<span>For the answer to the question above, the mRNA stands for messenger RNA. The job of the messenger RNA is to copy the code from the DNA and go through a ribosome so a protein can be created.
rRNA stands or ribosomal RNA. It is essentially the ribosome and is comprised of the large and small subunit. The rRNA allows the mRNA to go through rRNA in order to create the amino acid chain.
tRNA stands for transfer RNA. tRNA brings amino acids to the coordinating codon on the mRNA and matches it to the correct codon.

This law explains that the pair of alleles segregate from each other during meiosis cell division (gamete formation) so that only one allele will be present in each gamete. ... Every organism inherits two alleles for each trait. The two alleles of a pair are different, i.e., one is dominant and one is recessive.
Answer:
The correct answer is option A. "directional selection".
Explanation:
Directional selection is a type of natural selection at which traits with extreme characteristics are selected over traits with medium characteristics. In this case, a long-term climatic change resulted in all seeds that are the fountain of food for finch becoming hard. This will result in a directional selection on bill size in the finch population, where large-billed birds will be selected over small and medium-billed birds.
In simpler terms, the Big Bang theory says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today. In the first second after the universe began, the surrounding temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius). The cosmos contained a vast array of fundamental particles such as neutrons, electrons and protons. These decayed or combined as the universe got cooler. Over time, however, the free electrons met up with nuclei and created neutral atoms. This allowed light to shine through about 380,000 years after the Big Bang.
Answer:
D, organisms that survive long enough to reproduce.
Explanation:
C and D are the best answers. Adaptations and skills other than speed and strength contribute to an organism's survival too, so that means it isn't C. Natural Selection is about how an organism must have useful traits to survive to reproductive stage and successfully reproduce, so it would definitely be D.
