What is the difference between a eukaryote and a prokaryote in terms of what they have within in them?
Answer:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.
Mechanical advantage can be calculated as?
Answer:
Next we come to calculating the mechanical advantage of a lever. To do this, you divide the distance from the fulcrum, the point at which the lever pivots, to the applied force by the distance from the fulcrum to the resistance force. Using this picture, this means dividing distance b by distance a

Which of the following is the most likely reason the Moon can NOT support life?
А
It has many craters, indicating that it has an atmosphere too weak to protect life
B
It has many craters, indicating that is has a magnetic field too powerful for life.
С
It has many dark spots, indicating volcanic activity too extreme for life.
D
It has many light spots, indicating frozen ice that is too cold for life.
Answer:
A
Explanation:
B is not true because the amount of craters does not indicate how powerful the magnetic field is, it indicates how much gravity there is.
C is not true because the dark spots are igneous rock, dried lava. That means that there WAS volcanic activity, in the past.
D is not true because the light spots on the moon are not ice, they are simply a lighter colored rock.
A is true because meteors will burn up in the atmosphere of planets because of friction, so not all the meteors will hit said planet. But if there isn't an atmosphere, all of the meteors will hit that planet. (or in this case, moon)

Why is the series of reactions in the Calvin cycle called a
"cycle”?
Answer:
You can think of the Calvin cycle as being somewhat like a sugar factory within a chloroplast. It is called a cycle because, like the Krebs cycle in cellular respiration, the starting material is regenerated each time the process occurs. In this case, the starting material that gets regenerated is a compound called RuBP, a sugar with five carbons.
With each turn of the Calvin cycle, there are chemical inputs and outputs. The inputs are carbon dioxide from the air and the ATP and NADPH produced by the light reactions. The Calvin cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH. The cycle's output is an energy-rich sugar molecule. That sugar is not yet glucose, but a smaller sugar named G3P. The plant cell uses G3P as the raw material to make glucose and other organic molecules it needs.
Explanation:
You can follow the process of the Calvin cycle in the figure.
The series of reactions in the Calvin cycle are called a cycle because it involves inputs and outputs.
The Calvin cycle simply refers to the process that algae and plants use in turning carbon dioxide into sugar. The Carbon cycle is made up of steps such as Carbon fixation, reduction phase, carbohydrates formation, and the regeneration phase.
The series of reactions in the Calvin cycle are called a cycle because it involves inputs and outputs. The input molecules are ATP, carbon dioxide, and NADPH. On the other hand, the output molecules are ADP, sugar, and NADP.

Which of the following is released from ATP and therefore provides “energy”?
A) water
B) Pi
C) glucose
D) ADP and Pi
E) ADP only
Pi or inorganic phosphate is released from ATP and therefore provides energy.
What is ATP?It is the energy-carrying molecule found in the cells of all the living things. It is a nucleotide, which comprises three main parts, that is,
The nitrogenous baseAdenineRibose sugarA chain of three phosphate groups combined to riboseThe tail of phosphate is the actual source of energy, which is tapped by the cell. The accessible energy is present within the bonds between the phosphates and is discharged when the bonds are dissociated. It takes place via the supplementation of a water molecule, the process known as hydrolysis.
Generally, only the outer phosphate is withdrawn from the ATP to produce energy, when this takes place ATP get transformed to ADP or adenosine diphosphate.
Thus, the correct answer is option B, that is, Pi.

the cells of most prokaryotic cells have a what?
Answer:
hello Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
Bacteria are the only organisms characterized as
Answer:
Explanation:
prokaryotic
Bacteria are unicellular microorganisms characterized as prokaryotic.
What are bacteria?They are an extensive group of prokaryotic microorganisms devoid of a membrane that delimits the cell nucleus.
That is, because they are prokaryotic cells, they lack a nucleus or internal organelles, they can live in any habitat.
Therefore, we can conclude that bacteria are unicellular microorganisms characterized as prokaryote.

A laboratory assistant prepared solutions of 0.2 M, 0.4 M, 0.6 M, and 0.8 M sucrose but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. To determine the concentrations of each solution, the assistant filled four dialysis tubes with the four different solutions, took their initial masses, and placed each tube into distilled water overnight. The next day, the masses of each dialysis tube again were recorded. Using the data below, determine which concentration of sucrose solution is in each flask.
Answer:
To determine the flask on basis of the molarity or concentration of the solutions, an individual should design an experiment with the help of using water and dialysis tubes. Dialysis tubes up should be filled with pure water, then seal or closed them from both ends.
Measure the weight and note the mass of each tube, student should stick label the cups with the solutions. Weighing the solutions after leaving them for 8 to 10 hours. The tubes would lose weight as water leave the tube when placed in the solutions due to the principle of diffusion- movement.
The measure of the chemical constituents of the specific solute in a solution is called molar concentration.
For the determination of the flasks based on the molarity and concentration, the experiment should be designed based on dialysis tubes and water.
The dialysis tubes should be filled with pure water and both the ends of the tubes should be sealed.The tubes should be measured and marked. Place the tubes into the solutions and after leaving them overnight weigh them again.The weight of the tubes will decrease because of the flow of water.Therefore, due to diffusion movement, the tubes will lose weight and the concentration of the flasks can be determined.
