Explanation:
Yes logs are made up of cells, Plant cells to be exact.
Answer:
Active Transport
Explanation:
Active transport is the process of transport of substances from region of their lower to that of higher concentration. Since the transport occurs against the concentration gradient, it is energy requiring process and needs input of energy to occur.
In given example, liver cells transports vitamins against the concentration gradient in energy dependent manner. Therefore, it is an example of "active transport".
Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction.
Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur.
Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.
