Answer:
Fossils of Ambulocetus
Explanation:
Fossils of Ambulocetus show that it was about 3 meters long. It had hind legs which were more suited for swimming than for walking. It could hear very well under water, and its teeth resembled those of modern cetaceans. Its limb anatomy suggests that it was slow on land and in the water.
Humans are more closely related to hogs than hogs are to guinea pigs.
Explanation:
The difference in the amino acid sequence of a protein is used to know the relation between organism i.e. how closely they are related.
It is known that proteins are the result of DNA sequence ie genes of the organism.
The gene or protein is compared between organisms to understand the evolutionary evidence and similarities between them.
The less is the difference the more is the two organisms closely related as in the case of hog and human which have only 1 amino acid difference in their insulin enzyme. While guinea pig is having a difference of 17 amino acids so it is expected to be distantly related.
These relations helps the scientist to resolve the issues of crisis say insulin. They zero out the possibility of extracting the enzyme genes of possible organism and increase the yield.
Generic i think!! Hope this helps
Answer:
D) pH, 7.25; PaCO2 50 mm Hg
Explanation:
For respiratory acidosis confirmation by arterial blood gas values, there should be:
- pH value less than 7.35 <em>(it indicates the acidosis in body but there may be multiple sources of acidosis). </em>
- Partial carbon dioxide pressure greater than 45 mmHg<em> (it indicates that the acidosis source is respiratory)</em>
Therefore a person with values (pH, 7.25; PaCO2 50 mm Hg) would express respiratory acidosis.
The value (pH, 5.0; PaCO2 30 mm Hg) indicates the respiratory alkalosis condition.
Answer:
The reaction in the diagram is right.
Explanation:
In complete combustion, hydrocarbon fuels burn in the presence of high concentration of oxygen that produces carbondioxide gas and water which are releases in the atmosphere. Complete combustion takes place only when there is oxygen present in large amount whereas incomplete combustion occurs when the oxygen in the environment is limited so complete combustion required more oxygen as compared to incomplete combustion.
