<span>In biological terms, the structure of a species is usually best adapted to give it the most advantageous functional ability, though this is not always the case. When a structure has a function that allows the species to survive and promulgate its genetic structure, the individual will be more likely to reproduce its genotype over those that are not structurally advantageous.</span>
<u>Answer</u>: 2
The convection currents shown in points 1 and 3 transfer heat from the outer core (number 4) to the lithosphere. Here, the lower density hot magma breaks apart the plates at <em>point 2</em> creating a divergent plate boundary. <u>This new magma mass will drive a lateral movement of the plates</u>. The edges of the plates which have a higher density basalt rock will sink into the mantle and get consumed in trenches/subduction zones
The correct answer is C. all organisms in the domain have eukaryotic cells.
The Eukarya differ from Archaea and Bacteria in that their cells are eukaryotc, meaning they contain a membrane enclosed nucleus and other membrane enclosed organelles. Archaea and bacteria have prokaryotic cells, meaning their cells do not contain a membrane enclosed nucleus or other membrane enclosed organelles.
Select all the correct answers. Which two statements are true about energy transformations?
Energy is never released from an object as heat.
Energy is never transformed between kinetic energy and potential energy.
<u>Energy is never created. </u>
Energy is never completely transformed.
<u>Energy is never destroyed.</u>
Answer:
Mainly because if a disorder is dominant, then it will be manifested by all who have the gene. If the disorder is severe, then it will reduce the chances of the individual surviving to grow up and reproduce (unless the disorder only manifests symptoms in later life). If they do reproduce, then 50% of their offspring will inherit the gene, and be at a similar disadvantage in reproduction. Thus, there is likely to be selection against the gene. By contrast, a recessive disorder is only manifested if both parents pass on the abnormal gene, and an individual with one gene for the disorder is usually at no disadvantage. Thus, there is much less selection against abnormal recessive disorders.
