3. How does ATP provide energy to your body?
Answer:
ATP(or Adenosine Triphosphate) provides energy to your body because it is a chemical that takes energy from the food you eat and turns it into energy your body can absorb. So because of this, it is considered a source of energy.

Answer:
Option B: Molecule 2
Explanation:
'Equilibrium of a molecule inside and outside a cell' means that there are similar numbers of that molecule on the inside and the outside. (hence 'equilibrium')
The number of each molecule is as follows:
Molecule 1 - Inside: 3, Outside: 5
Molecule 2 - Inside: 2, Outside: 3
Molecule 3 - Inside: 1, Outside: 5
Molecule 4 - Inside: 7, Outside: 4
Therefore the correct option is option b. 2
This is because the number of molecules inside the cell and outside the cell are the closest together, most similar out of all the molecules.
Hope this helped!

Describe the resulting cells of meiosis
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

__________ is weather averaged over a long period of time.
Question 2 options:
A. temperature
B. air pressure
C. climate
D. humidity
Answer:
no
Explanation:
no
The weather that is averaged over a long period of time is the climate that is present in Option C because climate is a prolonged period of weather that is taken into consideration, and the regions are specified for the climatic condition.
What is the climate?Weather is affected by various factors, such as temperature, humidity, etc., and that is not permanent for years, but it is temporary because when there is a rainy day, the weather condition of that place is more cold, while in a place where there is a high temperature, the weather becomes dry for that region. Climate is a weather condition that lasts for long periods of time, such as 20 or 30 years, and depending upon the climate, different ecosystems are considered.
Hence, the weather that is averaged over a long period of time is the climate that is present in Option C because climate is a prolonged period of weather that is taken into consideration, and the regions are specified for the climatic condition.

100 POINTS!!!!!!!!!!! ( I NEED FAST ANSWERS ) Why do we use uranium for nuclear energy?
Answer:
Uranium is the fuel most widely used by nuclear plants for nuclear fission. ... Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare.
Explanation:
i looked it up
Answer:
In a nuclear reactor the uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved. The heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity.

Will mark u brainliest.
Answer:
not sure how to go about this question so if I'm wrong please tell me
Explanation:
The difference between poison and medicine is that poison is used to harm to one's health whether its an animal or human while medicine is used to cure an illness or an injury. We can use science to figure out the difference by testing the substance on an animal or stem cells of a human scientists do this various times to be assured of its outcome.

A fish is swimming around the 720-meter perimeter of her pond. If she swims 10 laps in 120 minutes, what is her average speed in m/min?
Answer:
The average speed of the fish is:
60 m/minExplanation:
You must take into account that the fish swims 10 laps, so you must multiply the perimeter by 10 to obtain the total meters swam:
720 m * 10 = 7200 meters.Now, you just must divide the total meters swam by the number of minutes that the fish took to do this, so:
7200 m / 120 min = 60 m/minRemember, ever you do an exercise like this, you must check the units, I mean, the units that the exercise wants to be the same you use, in this case, the average speed of the fish is 60 m/min.

Erwin Chargaff is considered one of the pioneering scientists in the field of molecular biology. In one of his studies, Chargaff observed that a sample of human DNA contained approximately 30% adenine (A). Based on DNA structure, what are the expected percentages of the other nitrogenous bases in the sample?
A.
10% thymine, 40% cytosine
B.
20% thymine, 30% cytosine
C.
30% thymine, 20% cytosine
D.
40% thymine, 10% cytosine#
Answer:
30% thymine, 20% cytosine
Explanation:
In a typical DNA double helix pyrimidine; Cytosine and thymine always pair with Purine ;Adenine and Guanine. This pairing ensure that the double helix of DNA is maintained by the presence of Hydrogen between these organic bases.
For correct pairing all adenine must pair with thymine,and all Cytosine with guanine.Therefore for this to occur if 30 % of adenine is present,the composition and number of thymine(30%) must be available.If this percentage is not available the pairing will not occur.
Like wise 20% Cytosine must be present because ,then same amount of Guanine molecule 20% in the DNA molecule. must be present Thus Guanine percentage is 20%.
This give a total of 100(60+40)
This based on the Erwin Chargaff stoichiometric ratio of 1:1 .This states that the percentage of adenine =thymine,and that of Guanine=Cytosine,in the DNA of living cells should be equal. Thus; [A]+[G]=[C]+[T]=1:1
