<span>The plasma membrane has a type of protein called intrinsic integrals that are embedded in the thickness of the bilayer and moves laterally in the membrane and act on arriving molecules. Their separation results in the destruction of the membrane structure, this protein is the opposite of the peripheral protein and act as filters and mechanisms of active transport in the nutrients and wastes that are expelled outside the cell.</span>
Answer:
portal system is the answer
Answer: The correct answer is- bone structure of the baleen whale and the hummingbird share common ancestor.
Bone structure of the baleen whale and the hummingbird are the homologous organs.
Homologous organs can be described as the organs of different animals, which possess same basic structure but perform different functions.
For example- The flippers of a whale and forelimb of man, bone structure of the baleen whale and the hummingbird.
Baleen Whales and hummingbirds have a basic tetrapod skeletons, which is inherited from a common ancestor. But their bodies have been modified and they have lost parts through natural selection. This results in different adaptation in the form of their respective lifestyles over many years.
65 million years, if I remember correctly
Answer:
Fertilization
Explanation:
Cell division is the process that occurs in all living organisms by which a cell divides into two or more daughter cells. The purpose of vegetative cell division (mitosis) in eukaryotes is maintenance of the cell's genome, growth by cell multiplying and tissue renewal by producing new cell. Reproductive cell division-meiosis is responsible for the formation of gametes for the further reproduction. In prokaryotes it is used as a form of reproduction ( binary fission).
