It’s either A or B. I would probably say A because, In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules and nutrients into organic matter using the oxidation of inorganic compounds or ferrous ions as a source of energy, rather than sunlight, as in photosynthesis. Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse. Groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria. Many microorganisms in dark regions of the oceans use chemosynthesis to produce biomass from single carbon molecules. Two categories can be distinguished. In the rare sites where hydrogen molecules are available, the energy available from the reaction between CO₂ and H₂ can be large enough to drive the production of biomass.
Answer:
B. Birds allow their temperature drop in order to increase their production efficiency.
Explanation:
Most birds can drop the temperature a few centigrade degrees, while there are torpid birds capable of lowering much more. Birds can drop body temperature in response to environmental conditions. Bird species including, among others, swifts, hummingbirds and chickadees are capable of regulating body temperature during torpor state. There are different morphological and behavioral adaptative traits that enable birds to minimize the cost of thermoregulation. In the first place, epidermis surface allows heat loss to the environment, while arteries and veins in the legs help to retain heat in cold conditions.
Answer:
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air.
Explanation:
Answer:
Potential energy is energy that has not been used
The Vikings were able to effectively use their longboats because of the
following:
- The boats moved swiftly and efficiently in the water making it easy to evade their enemies.
- The longboat rode high in the water, allowing it to sail further in the shallow water and transport the vikings closer to shore.
- The long boat was not only fast, but also light enough to be carried over land fortifying bridges.
Vikings made use of the long boat because it was light weighted and the
people could carry it.
The light weight of the ship also ensured that it moved swiftly and was able
to sail in shallow waters.
