False. Domestication is the process of selecting wild animals and CHANGING their characteristics to suit the needs of the producer/owner or breeder.
Answer:
a >c > b.
Explanation:
The buoyant force may be defined as the force that mainly opposes the immersed object weight. The buoyant force is greater at the bottom and acts on upward direction.
The buoyant force depend on the object of the volume and directly proportional to the volume. The buoyant force of elephant is highest as it has highest volume than skydiver and balloon has least volume and so the least buoyant force.
Thus, the answer is a >c > b.
Answer:
In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.
Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.
For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.
Some genetic mutations can be completely harmless, while others are life-altering. Mutations happen when DNA is copied incorrectly. This causes an irregularity in the DNA. Mutations are permanent changes to genetic material that can be passed on to offspring. These changes happen randomly and can occur in any type of gene. While some mutations are not harmful (hazel eyes, for example), many mutations have harmful effects on health.
