Briefly describe two ways in which the Hardy-Weinberg equation can be used to get information about a population.

Answers

The Hardy-Weinberg equation can be used to determine probable frequencies of genotypes in a population. It can also track changes of genotypes from generation to generation

Answer:

The Hardy-Weinberg equation can be used to gather valuable information about a population in the following two ways:

1) Estimating allele frequencies: The Hardy-Weinberg equation allows scientists to estimate the frequency of specific alleles within a population. By comparing the observed frequencies with those predicted by the equation, researchers can determine if the population is in genetic equilibrium, meaning that the allele frequencies are stable and not evolving over time.

2) Identifying evolutionary forces: If a population deviates from the expected Hardy-Weinberg equilibrium, it suggests that one or more evolutionary forces, such as natural selection, genetic drift, gene flow, or mutation, are at play. By analyzing these deviations, scientists can gain insights into the factors influencing the genetic makeup of the population and better understand the evolutionary processes driving changes in the population's gene pool.

Which is one effect that would most likely result from a tsunami?
death
drought
extinction
genetic change

Answers

Death - A tsunami involves an ocean which wouldn’t cause a drought because the mass of water extinction the tsunami as a whole wouldn’t destroy every living thing on earth but cause a large death toll genetic change wouldn’t occur

One of the consequences of tsunami happening in a place would be death and destruction of biodiversity.

What is a tsunami?

A tsunami is a natural disaster caused by multiple waves in water bodies that send large volumes of water inland.

The sudden displacement of water with a large force destroys lives and properties on land, especially the coastal lands.

Thus, one of the surest effects of tsunamis is death.

How could a scientist use the scientific method to learn more about the Cretaceous era?

Answers

First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.

After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.

After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.

After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".

At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.

The Cretaceous period was a prehistoric period that took place between about 140 and 60 million years ago. If a scientist wanted to use the scientific method to learn more about this time, he should implement the following steps:

Identify an unresolved issue or problem that you would like to address. Make a hypothesis that raises answers to these questions or problems. Carry out a series of investigations and experiments dedicated to verifying the hypotheses raised. Finally, having verified the hypotheses, propose a law or rule for the investigated questions.

Read the following excerpt. Sarah looked at her brother again, waiting for some sort of response. Surely, he had not resigned himself to this situation.
