The passage of genetic instructions from one generation to the next is known as -
A. heredity
B. commensalism
C. traits
D. phenotype
Heredity is defined as the passage of genetic instructions from one generation to the next. Which of the following is NOT an example of these genetic instructions in humans?
A. Height
B. Skin color
C. Dimples

Jellyfish are soft bodied, free swimming, aquatic animals. They reproduce sexually by releasing
egg and sperm into the water. The egg and sperm unite in fertilization and create a new
jellyfish polyp. Which of the following best describes a jellyfish polyp?
A. The jellyfish polyp will be genetically identical to the parent jellyfish.
B. The jellyfish polyp will be a diverse combination of the parent jellyfish genetic material.
C. The jellyfish polyp will have twice as much genetic material as the parent jellyfish.
D. The jellyfish polyp will be genetically identical to its siblings.
Which of the following scenarios of reproduction is most likely to form uniform offspring?
A. Pollen from one flower pollinates an egg of another flower to produce seeds.
B. A female fish lays unfertilized eggs in a river, and the male arrives later to fertilize the eggs.
C. Spores are formed from two cells, each from individual fungi organisms.
D. An amoeba splits during binary fission into two separate cells.
Hydra reproduce by a process known as budding, as shown in the diagram below. This type of reproduction is This process is the formation of a new individual that is a clone of the parent.
A. sexual
B. sporulation
C. asexual
D. binary fission
What parts of a cell are most likely involved with inherited traits?
A. Chromosomes, genes, and vacuoles
B. Chromosomes, genes, and nucleus
C. DNA, genes, and mitochondria
D. DNA, nucleus, and cell membrane
Which of the following cell components are most involved in determining an organism's traits?
A. Chromosomes
B. Cytoplasm
C. Mitochondria
D. Chloroplast
Which of the following best explains why children usually look more like their siblings (brothers and sisters) than their friends?
A. They eat more of the same foods and drinks as their siblings.
B. They spend more time together over the years with their siblings.
C. They share many of the same genes from their parents with their siblings.
D. They share more of the same environmental influences with their siblings.
Some animal behaviors are listed.
These behaviors are innate because the behaviors are
A. performed by four different species.
B. learned from one or both parents.
C. observed only in certain environments.
D. performed without any previous learning experience.

It has acquired traits in response to its environment.
It has a lower mass of genetic material than offspring B.
It has the same genetic material as its parent.
It has half as much genetic material as its parent.
Daffodils can reproduce both asexually and sexually. How does a daffodil population benefit from reproducing sexually instead of asexually?
A. It can reproduce more rapidly.
B. It can pass favorable traits to all offspring.
C. It can increase the diversity of inherited traits.
D. It can eliminate unfavorable traits from the gene pool.

A. fission
B. budding
C. fragmentation
D. meiosis
The table shows some characteristics of Bottlenose dolphins that help calves survive and reach reproductive age. How are MOST of these characteristics acquired?
A. through contact with their siblings
B. through eating foods that are high in proteins
C. through genes that are inherited from their parents
D. through interactions with other aquatic species in the ocean
