Answer:

True

Explanation:

The core of the earth consists of molten iron enriched with nickel. This molten iron is mainly responsible for the generation of earths magnetic field. The motion of convection currents creates a geodynamo that produces alternating magnetic field .

The molten core rotates because of rotation of earth on its axis due to which the magnetic poles reverses geographically.

Hence, the given statement is true.

If the percent concentration is equal both inside and outside a cell, water does not move into or out of the cell?
frozen [14]
Not necessarily.
Rather, the particles will continue moving, but the net amount stays the same because they’re moving at a constant rate. The amount of movement does tend to slow down, but it still continues

List the cardiovascular and cardiac features unique to the fetus and describe their role in fetal circulation; explain the fate
STatiana [176]

Cardiovascular features unique to the Fetus:

Fetal circulation is characterized by low systemic vascular resistance (SVR) with high systemic blood flow and high pulmonary vascular resistance with low pulmonary blood flow.

<h3>What is fetal circulation?</h3>

The embryonic circulatory system directs blood that needs oxygen through three shunts, or microscopic tunnels. These shunts are intended to avoid forming organs like the liver and lungs while the fetus is still in the womb.

The foramen ovale, which carries blood from the right atrium of the heart to the left atrium, and the ductus arteriosus, which takes blood from the pulmonary artery to the aorta, are the two shunts that bypass the lungs.

Through the placenta, the mother's blood supplies the fetus with nutrition and oxygen. The enhanced blood divides into three branches as it travels via the umbilical cord to the liver.

What is the correct way to analyze a term that means "softening of the cartilage"?
Ber [7]

Chondromalacia is the synonymous of the cartilage softening (chondro = cartilage, malacia = soft). It's a pathology of softening affecting the joints and more particularly those of the knee (kneecap and femur).

This anomaly can be observed in several circumstances:

• the first is that of direct trauma. It is the cartilaginous lesion occurring before the fracture (fissure) of the cartilage.

• the second is that of common osteoarthritis. It is highly likely that the first stage of osteoarthritis begins with edema (swelling of the cartilage or closed chondropathy) that makes the cartilage less resistant and more vulnerable; this soft cartilage can then crack on its surface (open chondropathy) and these cracks will be more difficult to heal.
