Answer:
1. As the cell size increases, the ratio of surface area to volume DECREASES
2. It depends on the unit of the ratio 6:1. If it is in cm−1, then it means that it is similar to a cell of size 1 cm^3, which is normally too big to get materials from the surface
.
3. A Small cell has a large surface area/volume ratio and therefore can exchange molecules with it's external environment rapidly. So, Here cell with ratio 6:1 is smaller and have ability to better transportation across it's membrane as compared to other cell with ratio 3:1
HOPE THIS HELPS!!!
Your answer would be C because A affects the natural environment and can cause harm to it, B would affect the surrounding animal population and cause imbalances in biodiversity if they are not able to eat the foods they are used to, and D is not much of a benefit since you are losing the flavor that is naturally in the plants.
The second law of thermodynamics states that not all of the energy is used because some of the energy is lost in the form of heat. The lost heat energy is an unusable form of energy, and it causes an increase in the entropy of the universe. Thus, no energy transfer process is efficient due to the loss of energy.
Answer:
C. The universe coalesced into one solar system after the Big Bang.
Explanation:
This is true because, since she is writing about Big Bang theory, she would have to include how the universe was able to expand to one solar system made up of different planetary bodies. This explanation would help someone reading her writeup to understand what the Big Bang theory is all about.
Answer:
B. Performing a larger number of experimental trials makes the results more dependable.
Explanation:
Every measurement has uncertainty.
If the uncertainties are random, the more measurements you make the more likely you are to mess up.
