A student reads that sperm and egg cells contain 23 chromosomes each. The height of a human being is controlled by multiple genes and alleles, which are present on the chromosomes found in each egg and sperm cell. When an egg and sperm cell fuse, they form a new cell containing 46 chromosomes with all of the genes and alleles necessary to determine height. This new cell further divides and develops into a human being.
Height in a human being is determined by the sets of ________(1)_______ obtained from _______(2)_______.
(1) workouts
(2) binary fission
(1) genes found on telomere
(2) just the male parent
(1) genes found on chromatid
(2) just the female parent
(1) genes found on chromosomes
(2) each parent
To study mitosis, a student places a garlic clove in water. After five days, the student observes roots growing from the clove. The student cuts a piece of the root and observes it under a microscope. The root tip has many cells with each under a different stage of mitosis.
What can the student conclude from the study?
Water stops the process of mitosis in garlic root tips.
Root tips switch from meiosis to mitosis when cut.
Plant cells undergo mitosis at high temperatures.
Mitosis helps in the growth of the plant parts.

Annette inherited 100% of her hair color genes from her mother.
Annette inherited 100% of her hair color genes from her father.
Budding and binary fission are both forms of asexual reproduction in one-celled organisms. What is known about the daughter cells produced as a result of the two processes?
Repiration ensures that they have half of the genetic information from the original parent cell.
Respiration ensures that they are identical to one another and to the original parent cell.
Mitosis ensures that they have half of the genetic information from the original parent cell.
Mitosis ensures that they are identical to one another and to the original parent cell.
The image shows two modes of reproduction.
Which statement is correct about the modes of reproduction shown in the image?
Mode 2 produces a zygote through the process of fertilization.
Mode 2 produces offspring identical to their parents.
Mode 1 produces offspring identical to their parents.
Mode 1 can produce offspring more rapidly than Mode 2.
Which statement accurately describes how genetic information is transferred during meiosis?
Meiosis creates two daughter cells that have identical genetic information to the parent cells.
Meiosis creates four daughter cells that have identical genetic information to the parent cells.
Meiosis creates two daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates four daughter cells that have half the number of chromosomes that are present in the parent cells.
Domestic cats transfer their genetic information to their offspring by meiosis. If a kitten has 38 chromosomes, how many chromosomes does the kitten inherit from its mother?
38 chromosomes
30 chromosomes
19 chromosomes
12 chromosomes
Which statement correctly describes a difference between asexual and sexual reproduction?
Asexual reproduction in organisms takes longer than sexual reproduction due to the time required to find a mate.
Asexually reproduced offspring have the same amount of genetic information as the parent, while sexually reproduced offspring have half as much genetic information as a parent.
Asexually reproduced offspring have less variety in their genetic information than sexually reproduced offspring.
Asexually reproducing organisms do not have DNA, while sexually reproducing organisms have DNA.
Examine the model.
Which process is shown in the model?
mutation
mitosis
metabolism
meiosis
What would likely happen if a multicellular organism no longer performed mitosis?
The organism would die as it is no longer able to replace damaged cells
The organism would adapt to function without the use of cells.
The organism would rely on gaining cells from other nearby organisms.
The organism would generate new cells only by the process of meiosis.
A child observes yeast cells under a microscope, as shown.
What can the child infer about yeast from the observation?
Yeast undergo sexual reproduction to produce offspring that are different from the parent.
Yeast undergo asexual reproduction to produce offspring that are identical to the parent.
Yeast undergo sexual reproduction to produce offspring that do not grow or change.
Yeast undergo asexual reproduction to produce offspring that do not use energy.
Organisms in nature reproduce to multiply their species. Which organism creates offspring through sexual reproduction?
Sea horses are types of fish that mate for life with the same partner.
Amoebas are single-celled organisms that can divide every 48 hours in optimum conditions.
Salmonella is a bacterium that can invade human cells and rapidly generate copies of itself.
Volvox is a type of green algae made up of identical cell groups called colonies.
A female parent snail with a striped shell and a male parent with no stripes produce five offspring, as shown.
Which statement best explains the reason for variation among the offspring?
In sexual reproduction, the male parent passes its genes to male offspring, and the female parent passes its genes to female offspring.
In sexual reproduction, offspring inherit genes from both parents, and each offspring has a new combination of traits.
In sexual reproduction, only the female parent passes genes to the offspring.
In sexual reproduction, only the male parent passes genes to the offspring.
In sexual reproduction, how do parents pass on traits to their offspring?
The genetic material from the male parent influences internal structures, and the genetic material from the female parent influences external structures in the offspring.

Each parent contributes one-quarter of the genetic material present in the offspring.
Each parent contributes one-half of the genetic material present in the offspring.

What is an advantage that asexual reproduction has over sexual reproduction?
Asexual reproduction allows offspring to be more adaptable to the environment.
Asexual reproduction results in offspring that are larger in size than the parent.
Asexual reproduction results in genetic diversity among offspring.

Which statement describes why eye color is an inherited trait?
It changes as a child grows to become an adult.
It depends on the amount of vitamin A in the diet.
It is passed from the parents to the offspring.
It depends on the color of light entering the eye.
What is a disadvantage for organisms that reproduce asexually rather than sexually?
The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.
