According to the diagram of the water cycle, what happens to the water in the oceans before it becomes water in the atmosphere?

OverLord2011 [107]

Within the water cycle, the water within the ocean evaporates and is converted into a gaseous form before it is able to enter the atmosphere (Answer A). High in the atmosphere, the water then cools and condenses, forming water clouds that eventually rain back to the ground and ocean.

Economic benefits of forest

omeli [17]

Forests play an important role in the economic development of a country. They provide several goods which serve as raw materials for many industries. Wood grown in forests serves as a source of energy for rural households.

Most of the world’s paper is made from wood and one rather reliable index to the degree of economic development of a country is its per capita consumption of paper. As an economy develops economically, paper is used as packaging material, in communications and in scores of other uses. No really satisfactory substitute for paper exists for many of its uses.

While it has long been recognized that forests play many roles in the economic development of a country in addition to providing wood fiber for many uses, the non-wood outputs of forests are coming increasingly to be recognized and valued everywhere in the world. Forests have watershed values especially in areas with fragile and easily eroded soils; tree cover may be highly valuable simply as protection to the watershed.

Forests are valued as a place for outdoor recreation. The kinds of forests most valuable for outdoor recreation are not always the same as the kinds most valuable for wood production and vice versa. The dense forest with trees closely spaced to take full advantage of the sunlight, moisture and fertility to grow wood, is often less attractive to the recreationist than a more open forest.

Forests are the home for many species of wildlife including mammals, reptiles and birds. Some of these forms of wildlife are clearly valuable to man. Ecologists have been much disturbed at the reduction in wildlife numbers, sometimes to the point of extinction, as tropical forests are cleared.

If a particular gene is located on the Z chromosome of this lizard species, describe why a lizard with a ZW genotype has a great

Alenkasestr [34]

Answer:

ZZ species will take more number of crosses to produce a recessive offspring.

Explanation:

Here Z seems to be the dominant allele. A species having ZZ or homozygous dominant genotype shall not express the recessive phenotype until unless it has both recessive allele and this is not possible as of now or is dependent on the genotype of mating species and the number of generations of development.

If ZZ mates with WW, the offspring in F1 generation will have genotype ZW

However, if the offspring in the F1 generation are crossed then in next generation we could see organism with recessive phenotype i,e WW

ZW*ZW

ZZ, ZW, ZW, WW

While in case of organism having ZW type genotype, recessive phenotype will occur in the first generation cross with the ZW.

How could the cell membrane then be important for homeostasis

Masteriza [31]

Answer:

The cell membrane is an important factor for homeostasis to happen.

Explanation:

Because the cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
