How are convection currents produced in the air?

Biology
1 answer:
nika2105 [10]4 years ago
7 0
Convection currents are caused by the colliding of cold and warm air. At night, air above water is warm and air above land is cold. The opposite is true in daytime. When the warm air hits the cold air, which is more dense, it is pushed upward. Then it travels laterally until it cools. It comes back down and pushes up the former cold air, which is now warm. This repeats many times.

The reason that the mail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis
Ilia_Sergeevich [38]

Complete question:

True or False: The reason that the nail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis.

Answer:

False

Explanation:

Nails are composed of the lamina, which is a smooth, shiny, translucent, and keratinized structure. The nails are born the nail matrix. The newly formed nail slice along the mail bed, which is the plane surface under the nails.  

The nail bed places under the nail and is composed of a thin epithelium, with no granulous stratum, and a few layers of parakeratotic cells attached to the nail.  

The nail matrix and nail bed have melanocytes. Half of the melanocytes of the matrix produce melanin, while melanocytes of the nail bed are inactive.  

The nail bed is laying over many small vessels that nourish it and provides a pink color to the nails.

Answer:

Explanation:

An orange is still a plant and the child is drinking it, but it is still consuming it, so I'd say that that's still eating nonetheless.
