you guys should put an answer place i need it for my homework
What else can I help you with?
When population change over time has occurred?
Population change over time occurs due to a combination of factors such as births, deaths, migration, and natural disasters. These factors influence the growth or decline of a population, resulting in shifts in demographics and population size. Understanding patterns of population change is important for policymakers to plan for future resource allocation and infrastructure development.
What is this an example of Microevolution?
An example of microevolution could be the change in beak size in a population of finches over a few generations in response to changes in food sources. This change is driven by genetic variations being passed on to offspring and natural selection acting on those variations within a specific population, resulting in an adaptation to the environment.
Mutations are important for evolution because they .?
Mutations are very important for evolution today because they usually lead to the genetic changes in a given gene pool. They also allow the species to change with the environment.
How does vaiations form the basis of evolution?
Variations are random genetic differences that arise in a population. These variations can lead to differences in physical traits or behaviors. Over time, natural selection acts on these variations, favoring those that are advantageous for survival and reproduction. This process leads to the gradual change of species over generations, which is the basis of evolution.
What type of genetic change is most important for evolution?
Mutations are the most important type of genetic change for evolution. Mutations create genetic variation within a population, which is the raw material for natural selection to act upon, driving evolutionary change.
Why variations are important to understanding change in population over time?

What statement best describes temperature variations?
Temperature variations refer to changes in temperature over a period of time. These variations can occur on a daily, seasonal, or long-term basis due to factors such as weather patterns, climate change, and geographic location. Understanding temperature variations is important for predicting weather patterns and assessing the impact of climate change.
How do seasonal variations affect population and ecosystem?
Yes. Seasons can change the size of populations

Why is knowing the tilt of the earth's axis important?
Knowing the tilt of the Earth's axis is important because it causes the change in seasons. This tilt is responsible for the variations in sunlight and temperature differences that create summer and winter. Understanding the tilt helps in predicting climate patterns and agricultural seasons.
Mutations are important for evolution because they .?
Mutations are very important for evolution today because they usually lead to the genetic changes in a given gene pool. They also allow the species to change with the environment.
What three things do you need to know to identify a population?
To identify a population, you need to know the specific characteristics that define it, such as the species or group being studied. Additionally, understanding the geographic boundaries where the population exists is crucial. Finally, knowledge of the time frame for the study is important, as populations can change over time due to various factors.
What shapes Romanias population change?
The most important are emigration and the decline of births.
What best describes temperature variations?
Temperature variations refer to changes in temperature levels over a specific time period in a specific location. These variations can occur due to various factors such as daily cycles, seasonal changes, weather patterns, and global climate change. Understanding temperature variations is crucial for studying climate trends, weather patterns, and their impacts on ecosystems and human activities.
What are population dynamics?
The ways in which a given population's numbers grow and shrink over time, as controlled by birth, death, and emigrationThe changes in populations through time are known as population dynamics.
What does Population change mean in geography terms?
to find the population change, you subtract the natural increase of a place from the net migration to get the populatiopn change. it shows the change in that place's population over the last time
