Answer:
What are so called breast-cancer genes, are mutations in two genes: BRCA1 (BReast CAncer gene one) and BRCA2 (BReast CAncer gene two), and are also associated with ovaric cancer. According to the question, these genes are present in the popolation despite surgeries and deaths, and asks why. Surgeries does not eliminate the genes, they eliminate the tumors, and people can still reproduce after that. And also, most people already had offspring before they know they have cancer, so they are inheriting the mutations on the genes anyway.

Answer:
Hip joint
Explanation:
Coxofemoral joint or hip joint. This joint joins the femoral head with the cotyloid cavity of the iliac or coxal bone. Together with the sacrum and the coccyx, both iliacs form a bony waist called the pelvis.
Joint capsule: It is a fibrous cuff that is inserted into the bone perimeter of the cotyloid cavity and the neck of the femur. The capsule is upholstered by a synovial.
Iliofemoral or Bertín: It is inserted in the anterior inferior iliac spine. It is directed downwards through two upper or iliopretrochanteric F.s: it is inserted in front of the facsimiles: F. lower trochanter major or iliopretrochanteric: it is inserted in front of the smaller trochanter.
Pubofemoral: It is inserted into iliopectine eminence, it ends in retrocantineal depression.
Ischio-femoral: It is located on the back of the joint. It originates in the subcotiloid canal and in the periarticular impeller. It ends on the inner side of the greater trochanter (in front of the digital pit).
- Round ligament
- Capsuar ligament.
Round ligament: Measures 3 cm long. It is intraarticular. It extends from the femoral head to the ischiopubial recess of the iliac. It has three fascicles Anterior ends at the anterior end of the recess. Medium ends in the transverse ligament of the Posterior acetabulum passes under the transverse ligament and joins the bone outside the notch.
The round ligament has an artery inside it that supplies the head of the femur. This artery is the branch of the obturator artery. The bottom of the acetabulum, head of the thorn femurllion of the ischium, iliac spine is removed.
Answer: The answer is D. Unless light goes through a medium (like water or air) then light would be at its fastest speed going through a vacuum.
D. Lateral
Explanation:
Lateral faults are not one of the three principal types of faults. A fault is a geologic structure produced as a result of brittle deformation of a rock. It results in blocks of rocks moving relatively one another.
There are three types of faults in a rock:
- Normal fault
- Thrust fault
- Strike slip fault
Normal and reverse faults can also be referred to as dip-slip fault.
- In a strike slip fault, two rocks slide past one another.
- This is different from dip slip faults in which a block slides down or up of another.
