Answer:
Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.
Explanation:
1. The conversion of liquids into gas is termed
as Evaporation.
2. The conversion of Gas into liquids is called
Condensation.
3. The falling of water droplets in the form of
rain after condensation of clouds is called
Precipitation.
4. The cyclic exchange of water into its different
stages is called Water Cycle.
5. The amount of water vapor present in the
atmosphere is called the Humidity.
Answer:
Radiolabeled carbon atom in CO2
Explanation:
Photosynthesis is the process by which green plants fix the atmospheric CO2 into glucose. The process includes carbon fixation during which RuBisCo enzyme catalyzes the reaction of CO2 and a five-carbon compound called RuBP to form 3-phosphoglycerate (3-PGA). The 3-PGA enters the reduction phase of the Calvin cycle wherein it is reduced into glyceraldehyde 3-phosphate. Two molecules of glyceraldehyde 3-phosphate make one molecule of glucose.
To test the hypothesis that glyceraldehyde 3-phosphate from photosynthesis is used by plants to synthesize lipids, radiolabeled CO2 must be used. The radiolabeled carbon atom in the CO2 would be fixed in the form of glyceraldehyde 3-phosphate. If the plant uses glyceraldehyde 3-phosphate as a precursor for lipid synthesis, the synthesized lipid molecules would carry the radiolabeled carbon atom.
Gradualism is a pattern of evolution in which a species evolves at a slow, steady space. The correct answer is C.
Answer:
Chromosome pairs with its corresponding homologous chromosome to form a tetrad.
<span>Alleles are each of two or more alternative forms of a gene that are found at the same position in a chromosome. Traits on the other hand, are the characteristics that are defined by genes. So the combination of alleles for a gene is what manifests itself into a trait.</span>
