"__________" is a homemade alcohol produced during the prohibition.
Illusion [34]

By late 1920s most alcohol was made at home.  Alcohol was made at home is the illegal 'stills' because deaths from purposely poisoning alcohol went up from 98 in 1920 to 760 in 1926.  The homemade alcohol was known as moonshine.

Consider the following three populations of birds. Assume HW equilibrium. With these birds red coloring is recessive, while brow
bixtya [17]

Answer:

Red allele frequency will be highest in population II

Population III can undergo bottleneck effect

The frequency of the brown allele will  least likely be altered in the population I

Explanation:

Population I -

Total population - 670

Brown birds - 603

Red birds - 67

Population II

Total population - 100

Brown birds - 90

Red birds - 10

Population III

Total population - 30

Brown birds - 27

Red birds - 3

Frequency of red birds in population I

\frac{67}{670} = 0.1

Frequency of red birds in population II

\frac{10}{90} = 0.11

Frequency of red birds in population III

\frac{3}{30} = 0.1

Red allele frequency will be highest in population II and it will be equal to \sqrt{0.11} = 0.33 as compared to 0.31 in case of population I and III

Population III can undergo bottleneck effect because of smaller population size

The frequency of the brown allele will  least likely be altered in the population that has highest  brown individual , i.e population I

Why are chloroplasts more on one side of a cell than the other
vaieri [72.5K]

You would be referring to the <em>plant </em>cell.

Answer:

Chloroplasts may be seen on all six sides of a plant cell, which is a three-dimensional entity with typically moderately rounded corners (not in the centre because a big central vacuole fills a very large part of the volume). Chloroplasts are constantly being rearranged by the cell since they are not set in place. Chloroplasts are typically located close to so-called periclinal cell walls, which are oriented in the same 2D orientation as the leaf surface under low light. Chloroplasts seem to "escape" to the anticlinal walls in bright light. Better light harvesting in low light by exposing every chloroplast to light and photoprotection by mutual shading in strong light are likely the fitness benefits provided by this behavior. In the dark, chloroplasts also gravitate toward the anticlinal walls. Thin leaves of submerged aquatic plants like Elodea can be used as microscope specimens to observe chloroplast motions. One can gauge how much light gets through a leaf in land plants. What I just said concerning the top layer(s) of leaves' "palisade parenchyma cells" is accurate. Most of the chloroplasts are found in these cells. Numerous cells in the spongy parenchyma under the palisade layer lack well marked peri and anticlinal walls.

<h2>How did plant cells incorporate chloroplasts in their DNA?</h2>

Chloroplasts must reproduce in a manner akin to that of some bacterial species, in which the chloroplast DNA is duplicated first, followed by binary fission of the organelle (a kind of protein band that constricts so that two daughter organelles bud off). As a result of some chloroplast DNA actually being integrated into the plant genome (a process known as endosymbiotic gene transfer), it is now controlled in the nucleus of the plant cell itself.
