The Earth is made up of many different types of _ _ _ _. A landscape can be made up of more than one rock type.
Physical weathering is caused by changes in _ _ _ _ _ _ _ _ _ _ _ or _ _ _ _ _ _ _ _. There are 2 main types of physical weathering: _ _ _ _ _ _- _ _ _ _ (takes place when water is trapped in the cracks of rocks and freezes. The frozen water expands and enlarges the cracks in the rocks) and _ _ _ _ _- _ _ _ _ (takes place in hot desert climates. Changes in temperature cause the surfaces of the rocks to expand and contract which causes thin layers of rock to peel off!).
Chemical Weathering occurs when _ _ _ _ _ _ _ _ attack and break down rock surfaces. _ _ _ _ _ _ _ _ _ is weathered in this way.
Biological weathering involves _ _ _ _ _ _ and _ _ _ _ _ _ _ . Plant seeds can begin to grow in the cracks of the rocks. As the roots _ _ _ _ _ _ the cracks in the rock expand, the rock _ _ _ _ _ _ _ and pieces break off!
Once rocks have been broken down they may be _ _ _ _ _ _ and/or

During meiosis, homologous chromosomes line up next to each other. In some
cases, one arm of a chromatid crosses over the arm of another chromatid. What is
the result of this process?
the independent assortment of genetic material
the creation of an additional sex cell
continuity in the offspring cell's DNA
additional variation in the DNA of each sex cell formed
Crossing over is a mechanisms involved in introducing genetic variation. When the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed. Option D.
---------------------------------------
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
So, according to this information, when the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed.

How will distinguish between natural and artificial fibres by observing the smell produced when burnt?
its not biology it's chemistry
Answer:
Natural fiber smell like paper whereas artificial fiber smells like an acid.
Explanation:
We can distinguish between natural and artificial fibers by observing the smell produced when burnt because both produces different types of smell when burnt. When the artificial fibers are burn, it produces acid or chemical like odor and leaving a plastic like bead while on the other hand, when the natural fiber burn, it produces smell of burning paper or hair and leaving ash of soft and grey colour. Natural organic fibers burn rapidly with a yellow flame.

Describe how people change their body shapes (not their clothes) when they are very hot and when they are very cold. Use your knowledge of surface area : volume ratios to explain why we do this.
Answer:
This quesiton is unclear
Explanation:
The body has negtive feedback loops that either vasoconstrict (preserving heat by lessening the surface area of blood vessels so they are exposed to less cold and release less heat) and vasodilation, where blood vessels are expanded and have higher surface areas so the body hopes to lose more heat to cool down.
If this is purely body language (like going into a fetal position when its cold: to lessen the surface area exposed to the cold temperature and lose less heat, imagine an ice cube vs. a long thin tube of ice with equal volume, the cube will last longer. Similarly our bodies would spread out to release more heat (unless there was sun) this is to expose the most surface area, allowing our body to release the most heat. Note: this is pretty insignificant change, and in extreme temperatures will likely not help, but it does contribute.

An underground water supply has a depth of 200 m of water. Water seeps in at the rate of 4 cm / year . Water is pumped out at the rate of 1m / year . How long will this water supply last? To find the net water loss from an underground water supply, subtract the amount that seeps into the water sup ply from the amount removed from the water supply. How long will the water supply last if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year ?
Answer:
208 years.
Explanation:
The water supply last for 208 years if the water seeps in at the rate of 4 cm / year and water is pumped out at the rate of 1m / year. The water supply last forever if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year because the same amount of water enters the underground which can be pumped from the soil. If more water is extracted from the soil as compared to it seeps, so with the passage of time water concentration in the soil decreases and in the last it disappeared.
