What are the three types of variation?
The three types of variation are genetic variation, environmental variation, and genotype-environment interaction. Genetic variation refers to differences in DNA sequences among individuals, while environmental variation is differences in traits caused by external factors. Genotype-environment interaction occurs when the effect of genes on traits depends on the environment.
What are the types of variations?
There are 2 types of variation: Continuous and Discontinuous. Continuous: Has slight differences that grade into each other. Usually has quantitative/measurable characteristics. e.g Human height/weight... Discontinuous: It has discrete differences which have a clear cut- they do not merge into each other. e.g. human blood...
What is the science definition for Variation?
Variation refers to differences or diversity among individuals within a population, species, or group. It can be caused by genetic, environmental, or developmental factors and plays a significant role in adaptation, evolution, and natural selection.
What causes most heritable differences?
Most heritable differences are caused by variations in DNA sequences, such as single nucleotide polymorphisms (SNPs) or insertions and deletions. These variations can affect genes and their expression, leading to different traits or characteristics being passed from parents to offspring. Environmental factors can also play a role in gene expression and further contribute to heritable differences.
The infections of the body are caused by what?
Infections of the body are caused by pathogens such as bacteria, viruses, fungi, and parasites. These pathogens can invade the body and multiply, leading to symptoms of infection. Factors such as a weakened immune system, poor hygiene, and environmental conditions can also contribute to the development of infections.
Which scientist became famous for telling the world about the environmental harm caused by DDT?
Rachel Carson, an American marine biologist, is credited with bringing attention to the environmental harm caused by DDT in her book "Silent Spring" published in 1962. Her work raised awareness about the negative effects of pesticides on ecosystems and wildlife, sparking the modern environmental movement.
Which of the fllowing is caused by differences in ocean water density?
Differences in ocean water density are primarily caused by variations in temperature and salinity, leading to ocean currents. These density differences drive the global thermohaline circulation, also known as the "ocean conveyor belt," which plays a crucial role in regulating climate and distributing heat across the planet. Additionally, these differences can lead to phenomena such as upwelling and downwelling, affecting marine ecosystems.
What is an example of an environmental problem caused by chemicals?
Televisions that contain dangerous chemicals being thrown in landfills.Apex
Are deep currents caused by differences in pressurre?
All currents are caused by differences in pressure.
Are all physical differences caused by genetic differences?
No. Some can be caused are caused by nurture: health - including diet and diseases.
What is environmental imbalance?
Environmental imbalance happens when anything alters the function of an ecosystem. Ecosystems naturally maintain global environmental balance. Deforestation, soil erosion, and greenhouse gases are some of the causes of environmental imbalance.
What is developmental variation and environmental variation?
Environmental variation is a change that occurs in your, or anyone's, appearance caused by the environment. Examples are: skin color (like having a tan), a scar, the ability to play an instrument, ability to speak different languages, etc...
Are environmental disasters and natural disasters similar to each other?
Environmental disasters are usually caused by human activities, leading to environmental damage, while natural disasters are caused by natural processes such as earthquakes or hurricanes. Both types of disasters can have detrimental effects on ecosystems and human populations, but they differ in their origins and underlying causes.
The movement of material due to differences in density that are caused by differences in temperature is called what?
The movement of material due to differences in density caused by differences in temperature is called convection.

Is chickenpox caused by genetic or environmental factors?
Environmental. It's a virus.
How is extreme wind caused?
Its caused ok differences in air pressure
