"The frog's back legs are what do most of the work during jumping and landing. A frog's front legs are his shock absorbers when he lands a jump.Aquatic and semi-aquatic frogs live most of their lives in the water or near it. Swimming is an essential skill and leaping is mostly done on level surfaces or for dives. Because the frog's habitat relies on these kinds of movement, the back legs have developed to be much larger than the front legs. <span>Some frogs live in environments where the front legs are just as important as the back legs and are about equal in size. Tree frogs use their front legs heavily. If you watch a tree frog leaping through branches, you can see him reach out to his target with his front legs and feet to take hold of a surface, then draw his back legs onto it. In the case of tree frogs the front and back legs split the work of locomotion almost equally." (animals.pawnation.com).</span>
Answer:
I think Chemical Energy
Explanation:
Photosynthesis is the process by which organisms containing the pigment chlorophyll transform light energy into chemical energy that can be stored in the organic molecular bonds (e.g., sugars).
C. Mutagens causes mutations.
Despite the fact that their numerous abnormalities would ordinarily make them great targets for apoptosis, cancer cells even avoid programmed cell death. As cancer progresses, cells cross the borders of healthy tissue and metastasis (spread) to other locations throughout the body.
Cancer cells:
- First and foremost, cancer is a complex illness, meaning that several faulty genes are implicated. It is not the case that one faulty gene causes a cell to develop into a malignant cell.
- Metastasis refers to the spread of a cancer.
- Uncontrolled growth is a given if there is a constitutively active RTK growth factor. However, the cell has additional defense systems to prevent such unchecked proliferation. If nothing is done, the cell will undergo apoptosis and perish. The development of cancer would not exist.
Some of the typical characteristics of cancer cells include -
- Because they are anchorage independent, cancer cells can grow in both semi-solid and suspension mediums.
- Its proliferation is unaffected by contact with neighboring cells, or contact inhibition.
- Layers of cancerous cells are formed.
- Cancerous cells have a variety of shapes.
- Telomerase is expressed by tumor cells.
- They do not go through apoptosis, have damaged cell cycle regulatory genes, and proliferate uncontrollably.
- For them to grow, angiogenesis is necessary.
