Four cars are positioned at the top of a hill. Which car has the most potential energy?
A. a small red convertible
B. a small race car
C. a large SUV truck
D. a BMW
Answer:
B
Explanation:
A race car has more power than a regular car/truck.
A small race car has the most potential energy because it has more power as compared to others. So, the correct option is (B).
What is Potential Energy?Potential energy is a type of stored energy that depends on the relative positions of different parts of a system. For example, a spring has more potential energy when it is compressed or stretched or a steel ball has more potential energy above the ground than after falling to the ground.
Any object that is raised from rest has energy stored in it so it is called potential energy as it has the potential to do work when released. The potential energy is expressed as
P.E.= mgh
where, m is the mass of an object
g= acceleration due to gravity i.e. 9.8m/s
h= height
It's SI unit is Joules (J).
Thus, a small race car has the most potential energy because it has more power as compared to others. So, the correct option is (B).

Why was the transaction from purple bacteria to green bacteria important for the evolution of complex organisms
Answer:
The consensus of the photosynthesis Gene trees also indicates that purple bacteria are the earliest emerging photosynthetic linage. Heliobacteria and green sulfur bacteria indicate that they synthesize photo systems that are ancestral to the photo system 1.
Explanation:
Answer: More complex life forms, including plants and animals. Green bacteria were important because they allowed some organisms to make energy from the sun.
Explanation: The green bacteria also released oxygen in the atmosphere, allowing for more diverse forms of life on Earth.

Why is it difficult to find evidence of potential energy?
Explanation:
Potential energy is the latent energy in an object at rest, and is one of two forms of energy. The other form, kinetic energy, is the energy expressed by an object in motion. Potential energy is a core concept of any physics-based discussion, and one of the most influential variables in the formulas that describe our known universe.

A scientist is comparing the outer structure of an onion cell, structure X, to the outer structure of a human skin cell, structure Y. Which generalization is true about the types of structures being examined?
Structure X is not living, and structure Y is living.
Structure X can be found in some human cells, and structure Y can be found in some plant cells.
Structure X is only found in plant cells, and structure Y is found in plant and animal cells.
Structure X is semipermeable, and structure Y is selectively permeable.
Answer:
Structure X is only found in plant cells, and structure Y is found in plant and animal cells.
Explanation:
The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.
Structure X is not living, and structure Y is living. - this is false, both animal and plant cells are living.
Structure X can be found in some human cells, and structure Y can be found in some plant cells. - this is false, the opposite is true.
Structure X is only found in plant cells, and structure Y is found in plant and animal cells. - this is true structure X is the plant cell wall, and structure Y is the cell membrane
Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.

respond to EGF.
C) Calculate the mitotic index (number of cells in mitosis divided by total cells) for each kind of cell.
Compare the mitotic rates for each cell type
D) Predict the cause of rapid growth in the cancer cells observed in experiment 2. Justify your
answer with evidence and reasoning.
Answer:
This is what I put (its kinda bad so don't judge)
Explanation:
A) Examining Table 1 with cancerous cells and HeLa cells we can see that with both HeLa and cancerous cells when treated with EGF increase in cells. Examining Table 2 we can see that HeLa cells create the most cells when treated with a concentration of 25 ug of EGF.
B) Normal cells increased by 33 when treated with a concentration of 10 ug of EGF. Cancerous cells increased by 405 when treated with a concentration of 10 ug of EGF. We can conclude from this that the cancerous cells multiply faster than normal cells with a concentration of 10 ug of EGF.
C) The mitotic index of HeLa cells with zero EGF treatment is 11 mitotic figures noted per 73 high power fields. The mitotic index of HeLa cells with 10 ug of EGF treatment is 8 mitotic figures noted per 90 high power fields. The mitotic index of cancerous cells with zero EGF treatment is 22 mitotic figures noted per 60 high power fields. The mitotic index of cancerous cells with 10 ug of EGF treatment is 27 mitotic figures noted per 465high power fields.
I'm on D right now so I'll put that in when I'm done with it
Following are the solution to the given questions:
For question 1:
Whenever we look at Table 1 with malignant cells versus HeLa cells, you can see when both types of cells were treated with EGF, the number of cells rose. Table 2 shows that when HeLa cells were fed with 25 ugs of EGF, they generated the most cells.For question 2:
Whenever normal cells were treated with 10 ugs of EGF, their number grew by 33. Once cancerous cells were treated with 10 ugs of EGF, their number increased by 405 times. With such a concentration of 10 ugs of EGF, one may deduce that malignant cells multiply faster than normal cells.For question 3:
The mitotic index of HeLa cells with no EGF treatment is 11 mitotic figures per 73 high power fields. Its mitotic index of HeLa treated groups with 10 ugs of EGF is 8 mitotic figures per 90 high power fields.With no EGF therapy, the mitotic index of malignant cells is 22 mitotic figures per 60 high power fields. The mitotic index of malignant cells treated with 10 ugs of EGF is 27 mitotic symbols per 465 large power fields.For question 4:
We believe that EGG and HeLa cells interact with one another, causing HeLa cells to develop rapidly in test 2.Learn more:
