Answer:
d.The wing-assisted incline running theory postulates that wings were initially used to maintain balance while climbing up slopes.
Explanation:
Two theories were given to explain the origin of avian flight. The top-down theory suggested that the birds' ancestors were tree dwelling species. They took help of wings to glide from tree to tree in order to avoid predator or catch prey. The bottom up theory suggested that the birds' ancestors were ground dwelling species. They took help of wings to maintain a balance and provide a lift for efficient running.
Wing-assisted incline running was a mixture of both the above theories and gave a balanced view point. According to it, birds' ancestors used wings to maintain a balance while running up inclined slopes. The wings helped them to save energy while scaling slopes and eventually a flight mechanism was also developed.
RNA is a single-stranded molecule, which is made up of similar composition as DNA. RNA differs from DNA in the nitrogenous base as it has uracil in place of thymine.
<h3>What is the complementary RNA sequence?</h3>
- A complementary sequence refers to the copy of the strand or template strand of the RNA. The complementary strand will be the copy of the original strand.
- In the complementary base pairing, guanine will be complementary to cytosine and adenine to uracil.
- In the given sequence of RNA, ACC TAG CGA, the complementary sequence formed will be UGG AUC GCU.
Thus, the complementary sequence will be UGG AUC GCU.

Explanation:
Answer:
genes, alleles, dominant, sexually reproducing, two copies, segregate, gametes, independently
Explanation:
The inheritance of biological characteristics is determined by individual units called *genes*, which are passed from parents to offspring. Where two or more *alleles* of the gene for a single trait exist, some alleles may be *dominant* and others may be recessive. In most *sexually reproducing* organisms, each adult has *two copies* of each gene. These genes *segregate* from each other when *gametes* are formed. Alleles for different genes usually segregate *independently* of each other.
