Answer:

evaporation, condensation, and precipitation.  Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. condensation water which collects as droplets on a cold surface when humid air is in contact with it. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain. properties of ocean water.Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.On the landscape, freshwater is stored in rivers, lakes, reservoirs, and creeks and streams. Most of the water people use everyday comes from these sources of water on the land surface. Lakes are valuable natural resources, both for human and non-human life.

In fruit flies, an autosomal mutation in the gene for wing veining results in cross veinless wings. This mutation is recessive.
mezya [45]

Answer:

B. cv+cv w+w

Explanation:

Fruit flies have a special nomenclature to write the genotype of individuals.

  • If the mutation is recessive, you have to write it with lowercase letter(s).
  • If the mutation is dominant, you have to write it with capital letter(s).
  • Wild-type alleles are indicated with a superscript plus (+).

In this problem, both crossveinless (cv) and white (w) mutations are recessive.

<u>For that reason, a heterozygous individual's genotype for both genes will be written as:</u>

<h2>cv⁺ cv  w⁺ w</h2>
