It is important to use several sources when conducting research because it allows for a broader understanding of the topic. Using multiple sources helps to ensure that the information gathered is accurate and provides diverse perspectives and opinions. This can lead to a more comprehensive analysis of the topic being researched.

lack of advantageous traits
The gene pools of small populations are reduced compared to those of larger populations because of the bottleneck events. When a population undergoes a bottleneck event, such as a natural disaster or a disease outbreak, a large percentage of the population is eliminated, reducing the genetic diversity of the population. This loss of genetic diversity can result in inbreeding or the lack of advantageous traits, which can further decrease the gene pool of the small population. Additionally, in small populations, there may be a lack of suitable mates, which can also limit genetic diversity.

It has temporarily increased, so disadvantageous traits are more likely to be passed on.
It has temporarily decreased, so disadvantageous traits are less likely to be passed on.
It has temporarily decreased, so disadvantageous traits are less likely to be passed on.
It has temporarily decreased, so disadvantageous traits are more likely to be passed on.
A bottleneck event reduces the gene pool of a population, thereby decreasing genetic diversity. So, the correct option is: It has temporarily decreased, so disadvantageous traits are more likely to be passed on.
Which information helps scientists determine the survival probability of a population?(1 point)
Responses
the feeding habits of an individual in the population
the feeding habits of an individual in the population
the number of offspring of an individual in the population

the existence of natural selection in the population

the level of genetic variation in the population
The level of genetic variation in the population helps scientists determine the survival probability of a population. Genetic diversity is necessary for a population to adapt to a changing environment and withstand negative impacts. A population with high genetic diversity is better equipped to handle environmental changes, such as disease outbreaks, climate changes, and habitat destruction. Therefore, understanding the level of genetic variation in a population is essential for assessing their survival probability.
What relationships exist among reasoning, evidence, and explanation?(1 point)

Reasoning is used to connect the evidence and the explanation.
Evidence is used to connect the explanation and the reasoning.
Reasoning is used to connect the evidence and the explanation. In scientific inquiry, evidence is gathered and analyzed to support or refute a claim. Reasoning is then used to connect the findings of the evidence with a logical explanation of the phenomenon being studied. Without reasoning, the evidence would remain unconnected and the phenomenon unexplained, and without evidence, the reasoning and explanation would lack support and cannot be verified. Hence, both reasoning and evidence are necessary to develop a coherent and persuasive explanation.

less likely that some of the members will have traits that let them survive and reproduce.
less likely that most of the members will have traits that let them survive and reproduce.
More likely that some of the members will have traits that let them survive and reproduce. The variation in traits allows the individuals to have different advantages or disadvantages depending on the environment and the pressure that is exerted on the population. Some traits can help individuals to adapt and survive, and others may be detrimental to the population. By having a variety of traits, a population is more likely to have individuals with traits that give them an advantage to survive and reproduce in different environments, which increases the likelihood of overall survival of the population.

Living things with traits that are a good fit to their environment are more likely to survive and reproduce. If an organism's traits are well-suited to the environment they live in, they will be better able to obtain resources such as food, water, and shelter, and defend against predators. This increases their chances of survival and reproductive success. Over time, natural selection favors individuals with advantageous traits, leading to the adaptation of the organisms to their environment and an increase in the frequency of those traits. Therefore, organisms with traits that are a good fit to their environment are more likely to survive and reproduce.

Consider the following scenario:
A scientist is analyzing one bird population. There is a large amount of variation in size in the population. There are also predators that eat these birds. After collecting evidence on three types of birds (small, medium, and large), the scientist discovers that the large birds are less likely to be killed. The only major genetic difference is the size of the birds. The colors and behaviors of the large birds are the same as those of the small and medium birds.
Using reasoning skills, which is the most credible explanation for what is contributing to this higher rate of survival?

The large birds may be the hardest for predators to see.
The large birds may be the largest group in the population.
The most credible explanation for what is contributing to this higher rate of survival among the large birds is that the large birds may be the hardest for predators to attack. Larger birds may have stronger beaks and talons, making them better able to defend themselves against predators. Their size may also make them more difficult for predators to catch and kill. This is a logical explanation based on the evidence provided, which suggests that the only major difference between the birds is their size. Therefore, the most credible explanation is that the larger birds have a greater chance of survival due to their physical size.
