Answer:

C. Document the number of honey-making bees per hive.

Explanation:

Among the given options, the only useful criteria towards the experimental design of honey production are to "document the number of honey-making bees per hive". We know that the increased number of animals would increase the workforce and thus increase the production of honey (direct relation). Therefore, this will give a direct assessment of honey production.

Free_Kalibri [48]

Answer:

Fixation

Explanation:

The majority of nitrogen is fixed by bacteria which are symbiotic with plants which are converted to biologically useful forms by specialized bacteria. This occurs in two steps:

  • bacteria convert ammonia in to (nitrites) NO₂,
  • bacteria species convert it to NO₃ (nitrate).

Nitriates are a form of nitrogen that is usable by plants. It is assimilated into plant tissue as protein. The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.

Science when birds remain airborne and moving without flapping their wings, on what are they gliding?
Citrus2011 [14]

Soaring is a science when birds remain airborne and moving without flapping their wings. They are maintaining thrust and gliding downward but staying aloft

<h3 /><h3>Further explanation</h3>

Soaring birds is where the birds can maintain flight without wing flapping, because they using rising air currents. Many gliding birds are able to lock their extended wings by means of a specialized tendon. Some land birds such as vultures and certain hawks, sustain flight for long periods without flapping their wings.

For example soaring California Condor spreads its primary feathers so that each acts as a small, high-aspect-ratio wing. This reduces turbulence at the wingtips and helping the condor to stay aloft circling slowly in thermals.

Vultures have a low aspect ratio (ratio of length to width of the wing) which generally produce a lot of drag. Vultures overcome the problem of by flying with their primary feathers extended, creating slots between them. Each primary serves as an individual high-aspect-ratio wing. This high-aspect-ratio reducing wingtip turbulence and lowering the stalling speed of the wings. This helps vultures to circle in thermals, maintaining thrust by gliding downward, but staying aloft by sinking at a rate slower than the hot air rising.

Svetllana [295]

Answer:

provide flexibility

Explanation:

According to my research on studies conducted by various medical professionals, I can say that based on the information provided within the question the role of elastic fibers is to provide flexibility. Elastic fibers contain elastin, a protein that acts like rubber and allows them to stretch and recoil like rubber bands, making them very flexible.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
