<span>1. the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
2. It depends on the unit of the ratio 6:1. If it is in cm1, 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 smaller cell has a better surface area to volume ratio, which means it is more efficient.</span>
Answer:
D.
Explanation:
Improper dosage, poisoning, improper labeling, are all typical problems.
Answer:
The smaller object will move at 30 m/s
Explanation:
From the principle of conservation of linear momentum,
Momentum of objects before collision = momentum of objects after collision.
![m_{1}v_{1} + m_{2}v_{2}=m_{1}v_{3}+m_{2}v_{4}](https://tex.z-dn.net/?f=m_%7B1%7Dv_%7B1%7D%20%2B%20m_%7B2%7Dv_%7B2%7D%3Dm_%7B1%7Dv_%7B3%7D%2Bm_%7B2%7Dv_%7B4%7D)
where
are the masses and velocities of the objects 1 and 2 respectively before collision.
![40\times 20 + 20\times 10 = 40\times 10 + 20\times v_{4}](https://tex.z-dn.net/?f=40%5Ctimes%2020%20%2B%2020%5Ctimes%2010%20%3D%2040%5Ctimes%2010%20%2B%2020%5Ctimes%20v_%7B4%7D)
![1000= 400 + 20v_{4}](https://tex.z-dn.net/?f=1000%3D%20400%20%2B%2020v_%7B4%7D)
![v_{4}=30m/s](https://tex.z-dn.net/?f=v_%7B4%7D%3D30m%2Fs)
Hence, the object will move at 30 m/s
Sound is directed down the ear canal to the ear drum, and then via the tiny middle ear bones (the smallest bones in the body) to the inner ear, which houses the sensory organ of hearing. This organ rests on a membrane that vibrates selectively to different sound frequencies, and so acts as a sound filter, which sorts sound frequencies into groups. High frequencies produce maximal vibrations at the beginning of the coiled inner ear, and low frequencies do the same at the other end.
Answer:
Nucleus
Explanation:
In a eukaryotic cell, these instructions are located in the nucleus.
