X= Petal
Y= Male Reproductive Unit (Stamen)
Z= Female Reproductive Unit (Pistil)
X: Pollen Production
Y: Pollen Transfer
Z: Production of eggs
X: Attraction of Pollinators
Y: Production of male sex cells
Z: Egg production and embryo development
X: Protection for embryo
Y: Supply nourishment to embryo
Z: Place of embryonic development
X: Photosynthesis
Y: Production of cells that protect internal organs
Z: Production of egg and sperm.
When red carnations are crossed with white carnations, the resulting flowers are pink. Pink carnations are an example of what type of inheritance pattern?
incomplete dominance
recessive alleles
dominant alleles
codominance
Doctors and scientists group embryonic development into trimesters. Each list below shows development during one trimester, though the lists are not in chronological order.
1. fingernails, taste buds, swallowing, sleep cycle, toenails
2. eyelids, heart beats, makes fist, movement
3. eyes open and close, fastest weight gain
In which trimester do each of the lists correspond?
First Trimester—1; Second Trimester—3; Third Trimester—2
First Trimester—2; Second Trimester—1; Third Trimester—3
First Trimester—3; Second Trimester—2; Third Trimester—1
First Trimester—2; Second Trimester—3; Third Trimester—1
The
reproductive system is a collection of specialized organs, glands, and hormones
that help to produce a new human being. Which male reproductive structure holds
the sperm as it matures?
prostate gland
seminal vesicle
vas deferens
epididymis
Mitosis and meiosis are both processes involved in reproduction. Which statement correctly compares mitosis and meiosis?
Mitosis results in the production of two genetically unique diploid cells and meiosis produces four
genetically identical haploid cells.
Mitosis and meiosis both produce genetic variation within their daughter cells.
Mitosis and meiosis are both divided into only four distinct phases: prophase, metaphase,
anaphase, and interphase.
Mitosis results in the production of two genetically identical diploid cells and meiosis produces four
genetically unique haploid cells.
How are sexual reproduction and asexual reproduction different from each other?
sexual reproduction requires two parents and asexual reproduction requires only one parent
asexual reproduction requires two parents and sexual reproduction requires only one parent
mutation rates are lower in sexual reproduction than in asexual reproduction
asexual reproduction occurs only in multicellular organisms
Which type of reproduction leads to increased genetic variation on a population?
Parthenogenesis
asexual reproduction
Sexual reproduction
Vegetative reproduction
Which of the following phrases best describes cancer?
absence of cyclins in the DNA
multiple gene mutations on a chromosome of DNA
presence of genetic defects caused by hereditary disorders
uncontrolled cell growth caused by mutations in genes that control the cell cycle
The diagram shows a cellular process that occurs in organisms. What is the name of this process?
Mitosis
Meiosis
Endocytosis
Interphase
If the xylem in a young tree is damaged, which process is first affected?
performing photosynthesis
transporting sugar to the roots
transporting water to the leaves
absorbing water from the soil
Which statement describes the role of flowers in plant survival?
Flowers can absorb carbon dioxide for sugar production.
Flowers contain cells that produce gametes.
Flowers produce oxygen through cellular respiration.
Flowers contain cells that carry out photosynthesis.
The diagram shows a cross section of a plant leaf.
How does the structure marked X contribute to the survival of the plant?
It allows the intake of gases necessary for photosynthesis.
It allows the intake of minerals necessary for plant growth.
It allows the intake of sunlight necessary for ATP production.
It allows the intake of sugars necessary for plant reproduction.
In which of the following structures of the female human reproductive system is soon to be fetus implanted and then developed?
uterus
ovary
teste
fallopian tube
Which of the following describes fertilization?
cell differentiation to form a blastula
formation of germ layers in a deuterostome
sperm and egg production
a sperm joining an egg to form a zygote
Below is a diagram of the male reproductive system.
Which structure is represented by the letter A?
Teste
Urethra
Ovary
Seminal Vesicle
Hitchhiker's thumb (H) is dominant to no hitchhiker's thumb (h). A woman who does not have hitchhiker's thumb marries a man who is heterozygous for hitchhiker's thumb. What is the probable genotypic ratio of their children?
75% Hh: 25% hh
0% Hh: 100% hh
100% Hh: 0% hh
50% Hh: 50% hh
Which type of cell division is shown in the diagram?
meiosis because it results in haploid cells
meiosis because it involves one parent cell
mitosis because the daughter cells are identical
mitosis because the daughter cells are not identical
Which of the follow identifies the type of tissue organ X is made of and a physiological process it is involved in?
Meristematic tissue, which protects the plant and aids in transpiration.
Dermal tissue, which protects the plant and aids in growth and reproduction
Dermal tissue, which continuously form a number of new cells and aids in transpiration
Meristematic tissue, which continuously form a number of new cells and aids in growth
