Respiration takes place in the mitochondria
Answer:
Antibiotic resistance can evolved in bacterial population in the following ways:
Explanation:
- In response to constant exposure to antibiotics some members of a bacterial population develop some beneficial mutations in some essential genes that gives them survival advantage in terms of food and space over the sensitive bacterial strains and hence they are capable of out-competing the sensitive bacteria.
- This happens due to the process of Natural Selection.
- These genes are called antibiotic resistance genes and bacteria usually carry them on plasmids in form of cassettes where genes resistant to multiple drugs are incorporated. These plasmids are called the MDR or Multi-Drug Resistance Plasmids.
- These resistant plasmids can be easily transferred among bacterial populations by conjugation, transformation or transduction or direct plasmid transfer.
- The resistant genes encode for proteins that render the drug ineffective by promoting their efflux from the cells, preventing their entry into the cell, chemically modifying them such that they become non-functional or altering the target site of the drug.

The basilar membrane is a component of our auditory system wherein it is located on our inner ear, most specifically the cochlea. This organ mainly helps the cochlea on stabilising the sounds that we hear as the vibrations get transmitted from outside to the inner ear via the ossicles.
Answer:
Mother - XAXA
Father - XY
Explanation:
Please see the attached image - complete question
Solution -
In the second cross the female is affected while the male is unaffected
The disease mentioned in the question is dominant X inked which means even one X chromosome can cause the disease. Thus, it will impacts males more than females.
Let the allele representing a diseased X gene be XA
and the allele for normal X gene be X
The offspring have all diseased males, which means that the genotype of affected female will be XAXA
And the genotype of unaffected male will be XY
