Protozoans that Move with Cilia. These protozoans are called Ciliates and have hundreds of tiny cilia which beat in unison to propel them through the water. ... In addition to locomotion, the Paramecium and other ciliates like the Stentor use cilia to sweep food down into their central channel or gullet.

The Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came. Possible since the Moon's composition resembles that of the Earth's mantle and a rapidly spinning Earth could have cast off the Moon from its outer layers. However, the present-day Earth-Moon system should contain "fossil evidence" of this rapid spin and it does not.</span></span>
The following structural changes occur as conducting tubes
become smaller;
- support structures change. The trachea has more hyaline cartilage
than the bronchioles
- epithelium type changes with bronchioles having ciliated
columnar cells with the trachea having tall columnar pseudostratified
- amount of smooth muscle increases as you go lower the respiratory tract
The types of evidence for evolution include
i) Changes in allele frequency over subsequent generations.
ii) When the population in question is examined it does not follow Hardy-Weiberg equilibrium.
iii) Signs of gene flow between populations.
iv) Presence of Sewall-Wright effects or genetic drift in the population.

Established on the data, sickle cell hemoglobin displays altered primary structure and altered quaternary structure; the secondary and tertiary structures may or may not be altered. The sickle cell disease is a cluster of disorders that disturbs hemoglobin, the molecule in red blood cells that transports oxygen to cells all over the body. A person with this disorder have uncharacteristic hemoglobin molecules named hemoglobin S which can interfere with red blood cells into a sickle or crescent shape.
