Answer: This is What drives ocean currents
- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)
- Deep is slower, driven primarily by density (salinity and temperature) differences
- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine
- Halocline: dramatic gradient in saline, increase as it deepens
- Pycnocline: resulting change in density (50-1000)
P= Prokaryotic and E= Eukaryotic
E) Does have a membrane bound nucleus.
P) DNA is free floating in the cell.
P) Bacteria is an example of this type of cell.
P) More organisms made of these cells are unicellular.
P) Does not have a membrane bound nucleus.
E) DNA is found in the nucleus of the cell.
E) All plants and animals are made up of this cell.
E) Most organisms made up of these cells are multicellular.
Answer:
Random mating
Explanation:
Random mating is a type of mating that allows individual to have equal chance of been mated to.
AA genotye is mated with aa from a population and they produce
Four individuals with Aa
AA × aa
!
F1: Aa Aa Aa Aa
This individuals then intermate in the next generation to produce an offspring with three difference genotype AA, Aa, aa in ratio 1:2:1 this is called segregation of genes. This allow to see the variation and hidden features of the individual mated.
Aa × Aa
!
AA Aa Aa aa
F2: 1/4 AA, 1/2 Aa, 1/4 aa
This would be an example of a physical change. The salt is still salt, it just dissolved.
Answer:
B
Explanation:
6.0-7.0 pH is important because most horticultural crops will grow satisfactorily in these levels. It also influences the amount of pH available in the soil, like answer B states.
