Answer:
Darwin’s findings based:
a. Organisms descended from a common ancestor
Explanation:
Darwin thought of evolution as "descent with modification," a process in which species change and give rise to new species over many generations. He proposed that the evolutionary history of life forms a branching tree with many levels, in which all species can be traced back to an ancient common ancestor.
Answer:
1. In order to fix the bacterial to the slide;
<u>so that it will not be lost during the staining procedure.</u>
<u>so that false impression or result will not be given by the bacteria in water,</u>
<u>Distilled water is used to prevent contamination with impurities e,g metals ions and crystals</u>.
Explanation.
In smear preparation; the bacterial cells should also be well dispersed,so that they do not clumped together to form' big glob'.(large round masses) The later affect clear field view of the bacterial mophology, affected staining, and therefore gives inaccurate results,
Fixing to the slide also affects the morphology of bacterial cells, through shrinking in size, which can lead to loss of structural characteristics and extra-cellular matrixes,
Carbon is found in the non-living part of the hydrosphere, atmosphere, and Geo-sphere, as carbonate (CaCO3) rocks and dead organic matter, such as humus in soil.
Answer:
Compare the carboniferous period to the Devonian period is compared below in details.
Explanation:
In the Devonian Period, woods and land plants developed and vertebrates performed their presentation. Four-legged vertebrates developed during the Carboniferous Period, which created an improvement in the number of land-based bodies. The climate of the continental inland sections was very heated through the Devonian Period and usually quite dry while woods and land plants developed during the Carboniferous period.
