Answer:
of diffusion
Explanation:
Particles travel along a concentration gradient without requiring energy. This indicates they transition from an area of high concentration to one of low concentration. This process takes place across a semi-permeable membrane, such as the cell membrane, via simple diffusion.
Answer:
Sexual reproduction requires two parents and results in offspring with unique genetic compositions. In the process of sexual reproduction, two haploid gametes fuse during fertilization to form a diploid zygote. The mechanism of meiosis is what generates gametes.
Explanation:
Answer:
Explanation:
The pH formula is given by
![pH = -[log H+]\\](https://tex.z-dn.net/?f=pH%20%3D%20-%5Blog%20H%2B%5D%5C%5C)
It's also stated that each pH unit indicates a tenfold change in hydrogen ion concentration.
For lemon juice with a pH of 2, the hydrogen ion concentration is
While for pure water, which has a pH of 
, the concentration is
Thus, the concentration of H+ ions in lemon juice is 
times greater than in pure water.
