Neptune has five rings: Galle, Le Verrier, Lassell, Arago, and Adams.

The rings are composed of at least 20% dust with some of the rings containing as much as 70% dust; the rest of the material comprising the rings is small rocks.

The rings of Neptune are very dark and probably made of organic compounds that have been baked in the radiation of space.

La pelvis reducida de los cetáceos no tiene actualmente ninguna función.

Explanation:

La pata de un pato es una extremidad que por su estructura le permita nadar perfectamente. En cuanto a la aleta de los peces y ballenas, es una parte de estos animales formada por tejido conjuntivo. Pueden tener distintos tamaños y su principal función no sólo es permitir el movimiento sino también la estabilidad. En cuanto a la pelvis reducida de los cetáceos era algo que tenía sentido en especies de antaño. Durante la evolución, su utilidad de fue perdiendo, como podría mencionarse el ejemplo en los humanos de las muelas de juicio.

Ghella [55]

One reasonable plan would be to wear a face mask or surgical mask. Take note that your surgical mask contains two sides – the white side and the blue side. Since the main purpose of your mask usage is to prevent yourself from inhaling too much bad air, the blue side of the mask should be the one touching your skin. This is because the white side of your mask helps you prevent from coming in contact with toxins that may come from the smog.

ch4aika [34]

Answer choices:

  • A frame shift mutation in the X chromosome of a cheek cell
  • A chromosomal mutation in the Y chromosome of a kidney cell
  • A point mutation in the first chromosome of a sperm cell
  • A substitution mutation in the third chromosome of a uterus cell

Answers:

A point mutation in the first chromosome of a sperm cell

Explanation:

Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.

Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
