Answer:
In water cycle, water evaporates from the sea and oceans in the form of water vapors due to the radiation of the sun. This evaporation in the ocean is the starting point of water cycle.
Explanation:
Water cycle is also called hydrological cycle. In this cycle , water evaporates from water bodies such as rivers, seas, ponds and oceans etc. Water is also evaporated from plant bodies in the process of both evaporation and transpiration. This water moves in the form of vapors and forms clouds. These clouds moves to the land and fall on the earth surface in the form of rainfall and snowfall. From there, this water moves to the oceans through lakes and rivers and repeat the cycle again.
Answer:
Increase occur in skin diseases and decrease occurs in the Earth's average temperature.
Explanation:
If both Carbon Dioxide and Ozone levels began to decrease, increase occur in skin diseases and decrease occurs in the Earth's average temperature. The decrease in ozone levels allows more UV radiation to reach the Earth's surface which lead to various diseases such as skin cancer, cataracts, and weakened immune systems. The atmospheric carbondioxide gas is responsible for the increase of surface temperature by trapping reflected solar radiations so decrease in carbondioxide concentration will leads to lower surface temperature.
Answer:
competition, predation, commensalism, mutualism and parasitism.
Explanation:
FALSE. Wild animals ARE CONSIDERED a natural resource.
Natural resources are resources taken from nature to satisfy our needs. These natural resources are:
1) Air
2) Water
3) Soil
4) Plants
5) Animals
6) Minerals
7) Forests
8) Natural Gas
9) Coal
10) Petroleum
Answer and Explanation:
the total length of the gene is 6,000 base pairs (or) 6.0 kb and it has five exons, four introns and a 1,000 base pair length flanking region for the transcribed region.
Hence, each exon has (1500/5) = 300 by
each intron has (3500/4) = 875 by and
flanking segment (5' and 3') length for the transcribed region would be (1000/2) = 500 bp.
The gene segment is as shown in the <em>1st diagram attached below </em>
In eukaryotes, transcription takes place in the nucleus which results in the synthesis of hnRNA (heteronuclear ribonucleic acid). This hnRNA (pre-RNA) has both introns and exons, however when it is synthesized or while it is being synthesized the Spliceosomal complex removes introns from hnRNA and becomes converted into mRNA (messenger RNA) in the nucleus itself.
(<em>second diagram explains further)</em>
Now the synthesized mRNA reaches the cytoplasm. So, if mRNA collected from the nucleus and cytoplasm will have the same length of about 2,500 base pairs only. Therefore, after the commencement of northern blot analysis both mRNA will yield the same kind of result and have unique length.
