Genetic variation enables bacteria to adapt to changes in their environment. Since, bacteria reproduce asexually (binary fission), they can share genes (genetic transfer) via other mechanisms such as conjugation (exchange of genetic material through direct contact between two bacteria), transformation, and transduction(exchange of genetic material via bacteriophages).
Transformation is a process by which bacteria takes in DNA from its environment through the cell membrane.
It is believed that insects are so successful because they have a protective shell or exoskeleton, they are small, and they can fly. Their small size and ability to fly permits escape from enemies and dispersal to new environments. ... In addition, insects can produce large numbers of offspring relatively quickly.
Answer:
a. hemoglobin in red blood cells
Explanation:
Carbon dioxide is constantly produced by cells during cellular metabolism (cellular respiration), generating a concentration difference between the interior of the cell and its exterior (intercellular or interstitial space), and a consequent diffusion of this carbon dioxide into the interstitial fluid. Interstitial fluid now has a higher concentration of carbon dioxide than blood plasma, which causes a diffusion into the capillary. Carbon dioxide is carried by hemoglobin or dissolved in plasma.
