables measured in the experiment. In the example above indicated, the independent variable is the fertilizer used in the experiment. On the other hand, the dependent variable is the variable tested or measured in the experiment, thereby this variable is 'dependent' of the independent variable.

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.
Hope this helps!
Answer:
Answer is B
Explanation:
I got 92%, so there's a 2/25 chance that this answer is wrong, pls tell me if it's wrong

Collecting research data is the final step in the scientific method.
true or false
Answer:
False
Explanation:
Edg
Collecting research data is not the final step of the scientific method. Deriving a conclusion from the collected data is the final step. Hence, it is false.
What are the steps in a scientific method?The scientific method is a process in which data is collected, observed and then a conclusion is derived. The scientific method is a very useful method in technology, computers, and business.
The following steps are involved in the scientific method:
First of all, is asking a questionCollecting dataPerform researchEstablish hypothesisConduct an experiment to test the hypothesisMake an observationAnalyze the resultDerive conclusion.Deriving a conclusion is the last step in the scientific method, while data collection is the most important step in data collection.

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.

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.

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.

Which of the following is not controlled at the individual level?
Response
Genetic code
Growth and development
Evolution
Answer:
Evolution
Explanation:
Evolution is the change that occurs to a particular species of a population from generation to generation. This change is due to the alteration in their genetic composition, which is inherited over time.
However, this change do not occur at the individual level but rather it occurs to a population i.e. only a POPULATION undergoes evolution process not individual organisms. Note that, the other options including genetic code, growth and development, response are controlled individually by the organism, however, the evolution process takes time and occurs over a population rather than to individuals

organisms
Answer:
Unity is the other name of cohesion.
Explanation:
The property of cohesion is to sticking together of something. The molecules of liquid stick together with the help of cohesion. This cohesion property is very important for plants because with the help of this property, plants take water through roots from the soil and the water molecules are stick together with the help of cohesion. If cohesion is not present then the uptake of water can not be possible.
