The head of each femur fits into the deep acetabulum of each os coxae, helping to stabilize the joint.
Acetabulum- The concave surface of the pelvis is known as the acetabulum, sometimes known as the cotyloid cavity. The hip joint is created when the head of the femur connects to the pelvis at the acetabulum.
Os Coxae- The hip bone, also known as the os coxae, innominate bone, pelvic bone, or coxal bone, is a massive, atypical bone that is compressed in the middle and extended above and below.

The diameter paper model is proportionally the same size as the diameter of planet Earth
Answer:
Venus????
Explanation:
The correct comparison of the paper model of the planet Earth to the actual planet Earth is The diameter paper model is proportionally the same size as the diameter of planet Earth. The correct option is 2.
This means that the size of the paper model's diameter is in proportion to the actual diameter of the planet Earth. In other words, the dimensions of the paper model are scaled down or reduced to represent the size of the Earth accurately. This is a common way of creating models to study or represent large objects like planets, as it allows us to visualize and understand their characteristics on a more manageable scale.
The use of scale allows scientists, educators, or anyone interested in understanding Earth's characteristics to work with a more manageable model while preserving the relative proportions and relationships of the planet's features. It also helps in making comparisons and understanding the magnitude of different features of the Earth in a more practical way.

Degrees celsius does a 1.5-gram block of ice increase when 30.0 J of heat energy is added is 9.48 °C.
Heat may be described as strength in transit from a high-temperature object to a decreased-temperature object. An item no longer possesses warmness, the perfect term for the microscopic electricity in an object is internal energy.
Heat is the shape of energy. It comes from the movement of atoms and molecules, which can be the smallest particles that make up all matter. The quicker those debris circulate, the hotter they are. The temperature of an object tells us how speedy its atoms or molecules are transferring. Warm is a form of electricity that is transferred from a substance having a better temperature to a substance having a decreased temperature. The addition of warmth to a substance increases its internal temperature. warmness is described because of the net amount of thermal energy of a gadget.

Progesterone. It is a steroid hormone in charge of sustaining and decidualizing the endometrium.
What is a corpus luteum?
An ovary's corpus luteum is a collection of cells. During the first trimester of pregnancy, it is in charge of producing the hormone progesterone. In females, the corpus luteum is essential for establishing and maintaining pregnancy.
It is a yellow, hormone-secreting body that develops in the ovary at the site of the sac that has discharged after the egg has reached maturity during the process of ovulation. It is located in the female reproductive system. The granulosa cells that border the follicle begin to accumulate lipids and yellow pigments right after ovulation, which causes the development of lutein cells, which make up the corpus luteum.
Progesterone and estrogen are secreted by the corpus luteum. In the event of fertilization, they are crucial in creating changes in the uterus that make it more favorable for embryo-implantation; otherwise, it becomes dormant after about 14 days, resulting in menstruation.

The stability obtained is actually a dynamic equilibrium, where circumstances are mostly uniform yet change is constant. Any system that is in dynamic equilibrium will eventually establish a stable balance that is resistant to external pressures of change.
When such a system is upset, built-in regulatory mechanisms react to the deviations to restore equilibrium; this is an example of feedback regulation.
