holds the anther uP
FILAMENT
How many total chromosomes should a human have?
46 (23 PAIRS)
A process in which two parents collaborate to produce their offspring.
SEXUAL REPRODUCTION
the process where humans select organisms with desired traits to breed and produce offspring with those same traits
SELECTIVE BREEDING
life begins as a ______________, a single cell that carries half the DNA of each of its own two parents.
ZYGOTE
function is to produce and release pollen, which contains the male sperm cells needed for plant fertilization.
ANTHER
The base in DNA that is complementary to Adenine
THYMINE
Both multicellular and unicellular species exhibit; There will be no gamete fusion or change in the number of chromosomes as a result of this operation. It will inherit the same genes as the parent, except for a few circumstances where a rare mutation may develop
ASEXUAL REPRODUCTION
piece of evidence that explains the Evolutionary Theory by studying the distribution of organisms over the earth using patters that correspond with the separation of land masses
BIOGEOGRAPHICAL EVIDENCE
purpose of mitosis?
process where a single parent cell divides to make two identical daughter cells.
the stalk that supports the stigma and connects it to the ovary. major function is to assist with fertilization by being the location where pollen tubes travel to deliver sperm cells to the egg.
STYLE
a change in the DNA sequence of an organism
MUTATION
type of asexual reproduction where he parent body splits pieces here, which grow into a new person.
FRAGMENTATION
mechanism of evolutionary theory where certain alleles from a population’s gene pool are lost due to random events. When this occurs, a trait that was once present in a population disappears.
GENETIC DRIFT
phase of mitosis where chromatids separate and move to opposite ends of the cell.
ANAPHASE
part of the female reproductive system of a flower. It is found in the center of a flower and helps to collect pollen.
STIGMA
A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid.
CODON
Bacterium undergoes this type of asexual reproduction, in which the cell and nucleus divide into two.
BINARY FISSION
mechanism of evolutionary theory where genetic diversity is lost when a small colony separates from the original larger gene pool.
FOUNDER EFFECT
Phase of mitosis where two new nuclei form around each set of chromosomes.
TELOPHASE
function to protect the developing bud. They act as a protective layer, safeguarding the delicate inner parts of the flower
SEPALS
These are the building blocks of genes and make up the “rungs” of the ladder in a DNA molecule.
Hydras reproduce through this type of asexual reproduction
BUDDING
piece of evidence that explains the Evolutionary Theory by studying the structure and function of macromolecules that are vital for life
MOLECULAR EVIDENCE
phase where he cell grows in size and replicates its DNA to prepare for cell division. Makes the proteins needed for cell division and makes copy of its DNA.
INTERPHASE
