Gonna need a bit more information then that if you want an answer.
Answer:
Totipotent Stem Cells - They can differentiate into any type of human body cell or the placenta.
Example: Fertilized egg cells.
Pluripotent Stem Cells are from totipotent cells and can differentiate into any cell in the human body; however, not many are in the placenta.
Example: Blastocyst cells.
Multipotent Stem Cells - They can only differentiate into closely related cells.
Example: Blood stem cell
Unipotent Stem Cells - They can only produce their type of cell.
Example: Skin stem cells (which can only become a new skin stem cell).
Explanation:
If there was not a constant Input of energy into the ecosystem then nothing would have the power to do anything and nothing would be alive. the energy starts with the sun, then goes to plants, then animals that eat the plants, and then the animals that eat those animals, Ect. if this chain reaction did not happen then the plants wouldn't have to power to go through photosynthesis and then we would get no energy. the amount of energy lessen with every chain that it goes through, this is why we get more energy eating plants and why they are healthier.
Natural selection ensures that animals with features that increase their chances of survival are more likely to live and pass those traits on to their progeny.
Animals adapt to their surroundings over a lengthy period of time, which causes those changes. The evolution of adaptations happens across many generations.
<h3>What is an adaptation?</h3>
- A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
- To put it another way, an adaptation is something a species does or has on them that makes it easier for them to locate food, water, mates, and shelter.
- Among the adaptations that helped animals live and prosper on land are:
- Gas exchange using a moist membrane
- The ability to traverse land (limbs instead of fins)
- The capability of body water conservation
- The capability of reproduction and early habitability
- The capacity to endure fast environmental changes
<h3>What are the types of adaptation?</h3>
Depending on the environment, there are three basic types of adaptations: behavioral, structural, and physiological.
- Physiological- When an animal's body's internal mechanisms adapt to its surroundings.
- Structural - Over the course of millions of years of evolution, the animal's bodily features alter.
- Behavioral - Animals adjust their behavior in reaction to their environment.
