Faunal Succession—The principle of faunal succession, also known as the law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances.
Original Horizontality—The Principle of Original Horizontality states that layers of sediment are originally deposited horizontally under the action of gravity. It is a relative dating technique. The principle is important to the analysis of folded and tilted strata.
lateral continuity—The principle of lateral continuity states that layers of sediment initially extend laterally in all directions; in other words, they are laterally continuous. As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous.
Superposition—Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured.
Answer:
b. the bottleneck effect.
Explanation:
The bottleneck effect occurs when a population's size is reduced for at least one generation. This will result in a very reduced genetic variation, which can lead to further adaptation problems.
The Founder effect has its similarities (in terms of the resulting reduced genetic pool) with the bottleneck effect, BUT it occurs when a new colony is started by a few members of the original population.
The Hardy-Weinberg equilibrium is a principle in population genetics that states that the genetic variation in a population will remain constant from one generation to the next IF certain conditions are present (no migration, aleatory mating, among others), so this is not the answer.
Genetic drift (refers to the change in the frequency of an existing gene variant in a population due to random sampling of organisms, so it is not the answer.
The correct answer is C. Prevention of eating disorders involves weighing often.
Explanation:
Eating disorders include multiple disorders that involve unhealthy eating habits as well as thoughts and emotions related to them. Individuals who suffer from these disorders constantly worry about their weight and appearance or have an unhealthy relationship with food, for example, individuals with anorexia or bulimia tend to believe they are "fat" even if they had low weight.
Due to this, weighing often is not a way of preventing eating disorders as this behavior just supports an unhealthy obsession with weight and appearance that can lead to eating disorders, instead, a balanced diet should be promoted and risk factors such as depression, anxiety, low self-esteem, etc should be addressed. Thus, the false statement is "Prevention of eating disorders involves weighing often".
In my opinion, it always depends on the partner how they are going to maintain their healthy relationship.
But for my opinion, here are the top 3 ingredients for a healthier relationship:
1. Communication - it is always important that you and your partner are being open with each other and being honest
2. Trust - trust is one of the most important and essential ingredients of healthy relationships
3. Commitment - how can you be in a healthy relationship if you are not commited?
