Explanation:
What are the answer options?
Answer:
This probably because they destroy a given character or give rise to a new one.
Explanation:
Alteration here are the permanent changes found in the DNA structure. And are totally inheritable. An example is the case of sickle cell anaemia and haemophilia. People with this anaemia trait hardly live and reproduce even though they do not show ill effects.
Therefore, this mutation alteration is harmful because they destroy a given character.
Answer:
The answer is below
Explanation:
The possible phenotypes of the mother can be any of the following
AA - A phenotype
AB - AB phenotype (here the mother must have contributed an A gene for it to be possible)
AO - A phenotype (here the mother may have contributed any of the A or O gene.)
BO - B phenotype (here, the mother would only need to contribute O gene for this to be possible)
Answer: Prokaryotic cells
Explanation:
The reason antibiotics are so effective is because they have properties that selectively attack bacteria cells while leaving human cells unscathed.
Bacteria cells are prokaryotic which means that they have cells walls. Human cells on the other hand are Eukaryotic which do not usually have cell walls.
Antibiotics majorly work by attacking the cell walls of bacteria thus making it weak and prone to bursting or easier to destroy by the body's immune system while leaving human cells which do not have the cell walls.
Other antibiotics work in different ways but generally do so by attacking prokaryotic characteristics.
