This represents the example of founder effect.

The founder effect is a term in genetics that describes the loss of genetic variation as a result of new population formation by a very small number of individuals from a larger population. Small group of migrants (the afrikaner population of south Africa) that is not genetically representative of the larger population (Europe population) forms a new population with lower genetic variation.

<u>Answer</u>: Founder effect.

<u>Explanation</u>:

  • The <em>founder effec</em>t is caused when a small group of individuals becomes separated from a larger population and move into a new area. This smaller population, moving to a new area forms the founder population.
  • Since a new population is established from a smaller population it leads to a loss of genetic variation and, this effect is known as founder effect and this is the reason why<em> Familial hypercholesterolemia is more frequent in the afrikaner population </em>

Answer:

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

Think about all of the figures that illustrate tracheids. What are the functions for tracheids? How can you identify a tracheid
kotykmax [81]

Answer: The tracheids have important functions in the plant.

Explanation: The mechanical support is provided by the lignified walls of tracheid cell. the helps in other functions of the plant such as transporting water and getting the solute from the root to the stem and eventually the leaf of the plant.

The tracheids are most useful in the gymnosperms where elements need to be transported.

Identifying a tracheid in a cross section is quire easy as the tracheid cells fit into each other neatly and piled up similarly and have identical shapes as well which makes them obvious from other cells.              

The two examples of tracheid plans could be

  • pteridophytes
  • gymnosperms  

The most common thing that could be found in traceid plant is that this cells are mainly present for transporting either water other solutes in the plant body.

What can create biases in people, sometimes that we are unaware of?
ratelena [41]

Answer:

Views, opinions and ideas

Explanation:

Biases are created through that individual's specific Views, opinions, and ideas. As we grow up we develop unique views, opinions, and ideas based on the experiences we go through over the years that generate a strong feeling towards a specific subject/topic. This subconsciously creates biases that strongly influence future decisions when they even remotely connect with the subject/topic in question.
