R-organisms are usually bellow carrying capacity (<span>the maximum size of some population that can survive in the given environment)</span>. Those organisms are small and produce a great number of offspring. However, their life expectancy is short and many individuals die within a short time. Because of the high rate of death, they do not live long enough to reach their carrying capacity. Their life span is short, so even if predators were removed from the population, it would not be expected they will reach their carrying capacity.
Answer:123456Which statement best explains the main conflict and resolution in "How a Cat Played Robinson Crusoe"?
The cat is abandoned on an island. She adapts to the wilderness and survives until her family returns.

The cat faces many adversaries, including rats and owls. However, she persists and is able to overcome each.
The cat learns how to hunt. She does not starve to death on the island.

Answer:
CRISPR-Cas9 is a DNA modification technique derived from a bacterial defense mechanism.
This breakthrough innovation allows the deletion and insertion of genes in a simple, fast and efficient way, much like "DNA scissors".
The CRISPR-Cas9 method is increasingly used in laboratories because it has several advantages over the DNA cutting enzymes developed before it.
First advantage, it is much easier to use (compared to other gene-editing tools). It has already allowed several teams of researchers to target several genes at once, including in human cells.
Other major advantages resulting from the simplicity of the system: its speed and its low cost. The CRISPR-Cas9 method takes only a few days (instead of a few months) and is at least ten times less expensive than those used before.
CRISPR-Cas9 is therefore a tool of disconcerting ease to modify the genome of many types of cells (to produce a protein for example), in bacteria, plants, animals and perhaps one day in humans.
Because the higher the food chain gets, the less energy is being transferred , therefore, there are less organisms at the top of the food chain.
