Adaptions are basically add-ons and/or updates while variations are like different types.
If a gene has the base
sequence of CGT AT, examples of a frameshift mutation of this gene are:
Insertion of I
CGI TA T
CGT IA T
CIG TA T
Deletion of G
<span>CTA T</span>
<span>Frameshift mutation is also
called as reading error.</span>
Answer:
The correct answer should be the second option, that is, Onion root tip cells do not undergo anaphase 1.
Anaphase I is a part of meiosis which occurs only in cells involved in reproduction. For example, gametes.
Onion root tip cells undergo mitosis.
The chromosome can be observed using compound microscope.
Thus, all other options are incorrect except second option.
The correct answer is Karl will get sick and Jose will not this time, but neither will get this influenza again since they both will have acquired active immunity to it.
In the case of Jose artificially active immunity has been induced due to vaccination. A vaccine instigates a primary response against the antigen without resulting in any signs of the disease. On the other hand, Karl will acquire active immunity naturally in future, as when an individual get exposed to a live pathogen, he or she develops the disease, and turns immune as an outcome of the primary immune response.
Answer: High Frequency waves by method of compression bone conduction
Explanation: in this, vibration of the bones of the skull and sometimes, arguably soft tissues leads to the production of sounds. The outer and middle ear is bypassed in this method of sound production. Sound reaches the inner ear directly and its a process largely involved in designing hearing aids.
