Biology
This is a type of cell division where 4 haploid cells are formed.
A: Mitosis B:Meiosis C: Gametes D: Sexual
B - Meiosis
Meiosis is used for sexual reproduction. It has two rounds of cell division making four haploid daughter cells called gametes.
These are the only two planets in our solar system without moons... A: Mercury & Venus, B: Venus & Mars, C: Uranus & Neptune, D: Neptune & Pluto
A: Mercury & Venus.
This is the number of base pairs which is required to form an amino acid.
A: 6 B: 2 C: 3 D: 4
C - 3
This is the result of a medium mass star.
A: White Dwarf + Black Hole.
B: Neutron Star + Black Hole
C: White Dwarf + Black Dwarf
D: Neutron Star + Black Dwarf
C- White Dwarf + Black Dwarf
This is a phase in both mitosis and meiosis. In this phase chromosomes form.
A: Anaphase B: Interphase C:Telophase D:Prophase
D - Prophase.
•DNA begins to form into chromosomes
•The chromosomes are X shaped because the two copies of DNA made during replication are still attached
This is a light year.
A - 30000000 km/s B - 9.5 x 10^12km
C- 950000000km D - 3 x10^7km
This is the part of a cell where DNA is found.
A: Mitochondria B: Nucleus C: Cytoplasm
D: Chloroplast
B: Nucleus
This is the hottest star.
A: Sun B: Red Giant C: Blue Giant D: White Dwarf
C - Blue Giant
This is the number of chromosomes that you will find in diploid cells.
A: 12 B:24 C:23 D:46
D - 46.
23 from your father and 23 from mother.
This is the first stage of the life cycle of a star before a protostar is formed.
A - Main Sequence B - Planetary Nebula C- White Dwarf D- Nebula
D - Nebula
This is the scientist who introduced the theory of natural selection.
A: Darwin B: Lamark C:Haeckel D:Wallace
A: Darwin.
This indicates the brightest star.
A: 10 B: 1 C: - 4 D: -10
D: -10
This was the first genetically engineered organism. A: Corn, B: Tobacco, C: Sheep, D: Rat
B. tobacco plant. In 1983, a tobacco plant, designed to be resistant to certain herbicides, was grown in Wisconsin.
This is the number of planets in our solar system.
A: 5 B: 8 C:10 D:7
B - 8.
This is the correct match up for nitrogen bases pairs.
A: Adenosine + Guanine, Cytosine + Thymine
B: Cytosine + Adenosine, Guanine + Thymine
C: Thymine + Adenosine , Guanine + Cytosine
C - Thymine + Adenosine, Guanine + Cytosine
This is the diameter of our sun.
A: 3474km B: 139820km C: 1.39 million km
D: 987 200 040 km
C: 1.39 million km
This animal has the highest blood pressure... A: Giraffe, B: Blue Whale, C: Elephant, D: Flea
What is A: Giraffe. Because of its extremely long neck, the giraffe must rely on its oversized heart (two feet long and twenty-five pounds!) to pump blood all the way to its head. As a result, the giraffe has the highest blood pressure of any animal: 280/180 mmHg (millimeters of mercury) at heart level when prone -- more than twice the blood pressure of an average human. Not surprisingly, because of their high blood pressure, giraffes are prone to heart attacks.
The planets make up this percentage of the mass in our solar system... A: 0.0135 %, B: 0.135 %, C: 1.35 %, D: 13.5 %
B: 0.135 % of the mass in our solar system. The Sun dominates, accounting for 99.86 % of the entire solar system's mass.
This is the scientist who took the photo that enabled scientists to confirm the double helix shape of DNA.

Red Shift is.
A: Wavelengths compressed, moving towards.
B: Wavelengths stretched, moving towards.
C: Wavelengths compressed, moving away.
D: Wavelengths stretched, moving away.
