In an experiment to determine whether M phase cells contain a regulatory molecule that initiates mitosis, cytoplasm from M phase

cells and interphase cells was injected separately into interphase cells. Why did researchers inject cytoplasm from interphase cells

Answer:

As a negative guide, to demonstrate that perhaps the injection itself has no impact on the cell cycle.

A successful experiment has handled the same control group as the experimental group with the exception of the variable being examined, in this case the cytoplasm M-phase.

A human RBC is approximately 6 µm in diameter. An unknown bacterium measures 1 ocular space using the oil immersion objective co
butalik [34]

Answer:

The following is the formula to determine the size from minor spaces and ocular spaces on the stage micrometer:  

Size = Number of minor spaces * 10 micrometer / Number of ocular spaces

A = Number of minor spaces is 2 and the number of ocular space is 1,

Size = 2 * 10 / 1 = 20 micro micrometer. Thus, the size of a bacterium is 20 micrometers.  

B = Thus, it can be said that the size of the bacterium is almost 4 times bigger in comparison to a human red blood cell, which is 6 micrometers in diameter.

In hummingbirds feather color is incompletely dominant. A rather large population of hummingbirds has 396 red-sided individuals
GrogVix [38]

Answer:

a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557  x 2) = 1049 / 2420 = 0.433

b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557  x 2) = 1371 / 2420 = 0.567

c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557  x 2) = 649 / 2020 = 0.321

d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557  x 2) = 1371 / 2020 = 0.679

e) migration is gene flow  

Explanation:

Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).
