Maria wondered if different colors of plastic wrap affected the time for bread to mold. She wrapped aslice of bread in clear plastic wrap. Before wrapping the bread she placed 5ml of water in the center of

the bread. She repeated the process with a slice of bread using red plastic wrap & a slice of bread using

blue plastic wrap. The bread came from the center of the same loaf. In each case she used the same

amount of water and the same brand of plastic wrap. She wrapped the different slices of bread in the

same way.

Independent variable:

I

Dependent variable:

Control:

Answer:

This question is asking to identify the independent variable in the scientific question.

The independent variable is TEMPERATURE

Explanation:

Independent variable in an experiment refers to the variable that is subject to change or manipulation by the experimenter in order to bring about an effect or response in the dependent variable.

In this scientific question that states: What effect does high temperature have on radish germination?, the independent variable is the TEMPERATURE because it is what is being changed in the experiment in order to effect a response in the germination of radish (dependent variable).

Answer:

a. p=0.725, q = 0.275: P=0.51, H=0.43, Q=0.06

Explanation:

Let state our given parameters from the question:

Frequencies of coat color genes at the C locus for population 1 are .85 for C

This implies that the Allelic frequency C for population p1 =0.85

Frequencies of coat color genes at the c locus for population 1 are .15 for c

This implies that the Allelic frequency c for population q1 = 0.15

Frequencies for Care .6 i.e p2= 0.6

Frequencies for care .4 i.e, let that be q2= 0.4

The table below shows a diagrammatic representation of the above expression:

Alllelic Frequency                      C                                          c

Population 1                        (p1)   0.85                              (q1)   0.15

Population 2                       (p2)   0.6                               (q2)   0.4

Now, from above: let think of the table as a punnet square and then cross it together;

                                            (p1)  = 0.85                              (q1) =  0.15

p2 = 0.6                               p1p2                                       p2q1

                                            = 0.6 × 0.85                           = 0.15 × 0.6

                                            = 0.51 (P)                                = 0.09 (H)              

q2 = 0.4                               p1q2                                       q1p2

                                            = 0.85 × 0.4                           = 0.4 × 0.15

                                            =0.34 (H)                                = 0.06 (Q)

From the above table, the heterozygous are represented by (H)

∴ Frequency of heterozygous can be calculated as:

= 0.09 + 0.34

= 0.43

Thus, we can conclude that the progenyF1 genotypic frequencies are:

P= 0.51

H= 0.43

Q= 0.06

Now, let us calculate the allelic frequencies, p and q in F1

p = P + 1/2 × (H)

= 0.51 + (1/2 × 0.43)

= 0.51 + 0.215

= 0.725

q =Q + 1/2× (H)

= 0.06 + (1/2 × 0.43)

= 0.06 × 0.215

= 0.275

Hence, p=0.725, q = 0.275: P=0.51, H=0.43, Q=0.06 , This makes option a the correct answer.

Answer:

Water that falls to Earth from the atmosphere.

Explanation:

Precipitation is any form of liquid or solid water particles that fall from the atmosphere and reach the surface of the earth.

Answer:

Precipitation is water that goes through a process that prosses is water evaporates and the turns into clouds then when there is enough water in the clouds it rains and starts over again.

Explanation:

Answer:

RNA was the genetic material

Explanation:

If avary, Macleod, and McCarty would have seen that only RNAse treatment of the heat-killed bacteria prevented the transformation of genetic virulence than might have concluded that RNA is the genetic material as transformation does not occur because the RNAase degraded the RNA.

But if the genetic material is DNA then RNAase will not work because RNAase can not degrade DNA and then DNA will pass from virulent heat killed strain to nonvirulent strain and will cause transformation.

Answer:

The functions of the skeletal muscles are affected by the CNS via the two sets of neurons, that is, lower motor neuron and upper motor neurons. The PNS comprises sensory neurons and motor neurons. The lower motor neuron is monitored by the upper motor neuron.  

Hyporeflexia occurs because of the dysfunction of the lower motor neuron or its lesion. The lower motor neurons refer to the neurons, which innervate the skeletal muscles directly. Destruction to the central nervous system leads to hyper reflexes and destruction to the peripheral nervous system results in hyporeflexia.
