Answer: The correct answer is -
A. Sense strand of DNA, substituting uracil for thymine.
Explanation:
Transcription is a process of formation of mRNA (messenger RNA) using a DNA template with the help of enzyme RNA polymerase.
In this process, ribonucleotides are added by RNA polymerase in 5' to 3' direction (that is antiparallel to the direction of template DNA) in a complementary manner.
For Adenine, uracil is added and for Cytosine, Guanine is added in mRNA. This produces the mRNA transcript matching the sense strand of DNA (that is complementary to antisense or template DNA).
Thus, option A) is the right answer.
Answer:
C. the hip bones found in some species of snake
Answer:
This is an example of a symbiotic relationship.
Explanation:
A symbiotic relationship is a close, prolonged association between two or more organisms of different species that normally benefits both members. A good example of symbiotic relationship is a coral and algae, bacteria in the human gut etc
From the information provided, the algae perform photosynthesis, providing the coral with nutrients for feeding and help with calcification. In return, the coral provide the algae with nutrients for it's growth.
Answer: I gotchu.
Explanation:Everything in science relies on proof. In history and arts, things don't work like that because there are not things to proof, there are no theories nor hypothesis.
Answer: Covalent bonds form when atoms share their valence electrons with other atoms to become a more stable molecule.
Explanation: Atoms form covalent bonds as a result of the Octet Rule. The Octet Rule states that all atoms in a molecule need to have eight electrons in their valence shell. This rule can be satisfied by sharing, losing or gaining electrons. A covalent bond allows atoms to satisfy the Octet Rule via sharing.
