Answer:
<em>Iliopsoas muscle</em>
<em>Lesser trochanter</em>
Explanation:
This two muscles, iliacus and psoas are the most important flexors of the hips. They have different origins: the psoas originates in vertebral bodies (T12, L1-L3) and the iliacus originates in the pelvis (iliac fossa).
Because of psoas origin, it also affects vertebral column position (specially at lumbar lordosis)
During mitosis the chromosomes are being duplicated. which means the chromosomes that are formed during the mitosis is identical to its parents. during the mitosis, the cell udergoes 4 phases. prophase, metaphase, anaphase and lastly the telophase
Answer:
Evidences of evolution are categorized as follows -
- Direct observation of evolutionary change
- Homology and development
- Fossil record and biogeograhy
- Vestigeal organs
Explanation:
Evolutionary changes can be observed either in nature or at a small scale in laboratory by the conditions experimentally generated. For example we can take an organism which has small life span like <em>Drosophila</em> and artificially produce earliest environment like conditions to observe how its development is affected.
Homology supports the common ancestry of the organisms. Homologous structures are formed from a common ancestor. Even if these are structurally different, developmentally they are related.
Fossil records are the most important evidences that document changes in the organisms in the course of time. Sedimentary rocks are the most rich sources of fossils.
Some structural or genetic features serve no apparent purposes. These are called vestigial organs. But as these are present in the organism they show that these are functional in the early forms of that organism.
