and answers)
Nucleus - answer Acts like the brain of the cell.
Helps control eating, movement and reproduction.
Cell Membrane - answer Holds all the cell
pieces/fluids inside the cell.
Mitosis - answer The process where a single cell
divides resulting in generally two identical cells -
each containing the SAME number of chromosomes
and genetic content.
Meiosis - answer Division of sex cells. - ME ME
Photosynthesis - answer Plants transform water
and carbon dioxide into carbohydrates using
energy from the sun.
Proteins - answer Building blocks call amino
acids. The building material for our skin, bones,
, muscles and tissues. Also acts as transporters of
important nutrients.
Fats - answer The body uses this as a fuel source
and is the major storage form of energy.
Dominant Alleles - answer Expressed in the
phenotype. Show their effect even if the individual
only has one copy of the allele. (Aa) (AA). Written
as a capital letter.
Recessive Alleles - answer The weaker allele.
Written as a lower case. Only show their effect if
the individual has two copies of the allele. (aa)
Genes - answer Made up of DNA. Carries the plans
for constructing cells, tissues, organs, and bodies.
Traits - answer Feature of an organism. AKA -
phenotype.
Natural Selection - answer The process where
organisms better adapt to their environment tend
to survive and produce offspring.
