The Amish population who migrated from Europe to the United States had very few individuals in their population. Additionally, their gene pool shows very few alleles due to inbreeding. A genetic trait called polydactyly (having six fingers), which is rare in other populations, is common amongst them. What kind of evolutionary effect is exhibited in this example?A. Mutation
B. Natural selection
C. Founder effect

Answers

Answer 1
Answer: The Amish have a genetic trait called polydactyly which is rare among other populations of people. This means that a person can 6 fingers, usually an extra thumb. This kind of evolutionary effect that is exhibited in this specific example is called the Founder effect. This happens when there is a small number of colonizing ancestors. 
Answer 2
Answer: founder effect since it refers to migrating population

Photosynthesis uses sunlight to convert water and carbon dioxide into

Answers

Photosynthesis uses sunlight to convert water and carbon dioxide into high-energy sugar (glucose) and oxygen. 


 

Final answer:

Photosynthesis uses sunlight to convert water and carbon dioxide into glucose and oxygen. This process occurs in the chlorophyllum cells within plants and plays a huge role in the carbon cycle and release of oxygen into the atmosphere.

Explanation:

The process of photosynthesis uses the energy from sunlight to convert water (H2O) and carbon dioxide (CO2) into glucose (C6H12O6) and oxygen (O2). This reaction occurs primarily in the chlorophyllum cells within plants. Photosynthesis is a vital process for life on Earth, as it is the primary source of food for plants. Moreover, it plays a significant role in the carbon cycle, and ultimately, contributes to the release of oxygen in the atmosphere which is necessary for the survival of most organisms on the planet.

What results when the combined effect of two different drugs taken together exceeds the sum of the individual drugs administered alone?

Answers

Options:

A) Hyperadditive

B) Antagonistic

C) Cross-tolerance

D) Cross-dependence

Answer:

A) Hyperadditive

Explanation:

Hyperadditive is what results when two drugs  are added together to produce an amplified effect greater than the effect of the sum the individual drugs administered independently. The effect of this drug interaction is triple. I.e. 1 + 1= 6 Synergistic drug interaction results in hyperadditive. Examples of such drug interaction that results in hyperadditive are heart medication plus licorice, ulcer medication plus Coumadin, ibuprofen plus Coumadin.

What is the second phase of mitosis

Answers

Answer:

Metaphase

Explanation:

During metaphase, parts of the spindle extend and the chromosomes align at the middle part of the cell. Notice that each chromosome consists of two identical strands held together at a point in the middle.

-Therefore, metaphase is the second stage of mitosis
Metaphase

The second stage of mitosis. In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere.

As a result of the absence of plants in the meadow, the rabbit population will probably

Answers

are there any multiple choices?
anyways, without the multiple choices, the answer will probably be; decrease.
Explanation: a meadow is a field or pasture; a piece of land covered or                            cultivated with grass, usually near a river.
                     Rabbits need lots of water and vegetables, so a meadow is                        usually the best habitat for them. 
                     When the meadow is ruined (plants decrease), their habitat                        is ruined, causing them (the rabbits) to slowly decrease.
                     They could decrease as a result of their death, as a result of                       their migration to a different and more suitable place, or as a                      result of both. Usually, though, it is both, since when animals                      start to die, their species start to move away from that                                  location.

The gram-positive bacteria have a cell wall than the gram-negative bacteria.

Answers

Gram-positive bacteria are easier to destroy because they have a single membrane and cell wall, whereas gram-negative bacteria have a cell membrane, a cell wall and an outer membrane, hence making the bacteria pretty much impenetrable. 

Answer:

Thicker.

Explanation:

Although there are more cell membranes, walls,etc, the CELL WALL of Gram-positiive bacteria itself is thicker than Gram negative bacteria.
