Chloroplast and mitochondria. Because both organelles are roughly the same size and shape as bacteria, have their own double layer membrane, and mitochondria have dna, that they were engulfed by early cells and are now organelles.
Answer:
Some mutations occur during a person’s lifetime in only some of the body’s cells and are not hereditary, so natural selection cannot play a role. Also, many genetic changes have no impact on the function of a gene or protein and are not helpful or harmful
Explanation:
In addition, the environment in which a population of organisms lives is integral to the selection of traits. Some differences introduced by mutations may help an organism survive in one setting but not in another—for example, resistance to a certain bacteria is only advantageous if that bacteria is found in a particular location and harms those who live there.
The answer is (d.) Some scientists believe that prions, tiny proteins much smaller than a cell, that can replicate themselves may be living organisms.
Prions are like viruses, they are not alive making statement B to be true. Prions lack the ability to grow and reproduce. they are dependent on the living cells to replicate. Statement A is absolutely correct while Statement C is somehow wrong. According to scientists, the accurate count of cells in a human is 37.2 Trillion.
