Which of the following statements about prey choice is not correct?

A predator can be define as an organism superior and strong enough to kill inferior and weaker organism. This organism kill other organism to obtain it as food. A prey is an organism which is weak and cannot defend itself from the attack of the superior organism.

If the DNA sequence TTCACG is transcribed to AAGGC, what type of mutation has occurred?
kenny6666 [7]
The answer is d. deletion.

If the DNA sequence is TTCACG, it is expected to be transcribed into AAGUGC.
But, it was transcribed into AAGGC. If we count nucleobases, a transcribed sequence has 5 nucleobases, while DNA sequence has 6 nucleobases. These means that deletion happened.
If insertion occurred, there will be 7 nucleobases in transcribed sequence. In substitution or translocation, the transcribed sequence will be the same size, but with different sequence than the DNA sequence.

John had unattached earlobes like his father, but his mother has attached earlobes. What is johns genotype with unattached being
Varvara68 [4.7K]

Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.

John's genotype with unattached being dominant is Aa.

  • Using A to represent the alleles
  • Since his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa).
  • So for John to have an unattached earlobe, his father has to be either AA or Aa.
  • Therefore John's genotype would be Aa
