The cup like structure, in which the femur fits into the hip bone is known as Acetabulum.
the acetabulum is referred to a concave shapoed surface of the pelvis, which have a cup like groove. This groove helps in the binding of the femur head to the hip or the pelvic bone.
The round head of the femur gets fits into this cup shaped structure and forms the hip joint. The acetabulum is formed by the contribution of ischium, ilium and the pubis.
Answer:
True
Explanation:
Reproduction is one of the essential characteristics of all living beings. However, if they reproduce to their full capability, the number of offspring would be higher than the available resource. Due to this reason there is always shortage of resources and hence competition arises among the species.
The fit species survive among all the competing species while the remaining weak species die. As Darwin also said that species have the ability to reproduce uncontrollably therefore, competition among the species for survival is a mode of population regulation
Hence, the given statement is true
Explanation:
When you make the cross. You get
HH HH Hh Hh.
So the genotypic ratio - 2:2 which is also 1:1.
The phenotypic ratio - 4. Since Hh and HH are horned organisms. So they only differ in their genotypic make up.
The over-hunting of the Baleen Whales lowers the population significantly. Since Baleen Whales eat the penguins, less whales equals less penguins eaten; therefore the penguins' population remains about the same until breeding season, where a surplus of baby penguins are produced.
