Answer:
A
Explanation:
Arrows show the flow of energy after photosynthesis takes place
it is found on the reccesive allele of the hemoglobin gene so c
1-no predators,so uncontrolled population growth
2-is a predator that is stronger than the apex predator of the area,or is in a predator free environment so has little to no problem spreading
3-is a toxic animal that breeds quickly,so when eaten can kill what ate it,there for ruining the ecosystem as the predators die from the toxic prey they eat.which can lead to method 1 if not dealt with.
Biological molecule that act as a catalyst in many reactions.
Answer:
The correct answer is providing structure, regulating cell processes and creating movement.
Proteins are large molecules consisting of one or more polypeptide chains. They perform many important functions in the body such as:
- Structural base: they are the building blocks of the cell.
- Movement: They help in locomotion of a cell. For example, actin and myosin present in muscle cells.
- Hormones: Many hormones are protein in nature and help in the control and coordination of the body. For example, insulin and growth hormones are protein in nature.
- Enzymes: Most of the enzymes are protein in nature. Enzymes are biological catalysts which regulate the biochemical reactions taking place in an organism.
- Defense: Antibodies are protein in nature.
- Transport: Proteins form channels across the plasma membrane which facilitate the transport of molecules across the membrane.
In contrast, DNA acts as the genetic material which forms the blueprints of an organism as well as the bases of heredity. They are transcribed into different types of RNA which together synthesize the proteins.
