The fossil symbols and mountain belts were helpful because it showed where the land and water dinosaurs were able to live, especially with the non-swimmers in Africa and South America. There is proof of some mountains matching in Western Europe and Greenland.
Explanation:
Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.
The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.

The process that makes it possible for major organs of the body to be formed by 10th week of human development is differentiation.
<u>Explanation:</u>
Human development is started off by the process of fertilization in which the sperm and ovum fuse to form zygote. In human beings fertilization takes place in the oviduct of the female. The zygote that is formed undergoes mitosis to form the embryo.
The embryo then gets embedded in the uterine walls. It continues dividing and differentiating into several organs. Almost all of the organs are formed by tenth week of pregnancy even though they aren’t fully developed.
The embryo has three layers namely ectoderm, mesoderm and endoderm. Ectoderm develops into outermost skin layer, central and peripheral nervous system, eyes and inner ears. Baby’s heart and circulatory system is formed from the mesoderm and the baby’s lungs and intestine develop from the innermost layer called endoderm.
Abrasion is one of the four types of physical weathering.
