Answer:

D. All of the above

Explanation:

Just as when we grow and need more food and energy so does a cell. when a cell is growing there is more of it that can be utilized putting more stress on the DNA to code whatever it needs. The bigger the cell is the denser and thicker the cell membrane gets making it harder for materials to work its way in and out of the cell.

Why does the potential energy and the kinetic energy change when the skateboarder is at the top or the bottom of the hill why do
Brut [27]

Answer:

Potential energy is gaining all the way to the top of the hill due to the increase of height (gravitational pull) on the skateboarder. At the top of the hill potential energy will reach its highest point. Then going down kinetic energy increases as potential energy decreases.

irakobra [83]

Answer:

Incomplete dominance is the inheritance pattern where the dominant allele did not mask the recessive allele completely and form a mix of both alleles. Here the inheritance is the incomplete inheritance. The ratio of F2 generation is 1:2:1.

Given:

R1R1 = 42

R2R2 = 39

R1R2 = 86

Total R1 alleles = 2*42+86 = 170

Total R2 alleles = 2*39+86 = 164

Total alleles = 334

Frequency of allele R1 = 170/334 = 0.51

Frequency of allele R2 = 164 / 334 = 0.49

Expected number of each phenotype:

Total population = 167

Blue = R1R1 = 0.51 * 0.51 * 167 = 43.44

Green = R2R2 = 0.49 * 0.49 * 167 = 40.10

Cyan = 2*R1*R2 = 2*0.51*0.49*167 = 83.46

Phenotype     Observed(O)    Expected (E)    O-E      (O-E)2     (O-E)2/E

Blue                 42                   43.44               -1.44       2.0736     0.0477

cyan                86                   83.46                 2.54     6.4516     0.0773

green              39                    40.1                    -1.1       1.2100      0.0302

Total              167                     167                                               0.1552

Chi-square value = 0.155

Degrees of freedom = no. of phenotypes – 1

Df = 3-1 = 2

Critical value = 5.99

Chi-square value of 0.155 is less than the critical value of 5.99. So we accept the null hypothesis.

ivolga24 [154]

Emergency Operations Centers (EOCs) are the National Incident Management System (NIMS) command and coordination structures that are offsite locations where staff from multiple agencies come together.

Emergency operations center (EOC) is a control facility that functions mainly for incident response. This center serves as a central intelligence arena where response team personnel and decision makers gather and analyze extremely important information, organize response activities, make decisions that guards life and property, communicates with staff and response team personnel and ensure the consistent existence and operation of the organization.

How do we determine a middle<br> atom without looking at<br> electronegativity?
IgorLugansk [536]

Answer:

An atom's electronegativity gets higher as you move up in the periodic table. Thus, the atoms in the top right have the highest electronegativities and the atoms in the bottom left have the lowest ones.
