Answer:
Mutation
Explanation:
A mutation is a change in the sequence of genetic letters, called bases, within a molecule of DNA.
<h2>Resilience of bone</h2>
Explanation:
The resilience of bone comes from sacrificial bonds in or between collagen molecules
- Three major functions of bones includes
Providing structural support to the body
Providing protection to vital organs
Providing an environment for marrow (where blood cells are produced)
- There are two types of tissues which bones are composed of:
A hard outer layer called cortical bone which is strong, compact,dense and tough
A spongy inner layer called trabecular bone,this network of trabeculae is lighter and less dense than compact bone as a storage area for minerals (such as calcium)
- Bone is also consists of:
Bone forming cells (osteoblasts and osteocytes)
Bone resorbing cells (osteoclasts)
Non mineral matrix of collagen and noncollagenous proteins (osteoid)
Inorganic mineral salts deposited within the matrix
- Bone ends up being a good example of resilience because it is not static like it is perceived to be
Answer:
A. simple
Explanation:
Asexual reproduction is mainly used by bacteria or small organisms that are too simple to have created a mechanism for sexual reproduction. The advantage of sexual reproduction is the recombination--why do you think you're not an exact copy of your parent? That's because they didn't have you via asexual reproduction.
Why not B: This is the opposite.
Why not C: This isn't necessarily a requisite condition; many bacteria do not live underwater.
Why not D: This is certainly wrong. Bacteria are not extinct, and not looking to be so anytime soon.

Answer:
The correct answer is d. plasma membrane
Explanation:
Bacteria do not have membrane-enclosed organelle like mitochondria to generate ATP but even then it produces ATP because in bacterial plasma membrane acts as the machinery of ATP synthesis.
The ATP synthesis in bacteria is the same as eukaryotes. In prokaryotes, the plasma membrane consists of an electron transport system and NADH helps in building the proton gradient across the plasma membrane.
Then after the proton gradient is built in the plasma membrane the proton tends to come back into the cytoplasm through the ATP synthase complex which generates ATP from ADP and inorganic phosphate.
Therefore the correct answer is d. plasma membrane.
