The food web above represents feeding relationships in a biological community near a deep-sea hydrothermal vent. Hydrothermal ve

nts are geysers on the seafloor that gush super-heated, mineral-rich water. The seawater surrounding hydrothermal vents typically contains carbon dioxide (CO2), molecular hydrogen (H2), hydrogen sulfide (H2S), and methane (CH4). Sunlight, however, fails to reach the seafloor where deep-sea hydrothermal vents are located.
As part of an investigation, researchers collected living specimens from an area near a deep-sea hydrothermal vent. Mussels in the collection were found to be dependent on molecular hydrogen in seawater. Also, the researchers discovered multiple species of bacteria living in the gills of the mussels. Mussels use gills for filter-feeding and gas exchange with the surrounding seawater. On the basis of their experimental results, the researchers hypothesized that some bacteria living in the gills of the mussels are capable of chemosynthesis. Which of the following best explains how biological communities near deep-sea hydrothermal vents can exist in a habitat lacking sunlight?

Answer: the bacteria in the habitat are the primary producer that relies on chemosynthesis (ability of organisms to produce their own food by anabolism of chemicals). Due to the the presence of h2S (hydrogen sulphide), the organisms are most probably Sulphur bacteria, liberating hydrogen as by products. This ability means that the bacteria can flourish without sunlight. The mussel are the secondary filter that feeds on the flourishing bacteria population. This build up to form a community whose primary energy source is from the minerals liberated by the vent and hence doesn't require sunlight.

Answer:

I would say B is the answer.

Explanation:

An applied force is a force that is applied to an object by a person or another object. Example: pushing a box to the other side of a room.

A normal force is a force that surfaces exert to prevent solid objects from passing through each other. Example: resting a book upon a table.

Drag is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This doesn't really match the force we use.

However, an attractive force is a force by which one object attracts another. Example: two magnets pulling/colliding together. This is a good example of a force we exert on objects when it is pulled toward us.

in humans, dimples are dominant to no dimples. cross a woman with no dimples with a man who is heterozygous for dimples. determi
OverLord2011 [107]

Genotype: 50% Aa and 50% aa

Phenotype: 50% Dimples and 50% no dimples

Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.

Hope this helps!
