The correct answer is introns.
Introns are non-coding sequences in the immature mRNA made from DNA transcription. Since they are non-coding, they do not contribute to the final protein that will be translated; therefore introns need to be removed. Introns are removed by RNA splicing; and this is succeeded by 5' capping and adding of poly-A tail.
Answer:
No lactose individuals have two biological parents that are lactose intolerant
Explanation:
In this case lactose intolerance would be coded for a recessive gene (r). if both parents are lactose intolerant the would both be the genotype (rr) . For individual to be lactose intolerant atleast one parent most be lactose tolerant posesing the dominant (R) gene. Which both parents in this example lack.
Mosquitoes have a 6-tube system in their "snout". It's a big big needle with 6 parts to it. 4 of those parts are used to pierce the skin of the human. The other 2 parts are 2 tubes. One of those tubes sends saliva from the mosquito down into the human. The other sends blood up from the human into the mosquito.
Now, unlike some viruses (like dengue and Zikka), HIV cannot replicate inside a mosquito. HIV replicates inside human T-cells...there aren't any of those inside a mosquito gut. Eventually the HIV is destroyed and never makes it to the saliva of the mosquito - so the mosquito can never infect a human with HIV.
Yes, that is called thermal pollution
