Identify if the properties below belong to LIPIDS, PROTEINS, NUCLEIC ACID, or CARBOHYDRATE Nucleic Acids
1. Composed of nucleotides.
_2. Enzymes facilitate chemical reactions and other functions.
Proteins and Lipids 3. Make up the cell membrane.
_5. Energy storage dissolves in water because its polar.
6. Codes for enzymes and other proteins that are used to catalyze chemical reactions.
_7. Can serve as antibodies for white blood cells.
Carbohydrates
8. Main source of energy for the body.
9. Nonpolar long term energy storage that won't dissolve in water
10. Determine the order of amino acids in a protein sequence.
Lipids
11. Made up of fatty acid chains.
12. Serve as the support structures in plants and fiber for humans.
Lipids
13. Insulate the human body and protects organs.
Protein
14. Monomers are amino acids.
15. Serve as attachment sites to transport chemicals through the body.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

maybe because its impossible for balloons to lift a whole entire house.
