All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -
makes its own food
is unicellular
live in a marine habitat
reproduces asexually
Ovuluation is the process in which
sperm is released
ovaries are released
egg cells are released
Sperm cells contain
23 pairs of chromosomes
46 chromosomes
23 chromosomes
None of the options
The diagram below represents the life cycle of a butterfly.
This life cycle represents the process of
separation from parent
asexual reproduction
metamorphosis
extinction
The diagram below represents an event in human reproduction.The numbers in the drawing represent the number of
genes
chromosomes
cells
DNA
Why is an organism that reproduces asexually genetically identical to its parent?
All of the offspring’s genes came from the parent.
All of the offspring’s genes mutated to look like the parent’s genes
The offspring inherited only half of the parent’s genes.
The offspring in
Identify the sexual reproductive process represented at A
Mutation
Metamorphosis
Fertilization
Ovulation
These rabbits all came from the same litter with the same parents. One of them has longer ears than the others. Neither parent has the gene that causes longer ears. Identify the process that might cause the appearance of this new trait in the offspring.
asexual reproduction
sexual reproduction
Migration

The diagram below represents a plant. One plant structure is labeled X. The diagram below represents a plant. One plant structure is labeled X.
produce seeds
attract insects
support the plant

The diagrams below represent reproduction in two different types of organisms, amebas and birds. Explain why the bird offspring will differ from its parents more than the ameba offspring will differ from its parent.
The ameba has more mutations
The bird reproduced sexually and the ameba reproduced asexually
The ameba reproduced sexually and the bird reproduced asexually
The birds are identical to only one of it's parents
The diagram represents reproduction and cell division in a sea urchin (animal) in stages labeled A through F. When a sea urchin reproduces, the female sex cell and the male sex cell unite to form a cell called a zygote. The zygote divides several times in a matter of hours.
Between which two consecutive stages did fertilization occur?
A and B
B and C
C and D
After f
