Total questions: 39
Worksheet time: 22mins
What happens during meiosis?
two sex cells combine
chromosome pairs separate and are distributed into new sex cells
each sex cell copies itself to form four new chromosomes
chromosome pairs remain together when new sex cells are formed
When sex cells combine to produce offspring, each sex cell will contribute
one fourth the number of chromosomes in body cells
half the number of chromosomes in body cells
the normal number of chromosomes in body cells
twice the number of chromosomes in body cells
Cloning results in two organisms that are
both adult mammals
produced from cuttings
genetically similar
genetically identical
What type of reproduction produces fungi that are different from either parent?
budding
asexual reproduction
sexual reproduction
dividing
Binary fission is the bacterial process of
asexual reproduction
obtaining food
producing energy
forming endospores
The process by which a new organism forms from the joining of an egg cell and a sperm cell is called
asexual reproduction
sexual reproduction
adaptation
budding
The joining of an egg cell and a sperm cell is called
stability
adaptation
asexual reproduction
fertilization

zygote
mutation
chromosome
cytoplasm
What is the process shown in this figure?
budding
cloning
regeneration
vegetative reproduciton

anaphase I
prophase I
anaphase II
telophase II

prophase I
anaphase II
metaphase II
A sea star has one of its arms break off. That arm grows into its own separate organism through ____________________.
sexual reproduction
regeneration
spindle fibers
chromosomes
In asexual reproduction, offspring are produced ___________________.
from one parent
from two parents
from 46 chromosomes
from 8 chromosomes
The process that produces haploid sex cells is __________________.
mitosis
fission
meiosis
interphase
If fission takes place every 20 minutes in some bacteria, then starting with one bacterial cell, how many bacterial cells would be produced in the span of 4 hours?
512
360
1024
4096
Hydra reproduce through ___________________, where the offspring grows from the body of the parent organism.
budding
DNA
thymine
mutations
Human reproduction involves which of the following?
body cells
sex cells
skin cells
mitochondria
What is the mathematical relationships between the number of chromosomes and the number of homologous pairs?
there is no mathematical relationship between the number of chromosomes and the number of homologous pairs
the number of chromosomes is related directly to the age of the organism, so the number of homologous pairs changes
there in only one chromosome in each homologous pair
there are one half as many homologous pairs as there are chromosomes
