Answer:
B)speciation
Explanation:
Speciation is the term used to refer to the division of a lineage that produces two or more different species. In a nutshell, we can say that this is the process of the emergence of a new species, and the crucial event for this to happen is reproductive isolation. This reproductive isolation impedes the gene flow, therefore, obeying the biological concept of species, we say that a new species has emerged.
An example of speciation is shown in the question above, where a volcano separated two species and left them in reproductive isolation. The result of this was that two populations became so different from one another that they became unable to breed, creating new species.
B is the correct answer for e2020
Answer:
B. during the S phase of the cell cycle
Explanation:
DNA replication occurs during the S phase of cell cycle in which the genetic content of a cell double folds so that when the cell divides into two equal halves one set of the genetic content could be passed on to the daughter cell. S phase is also known as synthesis phase. S phase is the phase of cell cycle which is in between G1 phase and G2 phase and the duration of S phase is around eight hours.
The answer is increased. Hope this helped.
In a population, when the birthrate becomes higher than the death rate, the population’s growth rate is increase.
A population is a group of individuals of the same species that live in a particular area or number of people living in the same area, for example, a city population means the number of people living in that city.
Population growth is the change in a population over time. It can be increasing or decreasing, depend on some factors. Four factors that affected the population:
The population's growth rate increase when the birth rate is higher than the death rate, or the emigration is lower than the immigration. When the death rate is higher than the birth rate or the emigration rate higher than immigration rate the population's growth is decreased. The population growth is a result of a combination of natural increase and migration flows.

Every slice of the bread, contains a number of blister like pores. These blister like pores suggests that the air or some gas might be present there. In case, the bread has no air, the surface of the bread must be smooth rather than rough.
The bread is formed by the fermentation of the sugar molecules present in the dough with the help of yeast. These blisters like structure on the bread is present due to the gas produced during fermentation.
Explanation:
Because we always seek to make sense of any perceived stimulus to better understand the reality that surrounds us and act before it. Through perception we process information from the senses, with which the brain builds and tries to give meaning to those stimuli that reach it. However, each person captures, selects and organizes sensory stimuli differently and, therefore, arrives at different interpretations and responses when solving a problem, in which memory and experience also form a fundamental role. Thus, differences between perceptions help explain how people interpret the environment and why they behave differently in the same situation. For example, when we recognize a specific object, an action can be initiated, in which a motor activity is propitiated in response to that recognition, and which can be different in each person.
Answer:
Name and Title
Include your name, instructor's name, date, and name of lab.
Objective(s)
In your own words, what was the purpose of this lab?
Hypothesis
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the investigations. You will investigate two different versions of the tree environment as it changes over time: light-colored bark and dark-colored bark. Be sure to list your hypothesis for each environment below.
Example: If I investigate the light-colored bark environment, then I will observe an increase in the light-colored peppered moths over time.
Hypothesis for the light-colored bark:
Hypothesis for the dark-colored bark:
Procedure
The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.
Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation.
Test variable (independent variable):
Outcome variable (dependent variable):
Data
You will investigate both environments. Record your data for each trial of that environment in the data charts below.

Conclusion
Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.
What caused the tree bark to become darker?
In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?
In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?
During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.
Explanation:
Evolution and natural selection is the process where organisms with characteristics that allow them to adapt to their environment reproduce more successfully. Writing about this can involve exploring real-life examples of evolution in action such as antibiotic resistance in bacteria, or changes observed in the Galapagos finches.
The subject 02.04 Evolution and Natural Selection in science refers to the process by which species adapt to their environment and change over time. Natural selection, first proposed by Charles Darwin, is the mechanism that drives this evolutionary change. It is the process where organisms with characteristics that allow them to better survive in their environment will reproduce more successfully.
Writing about this topic might involve exploring examples of evolution in action, such as antibiotic resistance in bacteria or the changes in beak shapes among Galapagos finches. For example, you could write about how bacteria resistant to antibiotics have a survival advantage and are more likely to reproduce, spreading their resistance to future generations. This is evolution by natural selection in action.
Perhaps consider the impact of human activities on evolution, such as how pesticide use in agriculture has driven evolution in pests. Be sure to include how natural selection can only occur if there is variation within a species, if that variation is heritable, and if different genotypes have different reproductive success.
