By Pleistocene hangovers, Buchanan means: Biological traits that we have today that are the result of selective pressures that e

xisted thousands of years ago but no longer today. Biological traits that we have today but would not have had in the environment that existed thousands of years ago. Biological traits that are better in terms of quality of life to have today, even though the selective pressures that allowed for those traits do not exist today. Selective pressures toward perfection that feel like a hangover because perfection is impossible. Selective pressures that exist today that tend to push human beings away from the pursuit of perfection.

Achondroplasia is a common form of dwarfism caused by an autosomal dominant mutation in the fibroblast growth factor receptor 3
ollegr [7]
<h2>Symptoms of Achondroplasia</h2>

Explanation:

  • Achondroplasia is caused about by a quality change (transformation) in the <em>FGFR3 gene</em>
  • The <em>FGFR3 quality</em> makes a protein called fibroblast development factor <em>receptor 3 </em>that is engaged with changing over ligament to bone
  • <em>FGFR3</em> is the main quality known to be related with <em>achondroplasia Achondroplasia</em> is acquired in an autosomal predominant example, which implies one duplicate of the adjusted quality in every cell is adequate to<em> cause the confusion</em>
  • In the rest of the cases, individuals with <em>achondroplasia </em>have acquired an adjusted <em>FGFR3 quality</em> from a couple of <em>affected parents</em>

Identify one way in which the process of growth of a human embryo is similar to the process of reproduction in a single called o
iragen [17]

Answer:

The correct answer would be mitosis and binary fission.

The human embryo grows through the process of mitotic divisions through a parent cell divides into two equal sized daughter cells each of which contains identical genetic material.

Similarly, single-celled organisms reproduce asexually through the process of binary fission during a parent cell divides into two equal sized daughter cells each of which contains identical genetic material. Each daughter cell grows and matures to become an independent adult.

Compare the stucture of a food web with a food chain
zvonat [6]

 food chain:The simplest representation of energy in a community. At the base is energy stored in plants, which are eaten by small organisms, which in turn are eaten by progressively larger organisms; the food chain is an oversimplification in that most animals do not eat only one type of organism.  

------------------  

food web:the interconnected feeding relationships in an ecosystem. These relationships can be complex; some organisms may feed on more than one trophic level, or changes may occur depending on a species' life history stages or the availability of food.
