Answer:
Brown eyes = 0.5
Blue eyes = 0.5
Explanation:
Given, B ( brown eyes ) is dominant over b ( blue/light eyes ). So,
BB = Brown
Bb = Brown
bb = blue/light
Mr. O'Ryan = blue eyes = bb
Mrs. O'Ryan = heterozygous brown eyes = Bb
Their children: Bb X bb :
B b
b Bb bb
b Bb bb
Half of the children will have Bb genotype and brown eyes, other half will have bb genotype and blue eyes. Hence, Kellan O'Ryan has 0.5 probability of blue eyes and 0.5 probability of brown eyes.
Answer:
A
Explanation:
There are different mechanisms for transport of molecules across the cell membrane. One kind of this transport is facilitated diffusion, this is a form of passive transport, not requiring any ATP (the opposite would be active transport, where it does require ATP.
Simple diffusion does require special transport proteins, and neither does osmosis. Filtration is a technique used for sterilisation of water, where any impurities can be drawn out of the liquid
If the producer were to disappear then all the other organisms will either go extinct, survival of the fittest, or have to adapt to the change.
Answer:
C. A steep slope
Explanation:
Erosion is the removal of the top layer of the earth or the gathering of lose weathered materials from rock surfaces.
Agents of erosion are wind, water, glacier and gravity.
Along a very steep slope, erosion is highly rife and very prevalent to the extent that everything there is washed away to be deposited at the bottom of the slope or where gradient is more gentle.
On a steep slope, materials moves rapidly and gravity is very great. When these factors are coupled with the prevailing conditions in a place, little to no deposition occurs for soil formation.
