Cells
What are Cells?
Cells are the basic units of structure and function in living things.
What is the chemical property of matter?
They include reactivity, flammability, and the ability to rust.
What are mutations?
Mutations occur when a DNA gene is damaged or has changed.
Valence electrons help determine the chemical properties of a element.
What is photosynthesis?
The process in which green plants use sunlight to make their own food.
What is the Cell theory?
The Cell theory is a widely accepted explanation of the relationship between cells and living things.
Can water stay liquid below zero degrees Celsius?
Yes, water can stay a liquid.
What does dominant VS recessive mean?
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
What is a chemical bond?
A chemical bond is the force of attraction that holds atoms together as a result of the rearrangement of electrons.
What is the photosynthesis equation?
6 CO2 + 6 H2O ------ C6H12O6 + 6O2
Which cellular structures are found in plant cells but not in animal cells?
Chloroplasts, Cell wall, Vacuole.
What are the two types of Mixtures?
Heterogeneous mixtures and Homogeneous mixtures.
What is DNA?
The material that contains all the information about how a living thing will look and function.
How many valence electrons do atoms like to have?
8 valence electrons.
What is the role of chlorophyll?
Chlorophyll's job in a plant is to absorb light—usually sunlight.
Which living organism has the most cells?
What eventually happens to a gas if pressure is increased?
It condenses
What is a gene?
The information that determines your traits.
How many protons does lead have?
82 protons.
Why can photosynthesis not occur at very high temperatures?
Photosynthesis cannot occur at very high temperatures because enzyme activity is lower.
What is the most complex level of the cell organization?
Organism
What is a disadvantage of using hydrogen as fuel?
There are very few hydrogen filling stations.
What are inherited traits?
An inherited trait is traits are passed from parent to offspring.
What is the Electron Dot Diagram?
An electron dot diagram includes a symbol for the elements dots.
Can photosynthesis occur at night?
Plants can perform photosynthesis at night only if they are provided with the artificial light of the corresponding wavelengths.
