Heres a long answer,hope you don't mind :) A frog's forelegs, also called arms, contain humerus, radius and ulna bones similar to those of a human's. However, a frog's radius and ulna are fused together. Frogs' upper legs contain a femur, and its lower leg bones, the tibia and fibula, are fused together.
Frogs typically have four toes on their front legs and five on their back legs, with lengths varying by different species. Tree frogs who do a lot of climbing and aquatic frogs who require webbed toes for efficient swimming tend to have very long digits. Frogs that live in the mud typically have shorter toes that they utilize as shovels.
The skull of a frog contains five bones and it is connected directly to the spine without a neck vertebrae. At the terminus of the spine, a frog's vertebrae are fused together into a single bone. Due to the lack of ribs, a frog's pelvis is able to slide up and down its spine. This skeletal adaptation is thought to increase jumping ability.
<h2>Answer:</h2>
<u>The property is that </u><u>water expands when it freezes and oxygen is trapped inside</u>
<h2>Explanation:</h2>
Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. The oxygen is present in water under the ice and this oxygen is used for breathing by the marine and aquatic animals.
A fertilized egg usually implants itself and develops in the uterus.
<span>During the prenatal development, fertilized egg adheres to the wall of the uterus. Zygote (fertilized egg) at this stage forms blastocyst. The blastocyst consists of an inner cell mass and the outer layer -the trophoblast. Trophoblast surrounds the inner cell mass and a fluid-filled cavity - blastocoele. Inner cell mass will form embryo and trophoblast gives rise to the placenta.</span>
Answer:
Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor. The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.
