lessons 1-3 science

sex cells have blank chromosomes

23

you have blank pairs of homologous chromosomes

23

in your body so you have blank chromosomes

46

how many chromosomes in humans should be in each diploid cell after mitosis

46 chromosomes or 23 pairs

genetic material or blank is found in all living organisms

DNA

chromosomes are of blank and contain your blank

DNA and genes

what is a chromosome made of

DNA and proteins

in mitosis the new cell has an blank of genetic material of the original cell

Full set

what is meiosis

a type of cell division that makes sex cells

what is an example of organisms that reproduce like eukaryotic organisms (single celled)

amoebas

since the offspring is identical to the parent the reproduction is called

asexual

compare and contrast asexual and sexual reproduction

asexual: ex.; sea-stars regenerating, bacteria uses binary fission to split in 2 (prokaryotes), yeast uses budding which is when a child is and outgrowth on the parent which may fall of and be individual or stay like a coral. amoeba; not a he or shell, spore is a specialized cell that survives in harsh conditions: differences, faster more efficient, it can use mitosis, there's no diversity, not sexual, has one parent, offsprings are clones,;sexual; -2parents, offspring not identical to eachother and parent, variety, fertilization occurs when sperm and egg combine to form a zygote, it is a slower process and needs more energy, sex cells are called gametes

is DNA copied before or after cell division

before

in mitosis the cells that are created are

body cells that are identical to the parent

meiosis start out looking like mitosis DNA is blank and two blank cells are produced. However meiosis has two blank and results in blank cells each with blank the number of chromosomes.

copied, identical, divisions, 4,half

The rest of us are divided into two identical cells in blank

cytokinesis

what are differences and similarities between mitosis and Meiosis

difference; in mitosis there are diploid chromosomes which is 46 chromosomes in humans but in meiosis there are haploid chromosomes or 23 chromosomes in humans, the number of cells in mitosis is two and the number of cells and meiosis is four, in mitosis it divides wines and and me oh sis it divides twice, mitosis is used to replace body cells and sometimes used to reproduce but in meiosis it creates sex cells; similarities are that they both copy once

A body cel that has two pairs or sets of chromosomes is called

diploid

multicellular organisms body cells blank by mitosis

divide

females have Frank chromosomes and mail have blank and blank chromosomes

females have 2X chromosomes and males have one X and one y chromosome

another word for sex cells is blank which is blank

gametes which is an egg or sperm cells

DNA directs and organisms blank blank and blank

growth development and activities

multicellular organisms use mitosis for blank blank blank and blank

growth development so repair and reproduction

a cell with blank of the chromosomes is called haploid

half

sex cells have blank the number of chromosomes found in a body cell.

half

when chromosomes are paired up we call them blank chromosomes

homologous

at the end of mitosis there are two nuclei with blank genetic material

identical

The cell cycle is ordered steps to go through and repeat the three steps are

interphase mitosis and cytokinesis

describe what would occur if cells were in mitosis more than they were in interphase

it would cause an uncontrolled growth which causes cancer

which would have more serious outcomes if there was an error- meiosis it mitosis

meiosis - could cause birth defects

describe how mitosis is important for your body

mitosis helps your body Gralin developed repair and sometimes reproduce

23 chromosomes came from your blank and the other 23 chromosomes came from your blank

mom and dad

what is interphase

most the time the sellers in interface it is growling moving and interacting with the environment genetic material is copied and ready for the next stage

what are mitosis is four main stages

prophase metaphase anaphase and telophase

cell division also makes new cells to

replace damaged or old cells

Single cell organisms use mitosis to blank by cell division

reproduce

in eukaryotic or single celled organisms mitosis is used to

reproduce

in sexual reproduction blank cells join together

sex

what types of cells do not undergo mitosis

sex cells

in humans the blank chromosomes determine blank characteristics

sex, sexual

most pairs of chromosomes are the same blank and blank with one important exception

size and shape

DNI determines the blank an individual inherits and needs to live

traits

mitosis produces

two identical body cells

the result of sexual reproduction is called a

zygote
