What is true about mutations?
Ninja Turtles
Beneficial to survive
Separates humans from martians
What does mutation do and how does it benefit us?
A change in a gene (DNA), results in a mutation. There are beneficial mutations that help an organism (think about a white fur gene for a rabbit living in the arctic). There are also mutations that harm and can kill an organism (think about diseases like Sickle Cell Anemia). Remember, for evolution to work you need mutations. The white fur mutation for the rabbit helps it to survive in the snow of the Arctic because it is camouflaged.
Gives humans the option to become ninja turtles.

Northern hemisphere and winter (Position of Polaris in the northern hemisphere during the winter solstice...
Because of Druids
The days that one of the Earth’s poles is most tilted away from the sun are called SOLSTICES. On solstices, the sun reaches its greatest distance north or south of the equator, so the sun is at its highest or lowest in the sky at noon. The solstices are around June 21st and December 21st, and they mark the longest and shortest days of the year. The sun is highest in the sky on the summer solstice, and the sun is lowest in the sky on the winter solstice. The longest day of the year is on the summer solstice, and the longest night of the year is on the winter solstice.
What is the best example of Physical Weathering?
Limestone and water
Frost in granite or rock
(Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth’s atmosphere, water, by the movement of rocks, wind, and biological organisms. Swiftly move temps on rocks (freezing), highing water can lift rocks from stream bottoms, ice wedging can cause rocks to break, plant roots can grow through cracks, waves crashing on a rocky shoreline, changing heat temps)

What is in a nucleus?
The NUCLEUS is the control center of the cell. It houses the cell's CHROMOSOMES, which are strands of DNA (DEOXYRIBONUCLEIC ACID), which is the code for genetic information.
The nucleus also includes: NUCLEAR MEMBRANE; a protective double membrane surrounding the nucleus that controls the flow of materials in and out of the nucleus NUCLEOLUS: a small structure found inside the nucleus that makes ribosomes and transports them to the cytoplasm

What has the most ocean life?
The undertow
Sunlit Zone: This is the top layer, nearest the surface.
It is also called the euphotic zone. Here there is enough light penetrating the water on to support photosynthesis. Because photosynthesis occurs here, more than 90% of all marine life lives in the sunlit zone. The sunlit zones goes down about 600 feet.
Anemone
The North Star, is it the brightest star? Does it stay in the same spot every day?
Only on Dec. 25
It is not brightest, stays in the same spot. POLARIS, also known as the North Star, is located directly above the North Pole. In the northern hemisphere, the constellations appear to slowly rotate around Polaris. Different constellations come into view at different times of the night and at different parts of the year. North Star, the Earth is pointed directly at it, stars circle around it, it does not move, northern direction, Earth rotates

keywords algae and birds in it. In actual terms, the surface is different from the bottom because the surface of the water has the most biological production happening because of the sunlight. Once you get down about 600ft the sunlight no longer reaches that far down therefore habitats, food chains, and ecosystems begin to change
