Answer:

Explanation:

A. Inactivation of an enzyme that degrades M-Cyclin.

         M-phase cyclins form M-CDK complexes and drive the cell's entry into mitosis from G2 phase as non-degradation of M-Cyclin resulting from inactivated enzyme can only result in constitutive entry of the cell in to M phase instead cell cycle being arrested at G2 phase,

         

B. Inactivation of the Wee-1 kinase.

         Wee1 is a nuclear kinase that plays a key role in regulating cell cycle progression. Wee1 inhibits the entry of the cell into M phase by inhibiting Cdk1. Wee1 phosphorylates Cdk1 there inhibiting the kinase activity of Cdk1 which is essential for progression from G2 to M phase. As such any mutation of wee1, and the resulting loss of activity will result in premature entry of cells into M phase instead of getting arrested at the G2 phase resulting in smaller yeast cell.

C. Inactivation of the Cdc25 phosphatase

               CDC25 phosphatases removes inhibitory phosphate residues from cyclin dependent kinases resulting in the activation of CDKs which causes the cells in G2 phase to entry to M phase. Mutation in CDC25 phosphates removes the ability of CDC25 to remove phosphate residues from CDKs thus preventing the entry into M-phase.

Therefore, mutant phenotype of cell cycle arrest prior to M phase can only result form mutation in

HELPPP ME PLZZZ IM DUM IKKK
Margarita [4]

Answer:

brown in summer, grey in winter -> camouflage from predators

storing fat during the summer -> gives them extra energy in the winter when there is less food

antlers with forward projections -> allows them to dig in the snow to uncover more food sources, also good for fighting predators

widely spaced hooves -> easily walk on snow and to dig for more food

migrate in herds -> find new area for more food & escape extreme weather, predators, and pesky bugs

Answer: <span>B) Plant trees along canals and roadways on their property to filter runoff and prevent soil erosion

--------

The roots of trees help prevent the soil from being easily eroded by holding the soil in place and taking up the water. The other choices, A, C, and D would cause further erosion by removing objects that would stop the rain or by aiding erosion due to gravity.

Which of the following best explains the greater rate of transport for solute A than for solute B at higher solute concentration
lukranit [14]

The best explanation for the greater rate of transport for solute A than for solute B at higher solute concentrations is that there are more frequent collisions of molecules of A than that of B.

<h3>How does concentration affect transport of molecules</h3>

  • Concentration is the amount of solute dissolved in a given volume of solution.

Given two solutions A and B of different concentrations, The solution of higher concentration will have a higher amount of dissolved solutes.

Given A has a higher concentration, the solutes will collide with themselves much more than in B.

Hence, the molecules of A will tend to move faster than that of B.

Therefore, the best explanation for the greater rate of transport for solute A than for solute B at higher solute concentrations is that there are more frequent collisions of molecules of A than that of B.
