What is photosynthesis?
Photosynthesis is how plants make food and oxygen using sunlight, carbon dioxide, and water.
Name two limited resources we get from earth?
Oil , Natural gas , Coal Also known as "fossil fuels"
What is DNA?
DNA is a molecule that carries genetic information and is made up of four chemical bases.
What is force?
Force is a push or pull which acts on an object.
What is the definition of Energy?
Energy is the capacity of a system or object to do work, or the ability to cause a change in matter.
What are the four things needed for photosynthesis?
Sunlight , Carbon dioxide , Chlorophyll and Water.
What is global warming?
where the earth's average temperature rises due to increased amounts of greenhouse gases
What is a gene?
A gene is a DNA segment that contains instructions for an organism's traits by producing proteins.
What unit is force measured in?
Force is measured in Newtons (N).
What are some common forms of energy? (Say at least 4)
Kinetic energy , Potential energy , Thermal energy , Electrical energy , Chemical energy and Nuclear energy.
What is the the word equation for photosynthesis
Sunlight
Carbon dioxide + Water --------> Glucose + Oxygen
Chlorophyll
Describe 2 possible effects of global warming?
Longer period of droughts and could cause wildfires
What is the definition of genetics?
Genetics is the study of genes and how they determine the traits of living organisms.
What are balanced forces?
Forces that are equal in size and opposite in direction.
How is energy related to work?
When you do work to move an object, you change the object's energy.
What is pollination? What are the 2 types of pollination?
Pollination is the transfer of pollen from the male part of a flower to the female part, leading to fertilization. The two types are self-pollination and cross-pollination.
How are igneous rocks formed?
when hot, molten rock crystallizes and solidifies.
How does genetic inheritance work in humans?
Genetic inheritance in humans is the passing of traits from parents to offspring through DNA during reproduction.
What can force change?
It changes the speed, shape , direction of an object.
What is the law of conservation of energy?
Energy cannot be created or destroyed, only transferred or converted from one form to another.
What does the ovary eventually develop into?
The ovary of a flower develops into a fruit that protects and helps disperse the seeds after fertilization occurs.
Give 1 example of sedimentary rocks
Sandstone , limestone
What are genes and how do they determine our traits?
Genes are segments of DNA that determine our traits by encoding proteins.
What is a moment , its formula?
A moment is the turning effect of a force
Moment = force X distance
