According to kagmi on yahoo these are three lines of evidence that support the theory of evolution.
The fossil record shows the existence of billions of extinct species. It also shows a clear progression from one species to the next; there are many "transitional fossils," such as the archeoptryx (probably spelled that wrong, lol) which is clearly an intermediate in the evolution of dinosaurs into birds.
<span>Biogeography shows the distribution of species, providing further support that different species can and do evolve from common ancestors. Australia has many species of marsupials not found on other continents, for example; this implies that these species may have shared a common ancestor which lived on Australia when it was separated from the other continents by continental drift. </span>
<span>Molecular biology allows us to analyze genes and proteins down to the very molecules that make them up. This reveals many similarities and differences between organisms not readily apparent to the naked eye. We can see, for example, that humans share the vast majority of their DNA with all mammals; slightly less with reptiles; slightly less with amphibians, and so on. We find that species' DNA sequences match up well with the fossil record in terms of how closely related the species are. </span>

Explanation:
Mature human milk contains 3%--5% fat, 0.8%--0.9% protein, 6.9%--7.2% carbohydrate calculated as lactose, and 0.2% mineral constituents expressed as ash. Its energy content is 60--75 kcal/100 ml. Protein content is markedly higher and carbohydrate content lower in colostrum than in mature milk. Fat content does not vary consistently during lactation but exhibits large diurnal variations and increases during the course of each nursing. Race, age, parity, or diet do not greatly affect milk composition and there is no consistent compositional difference between milks from the two breasts unless one is infected. The principal proteins of human milk are a casein homologous to bovine beta-casein, alpha-lactalbumin, lactoferrin, immunoglobulin IgA, lysozyme, and serum albumin. Many enzymes and several "minor" proteins also occur. The essential amino acid pattern of human milk closely resembles that found to be optimal for human infants. Possible special functions of milk proteins and enzymes other than as a source of amino acids, are as yet largely speculative. The principal sugar of human milk is lactose but 30 or more oligosaccharides, all containing terminal Gal-(beta 1,4)-Glc and ranging from 3--14 saccharide units per molecule are also present. These may amount in the aggregate to as much as 1 g/100 ml in mature milk and 2.5 g/100 ml in colostrum. Some of them may function to control intestinal flora because of their ability to promote growth of certain strains of lactobacilli. Human milk fat is characterized by high contents of palmitic and oleic acids. the former heavily concentrated in the 2-position and the latter in the 1- and 3-positions of the triglycerides. Fatty acid composition of milk fat varies somewhat with the composition of diet, particularly the fatty acids which it supplies. Phospholipids, amounting in the aggregate to about 75 mg/100 ml, include phosphatidyl ethanolamine, phosphatidyl choline, phosphatidyl serine, phosphatidyl inositol, and sphingomyelin. The principal mineral constituents of human milk are Na, K, Ca, Mg, P, and Cl. Calcium concentrations reported in various studies vary from 25--35 mg/100 ml. Phosphorus at 13--16 mg/100 ml is much more constant but is lower in proportion to casein and calcium than in milks of most other species. Iron, copper, and zinc contents of human milk vary considerably. A long list of other trace elements has been reported. About 25% of the total nitrogen of human milk represents nonprotein compounds including urea, uric acid, creatine, creatinine, and a large number of amino acids. Of the latter, glutamic acid and taurine are prominent. All of the vitamins, except K, are found in human milk in nutritionally significant concentrations. i hope this helps you out the answer is in it
The Ptolemaic model of the solar system was geocentric, meaning that it was the earth that was at the center of the universe — and everything revolved around it. The main difference between it and other models was that they were heliocentric, where it was the sun at the center of the solar system with the planets revolving around it.

Answer: c. Increased lactate production
Explanation:
The shock causes the deprivation of oxygen, this leads to anaerobic respiration in cells. In anaerobic respiration lactic acid production increases. The lactate get dissociated into lactic acid and hydrogen ions this makes the pH of blood more acidic. The acidic blood ruptures the blood vessels. This anaerobic process leads to the cell death. If enough number of cells die, the organs fails and death may occur.
Water vapor in the atmosphere is the source of water cycle.
