olganol [36]

Answer:

The world climate would drastically change.

Explanation:

  • First off, both poles would have rapid expansion, with the freezing of more water near the poles.
  • Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.
  • Deserts would expand and the average temperature would rise.
  • Also, many animals would also die out, because of the change in their environments.
  • Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.

4. Which of the three major types of membrane receptors is often used by bacteria to cause infections?
vodka [1.7K]

Answer:

on channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.

The ability of cells to communicate through chemical signals originated in single cells and was essential for the evolution of multicellular organisms. In multicellular organisms, cells send and receive chemical messages constantly to coordinate the actions of distant organs, tissues, and cells. Cells can receive a message, transfer the information across the plasma membrane, and then produce changes within the cell in response to the message. Single-celled organisms, like yeast and bacteria, communicate with each other to aid in mating and coordination. Cellular communication has developed as a means to communicate with the environment, produce biological changes, and, if necessary, ensure survival.
